    Fixed bed gasification is a simple and suitable technology for small scale power generation. One of the disadvantages of this technology is producing tar. So far, tar is not utilized yet and being waste that should be treated into a more useful product. This paper presents a thermodynamic analysis of tar conversion into gas producer through non-catalytic auto-thermal reforming technology. Tar was converted into components, C, H, O, N and S, and then reacted with oxidant such as mixture of air or pure oxygen. Thus, this reaction occurred auto-thermally and reached chemical equilibrium. The sensitivity analysis resulted that the most promising process performance occurred at flow rate of air was reached 43% of stoichiometry while temperature of process is 1100°C, the addition of pure oxygen is 40% and preheating of oxidant flow is 250°C. The yield of the most promising process performance between 11.15-11.17 kmol/h and cold gas efficiency was between 73.8-73.9%.The results of this study indicated that thermodynamically the conversion of tar into producer gas through non-catalytic auto-thermal reformingis more promising

    Experimental results are presented for the autothermal reforming (ATR) of n-hexane, n-tetradecane, benzene and benzene solutions of naphthalene. The tests were run at atmospheric pressure and at moderately high reactant preheat temperatures in the 800-900 K range. Carbon formation lines were determined for paraffinic and aromatic liquids. Profiles were determined for axial bed temperature and composition. Space velocity efforts were assessed, and the locations and types of carbon were recorded. Significant reactive differences between hydrocarbons were identified. Carbon formation characteristics were hydrocarbon specific. The differing behavior of paraffinic and aromatic fuels with respect to their carbon formation may be important in explaining the narrow range of carbon-free operating conditions found in the ATR of number two fuel oil.

  4. Autothermal Processing of Renewable Liquids

    Kruger, Jacob Scott

    molecule are used to propose a reaction mechanism over the catalyst surface. Chapter 4 investigates the reactions that may be occurring in the gas phase and over the alpha-Al2O3 foam monolith support. Significant gas-phase chemistry is likely present in the autothermal reactor, although different temperature gradients between the autothermal reactions and the externally heated tube makes quantification of the amount of homogeneous chemistry in the autothermal system impossible. The alpha-Al2O 3 support may serve as a heat transfer medium and radical quencher (due to its foam structure with small-diameter pores), but not likely acid catalysis, as selectivity to dehydration products was similar both with and without the foam support. Because butanol is another promising liquid intermediate in biomass processing, a series of experiments with butanol in an CPO reactor was also carried out. Chapter 5 compares the four butanol isomers in a CPO reactor over Pt, PtCe, Rh, and RhCe catalysts. The reactivity of tert-butanol was as high or higher than the other alcohols, indicating that the lack of a carbonyl decomposition path does not necessarily in uence the reactivity of the molecule. Rather, the reactivity appeared to be more a function of the initial pyrolysis temperature of the alcohol. Thus, much of the initial chemistry of the higher alcohols in a CPO reactor may be homogeneous. The main function of the catalyst may be to decompose the intermediate carbonyls and alkenes to syngas. To that end, the PtCe had significantly lower reforming activity than the other catalysts, evidenced by the lower selectivity to CO and H2 and generally higher temperatures. Selectivity to syngas and light olefins was high and tunable depending on feed ratios, indicating the potential of CPO to provide petrochemical building blocks from butanol. Chapter 6 combines CPO with a water-gas shift (WGS) stage and investigates the addition of steam to isobutanol for the production of a high-purity H2

    The invention addressed two critical issues in fuel processing for fuel cell application, i.e. catalyst cost and operating stability. The existing state-of-the-art fuel reforming catalyst uses Rh and platinum supported over refractory oxide which add significant cost to the fuel cell system. Supported metals agglomerate under elevated temperature during reforming and decrease the catalyst activity. The catalyst is a perovskite oxide or a Ruddlesden-Popper type oxide containing rare-earth elements, catalytically active firs row transition metal elements, and stabilizing elements, such that the catalyst is a single phase in high temperature oxidizing conditions and maintains a primarily perovskite or Ruddlesden-Popper structure under high temperature reducing conditions. The catalyst can also contain alkaline earth dopants, which enhance the catalytic activity of the catalyst, but do not compromise the stability of the perovskite structure.

  6. On-board reforming of biodiesel and bioethanol for high temperature PEM fuel cells: Comparison of autothermal reforming and steam reforming

    2011-03-01

    In the 21st century biofuels will play an important role as alternative fuels in the transportation sector. In this paper different reforming options (steam reforming (SR) and autothermal reforming (ATR)) for the on-board conversion of bioethanol and biodiesel into a hydrogen-rich gas suitable for high temperature PEM (HTPEM) fuel cells are investigated using the simulation tool Aspen Plus. Special emphasis is placed on thermal heat integration. Methyl-oleate (C19H36O2) is chosen as reference substance for biodiesel. Bioethanol is represented by ethanol (C2H5OH). For the steam reforming concept with heat integration a maximum fuel processing efficiency of 75.6% (76.3%) is obtained for biodiesel (bioethanol) at S/C = 3. For the autothermal reforming concept with heat integration a maximum fuel processing efficiency of 74.1% (75.1%) is obtained for biodiesel (bioethanol) at S/C = 2 and λ = 0.36 (0.35). Taking into account the better dynamic behaviour and lower system complexity of the reforming concept based on ATR, autothermal reforming in combination with a water gas shift reactor is considered as the preferred option for on-board reforming of biodiesel and bioethanol. Based on the simulation results optimum operating conditions for a novel 5 kW biofuel processor are derived.

    The objective of this paper is to design the autothermal reformer (ATR) temperature control by using a coefficient diagram method (CDM). The adiabatic temperature is a main controlled variable of the ATR which is a combination of endothermic and exothermic reactions. The simulation results of control parameters were calculated to maintain the ATR reaction temperature by manipulating air feed flow rate. In this work, two strategies of ATR temperature controller system with and without the feed temperature control of a preheater unit are compared to investigate the appropriate controller system when the change of surrounding temperature is considered as a key disturbance. The results showed that by using the CDM, the stability and robustness for controlling the ATR temperature system were considered to offer the proper control parameters and the designed temperature control of ATR system gave a good performance to maintain the controlled variables and reject the disturbance. Moreover, the ATR control system design with the feed temperature controller can compensate the surrounding temperature better than that without the feed temperature control.

  10. Autothermal reforming of palm empty fruit bunch bio-oil: thermodynamic modelling

    Directory of Open Access Journals (Sweden)

    Lifita N. Tande

    2016-01-01

    Full Text Available This work focuses on thermodynamic analysis of the autothermal reforming of palm empty fruit bunch (PEFB bio-oil for the production of hydrogen and syngas. PEFB bio-oil composition was simulated using bio-oil surrogates generated from a mixture of acetic acid, phenol, levoglucosan, palmitic acid and furfural. A sensitivity analysis revealed that the hydrogen and syngas yields were not sensitive to actual bio-oil composition, but were determined by a good match of molar elemental composition between real bio-oil and surrogate mixture. The maximum hydrogen yield obtained under constant reaction enthalpy and pressure was about 12 wt% at S/C = 1 and increased to about 18 wt% at S/C = 4; both yields occurring at equivalence ratio Φ of 0.31. The possibility of generating syngas with varying H2 and CO content using autothermal reforming was analysed and application of this process to fuel cells and Fischer-Tropsch synthesis is discussed. Using a novel simple modelling methodology, reaction mechanisms were proposed which were able to account for equilibrium product distribution. It was evident that different combinations of reactions could be used to obtain the same equilibrium product concentrations. One proposed reaction mechanism, referred to as the ‘partial oxidation based mechanism’ involved the partial oxidation reaction of the bio-oil to produce hydrogen, with the extent of steam reforming and water gas shift reactions varying depending on the amount of oxygen used. Another proposed mechanism, referred to as the ‘complete oxidation based mechanism’ was represented by thermal decomposition of about 30% of bio-oil and hydrogen production obtained by decomposition, steam reforming, water gas shift and carbon gasification reactions. The importance of these mechanisms in assisting in the eventual choice of catalyst to be used in a real ATR of PEFB bio-oil process was discussed.

  11. Characteristics of hydrogen produced by partial oxidation and auto-thermal reforming in a small methanol reformer

    Horng, Rong-Fang; Chou, Huann-Ming; Lee, Chiou-Hwang; Tsai, Hsien-Te

    This paper investigates experimentally, the transient characteristics of a small methanol reformer using partial oxidation (POX) and auto-thermal reforming (ATR) for fuel cell applications. The parameters varied were heating temperature, methanol supply rate, steady mode shifting temperature, O 2/C (O 2/CH 3OH) and S/C (H 2O/CH 3OH) molar ratios with the main aim of promoting a rapid response and a high flow rate of hydrogen. The experiments showed that a high steady mode shifting temperature resulted in a faster temperature rise at the catalyst outlet and vice versa and that a low steady mode shifting temperature resulted in a lower final hydrogen concentration. However, when the mode shifting temperature was too high, the hydrogen production response was not necessarily improved. It was subsequently shown that the optimum steady mode shifting temperature for this experimental set-up was approximately 75 °C. Further, the hydrogen concentration produced by the auto-thermal process was as high as 49.12% and the volume flow rate up to 23.0 L min -1 compared to 40.0% and 20.5 L min -1 produced by partial oxidation.

    A small ethanol autothermal processor, capable to produce 5 m{sup 3}/h (298,15 K; 101,325 kPa) of hydrogen, was fully sized according to the thermodynamics described and processing products from the ethanol reforming experience. The parameters used to determine all the catalyst amounts were assumed upon state-of-the-art GHSV (Gas Hourly Space Velocity) values and lead a four-bed system implementation, composed by auto thermal reforming catalyst (ATR), high and low temperature shift catalysts (HTS and LTS, respectively) and finally, a carbon monoxide isothermal preferential oxidation catalyst (iso-PrOx). This simulation was solved with EES (Engineering Equation Solver), using its solution algorithm and its thermodynamics chemical species database as well. It follows PEM fuel cell system characteristics (hydrogen supplying conditions, efficiencies and tolerances), and a brief analysis upon global efficiencies for power generation assuming distinct topologies for the generation plant as well different business opportunities for the hydrogen production plant was conducted.

  13. Millisecond autothermal catalytic reforming of carbohydrates for synthetic fuels by reactive flash volatilization

    Science.gov (United States)

    Dauenhauer, Paul Jakob

    Carbohydrates including glucose, cellulose, starch and polyols including glycerol, ethylene glycol and methanol produced in large quantities from biomass are considered as a carbon-based feedstock for high temperature catalytic reforming by catalytic partial oxidation. Autothermal catalytic partial oxidation of methanol, ethylene glycol, and glycerol with Rh and Pt-based catalysts with ceria on alumina foam supports at residence times less than ten milliseconds produced equilibrium selectivity to synthesis gas. The addition of steam at S/C>4 produced selectivity to H2 higher than 80% with little or no selectivity to minor products. In a new process referred to as 'reactive flash volatilization,' catalytic partial oxidation was combined with pyrolysis of biomass by directly impinging particles of cellulose, starch, polyethylene, soy oil, or Aspen (Populous Tremuloides) on an operating Rh-based reforming catalyst at 700-800°C. Solid particles endothermically pyrolyzed to volatile organic compounds which mixed with air and reformed on the catalyst exothermically generating heat to drive the overall process. Particles of ˜250 mum microcrystalline cellulose processed at the conditions of C/O=1.0 on a RhCe/gamma-Al2O3/alpha-Al 2O3 at a residence time of ˜70 milliseconds produced a gaseous effluent stream selecting for 50% H2 and 50% CO with no observable side products other than H2O and CO2, and fuel efficiency. Cellulose, sucrose, and glycerol particle conversion was examined with high-speed photography (1000 frames/second) revealing the formation of a liquid intermediate from cellulose permitting extremely high heat flux (˜1 MW/m 2). Finally, large cellulose rods (7x7x500 mm) were directly pressed against a Rh-based reforming catalyst co-reforming methane with air to examine the processing speed as a function of applied pressure and surface temperature. All experiments demonstrate that solid particles of carbohydrates can reform on Rh-based catalytic foams and

    A simple approach to reaction control for autothermal fuel-reforming systems was proposed and examined. The amount of air supplied to the fuel-reforming system was chosen as the variable in the feedback (closed-loop) control operation, and simply by varying the amount of air supplied, it was attempted to control and stabilize the temperature of the auto-thermal reforming reaction. The amounts of other fuels and water were chosen from pre-determined values by open-loop operation. Since the feedback operation was limited to the air-supply mechanism, it was expected that both the hardware structure of the system and its software configurations could be significantly simplified. The applicability of this simple feedback control operation was confirmed experimentally by using a methanol reformer of the direct-injection type.

    2004-01-01

    'Full text:' A numerical study of the performance of an isooctane catalytic autothermal reformer for a fuel cell automobile has been undertaken. The prototype reformer considered in this study, which is a tubular reformer with three annular sections, was designed and built at the Royal Military College of Canada (RMC). The flow within the reformer was assumed to be steady. The different chemical reactions, along with the reaction rate constants, that take place over the autothermal reforming catalyst (a ceria-based platinum catalyst), were obtained through the analysis and regression of the experimental results from the literature. By neglecting the radial gradients in the concentrations and the velocities of the various species in the flow and in the temperature of the reformer, a one-dimensional numerical model, based on the molar flow rate differential equations and energy equation, was developed to simulate the composition and temperature profiles along the length of the catalyst bed. The results obtained from the numerical model were verified against published results. Numerical results were obtained for a range of total inlet flow rates, different inlet temperatures of the fuel mixture and different oxygen concentrations in feed air at the inlet of the reformer.

  16. Catalytic autothermal reforming of diesel fuel for hydrogen generation in fuel cells. I. Activity tests and sulfur poisoning

    Science.gov (United States)

    Cheekatamarla, Praveen K.; Lane, Alan M.

    Polymer electrolyte membrane (PEM) fuel cells require hydrogen as the fuel source for generating power. Hydrogen can be produced in a fuel processor by the catalytic reforming of hydrocarbons. The objective of this paper is to present an analysis of the autothermal reforming (ATR) of synthetic diesel fuel in an adiabatic reactor using a Pt/ceria catalyst. ATR combines endothermic steam reforming and exothermic partial oxidation reactions in a single unit. This simple system provides higher efficiency and higher energy density than other conventional processes. The product composition as a function of the operating variables and the temperature and concentration profile inside the reactor were studied. Hydrogen was generated under adiabatic conditions by heating the feed mixture and ATR reactor to only 400 °C in contrast to higher temperatures reported in the literature. The stability of the catalyst and its response to the presence of S poison was also investigated.

    This work presents thermodynamic analyses of autothermal processes using five fuels- natural gas, methanol, ethanol, dimethyl ether, and gasoline. Autothermal processes combine exothermic and endothermic reactions. The processes considered here couple endothermic steam reforming with exothermic oxidation to create hydrogen-rich fuel-cell feeds. Of the fuels treated here, methanol, ethanol, and dimethyl ether are pure compounds. Methane simulates natural gas and a mixture of 7% neopentane, 56% 2,4 dimethyl pentane, 7% cyclohexane, 30% ethyl benzene simulates gasoline. In the computations, sufficient oxygen is fed so the energy generated by the oxidation exactly compensates the energy absorbed by the reforming reactions. The analyses calculate equilibrium product concentrations at temperatures from 300 to 1000 K, pressures from 1 to 5 atm, and water-fuel ratios from 1 to 9 times the stoichiometric value. The thermodynamic calculations in this work say that any of the five fuels, when processed autothermally, can give a product leading to a hydrogen-rich feed for fuel cells. The calculations also show that the oxygen-containing substances (methanol, ethanol, and dimethyl ether) require lower temperatures for effective processing than the non-oxygenated fuels (natural gas and gasoline). Lower reaction temperatures also promote products containing less carbon monoxide, a desirable effect. The presence of significant product CO mandates the choice of optimum conditions, not necessarily conditions that produce the maximum product hydrogen content. Using a simple optimum objective function shows that dimethyl ether has the greatest potential product content, followed by methanol, ethanol, gasoline, and natural gas. The calculations point the way toward rational choices of processes for producing fuel-cell feeds of the necessary quality. (author)

    Highlights: • Development and experimental evaluation of Juelich’s novel ATR reactor type. • Constructive integration of steam generation chamber and nozzle for water injection. • Internal steam generator modified to reduce pressure drop to approx. a thirtieth. • Novel concept for ATR heat management proven to be suitable for fuel cell systems. • Reaction conditions during shut-down and start-up optimized to reduce byproducts. - Abstract: This paper describes the development and experimental evaluation of Juelich’s novel reactor type ATR AH2 for autothermal reforming of diesel fuel and kerosene. ATR AH2 overcomes the disadvantages of Juelich’s former reactor generations from the perspective of the fuel cell system by constructively integrating an additional pressure swirl nozzle for the injection of cold water and a steam generation chamber. As a consequence, ATR AH2 eliminates the need for external process configurations for steam supply. Additionally, the internal steam generator has been modified by increasing its cross-sectional area and by decreasing its length. This measure reduces the pressure drop of the steam generator from approx. 500 mbar to roughly a thirtieth. The experimental evaluation of ATR AH2 at steady state revealed that the novel concept for heat management applied in ATR AH2 is suitable for fuel cell systems at any reformer load point between 20% and 120% when the mass fractions of cold water to the newly integrated nozzle are set to values between 40% and 50%. The experimental evaluation of ATR AH2 during start-up and shut-down showed that slight modifications of the reaction conditions during these transient phases greatly reduced the concentrations of ethene, ethane, propene and benzene in the reformate. From the fuel cell system perspective, these improvements provide a very beneficial contribution to longer stabilities for the catalysts and adsorption materials

    Rh doped Ni and Co catalysts, Rh-M/CeO 2 (20 wt %)-Al 2 O 3 (0.2 wt % of Rh; M = Ni or Co, 20 wt %) were synthesized to produce hydrogen via autothermal reforming (ATR) of commercial gasoline at 700 .deg. C under the conditions of a S/C ratio of 2.0, an O/C ratio of 0.84, and a gas hourly space velocity (GHSV) of 20,000 h -1 . The Rh-Ni/CeO 2 (20 wt %)-Al 2 O 3 catalyst (1) exhibited excellent activities, with H 2 and (H 2 +CO) yields of 2.04 and 2.58 mol/mol C, respectively. In addition, this catalyst proved to be highly stable over 100 h without catalyst deactivation, as evidenced by energy dispersive spectroscopy (EDX) and elemental analyses. Compared to 1, Rh-Co/CeO 2 (20 wt %)-Al 2 O 3 catalyst (2) exhibited relatively low stability, and its activity decreased after 57 h. In line with this observation, elemental analyses confirmed that nearly no carbon species were formed at 1 while carbon deposits (10 wt %) were found at 2 following the reaction, which suggests that carbon coking is the main process for catalyst deactivation

    The auxiliary power unit of commercial aircraft is a gas turbine producing electric power with an efficiency of 18 %. This APU can be replaced by a fuel cell system, consisting of an autothermal kerosene reformer and a solid oxide fuel cell (SOFC). The fuel is kerosene Jet A-1. The autothermal reforming of Jet A-1 is practically investigated under variation of steam-to-carbon-ratio, air ratio, space velocity, time in operation and reactor pressure on commercial catalysts. Using stationary system simulation the thermodynamic processes of the device is investigated. Finally, the autothermal reformer and the SOFC consisting of 14 cells are coupled. During this test series, I-V-characteristics are measured, fuel utilisation is calculated and the self-sufficient system operation is shown. (orig.)

    A new multicylinder microchamber reactor is designed on autothermal reforming of methane for hydrogen production, and its performance and thermal behavior, that is, based on the reaction mechanism, is numerically investigated by varying the cylinder radius, cylinder spacing, and cylinder layout. The results show that larger cylinder radius can promote reforming reaction; the mass fraction of methane decreased from 26% to 21% with cylinder radius from 0.25 mm to 0.75 mm; compact cylinder spacing corresponds to more catalytic surface and the time to steady state is decreased from 40 s to 20 s; alteration of staggered and aligned cylinder layout at constant inlet flow rates does not result in significant difference in reactor performance and it can be neglected. The results provide an indication and optimize performance of reactor; it achieves higher conversion compared with other reforming reactors.

    Full Text Available A new multicylinder microchamber reactor is designed on autothermal reforming of methane for hydrogen production, and its performance and thermal behavior, that is, based on the reaction mechanism, is numerically investigated by varying the cylinder radius, cylinder spacing, and cylinder layout. The results show that larger cylinder radius can promote reforming reaction; the mass fraction of methane decreased from 26% to 21% with cylinder radius from 0.25 mm to 0.75 mm; compact cylinder spacing corresponds to more catalytic surface and the time to steady state is decreased from 40 s to 20 s; alteration of staggered and aligned cylinder layout at constant inlet flow rates does not result in significant difference in reactor performance and it can be neglected. The results provide an indication and optimize performance of reactor; it achieves higher conversion compared with other reforming reactors.

    Ni was supported on various types of metal phosphates and their availability in auto-thermal reforming of CH 4 was investigated. It has been found that Ni/(rare earth phosphate), particularly Ni/(Gd, Ce or ErPO 4 ), show high and stable activities. The catalysts also exhibited extremely high resistance against coking. On the other hand, catalysts including Zr, or GaPO 4 or Ca 2 P 2 O 7 were deactivated/inactive and did not show activity eventually. Results of XRD measurements after different treatments revealed that difference of the catalytic behaviour was associated to the stability of metal phosphate during H 2 reduction at high temperature.

    Highlights: • The concept of diesel reforming using hydrogen peroxide was newly proposed. • Characteristics of hydrogen peroxide was experimentally investigated. • Thermodynamically possible operating conditions were analyzed. • Catalytic performance of Ni–Ru/CGO for various diesel compounds was evaluated. • Long-term testing was successfully conducted using Korean commercial diesel. - Abstract: To operate fuel cells effectively in low-oxygen environments, such as in submarines and unmanned underwater vehicles, a hydrogen source with high hydrogen storage density is required. In this paper, diesel autothermal reforming (ATR) with hydrogen peroxide as an alternative oxidant is proposed as a hydrogen production method. Diesel fuel has higher hydrogen density than metal hydrides or other hydrocarbons. In addition, hydrogen peroxide can decompose into steam and oxygen, which are required for diesel ATR. Moreover, both diesel fuel and hydrogen peroxide are liquid states, enabling easy storage for submarine applications. Hydrogen peroxide exhibited the same characteristics as steam and oxygen when used as an oxidant in diesel reforming when pre-decomposition method was used. The thermodynamically calculated operating conditions were a steam-to-carbon ratio (SCR) of 3.0, an oxygen-to-carbon ratio (OCR) of 0.5, and temperatures below 700 °C to account for safety issues associated with hydrogen peroxide use and exothermic reactions. Catalytic activity and stability tests over Ni–Ru (19.5–0.5 wt.%)/Ce 0.9 Gd 0.1 O 2−x were conducted using various diesel compounds. Furthermore, long-term diesel ATR tests were conducted for 200 h using Korean commercial diesel. The degradation rate was 3.67%/100 h without the production of ethylene

    Autothermal fuel reforming (ATR) consists of reacting a hydrocarbon fuel such as natural gas or diesel with steam to produce a hydrogen-rich {open_quotes}reformed{close_quotes} fuel. This work has been designed to investigate the fuel reformation and the product gas combustion under gas turbine conditions. The hydrogen-rich gas has a high flammability with a wide range of combustion stability. Being lighter and more reactive than methane, the hydrogen-rich gas mixes readily with air and can be burned at low fuel/air ratios producing inherently low emissions. The reformed fuel also has a low ignition temperature which makes low temperature catalytic combustion possible. ATR can be designed for use with a variety of alternative fuels including heavy crudes, biomass and coal-derived fuels. When the steam required for fuel reforming is raised by using energy from the gas turbine exhaust, cycle efficiency is improved because of the steam and fuel chemically recuperating. Reformation of natural gas or diesel fuels to a homogeneous hydrogen-rich fuel has been demonstrated. Performance tests on screening various reforming catalysts and operating conditions were conducted on a batch-tube reactor. Producing over 70 percent of hydrogen (on a dry basis) in the product stream was obtained using natural gas as a feedstock. Hydrogen concentration is seen to increase with temperature but less rapidly above 1300{degrees}F. The percent reforming increases as the steam to carbon ratio is increased. Two basic groups of reforming catalysts, nickel - and platinum-basis, have been tested for the reforming activity.

    The integration of mixed ionic electronic conducting (MIEC) membranes for air separation in a small-to-medium scale unit for H2 production (in the range of 650-850 Nm3/h) via auto-thermal reforming of methane has been investigated in the present study. Membranes based on mixed ionic electronic conducting oxides such as Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) give sufficiently high oxygen fluxes at temperatures above 800 °C with high purity (higher than 99%). Experimental results of membrane permeation tests are presented and used for the reactor design with a detailed reactor model. The assessment of the H2 plant has been carried out for different operating conditions and reactor geometry and an energy analysis has been carried out with the flowsheeting software Aspen Plus, including also the turbomachines required for a proper thermal integration. A micro-gas turbine is integrated in the system in order to supply part of the electricity required in the system. The analysis of the system shows that the reforming efficiency is in the range of 62%-70% in the case where the temperature at the auto-thermal reforming membrane reactor (ATR-MR) is equal to 900 °C. When the electric consumption and the thermal export are included the efficiency of the plant approaches 74%-78%. The design of the reactor has been carried out using a reactor model linked to the Aspen flowsheet and the results show that with a larger reactor volume the performance of the system can be improved, especially because of the reduced electric consumption. From this analysis it has been found that for a production of about 790 Nm3/h pure H2, a reactor with a diameter of 1 m and length of 1.8 m with about 1500 membranes of 2 cm diameter is required.

    Highlights: • Modeling of different fuel processors integrated with PEM fuel cell stack. • Steam or autothermal reforming + CO selective methanation or preferential oxidation. • Reforming of different hydrocarbons: gasoline, light diesel oil, natural gas. • 5 kW e net systems comparison via energy efficiency and primary fuel rate consumed. • Highest net efficiency: steam reformer + CO selective methanation based system. - Abstract: The performances of four different auxiliary power unit (APU) schemes, based on a 5 kW e net proton exchange membrane fuel cell (PEM-FC) stack, are evaluated and compared. The fuel processor section of each APU is characterized by a reformer (autothermal ATR or steam SR), a non-isothermal water gas shift (NI-WGS) reactor and a final syngas catalytic clean-up step: the CO preferential oxidation (PROX) reactor or the CO selective methanation (SMET) one. Furthermore, three hydrocarbon fuels, the most commonly found in service stations (gasoline, light diesel oil and natural gas) are considered as primary fuels. The comparison is carried out examining the results obtained by a series of steady-state system simulations in Aspen Plus® of the four different APU schemes by varying the fed fuel. From the calculated data, the performance of CO-PROX is not very different compared to that of the CO-SMET, but the performance of the SR based APUs is higher than the scheme of the ATR based APUs. The most promising APU scheme with respect to an overall performance target is the scheme fed with natural gas and characterized by a fuel processor chain consisting of SR, NI-WGS and CO-SMET reactors. This processing reactors scheme together with the fuel cell section, notwithstanding having practically the same energy efficiency of the scheme with SR, NI-WGS and CO-PROX reactors, ensures a less complex scheme, higher hydrogen concentration in the syngas, lower air mass rate consumption, the absence of nitrogen in the syngas and higher potential

    In this work a compact catalytic reactor was analysed for the ATR of CH 4 as natural gas surrogate. Structured catalysts (commercial honeycomb and foam monoliths) performances in CH 4 processing were studied. In reactor design, great attention has been paid to the thermal integration, in order to obtain a total self-sustainability of the process avoiding additional external heat sources, and improving the plant compactness. Through a heat exchange system integrated in the reactor, water and air streams are preheated by exploiting the heat from exhaust stream, allowing to feed reactants at room temperature as well as cooling products stream at a temperature suitable for further purification stages (Water Gas Shift, Preferential Oxidation). In order to have a very comprehensive process analysis, temperatures and composition were monitored in 6 point along the catalytic bed. The influence of catalytic system geometry and thermal conductivity in the process performances were also analysed. Preliminary tests showed high thermal system efficiency, with a good hydrocarbon conversion at different operating conditions for both catalyst typologies

    Full Text Available This study addresses the catalytic performance of Cu/ZnO/Al2O3/Cr2O3 in low-temperature of autothermal reforming (ATR reaction. Various operating conditions were used to decide the optimum reaction conditions: type of promoter (ZrO2, CeO2, and Cr2O3, precipitation temperature, precipitation pH, operation temperature, molar ratio of O2/CH3OH (O/C, and weight hourly space velocity (WHSV. The catalysts were prepared using the oxalic coprecipitation method. Characterization of the catalyst was conducted using a porosity analyzer, XRD, and SEM. The methanol conversion and volumetric percentage of hydrogen using the best catalyst (Cu/ZnO/Al2O3/Cr2O3 exceeded 93% and 43%, respectively. A catalyst prepared by precipitation at -5 oC and at pH of 1 converted methanol to 40% H2 and less than 3000 ppm CO at reaction temperature of 200 oC. The size and dispersion of copper and the degradation rate and turnover frequency of the catalyst was also calculated. Deactivation of the Cu catalyst at a reaction temperature of 200 oC occurred after 30 h. © 2013 BCREC UNDIP.

    'Full text:' Auto-thermal reformers are used popularly for fuel cell vehicle because they are compact and can start up quickly. On the other hand, steam reformers are used for stationary fuel cell power plant because they are good thermal efficiency. While, there are many cases using the auto- thermal reformer for stationary use with expectation of cost reduction in USA, as well. However, they are still insufficient for its durability, compactness and cost. We have been developing the new type of fuel processing system that is auto-thermal steam reformer (ATSR), which is hybrid of a conventional steam reformer (STR) and a conventional auto-thermal reformer (ATR). In this study, some proto-type of ATSR for field test were designed, tried manufacturing and tested performance and durability. And we have tried to operate with fuel cell stack to evaluate the system interface performance, that is, operability and controllability. (author)

    The present optimization investigation is classified into reforming configuration optimization in one hand and parameter optimization of each configuration on the other hand. Heptane is used as a model component for heavy hydrocarbons. The proposed novel reforming process is basically a Circulating Fluidized-Bed Membrane Reformer (CFBMR) with continuous catalyst regeneration and gas-solid separation. Composite hydrogen selective membranes are used for removing the product hydrogen from the reacting gas mixture and therefore driving the reversible reactions beyond their thermodynamic equilibriums. Dense perovskite oxygen selective membranes are also used to introduce oxygen for the exothermic oxidation of hydrocarbons and carbon. Four configurations are investigated, two of them are with the catalyst regeneration before the gas-solid separation and the other two are with the catalyst regeneration after the gas-solid separation. The optimization of the performance of each configuration is carried out for a number of design and operating parameters as optimization parameters and under both non-autothermal and autothermal reforming conditions. Results show that the autothermal operation with direct contact between cold feeds (water and heptane) and hot circulating catalyst can be the best configuration for efficient hydrogen production with minimum energy consumption. The maximum net hydrogen yield is 16.732 moles of hydrogen per mole of heptane fed, which is 76.05% of the maximum theoretical hydrogen yield of 22. (author)

    A naphta fraction is subjected to a catalytic reforming process in several series-connected reactors. The first reactor is equipped with a moving catalyst bed containing not more the 30% of volume of the total catalyst amount. The other reactors are designed as packed-bed systems. The content of coke deposited on the catalyst of the first reactor owing to the reforming process is maintained at below 1% of weight. This is effected by periodic removal of a proportion of the contaminated catalyst from the bottom part of the bed, by its regeneration and re-feeding to the top part of the bed. This results in prolonged service life of the catalyst and simultaneous improvement of the anti-knock value of the product.

The effect of oxygen enrichment in this experiment was investigated, and the experimental results showed that an increase in oxygen concentration correlated with an increase in the temperature of the catalytic bed; by contrast, this increase in oxygen concentration resulted in a reduction of the startup time of the catalyst. Moreover, the reaction temperature was determined to vary with the position within the catalytic fixed bed. © 2015 BCREC UNDIP.

    The overall objectives of the project were to: (a) develop an economically competitive processing technology for styrene monomer (SM) that would reduce process energy requirements by a minimum 25% relative to those of conventional technology while achieving a minimum 10% ROI; and (b) advance the technology towards commercial readiness. This technology is referred to as OMT (Oxymethylation of Toluene). The unique energy savings feature of the OMT technology would be replacement of the conventional benzene and ethylene feedstocks with toluene, methane in natural gas and air or oxygen, the latter of which have much lower specific energy of production values. As an oxidative technology, OMT is a net energy exporter rather than a net energy consumer like the conventional ethylbenzene/styrene (EB/SM) process. OMT plants would ultimately reduce the cost of styrene monomer which in turn will decrease the costs of polystyrene making it perhaps more cost competitive with competing polymers such as polypropylene.

    A unique autothermal thermophilic aerobic digestion (ATAD) process has been used to convert human excreta to liquid fertilizer in Japan. This study investigated the changes in physicochemical and bacterial community characteristics during the full-scale ATAD process operated for approximately 3 weeks in 2 different years. After initiating simultaneous aeration and mixing using an air-inducing circulator (aerator), the temperature autothermally increased rapidly in the first 1 to 2 days with exhaustive oxygen consumption, leading to a drastic decrease and gradual increase in oxidation-reduction potential in the first 2 days, reached >50°C in the middle 4 to 6 days, and remained steady in the final phase. Volatile fatty acids were rapidly consumed and diminished in the first 2 days, whereas the ammonia nitrogen concentration was relatively stable during the process, despite a gradual pH increase to 9.3. Principal-coordinate analysis of 16S rRNA gene amplicons using next-generation sequencing divided the bacterial community structures into distinct clusters corresponding to three phases, and they were similar in the final phase in both years despite different transitions in the middle phase. The predominant phyla (closest species, dominancy) in the initial, middle, and final phases were Proteobacteria ( Arcobacter trophiarum , 19 to 43%; Acinetobacter towneri , 6.3 to 30%), Bacteroidetes ( Moheibacter sediminis , 43 to 54%), and Firmicutes ( Thermaerobacter composti , 11 to 28%; Heliorestis baculata , 2.1 to 16%), respectively. Two predominant operational taxonomic units (OTUs) in the final phase showed very low similarities to the closest species, indicating that the process is unique compared with previously published ones. This unique process with three distinctive phases would be caused by the aerator with complete aeration. IMPORTANCE Although the autothermal thermophilic aerobic digestion (ATAD) process has several advantages, such as a high degradation

    The fuel processor in which hydrogen is produced from fuels is an important unit in a fuel cell system. The aim of this study is to apply a thermodynamic concept to identify a suitable reforming process for an ethanol-fueled solid oxide fuel cell (SOFC). Three different reforming technologies, i.e., steam reforming, partial oxidation and autothermal reforming, are considered. The first and second laws of thermodynamics are employed to determine an energy demand and to describe how efficiently the energy is supplied to the reforming process. Effect of key operating parameters on the distribution of reforming products, such as H2, CO, CO2 and CH4, and the possibility of carbon formation in different ethanol reformings are examined as a function of steam-to-ethanol ratio, oxygen-to-ethanol ratio and temperatures at atmospheric pressure. Energy and exergy analysis are performed to identify the best ethanol reforming process for SOFC applications. Copyright © 2014 Elsevier Ltd. All rights reserved.

    A mathematical model was developed in the framework of the process simulator Aspen Plus in order to describe the reaction kinetics and performance of a fuel processor used for autothermal reforming of liquid hydrocarbons. Experimental results obtained in the facilities of Argonne National Laboratories (ANL) when reforming isooctane using a ceria-oxide catalyst impregnated with platinum were used in order to validate the reactor model. The reaction kinetics and reaction schemes were taken from published literature and most of the chemical reactions were modeled using the Langmuir-Hinshelwood-Hougen-Watson (LHHW) formulation to account for the effect of adsorption of reactants and products on the active sites of the catalyst. The water-gas-shift (WGS) reactor used to reduce the concentration of CO in the reformate was also modeled. Both reactor models use a simplified formulation for estimating the effectiveness factor of each chemical reaction in order to account for the effect of intraparticle mass transfer limitations on the reactor performance. Since the data in the literature on kinetics of autothermal reforming of liquid hydrocarbons using CeO{sub 2}-Pt catalyst is scarce, the proposed kinetic model for the reaction network was coupled to the sequential quadratic programming (SQP) algorithm implemented in Aspen Plus in order to regress the kinetic constants for the different reactions. The model describes the trend of the experimental data in terms of hydrogen yield and distribution of products with a relative deviation of {+-}15% for reforming temperatures between 600 and 800C and reactor space velocities between 15000 and 150000h{sup -1}.

    Processes are provided for the storage and release of hydrogen by means of dehydrogenation of hydrogen carrier compositions where at least part of the heat of dehydrogenation is provided by a hydrogen-reversible selective oxidation of the carrier. Autothermal generation of hydrogen is achieved wherein sufficient heat is provided to sustain the at least partial endothermic dehydrogenation of the carrier at reaction temperature. The at least partially dehydrogenated and at least partially selectively oxidized liquid carrier is regenerated in a catalytic hydrogenation process where apart from an incidental employment of process heat, gaseous hydrogen is the primary source of reversibly contained hydrogen and the necessary reaction energy.

A brief introduction at the beginning enumerates the advantages of using heavy hydrocarbon fuels onboard to provide hydrogen or syngas for fuel cells such as solid oxide fuel cells (SOFCs). A detailed review of the reforming and processing technologies of diesel and jet fuels is then presented. The advantages of ATR over steam reforming (SR) and partial oxidation reforming (POX) are summarized, and the ATR reaction is analyzed from a thermodynamic point of view. The causes and possible solutions to the major problems existing in ATR reactors, including hot spots, formation of coke, and inhomogeneous mixing of fuel, steam, and air, are reviewed and studied. Designs of ATR reactors are discussed, and three different reactors, one with a fixed bed, one with monoliths, and one with microchannels are investigated.

    Autothermal reforming of methane, combining steam reforming and partial oxidation was carried out with Pt/Al{sub 2}O{sub 3}, Pt/ZrO{sub 2} and Pt/ZrO{sub 2}/Al{sub 2}O{sub 3} catalysts, in the temperature range of 400-900 deg C. The Pt/ZrO{sub 2}/Al{sub 2}O{sub 3} catalyst was found to be the most active and stable at 800 deg C due to the higher resistance to coke formation. The reaction occurs in two simultaneous stages: total combustion of methane and reforming of the unconverted methane with steam and CO{sub 2}, with the O{sub 2} conversion of 100% starting from 450 deg C. The addition of O{sub 2} to the feed increases methane conversion and the catalyst stability, decreasing the H{sub 2} and CO yields due to the enhancement of methane combustion. By manipulating the O{sub 2}/CH{sub 4} ratio to the feed it is possible to achieve higher H{sub 2}/CO ratio and thus maximize hydrogen yield. (author)

  12. A reforming system for co-generation of hydrogen and mechanical work from methanol

    Science.gov (United States)

    Lyubovsky, Maxim; Walsh, Dennis

    The paper describes a reforming system for converting methanol into pure hydrogen. The system is based on an autothermal reforming reactor operating at elevated pressures followed by membrane-based hydrogen separation. The high-pressure membrane retentate stream is combusted and expanded through a turbine generating additional power. Process simulation illustrates the effects of the system operating parameters on performance and demonstrates system reforming efficiency up to ∼90%. When coupled with a PEM fuel cell and an electrical generator, overall fuel to electricity efficiency can be >48% depending upon the efficiency of a PEM fuel cell stack.

    The paper describes a new design for a reforming system for converting hydrocarbon fuels into pure hydrogen. The system is based on an autothermal reforming (ATR) reactor operating at elevated pressures followed by membrane-based hydrogen separation. The high-pressure membrane discharge stream is combusted and expanded through a turbine generating additional power. Process simulation modeling illustrates the effect of pressure and other operating parameters on system performance and demonstrates a system reforming efficiency approaching 80%. When coupled with a PEM fuel cell and an electrical generator, fuel to electricity efficiency is above 40%. Other anticipated benefits of the system include compact size, simplicity in control and fast start up.

    The fuel cell has many potential applications, from power sources for electric hybrid vehicles to small power plants for commercial buildings. The choice of fuel will be critical to the pace of its commercialization. This paper reviews the various liquid fuels being considered as an alternative to direct hydrogen gas for the fuel cell application, presents calculations of the hydrogen and carbon dioxide yields from autothermal reforming of candidate liquid fuels, and reports the product gas composition measured from the autothermal reforming of a synthetic fuel in a micro-reactor. The hydrogen yield for a synthetic paraffin fuel produced by a cobalt-based Fischer-Tropsch process was found to be similar to that of retail gasoline. The advantages of the synthetic fuel are that it contains no contaminants that would poison the fuel cell catalyst, is relatively benign to the environment, and could be transported in the existing fuel distribution system.

    2005-07-01

    In this paper it is demonstrated that the main barrier of large scale heat and electricity production from biomass may be significantly reduced or eliminated by fuel upgrading and thermal treatment in a specially-designed pilot plant autothermal reactor. The process does not require significant amount of additional energy, since the whole process is run autothermal. The process final products are hot flue gases and a solid residue called a 'biocarbon' of LHV of roughly 28 MJ/kg. The properties of the biocarbon were similar, regardless of the input raw fuel type (biomass, waste, sewage sludge, energy crops, etc.). The use of the biocarbon for direct co-combustion with coal does not require installation of any additional feeding or fuel treatment systems at the power plants. Apart from its possible direct combustion, the biocarbon can be also efficiently used as a promising solid energy carrier for other processes (e.g. fuel cells). 6 refs., 6 figs.

    A mathematical model has been devised to represent the process that takes place in a fixed-bed, tubular, adiabatic catalytic reforming reactor. Since its development, the model has been applied to the simulation of a commercial semiregenerative reformer. The development of mass and energy balances for this reformer led to a model that predicts both concentration and temperature profiles along the reactor. A comparison of the model's results with experimental data illustrates its accuracy at predicting product profiles. Simple steps show how the model can be applied to simulate any fixed-bed catalytic reformer.

    2013-01-01

    Catalytic naphtha reforming process is a vital process for refineries due to the production of high-octane components, which is intensely demanded in our modern life. The significance of this industrial process induced researchers to investigate different aspects of catalytic naphtha reforming process intensively. Some of the investigators try to improve this process by representing more effective catalysts, while others try to elucidate its kinetic and deactivation mechanisms and design more efficient reactor setups. The amount of these established papers is so much that may confuse some of the researchers who want to find collective information about catalytic naphtha reforming process. In the present paper, the published studies from 1949 until now are categorized into three main groups including finding suitable catalyst, revealing appropriate kinetic and deactivation model, and suggesting efficient reactor configuration and mode of operation. These studies are reviewed separately, and a suitable reference is provided for those who want to have access to generalized information about catalytic naphtha reforming process. Finally, various suggestions for revamping the catalytic naphtha reforming process have been proposed as a guideline for further investigations

    There has been recent interest in the development of compact fuel processors to produce hydrogen for fuel cell powered vehicles. Gasoline is a promising candidate for distributed or on-board processing because of its high energy density and well-developed infrastructure. A compact fuel processor is under development which utilizes autothermal reforming (ATR) to extract hydrogen from iso-octane, which is used as a surrogate for gasoline. The processor consists of a double-pass packed-bed catalytic reactor to promote partial oxidation, steam reforming, and water-gas-shift reactions. As part of this system development, a commercial computational fluid dynamics (CFD) package was used to model flow and chemical reactions. Reformer performance is presented in terms of hydrogen content in the product stream, reformer efficiency (LHV efficiency) and iso-octane conversion. Results are compared to on-going experimental studies. (author)

  3. Diesel reforming for SOFC auxiliary power units

    The use of a solid-oxide fuel cell (SOFC) to provide auxiliary power for heavy duty trucks can increase fuel efficiency and reduce emissions by reducing engine idling time. The logical fuel of choice for a truck SOFC APU is diesel fuel, as diesel is the fuel of choice for these vehicles. SOFC's that directly oxidize hydrocarbon fuels have lower power densities than do SOFC's that operate from hydrocarbon reformate, and since the SOFC is a costly component, maximizing the fuel cell power density provides benefits in reducing the overall APU system cost. Thus current SOFC APU systems require the reformation of higher hydrocarbons for the most efficient and cost effect fuel cell system. The objective of this research is to develop the technology to enable diesel reforming for SOFC truck APU applications. Diesel fuel can be reformed into a H{sub 2} and CO-rich fuel feed stream for a SOFC by autothermal reforming (ATR), a combination of catalytic partial oxidation (CPOx), and steam reforming (SR). The typical autothermal reformer is an adiabatic, heterogeneous catalytic reactor and the challenges in its design, operation and durability on diesel fuel are manifold. These challenges begin with the vaporization and mixing of diesel fuel with air and steam where fuel pyrolysis can occur and improper mixing leads to hot and cold spots, which contribute to carbon formation and incomplete fuel conversion. The exotherm of the partial oxidation reaction can generate temperatures in excess of 800 C, a temperature at which catalysts rapidly sinter, thus reducing their lifetime. The temperature rise can be reduced by the steam reforming endotherm, but this requires the addition of water along with proper design to balance the kinetic rates. Carbon formation during operation and startup can lead to catalyst deactivation and fouling of downstream components, thus reducing durability of the fuel processor. Water addition helps to reduce carbon formation, but a key issue is

  4. Multi-fuel reformers for fuel cells used in transportation. Phase 1: Multi-fuel reformers

    1994-05-01

    DOE has established the goal, through the Fuel Cells in Transportation Program, of fostering the rapid development and commercialization of fuel cells as economic competitors for the internal combustion engine. Central to this goal is a safe feasible means of supplying hydrogen of the required purity to the vehicular fuel cell system. Two basic strategies are being considered: (1) on-board fuel processing whereby alternative fuels such as methanol, ethanol or natural gas stored on the vehicle undergo reformation and subsequent processing to produce hydrogen, and (2) on-board storage of pure hydrogen provided by stationary fuel processing plants. This report analyzes fuel processor technologies, types of fuel and fuel cell options for on-board reformation. As the Phase 1 of a multi-phased program to develop a prototype multi-fuel reformer system for a fuel cell powered vehicle, the objective of this program was to evaluate the feasibility of a multi-fuel reformer concept and to select a reforming technology for further development in the Phase 2 program, with the ultimate goal of integration with a DOE-designated fuel cell and vehicle configuration. The basic reformer processes examined in this study included catalytic steam reforming (SR), non-catalytic partial oxidation (POX) and catalytic partial oxidation (also known as Autothermal Reforming, or ATR). Fuels under consideration in this study included methanol, ethanol, and natural gas. A systematic evaluation of reforming technologies, fuels, and transportation fuel cell applications was conducted for the purpose of selecting a suitable multi-fuel processor for further development and demonstration in a transportation application.

  5. Gas generation by co-gasification of biomass and coal in an autothermal fluidized bed gasifier

    Wang, Li-Qun; Chen, Zhao-Sheng

    2013-01-01

    In this study, thermochemical biomass and coal co-gasification were performed on an autothermal fluidized bed gasifier, with air and steam as oxidizing and gasifying media. The experiments were completed at reaction temperatures of 875 °C–975 °C, steam-to-biomass ratio of 1.2, and biomass-to-coal ratio of 4. This research aims to determine the effects of reaction temperature on gas composition, lower heating value (LHV), as well as energy and exergy efficiencies, of the product gas. Over the ranges of the test conditions used, the product gas LHV varies between 12 and 13.8 MJ/Nm 3 , and the exergy and energy efficiencies of the product gas are in the ranges of 50.7%–60.8% and 60.3%–85.1%, respectively. The results show that high reaction temperature leads to higher H 2 and CO contents, as well as higher exergy and energy efficiencies of the product gas. In addition, gas LHV decreases with temperature. The molar ratio of H 2 /CO is larger than 1 at temperatures above 925 °C. Our experimental analysis shows that co-gasification of biomass and coal in an autothermal fluidized bed gasifier for gas production is feasible and promising. -- Highlights: • An innovative steam co-gasification process for gas production was proposed. • Co-gasification of biomass and coal in an autothermal fluidized bed gasifier was tested. • High temperature favors H 2 production. • H 2 and CO contents increase, whereas CO 2 and CH 4 levels decrease with increase in T. • Exergy and energy efficiencies of gases increase with increase in T

    Landfill gas (LFG) and biogas can potentially become important feedstocks for renewable hydrogen production. The objectives of this work were: (1) to develop a catalytic process for direct reforming of CH 4 -CO 2 gaseous mixture mimicking LFG, (2) perform thermodynamic analysis of the reforming process using AspenPlus chemical process simulator, (3) determine operational conditions for auto-thermal (or thermo-neutral) reforming of a model CH 4 -CO 2 feedstock, and (4) fabricate and test a bench-scale hydrogen production unit. Experimental data obtained from catalytic reformation of the CH 4 -CO 2 and CH 4 -CO 2 -O 2 gaseous mixtures using Ni-catalyst were in a good agreement with the simulation results. It was demonstrated that catalytic reforming of LFG-mimicking gas produced hydrogen with the purity of 99.9 vol.%. (authors)

  8. Pedagogical reforms of digital signal processing education

    Christensen, Michael

    The future of the engineering discipline is arguably predicated heavily upon appealing to the future generation, in all its sensibilities. The greatest burden in doing so, one might rightly believe, lies on the shoulders of the educators. In examining the causal means by which the profession arrived at such a state, one finds that the technical revolution, precipitated by global war, had, as its catalyst, institutions as expansive as the government itself to satisfy the demand for engineers, who, as a result of such an existential crisis, were taught predominantly theoretical underpinnings to address a finite purpose. By contrast, the modern engineer, having expanded upon this vision and adapted to an evolving society, is increasingly placed in the proverbial role of the worker who must don many hats: not solely a scientist, yet often an artist; not a businessperson alone, but neither financially naive; not always a representative, though frequently a collaborator. Inasmuch as change then serves as the only constancy in a global climate, therefore, the educational system - if it is to mimic the demands of the industry - is left with an inherent need for perpetual revitalization to remain relevant. This work aims to serve that end. Motivated by existing research in engineering education, an epistemological challenge is molded into the framework of the electrical engineer with emphasis on digital signal processing. In particular, it is investigated whether students are better served by a learning paradigm that tolerates and, when feasible, encourages error via a medium free of traditional adjudication. Through the creation of learning modules using the Adobe Captivate environment, a wide range of fundamental knowledge in signal processing is challenged within the confines of existing undergraduate courses. It is found that such an approach not only conforms to the research agenda outlined for the engineering educator, but also reflects an often neglected reality

    Full Text Available In the article was studied the process of reforming the institute of civil service in the countries of the Eurasian space (e.g. Russia, Belarus and Kazakhstan. The integration of national systems of public administration and, in particular, the civil service, is an important factor contributing to the implementation of the centripetal tendencies in the post-Soviet space. The research methodology is based on a combination of comparative legal analysis, historical retrospective method, normalization and scaling, structural-functional and system analysis. A comparison of the legal models of public service was made in research. The author puts forward the hypothesis that it is presence the relationship between the quantitative changes (for example, number of employees of civil service and the dynamics of macroeconomic indicators (e.g. number of employed in the economy. In this regard were observed common trends. On materials of the statistical surveys were considered quantitative changes in national systems of civil service. The study of the socio-demographic characteristics of the public service (gender, age, profession allowed to formulate conclusions about the general and specific trends in the reform of the civil service of the analyzed countries. A number of values were first calculated by the author. The work is intended to become the basis for a broad international research on the development of civil service, which is the central mechanism for implementation the integration in the post-Soviet space.

    This work examines the effect of various hydrocarbons on fuel processor light-off and reforming. Major hydrocarbon fuel constituents, such as aliphatic compounds, napthanes, and aromatics have been compared with the fuel processing performance of blended fuel components and reformulated gasoline to examine synergistic or detrimental effects the fuel components have in a real fuel blend. Short chained aliphatic hydrocarbons tend to have favorable light-off and reforming characteristics for catalytic autothermal reforming compared with longer-chained and aromatic components. Oxygenated hydrocarbons have lower light-off requirements than do pure hydrocarbons. Gas phase oxidation favors higher cetane number fuels, which tend to be longer chained hydrocarbons. Energy consumption during the start-up process shows a large fuel effect. Methanol and dimethylether (DME) show lower start-up energy demands for the fuel processor start-up than do high temperature reforming hydrocarbon fuels such as methane, gasoline and ethanol. Aromatics and longer chained hydrocarbons show a higher tendency for carbon formation, increasing the amount of carbon formed during the light-off phase while the addition of oxygenates tends to lower the carbon formed during the start-up process.

    Sludge stabilization process in terms of operational, environmental and economic indexes is the most important stage of treatment and its disposal. This study was aimed to determine the performance of Autothermal Thermophilic Aerobic Digestion (ATAD) system as one of the low-cost and biocompatible methods of sludge treatment. This study has been done using a laboratory scale Autothermal Thermophilic Aerobic Digestion (ATAD). The reactor was consisted of two polyethylene tanks with a final capacity of 100 L for each tank. Both tanks with all fittings were installed on a metal frame. The variables of study were temperature, dissolved oxygen, pH, volatile organic compounds, total solids, COD and the number of Ascaris eggs and fecal coliforms per gram of dry matter of the sludge. The temperature was measured hourly and the pH and dissolved oxygen were measured and controlled twice per day. One-way ANNOVA was applied to analyze reasults. According to the results, the temperature of sludge increased from 11.7-61.2°C by biological reactions. Pathogen organisms were reduced from 80×106 to 503 in number during 72 h. After 6 days pathogen organisms and Ascaris eggs were removed completely. Volatile organic compounds and COD were reduced 42 and 38.3% respectively during the 6 days. It is concluded that the performance of ATAD in removing organic compounds from wastewater sludge were desirable. Resulted sludge from stabilization process were appropriate for use in agriculture as a soil supplement and met the indexes of class A sludge according to EPA's standards (CFR 40 Part 503).

    Science.gov (United States)

    Hartmann, L.; Lucka, K.; Köhne, H.

    The separation of the evaporation from the high-temperature reaction zone is crucial for the reforming process. Unfavorable mixtures of liquid fuels, water and air lead to degradation by local hot spots in the sensitive catalysts and formation of unwanted by-products in the reformer. Furthermore, the evaporator has to work with dynamic changes in the heat transfer, residence times and educt compositions. By using exothermal pre-reactions in the form of cool flames it is possible to realize a complete and residue-free evaporation of liquid hydrocarbon mixtures. The conditions whether cool flames can be stabilised or not is related to the heat release of the pre-reactions in comparison to the heat losses of the system. Examinations were conducted in a flow reactor at atmospheric pressure and changing residence times to investigate the conditions under which stable cool flame operation is possible and auto-ignition or quenching occurs. An energy balance of the evaporator should deliver the values of heat release by cool flames in comparison to the heat losses of the system. The cool flame evaporation is applied in the design of several diesel-reforming processes (thermal and catalytic partial oxidation, autothermal reforming) with different demands in the heat management and operation range (air ratio λ, steam-to-carbon ratio, SCR). The results are discussed at the end of this paper.

    2013-11-01

    The indirect conversion of natural gas into higher value chemicals and fuels via syngas is superior with regard to efficiency compared to the currently available direct conversion technologies and remains the industrially preferred route. Typically the syngas production route is generally dictated by the H{sub 2}/CO ratio requirements of the downstream synthesis process. Processes such as direct DME synthesis, high-temperature Fischer-Tropsch and acetic acid synthesis require CO rich syngas that is not readily accessible by established technologies like steam methane reforming (SMR) and autothermal reforming of methane (ATR). The CO{sub 2} reforming of methane, also known as dry reforming (DRM), is an attractive alternative technology for the production of CO-rich syngas. This paper gives an overview of the current joint research activities at BASF and hte AG aiming to develop suitable catalysts for CO{sub 2} reforming of methane at elevated pressures with minimized input of process steam. The performance profiles of two newly developed base metal catalysts are presented and discussed. The catalysts exhibit high degrees of methane and CO{sub 2} conversion in combination with an extraordinary coking resistance under high severity process conditions. (orig.)

  16. Novel Auto thermal Reforming Process for Pure Hydrogen Production

    International Nuclear Information System (INIS)

    Chen, Z.; Elnashaie, S.S.E.H.

    2004-01-01

    Steam reforming of heptane for hydrogen production is investigated in a novel Circulating Fluidized Bed Membrane Reformer-Regenerator system (CFBMRR) utilizing a number of hydrogen and oxygen selective membranes. It is shown that although the amount of carbon deposition is significant, the effect on catalyst deactivation is negligible due to the large solid to gas mass feed ratio and the continuous catalyst regeneration in the system. The combustion of the deposited carbon in the catalyst regenerator supplies the heat needed for the endothermic steam reforming as well as the combustion of flammable gases from the riser reformer. Auto thermal operation is achievable for the entire adiabatic reformer-regenerator system when the exothermic heat generated from the regenerator is sufficient to compensate the endothermic heat consumed in the reformer. Multiplicity of the steady states exists in the range of steam to carbon feed ratio of 1.4442.251 mol/mol. The novel configuration has the potential advantages not only with respect to hydrogen production but also energy minimization

  20. Development of sustainable coal to liquid processes: Minimising process CO2 emissions

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Traditional coal-to-liquid (CTL plants are synonymous with the production of carbon dioxide. Coal may be gasified in the presence of steam and oxygen to produce gas comprising carbon dioxide (CO2, carbon monoxide (CO, methane (CH4, hydrogen (H2 and steam (H2O. The gases can be reacted to a myriad of chemicals and fuels via the Fischer-Tropsch (FT reaction. However, excess carbon dioxide is generated via the Water-Gas-Shift reaction during preparation of CO:H2 ratios for FT. Here, a process development is represented on a CHO phase diagram, where unique regions are identified for autothermal operations for coal conversion. Considerations are given to develop idealised processes for the production of liquid chemicals from coal which emit minimal process CO2, require minimal energy input and do not require steam. This is achieved by co-feeding coal with methane and identifying endothermic-exothermic process pairs for methane-coal dry reforming. Furthermore, it is shown that a preferred method to produce liquid fuels from coal is by first creating dimethyl ether (DME as an intermediate, followed by the dehydration of DME to liquid fuels (gasoline range. For this route, via DME, the CO2 emission was found to be four times less than idealised CTL processes.

    Highlights: • A novel thermally coupled reactor in CCR naphtha reforming process is modeled. • The required heat of Naphtha process is attained with toluene hydrodealkylation. • A new kinetic model involving 32 pseudo-component and 84 reactions is proposed. • The aromatics and hydrogen production increase 19% and 23%, respectively. - Abstract: Due to the importance of catalytic naphtha reforming process in refineries, development of this process to attain the highest yield of desired products is crucial. In this study, continuous catalyst regeneration naphtha reforming process with radial flow is coupled with hydrodealkylation of toluene to prevent energy loss while enhancing aromatics and hydrogen yields. In this coupled process, heat is transferred between hot and cold sections (from hydrodealkylation of toluene to catalytic naphtha reforming process) using the process integration method. A steady-state two-dimensional model, which considers coke formation on the catalyst pellets, is developed and 32 pseudo-components with 84 reactions are investigated. Kinetic model utilized for HDA process is homogeneous and non-catalytic. The modeling results reveal an approximate increase of 19% and 23% in aromatics and hydrogen molar flow rates, respectively, in comparison with conventional naphtha reforming process. The improvement in aromatics production evidently indicates that HDA is a suitable process to be coupled with naphtha reforming.

    Full Text Available Hydrogen represents a promising fuel since it is considered as a cleanest energy carrier and also because during its combustion only water is emitted. It can be produced from different kinds of renewable feedstocks, such as ethanol, in this sense hydrogen could be treated as biofuel. Three chemical reactions can be used to achieve this purpose: the steam reforming (SR, the partial oxidation (POX and the autothermal reforming (ATR. In this study, the catalysts implemented in steam reforming of ethanol were reviewed. A wide variety of elements can be used as catalysts for this reaction, such as base metals (Ni, Cu and Co or noble metals (Rh, Pt and Ru usually deposited on a support material that increases surface area and improves catalytic function. The use of Rh, Ni and Pt supported or promoted with CeO2, and/or La2O3 shows excellent performance in ethanol SR catalytic process. The ratio of water to ethanol, reaction temperatures, catalysts loadings, selectivity and activity are also discussed as they are extremely important for high hydrogen yields.

    Highlights: • The effect of O 2 content from 0 to 15% on Ni/SiO 2 are studied for biogas reforming. • The presence of O 2 in biogas improves CH 4 conversion and stability of biogas reforming. • An obvious carbon-resistance effect is observed due to the carbon gasification effect of O 2 in biogas. • The presence of O 2 in biogas greatly helps inhibit the catalyst sintering. - Abstract: We report an energy-efficient biogas reforming process with high and stable methane conversions by O 2 presence. During this biogas reforming process, the effects of various O 2 concentrations in biogas on initial conversions and stability at various temperatures on a Ni/SiO 2 catalyst were detailed investigated. In addition, theoretical energy consumption and conversions were calculated based on the Gibbs energy minimization method to compare with experimental results. Carbon formation and sintering during the reforming process were characterized by thermal gravity analysis, the Brunauer-Emmett-Teller method, X-ray diffraction, and high-resolution transmission electron microscopy to investigate the feasibility of applying this process to an inexpensive nickel catalyst. The results showed that 5% O 2 in biogas improved the CH 4 conversion and stability of biogas reforming. The enhancement of stability was attributed to the inhibited sintering, our first finding, and the reduced carbon deposition at the same time, which sustained a stable conversion of CH 4 , and proved the applicability of base Ni catalyst to this process. Higher O 2 concentrations (⩾10%) in biogas resulted in severe decrease in CO 2 conversion and greater H 2 O productivity. Our proposed biogas reforming process, with a high and stable conversion of CH 4 , reduced energy input, and the applicability to inexpensive base metal catalyst, offers a good choice for biogas reforming with low O 2 concentrations (⩽5%) to produce syngas with high energy efficiency.

    Some commentators view my analyses (Clark, 2012, this issue) as an important step forward in assessing the costs and benefits of eyewitness identification reform. Others suggest that the trade-off between correct identifications lost and false identifications avoided is well-known; that the expected utility model is misspecified; and that the loss of correct identifications due to the use of reformed eyewitness identification procedures is irrelevant to policy decisions, as those correct identifications are the illegitimate product of suggestion and lucky guesses. Contrary to these criticisms, the loss of correct identifications has not been adequately considered in theoretical or policy matters, criticisms regarding the various utilities do not substantively change the nature of the trade-off, and the dismissal of lost correct identifications is based not on data but on an outdated theory of recognition memory. © The Author(s) 2012.

    2012-12-01

    Full Text Available Thus far, the sequencing of political reform processes has been discussed on a separate basis in the context of different scientific debates. Existing analysis in macroeconomics and democracy theory focuses on shock-therapeutic versus gradual reform policies, the succession of specific reform steps or the right timing of reforms. An analytical approach to sequences has been elaborated. Theoretical concepts of social change, which refer to path dependence or the punctuated development of historical sequences, have evolved in the context of institutionalist research. The present article summarises the state of research and extends it with conceptual reflections on the motivation of sequential political action, which can then serve as a starting point for differentiation between sequencing processes in further research.

    Nickel-based catalysts are often used to reform methanol into hydrogen. The preparation and installation of these catalysts are costly and laborious. As an alternative, directly applying catalytic films onto the separator components can improve the manufacturing efficiency. This paper reports the successful deposition of adherent porous NiO-Al 2 O 3 -based catalytic films with well-controlled stoichiometry, using a single-step Aerosol Assisted Chemical Vapour Deposition (AACVD) method. The microstructure, composition and crystalline phase of the as-deposited catalytic films are characterized using a combination of X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier Transform Infrared (FTIR) Spectrometer. The results have demonstrated the capability of AACVD to produce porous NiO-Al 2 O 3 -based catalytic films

    This work presents the simulated equilibrium compositions of ethanol steam reforming (SR), partial oxidation (POX) and auto-thermal reforming (ATR) at a large temperature range, steam-to-ethanol and oxygen-to-ethanol molar ratios. The simulation work shows that the moles of hydrogen yield per mole ethanol are of this order: SR > ATR > POX. The results are compared with other simulation works and fitted models, which show that all the simulation results obtained with different methods agree well with each other. And the fitted models are in highly consistency with very small deviations. Moreover, the thermal-neutral point in corresponding to temperature, steam-to-ethanol and oxygen-to-ethanol mole ratios of ethanol ATR is estimated. The result shows that with the increasing of oxygen-to-ethanol mole ratio, the T-N point moves to higher temperatures; with the increasing of steam-to-ethanol mole ratio, the T-N point moves to lower temperatures. Furthermore, the energy exchanges of the reforming process and the whole process and the thermal efficiencies are also analyzed in the present work and that the energy demands and generated in the whole process are greater than the reforming process can be obtained. Finally, the optimum reaction conditions are selected. -- Highlights: ► The equilibrium compositions simulated by different researchers with different methods are compared. ► The simulation results are fitted with polynomials for convenient reference. ► The energy balance and thermal efficiencies are analyzed. ► The optimum reaction conditions of ethanol POX, SR and ATR for hydrogen production are selected.

  10. Narratives of change and reform processes: global and local transactions in French psychiatric hospital reform after the Second World War.

    2009-02-01

    As with the rest of biomedicine, psychiatry has, since the Second World War, developed under the strong influence of the transnational accumulation of a whole series of practices and knowledge. Anthropology has taught us to pay attention to the transactions between local-level actors and those operating at the global level in the construction of this new world of medicine. This article examines the role played by the recommendations of the WHO Expert Committee of Mental Health in the reform of the French mental health system during the 1950s. Rooted in the experience of practitioners and administrators participating in the process of reforming local psychiatric systems, the recommendations of the WHO Expert Committee developed a new vision of regulating psychiatry, based on professionalism and an idea of a normativity of the doctor-patient relation. This article shows how, by mobilizing the WHO reports' recommendations, French administrators and doctors succeeded in creating a typically French object: "the psychiatric sector", founded on elaborating a new mandate for the psychiatric profession. The article thus questions the deinstitutionalization model as an explanation of transformations of the structure of the French psychiatry system in the post-war period.

    The objective of this article is to offer an overview of the health reform in Ceará focusing on the decentralisation process in the 1990s. The driving factor behind the Brazilian health reform movement was the necessity to reorganise the national health system and overcome inequalities. For the reformists, decentralisation, and together with it the idea of popular participation, is seen as essential to guarantee the fulfilment of the people’s needs and to incorporate their voice in the decision-making processes of the health system. In the state of Ceará, after the 1986 elections, health reform movement members took control over the management of the state Health Secretariat. This is the main cause of the acceleration of the decentralisation process with the transference of responsibility over the management of health care delivery to municipalities. PMID:25729333

    Hydrogen is mainly employed like primary product, for the synthesis of ammonia. The ammonia is synthesized by chemically combining hydrogen and nitrogen under pressure, in the presence of a catalyst. This ammonia is used, for the production of the nitrate fertilizers. Nowadays hydrogen gains more attention mainly because, it is regarded as a future significant fuel by much of experts. The widespread use of hydrogen as source of energy could help to reduce the concern concerning the safety of energy, the total change of climate and the quality of air. Hydrogen is presented then as an excellent alternate initially and as substitute thereafter. It can play a role even more significant than conventional energies. Indeed, it has the advantage of being nonpolluting and it can use the same means of transport as conventional energies. For Algeria, it proves of importance capital. It not only makes it possible to increase and diversify its energy reserves and its exports but also to provide for its energy needs which become increasingly significant. Although hydrogen can be produced starting from a large variety of resources using a range of various technologies, the natural gas is generally preferred and will remain in the near future the principal primary product for the manufacture of hydrogen. Currently the most effective means of production of hydrogen is the Steam Reforming of Natural Gas (SMR). This process is seen as a one of principal technologies for the production of hydrogen. The disadvantages of this process it's that it consumes a great quantity of primary energy and that it releases in the atmosphere the gases that contribute to the warming of the plane. Among the alternatives processes of hydrogen production one can quote solar thermochemical processes. In this study, an exergetic analysis of the process of hydrogen production based on Zn/ZnO redox reactions is presented. In the first part of this study, an exergetic analysis is made for a temperature of the

    Producing energy from biomass and other organic waste residues is essential for sustainable development. Fraunhofer UMSICHT has developed a novel reactor which introduces the Thermo-Catalytic Reforming (TCR®) process. The TCR® is a process which can convert any type of biomass and organic feedstocks into a variety of energy products (char, bio-oil and permanent gases). The aim of this work was to demonstrate this technology using digestate as the feedstock and to quantify the results from the post reforming step. The temperature of a post reformer was varied to achieve optimised fuel products. The hydrogen rich permanent gases produced were maximised at a post reforming temperature of 1023 K. The highly de-oxygenated liquid bio-oil produced contained a calorific value of 35.2 MJ/kg, with significantly improved fuel physical properties, low viscosity and acid number. Overall digestate showed a high potential as feedstock in the Thermo-Catalytic Reforming to produce pyrolysis fuel products of superior quality. Copyright © 2015 Elsevier Ltd. All rights reserved.

  17. Production of synthetic fuels using syngas from a steam hydrogasification and reforming process

    Raju, Arun Satheesh Kumar

    This thesis is aimed at the research, optimization and development of a thermo-chemical process aimed at the production of synthesis gas (mixture of H2 and CO) with a flexible H2 to CO ratio using coupled steam hydrogasification and steam reforming processes. The steam hydrogasification step generates a product gas containing significant amounts of methane by gasifying a carbonaceous feed material with steam and internally generated H2. This product gas is converted to synthesis gas with an excess H2 to CO using the steam reformer. Research involving experimental and simulation work has been conducted on steam hydrogasification, steam reforming and the Fischer-Tropsch reaction. The Aspen Plus simulation tool has been used to develop a process model that can perform heat and mass balance calculations of the whole process using built-in reactor modules and an empirical FT model available in the literature. This model has been used to estimate optimum feed ratios and process conditions for specific feedstocks and products. Steam hydrogasification of coal and wood mixtures of varying coal to wood ratios has been performed in a stirred batch reactor. The carbon conversion of the feedstocks to gaseous products is around 60% at 700°C and 80% at 800°C. The coal to wood ratio of the feedstock does not exert a significant influence on the carbon conversion. The rates of formation of CO, CO 2 and CH4 during gasification have been calculated based on the experimental results using a simple kinetic model. Experimental research on steam reforming has been performed. It has been shown that temperature and the feed CO2/CH4 ratio play a dominant role in determining the product gas H2/CO ratio. Reforming of typical steam hydrogasification product-gas stream has been investigated over a commercial steam reforming catalyst. The results demonstrate that the combined use of steam hydrogasification process with a reformer can generate a synthesis gas with a predetermined H2/CO ratio

    Full Text Available Proceeding from the changes in direct and indirect taxation in the process of the EU tax system reform and the fact that new trends bring about vital social changes, the research in this area could add to the understanding of economic development of these countries. In the EU with its decentralized tax policy, changes in direct and indirect taxation are permanently implemented in the process of tax system reform. Harmonization of direct and indirect taxation in the EU is conducted by means of the adopted community law regulations. In the harmonization of direct taxation there is a tendency towards an increase of the level of fiscal coordination and elimination of barriers to the common market. Thus direct taxation reforms are limited to achieving higher level of coordination and preventing evasion and double taxation. The current policy is the result of the principle according to which fiscal competition has positive effects on reducing consumption and on the EU economic development. In the harmonization process the systems of indirect taxation are aligned particularly with excise duty and value added tax. Fiscal strategies in the reform process are mostly aimed at fiscal coordination, modernization, informative cooperation, evasion reduction and elimination of malpractices in fulfilling a VAT payment liability. Within the excise tax system minimal excise rates are determined and an environmentally-friendly policy is pursued. The main priorities of taxation changes within the harmonization process are in respect of evasion reduction and irrational fiscal competition on the EU market. A study of direct and indirect taxation changes in the process of the tax system reform is highly significant both from the aspect of efficient tax-system functioning, which results in achieving EU macroeconomic goals, and from the aspect of single states' interests in the process of transition and accession.

    2017-11-01

    This paper presents a numerical analysis of heat and mass transfer during the steam reforming of ethane. From a chemical point of view, the reforming process of heavy hydrocarbons, such as ethane, is complex. One of the main issue is a set of undesired chemical reactions that causes the deposition of solid carbon and consequently blocks the catalytic property of a reactor. In the literature a carbon deposition regime is selected by thermodynamical analysis to design safe operation conditions. In the case of Computational Fluid Dynamic (CFD, hereafter) models each control volume should be investigated to determinate if carbon deposition is thermodynamically favourable. In this paper the authors combine equilibrium and kinetics analysis to simulate the steam reforming of methane-ethane rich fuel. The results of the computations were juxtaposed with experimental data for methane steam reforming, and good agreement was found. An analysis based on the kinetics of reactions was conducted to predict the influence of temperature drop and non-equilibrium composition on solid carbon deposition. It was found that strong non-uniform temperature distribution in the reactor causes conditions favourable for carbon deposition at the inlet of the reformer. It was shown that equilibrium calculations, often used in the literature, are insufficient.

  20. Developing an energy efficient steam reforming process to produce hydrogen from sulfur-containing fuels

    Science.gov (United States)

    Simson, Amanda

    Hydrogen powered fuel cells have the potential to produce electricity with higher efficiency and lower emissions than conventional combustion technology. In order to realize the benefits of a hydrogen fuel cell an efficient method to produce hydrogen is needed. Currently, over 90% of hydrogen is produced from the steam reforming of natural gas. However, for many applications including fuel cell vehicles, the use of a liquid fuel rather than natural gas is desirable. This work investigates the feasibility of producing hydrogen efficiently by steam reforming E85 (85% ethanol/15% gasoline), a commercially available sulfur-containing transportation fuel. A Rh-Pt/SiO2-ZrO2 catalyst has demonstrated good activity for the E85 steam reforming reaction. An industrial steam reforming process is often run less efficiently, with more water and at higher temperatures, in order to prevent catalyst deactivation. Therefore, it is desirable to develop a process that can operate without catalyst deactivation at more energy efficient conditions. In this study, the steam reforming of a sulfur-containing fuel (E85) was studied at near stoichiometric steam/carbon ratios and at 650C, conditions at which catalyst deactivation is normally measured. At these conditions the catalyst was found to be stable steam reforming a sulfur-free E85. However, the addition of low concentrations of sulfur significantly deactivated the catalyst. The presence of sulfur in the fuel caused catalyst deactivation by promoting ethylene which generates surface carbon species (coke) that mask catalytic sites. The amount of coke increased during time on stream and became increasingly graphitic. However, the deactivation due to both sulfur adsorption and coke formation was reversible with air treatment at 650°C. However, regenerations were found to reduce the catalyst life. Air regenerations produce exotherms on the catalyst surface that cause structural changes to the catalyst. During regenerations the

    The NRC has engaged in a steady, albeit modest, examination of its preparedness for advanced designs over the past few years. These efforts have included examination of its own guidance and processes as well as co-operation with the US Department of Energy (US DOE) in identifying key issues and potential strategies. But the NRC is constrained in some respects from devoting substantial resources to the development of new or revised regulatory approaches due to statutory requirements that the NRC recover most of its appropriated funds through user fees imposed on the industry. Unless designers are prepared to put up the funds necessary to cover the fees for review of the new designs, the NRC is not able to review them, and licensees of operating facilities paying annual fees may not all be supportive of the NRC expending resources to develop infrastructure for the review of advanced reactor designs. Given the current context, this article will attempt to reflect on the NRC's current framework for licensing, the lessons from NRC's regulations in 10 CFR Part 52 and strategies for adapting to the new demands that may be made on the agency

    A 75-kW methanol reforming fuel cell system, which consists of a fuel cell system and a methanol auto-thermal reforming fuel processor has been developed at Dalian Institute of Chemical Physics, Chinese Academy of Sciences (CAS). The core of the fuel cell system is a group of CO tolerant PEMFC stacks with a double layer composite structured anode. The fuel cell stacks show good CO tolerance even though 140ppm CO was present in the reformate stream during transients. The auto-thermal reforming (ATR) fuel cell processor could adiabatically produce a suitable reformate without external energy consumption. The output of hydrogen-rich reformate was approximately 120Nm{sup 3}h{sup -1} with a H{sub 2} content near 53% and the CO concentrations generally were under 30ppm. The fuel cell system was integrated with the methanol reforming fuel processor and the peak power output of the fuel cell system exceeded 75kW in testing. The hydrogen utilization approached 70% in the fuel cell system. (author)

    This article introduces the energetic macroscopic representation (EMR) as approach for the dynamic modeling of a diesel fuel processing unit. The EMR is the first step toward model-based control structure development. The autothermal fuel processing system containing: heat exchanger, reformer, desulfurization, water gas shift, preferential oxidation and condensation is divided into a multitude simple subblocks. Each subblock describes an elementary step of the fuel conversion, several of these blocks may occur in a single module. Calculations are carried out using two basic principles: mass and energy balances. For model-based control development, it is imperative that the model represents dynamic behavior, therefore temperature and pressure dynamics are taken into account in the model. It is shown that the model is capable to predict the stationary behavior of the entire fuel processing unit correctly by comparison with given data. Predictions regarding reformer heat up, temperature and pressure dynamics are also provided. (author)

    In order to avoid the use of catalysts in the process of auto-thermal reforming, it is possible to adopt a running at high temperature. In this study are presented the results of simulations of an auto-thermal/recuperator hybrid reforming system; these results are obtained with the oxidation model of alkanes developed by Ranzi and Faravelli. An isothermal configuration at high temperature improves the hydrogen yield and avoids the formation of soots. The analysis of the powers to be furnished to assure such an experimental mode, and the global approach of the fuel cell system show that the management of the heat exchanges is a key parameter in this process.

    Sorption enhanced steam methane reforming (SE-SMR) process offers high potential for producing H{sub 2} in fuel cell applications compared to conventional catalytic steam methane reforming (SMR) process. The reactor temperature can significantly affect the performance of the SE-SMR reaction and simultaneous adsorption behavior of CO{sub 2}. Determination of an optimal temperature policy in SE-SMR reactor is therefore an important optimization issue. Multi-stage operation is a possible way to implement optimum temperature policies. In the present work, simulation study has been carried out for multi-stage operation using a mathematical model incorporating basic mechanisms operating in a fixed bed reactor with nonlinear reaction kinetic features of an SE-SMR process. Three cases were considered for implementing the multi-stage concept and the results show that increase in temperature based on a policy leads to considerable improvement in the process performance.

    Full Text Available Romanian society is in a continuous process of change in which all the economic, social, political, civic saw a new dynamic in trying to adapt to specific conditions of the phenomenon of Europeanization (full member of the European Union. The changing of Romanian society requires the public administration reform to be analyzed and disseminated on the following levels: strategic - by which to redefine the role of the state clearly, legally - using larger framework laws, organizational - administrative and fiscal decentralization, cultural - following a change of values and modes of action of public officials, non governmental organizations, the citizen / customer of public service. The term administrative reform is trivial, repetitive and recurrent nets into change, public administration reform is invited to constantly readjust the organization and the action and to clearly state objectives, called sometimes the brakes released, blockages to overcome obstacles of the past which is manifested by the upward trend of the society. Public administration is criticized especially by the public and less by governments in office. Almost general belief is that the administration functions poorly, fulfil its mission in an unsatisfactory manner, but nevertheless has an impact too on community life, economy and society. This paper aims to identify the type of problems that other countries have had to solve and the need hierarchy and management combined in a single system. Understanding the types of problems encountered and they do other countries in this process will shorten the learning cycle for Romania. The objectives of this approach is that the critical analysis of the relationship between public administration reform and administrative capacity based on the literature, outlining the operational model to assess the reform process in our country, the study of democratization (the stage of democratization of public administration modernization strategy

    Full Text Available This paper reviews and assesses the chances for survival and development of the media in Serbia and ib the region, from the perspective of new information and communication technologies (ICT applied in media business. In the paper theoretical method is used and harmonized with the needs of describing the problems and the observed processes and phenomena, as well as empirical method which is used for collecting and interpreting concrete facts and data on the observed processes and phenomena. The starting point lies in the fact that modern media is definitely, more and more, dependent on new technologies. A part of the new technologies is used in the process of collecting, selecting and editing media content, while the other part of the technology is used in the process of dissemination and propulsion of media content to the mass audience, and also in the feedback function as well. The technology revolution, which we describe, started with mp3, jpg and avi files, and continues with internet broadcasting, social networks, cloud technologies and new digital platforms which are used by today's media for distribution of media content. The particularity of the media in the region lies in the fact that they operating in the societes with delay of political and economic transition, so all the productive resources of society, due to this backlog, are slower adapted to the new conditions of business in the digital era. The consequences that have arisen from such dynamics of development make many media in Serbia and the region quite dysfunctional, especially those who were exposed during this transition to long-standing legal, economic and program crises. That is why most of the existing media in Serbia, especially small ones, are unprepared for modernization and they are not ready for re-modeling in accordance with the new technological circumstances.

    After 17 years of experience with the far-reaching 1962 amendments to the law regulating new drugs, a major effort is underway to overhaul the law. Important questions of health policy are involved. An extensive recent study by the Department of Health, Education, and Welfare's Review Panel on New Drug Regulation concluded that the system of regulation that requires governmental pre-market clearance of prescription drugs, based on evidence of safety and effectiveness, is fundamentally sound. But the Review Panel identified four principal deficiencies in the drug approval process: a lack of openness and public accountability, an inadequate science environment at the Food and Drug Administration (FDA), imprecision in the standards and procedures for pre-market approval, and limited FDA authority in the post-marketing period. Former FDA commissioner Donald Kennedy took useful administrative steps to mitigate these problems, but legislation is badly needed. Although the bill that recently passed the Senate is not perfect, it contains substantial improvements over the status quo and merits support.

    Curriculum reform in medical schools continues to be an ever-present and challenging activity in medical education. This paper describes one school's experiences with specific curricular innovations that were developed or adapted and targeted to meet a clear set of curricular goals during the curriculum reform process. Those goals included: (a) promoting active learning and learner engagement; (b) establishing early professional identity; and (c) developing physician competencies in an integrated and contextual manner while allowing for individualized learning experiences for the millennial student. Six specific innovations championed by the school are described in detail. These included Themes in Medical Education, Translational Pillars, Stony Brook Teaching Families, Transition Courses, Educational Continuous Quality Improvement Processes, and our Career Advising Program. Development of the ideas and design of the innovations were done by faculty and student teams. We discuss successes and ongoing challenges with these innovations which are currently in the fourth year of implementation. Our curriculum reform has emphasized the iterative process of curriculum building. Based on our experience, we discuss general and practical guidelines for curriculum innovation in its three phases: setting the stage, implementation, and monitoring for the achievement of intended goals.

  19. Investigating the Plasma-Assisted and Thermal Catalytic Dry Methane Reforming for Syngas Production: Process Design, Simulation and Evaluation

    Directory of Open Access Journals (Sweden)

    Evangelos Delikonstantis

    2017-09-01

    Full Text Available The growing surplus of green electricity generated by renewable energy technologies has fueled research towards chemical industry electrification. By adapting power-to-chemical concepts, such as plasma-assisted processes, cheap resources could be converted into fuels and base chemicals. However, the feasibility of those electrified processes at large scale has not been investigated yet. Thus, the current work strives to compare, for first time in the literature, plasma-assisted production of syngas, from CH4 and CO2 (dry methane reforming, with thermal catalytic dry methane reforming. Specifically, both processes are conceptually designed to deliver syngas suitable for methanol synthesis (H2/CO ≥ 2 in mole. The processes are simulated in the Aspen Plus process simulator where different process steps are investigated. Heat integration and equipment cost estimation are performed for the most promising process flow diagrams. Collectively, plasma-assisted dry methane reforming integrated with combined steam/CO2 methane reforming is an effective way to deliver syngas for methanol production. It is more sustainable than combined thermal catalytic dry methane reforming with steam methane reforming, which has also been proposed for syngas production of H2/CO ≥ 2; in the former process, 40% more CO2 is captured, while 38% less H2O is consumed per mol of syngas. Furthermore, the plasma-assisted process is less complex than the thermal catalytic one; it requires higher amount of utilities, but comparable capital investment.

  20. Accelerating process and catalyst development in reforming reactions with high throughput technologies under industrially relevant conditions

    The generation of hydrogen via reforming of a variety of carbon containing feed-stocks in the presence of water is up to date one of the most versatile technologies for the production of hydrogen and syngas. Although these reforming technologies are in principle well established, understood and commercialized, there are still a number of technological challenges that are not solved up to a satisfactorily degree and there is a constant demand for appropriate answers to the challenges posed. High throughput experimentation can be a valuable tool in helping accelerate the development of suitable solutions on the catalyst and process development side. In order to be able to generate test data that are close or identical to process relevant conditions, hte has developed a new technology portfolio of test technologies named Stage-IV technology. In contrast to earlier developments which address more small scale testing on the basis of catalyst volumes of 1ml up to 10 ml under isothermal conditions, our new technology portfolio offers the advantage of test volumes at sub-pilot scale also realizing reactor dimensions close to technical applications. This does not only ensure a good mimic of the hydrodynamic conditions of the technical scale, but also allows a fingerprinting of features like temperature gradients in the catalyst bed which play a large role for catalyst performance. Apart from catalyst tests with granulates when screening for optimized catalyst compositions, the units are designed to accommodate tests with shaped catalysts. In order to demonstrate how these technologies can accelerate catalyst and process development we have chosen technically challenging application examples: (I) Pre-reforming and reforming of methane based feeds which accelerate coking and catalyst deactivation. Higher reaction pressures, high CO{sub 2} contents in the feedgas (which occur typically in sources like bio-gas or certain types of natural gas), the presence of higher alkanes

    In October 2012, a new law was approved in Uruguay that allows abortion on demand during the first 12 weeks of pregnancy, 14 weeks in the case of rape, and without a time limit when the woman's health is at risk or in the case of foetal anomalies. This paper analyses this legal reform. It is based on 27 individual and group interviews with key informants, and on review of primary documents and the literature. The factors explaining the reform include: secular values in society, favourable public opinion, a persistent feminist movement, effective coalition building, particular party politics, and a vocal public health sector. The content of the new law reflects the tensions between a feminist perspective of women's rights and public health arguments that stop short of fully recognizing women's autonomy. The Uruguayan reform shows that, even in Latin America, abortion can be addressed politically without electoral cost to the parties that promote it. On the other hand, the prevailing public health rationale and conditionalities built into the law during the negotiation process resulted in a law that cannot be interpreted as a full recognition of women's rights, but rather as a modified protectionist approach that circumscribes women's autonomy.

    Tile analysis of heat energy supply in the production of hydrogen by natural gas steam reforming process has been done. The aim of the study is to compare the energy supply system of conventional and nuclear heat. Methodology used in this study is an assessment of literature and analysis based on the comparisons. The study shows that the heat sources of fossil fuels (natural gas) is able to provide optimum operating conditions of temperature and pressure of 850-900 °C and 2-3 MPa, as well as the heat transfer is dominated by radiation heat transfer, so that the heat flux that can be achieved on the catalyst tube relatively high (50-80 kW/m 2 ) and provide high thermal efficiency of about 85 %. While in the system with nuclear energy, due to the demands of safety, process operating at less than optimum conditions of temperature and pressure of 800-850 °C and 4.5 MPa, as well as the heat transfer is dominated by convection heat transfer, so that the heat flux that can be achieved catalyst tube is relatively low (1020 kW/m 2 ) and it provides a low thermal efficiency of about 50 %. Modifications of reformer and heat utilization can increase the heat flux up to 40 kW/m 2 so that the thermal efficiency can reach 78 %. Nevertheless, the application of nuclear energy to hydrogen production with steam reforming process is able to reduce the burning of fossil fuels which has implications for the potential decrease in the rate of CO2 emissions into the environment.

    In a fixed bed membrane reactor evaluations of methane-carbon dioxide reforming over a Ni/{gamma}- Al{sub 2}O{sub 3} catalyst were performed at 773 K, 823 K and 873 K. A to convert natural gas into syngas a fixed-bed reactor associate with a selective membrane was employed, where the operating procedures allowed to shift the chemical equilibrium of the reaction in the direction of the products of the process. Operations under hydrogen permeation, at 873 K, promoted the increase of methane conversion, circa 83%, and doubled the yield of hydrogen production, when compared with operations where no hydrogen permeation occurred.

    For several years, all five medical faculties of Switzerland have embarked on a reform of their training curricula for two reasons: first, according to a new federal act issued in 2006 by the administration of the confederation, faculties needed to meet international standards in terms of content and pedagogic approaches; second, all Swiss universities and thus all medical faculties had to adapt the structure of their curriculum to the frame and principles which govern the Bologna process. This process is the result of the Bologna Declaration of June 1999 which proposes and requires a series of reforms to make European Higher Education more compatible and comparable, more competitive and more attractive for Europeans students. The present paper reviews some of the results achieved in the field, focusing on several issues such as the shortage of physicians and primary care practitioners, the importance of public health, community medicine and medical humanities, and the implementation of new training approaches including e-learning and simulation. In the future, faculties should work on several specific challenges such as: students' mobility, the improvement of students' autonomy and critical thinking as well as their generic and specific skills and finally a reflection on how to improve the attractiveness of the academic career, for physicians of both sexes.

  8. Why infrastructure still matters: unravelling water reform processes in an uneven waterscape in rural Kenya

    Directory of Open Access Journals (Sweden)

    Jeltsje Sanne Kemerink

    2016-08-01

    Full Text Available Since the 1980s, a major change took place in public policies for water resources management. Whereas before governments primarily invested in the development, operation and maintenance of water infrastructure and were mainly concerned with the distribution of water, in the new approach they mainly focus on managing water resources systems by stipulating general frameworks for water allocation. This paper studies the rationales used to justify the water reform process in Kenya and discusses how and to what extent these rationales apply to different groups of water users within Likii catchment in the central part of the country. Adopting a critical institutionalist's perspective, this paper shows how the water resource configurations in the catchment are constituted by the interplay between a normative policy model introduced in a plural institutional context and the disparate infrastructural options available to water users as result of historically produced uneven social relations. We argue that, to progressively redress the colonial legacy, direct investments in infrastructure for marginalized water users and targeting the actual (redistribution of water to the users might be more effective than focusing exclusively on institutional reforms.

  10. Life Cycle Assessment Of Hydrogen Production From Natural Gas Reforming Process

    2010-01-01

    Society has become concerned about the issues of natural resource depletion and environmental degradation. The environmental performance of products or processes has become a key issue, which is why ways to minimize the effects on the environment are investigated. The most effective tool for this purpose is called life cycle assessment (LCA). This concept considers the entire life cycle of product or process. The life cycle of a product begins with the extraction of raw materials from the earth to create the product and ends at the point when all materials are returned to the earth. LCA makes it possible to estimate the cumulative environmental impacts resulting from all stages in the product life cycle, often including impacts not considered in more traditional analyses. Therefore, LCA provides a comprehensive view of the environmental aspects of the product or process and a more accurate picture of the true environmental trade-offs in product selection. In the case of this study, life cycle assessments of hydrogen production via natural gas reforming process are investigated for environmental affect.

    Ferejra Leal Aruda Artur

    2011-01-01

    Full Text Available A possible way to study the history of psychology and psychiatry can be found in Foucault's works about governmentality. In general terms, following his work, we would have two great historical frameworks: 1 the rise of techniques of government based on discipline (termed the Police State in the 16th century; and 2 the new liberal techniques of government which have arisen from the 18th century onwards. Psychology has had a special importance in the latter, especially from the very beginning of the 20th century, acting specifically in the craft of democratic societies. Psychology works not only through disciplining individuals, but also and more especially through their freedom and activity. Our aim here would be to evaluate specifically the Italian and Brazilian movements of psychiatric reform. This analysis will be conducted through examination of the citizenship and freedom concepts present in laws, official documents, some academic texts, and practices. This analysis will be performed considering the kinds and styles of governmentality supposed in these discourses and practices. Our hypothesis would be that in all these processes there is a coexistence of both the old disciplinary processes together with the processes of resistance to them, and the new liberal forms of management.

    2014-05-01

    Full Text Available Due to the demand for high octane gasoline as a transportation fuel, the catalytic naphtha reformer has become one of the most important processes in petroleum refineries. In this research, the steady-state modelling of a catalytic fixed-bed naphtha reforming process to predict the momentous output variables was studied. These variables were octane number, yield, hydrogen purity, and temperature of all reforming reactors. To do such a task, an industrial scale semi-regenerative catalytic naphtha reforming unit was studied and modelled. In addition, to evaluate the developed model, the predicted variables i.e. outlet temperatures of reactors, research octane number, yield of gasoline and hydrogen purity were compared against actual data. The results showed that there is a close mapping between the actual and predicted variables, and the mean relative absolute deviation of the mentioned process variables were 0.38 %, 0.52 %, 0.54 %, 0.32 %, 4.8 % and 3.2 %, respectively.

    This project was focused on developing a catalytic means of producing H2 from raw, ground biomass, such as fast growing poplar trees, willow trees, or switch grass. The use of a renewable, biomass feedstock with minimal processing can enable a carbon neutral means of producing H2 in that the carbon dioxide produced from the process can be used in the environment to produce additional biomass. For economically viable production of H2, the biomass is hydrolyzed and then reformed without any additional purification steps. Any unreacted biomass and other byproduct streams are burned to provide process energy. Thus, the development of a catalyst that can operate in the demanding corrosive environment and presence of potential poisons is vital to this approach. The concept for this project is shown in Figure 1. The initial feed is assumed to be a >5 wt% slurry of ground wood in dilute base, such as potassium carbonate (K2CO3). Base hydrolysis and reforming of the wood is carried out at high but sub-critical pressures and temperatures in the presence of a solid catalyst. A Pd alloy membrane allows the continuous removal of pure , while the retentate, including methane is used as fuel in the plant. The project showed that it is possible to economically produce H2 from woody biomass in a carbon neutral manner. Technoeconomic analyses using HYSYS and the DOE's H2A tool [1] were used to design a 2000 ton day-1 (dry basis) biomass to hydrogen plant with an efficiency of 46% to 56%, depending on the mode of operation and economic assumptions, exceeding the DOE 2012 target of 43%. The cost of producing the hydrogen from such a plant would be in the range of $1/kg H2 to $2/kg H2. By using raw biomass as a feedstock, the cost of producing hydrogen at large biomass consumption rates is more cost effective than steam reforming of hydrocarbons or biomass gasification and can achieve the overall cost goals of the DOE Fuel Cell Technologies Program.

    Producing both hydrogen and high-value carbon nanotubes (CNTs) derived from waste plastics is reported here using a pyrolysis-reforming technology comprising a two-stage reaction system, in the presence of steam and a Ni-Mn-Al catalyst. The waste plastics consisted of plastics from a motor oil container (MOC), commercial waste high density polyethylene (HDPE) and regranulated HDPE waste containing polyvinyl chloride (PVC). The results show that hydrogen can be produced from the pyrolysis-reforming process, but also carbon nanotubes are formed on the catalyst. However, the content of 0.3 wt.% polyvinyl chloride in the waste HDPE (HDPE/PVC) has been shown to poison the catalyst and significantly reduce the quantity and purity of CNTs. The presence of sulfur has shown less influence on the production of CNTs in terms of quantity and CNT morphologies. Around 94.4 mmol H2 g(-1) plastic was obtained for the pyrolysis-reforming of HDPE waste in the presence of the Ni-Mn-Al catalyst and steam at a reforming temperature of 800 °C. The addition of steam in the process results in an increase of hydrogen production and reduction of carbon yield; in addition, the defects of CNTs, for example, edge dislocations were found to be increased with the introduction of steam (from Raman analysis).

    During the past decade, there has been increasing global concern over the rise of anthropogenic CO 2 emission into the Earth's atmosphere (J Air Waste Manage Assoc 53:645-715, 2003). The utilization of CO 2 to produce any valuable product is need of the hour. The production of syngas from CO 2 and CH 4 seems to be one of the promising alternatives in terms of industrial utilization, as it offers several advantages: (a) mitigation of CO 2 , (b) transformation of natural gas and CO 2 into valuable syngas, and (c) producing syngas with H 2 /CO ratio 1 which may further be used for the production of valuable petrochemicals (J Air Waste Manage Assoc 53:645-715, 2003). A conceptual design for the production of synthesis gas by dry reforming of methane is presented here. An economic assessment of this process with an integrated methanol production section as a case was conceptualized and compared with the conventional steam methane reforming route to produce methanol. The economic study indicated that dry reforming of natural gas/methane is a competitive process with lower operating and capital costs in comparison with steam reforming assuming negligible cost of CO 2 import.

    In this study, a novel thermally coupled reactor containing the naphtha reforming process in the endothermic side and the hydrogenation of nitrobenzene to aniline in the exothermic side has been investigated. Considering the higher thermal efficiency as well as the smaller size of the reactor, utilizing the recuperative coupled reactor is given priority. In this novel configuration, the first and the second reactor of the conventional naphtha reforming process have been substituted by the recuperative coupled reactors which contain the naphtha reforming reactions in the shell side, and the hydrogenation reaction in the tube side. The achieved results of this simulation have been compared with the results of the conventional fixed-bed naphtha reforming reactors. Acceptable enhancement can be noticed in the performance of the reactors. The production rate of the high octane aromatics and the consumption rate of the paraffins have improved 17% and 72%, respectively. The conversion of the nitrobenzene is acceptable and the effect of the number of the tubes also has been taken into account. However, the performance of the new configuration needs to be tested experimentally over a range of parameters under practical operating conditions. (author)

    2007-01-01

    The application of an ASM1-based mathematical model for the modeling of autothermal thermophilic aerobic digestion is demonstrated. Based on former experimental results the original ASM1 was extended by the activation of facultative thermophiles from the feed sludge and a new component, the thermophilic biomass was introduced. The resulting model was calibrated in the temperature range of 20-60 degrees C. The temperature dependence of the growth and decay rates in the model is given in terms of the slightly modified Arrhenius and Topiwala-Sinclair equations. The capabilities of the calibrated model in realistic ATAD scenarios are demonstrated with a focus on autothermal properties of ATAD systems at different conditions.

    2006-02-01

    The Advanced Fuel Cycle Initiative program is conducting research on aqueous separations processes for the nuclear fuel cycle. This research includes development of solvent extraction processes for the separation of cesium and strontium from dissolved spent nuclear fuel solutions to reduce the short-term decay heat load. The cesium/strontium strip solution from candidate separation processes will require treatment and solidification for managed storage. Steam reforming is currently being investigated for stabilization of these streams because it can potentially destroy the nitrates and organics present in these aqueous, nitrate-bearing solutions, while converting the cesium and strontium into leach-resistant aluminosilicate minerals, such as pollucite. These ongoing experimental studies are being conducted to evaluate the effectiveness of steam reforming for this application.

    The Environmental Assessment and Review Process Guidelines Order (EARP) was the Canadian federal law governing environmental assessment of projects. EARP had been subject to misinterpretation, had been significantly modified in different directions as a result of numerous court cases, and no longer accurately reflected government policy. Parliament therefore passed the Canadian Environmental Assessment Act (CEAA), which received Royal Assent in 1992, but had still not been proclaimed at the time of the conference, pending a review of draft regulations. CEAA will speed up stalled projects, particularly in the Saskatchewan uranium mining industry, by removing uncertainty and by permitting more focussed, flexible, and consistent public reviews; it defines what kind of government projects require approval; it provides for integration of environmental concerns into federal decision making, e.g. by the AECB; it will allow less expensive and more timely environmental assessments

    This report describes a computational model and the input procedure of HIGHTEX, a computer program for steady-state simulation of the steam-methane reformers used in a nuclear process heat plant. The HIGHTEX program simulates rapidly a single reformer tube, and treats the reactant single-phase in the two-dimensional catalyst bed. Output of the computer program is radial distributions of temperature and reaction products in the catalyst-packed bed, pressure loss of the packed bed, stress in the reformer tube, hydrogen permeation rate through the reformer tube, heat rate of reaction, and heat-transfer rate between helium and process gas. The running time (cpu) for a 9m-long bayonet type reformer tube is 12 min with FACOM-230/75. (auth.)

    Full Text Available This work studies Ni-based catalyst deactivation and regeneration processes in the presence of H2S under a biogas tri-reforming process for hydrogen production, which is an energy vector of great interest. 25 ppm of hydrogen sulfide were continuously added to the system in order to provoke an observable catalyst deactivation, and once fully deactivated two different regeneration processes were studied: a self-regeneration and a regeneration by low temperature oxidation. For that purpose, several Ni-based catalysts and a bimetallic Rh-Ni catalyst supported on alumina modified with CeO2 and ZrO2 were used as well as a commercial Katalco 57-5 for comparison purposes. Ni/Ce-Al2O3 and Ni/Ce-Zr-Al2O3 catalysts almost recovered their initial activity. For these catalysts, after the regeneration under oxidative conditions at low temperature, the CO2 conversions achieved—79.5% and 86.9%, respectively—were significantly higher than the ones obtained before sulfur poisoning—66.7% and 45.2%, respectively. This effect could be attributed to the support modification with CeO2 and the higher selectivity achieved for the Reverse Water-Gas-Shift (rWGS reaction after catalysts deactivation. As expected, the bimetallic Rh-Ni/Ce-Al2O3 catalyst showed higher resistance to deactivation and its sulfur poisoning seems to be reversible. In the case of the commercial and Ni/Zr-Al2O3 catalysts, they did not recover their activity.

    Full Text Available The modern Russian reforms aimed at moving the society to a new stage of development are going through a complicated, contradictory way, with great social costs and zigzags of the political course of power. This poses the task of identifying and overcoming the inhibiting factors in the development of the country. One of the most effective mechanisms of such work is the study of the three-hundred-year experience of Russian reformation and the identification of timeless sociocultural and mental risk factors affecting the nature and content of reforms. This article is devoted to this purpose. In the course of study, we have drawn the conclusions about the deterrent effect on the development of the country of such features of Russian society as its socio-cultural split, absence of internal mechanisms for the self-development of society, lack of a dialogue between government and society, whose relationships are determined by the principle of "antisocial state - anti-state society", mental characteristics of the Russian intelligentsia, which dogmatically implements particular ideas at the expense of economic expediency and common sense, orientation of the ruling elite on the Western values as opposed to national traditions, conservatism and lack of conscious reformative motivation of the masses. This leads to the need to correlate the current reforms not only with the current trends of socio-economic development, but also with the sociocultural foundations of Russian society and the peculiarities of its mentality.

    2015-12-22

    A non-catalytic recuperative reformer has a flue gas flow path for conducting hot flue gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is embedded in the flue gas flow path to permit heat transfer from the hot flue gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, extended surfaces of metal material such as stainless steel or metal alloy that are high in nickel content are included within at least a portion of the reforming mixture flow path.

    Full Text Available One of the most significant procedures in oil refineries is naphtha catalytic reforming unit in which high octane gasoline is gained. Normally, in oil refineries, flow instability in the composition of feedstock can affect the product quality. The aim of the present work was focused on modifications of the final product flow rate and product’s octane number with respect to the modifications of the feedstock composition. The main three reforming reactions investigated, namely; dehydrogenation, dehydrocyclization, and hydrocracking were conducted employing silica supported bimetallic (Pt-Re patented catalyst. Optimization of the catalytic process reaction conditions, i.e.; temperature, hydrogen pressure and liquid hourly space velocity (LHSV was carried out with regard to conversion and selectivity. The optimization results indicated that heavy naphtha component conversion (paraffin’s and naphthenes increases with an increasing in reaction temperature and pressure while decreases with an increase in LHSV. The kinetic study of catalytic reforming reactions reported helped establishing the reaction model explicitly.

    A bibliographic review allows to understand very quickly the stake that the electric-powered vehicle represents. The research of a hydrogen production process answering to the demands of the fuel cell application is then one of the main stakes. The catalytic steam reforming of hydrocarbons or of alcohols is a very promising way. The choices of ethanol and of rhodium based catalysts supported on oxides with strong oxygen mobility will be entirely justified because of the physico-chemical characteristics of the ethanol, of the reaction mechanism, of the cerium based oxide catalyst and of the specifications involved in the fuel cell application.

    The operational limits of a commercial nickel-based catalyst under the conditions of a sorption-enhanced steam-methane reforming process coupled to a Ca/Cu chemical loop are investigated for high-purity H2 production in a cyclic operation. The performance of the reforming catalyst is tested by means of a high number of oxidation-reduction-reforming cycles. After 100 oxidation-reduction cycles, this catalyst retains its exceptional reforming activity. The methane conversion values are close to the thermodynamic equilibrium under very demanding conditions: temperature between 500 °C - 700 °C and mass hourly space velocity of 8.8 kgCH4 h-1 kgcat-1. After 200 cycles, the sample shows reduction in its reforming activity in line with a lower dispersion of the Ni species. Sintering of Ni nanocrystals is evidenced during the oxidation-reduction multi-cycles. The performance of the catalyst after 200 oxidation-reduction cycles mixed with a CaO-based CO2 sorbent is studied under optimal conditions calculated for the sorption-enhanced reforming process coupled to a Ca/Cu cycle (temperature of 650 °C, steam/methane ratio of 4, sorbent/catalyst ratio of 4 and space velocity of 0.75 kgCH4 h-1 kgcat-1). Remarkably, an equilibrium value over 92 vol.% H2 concentration is achieved, highlighting this catalyst as a promising candidate for the next steps of the process development.

    Coral has strong regeneration ability, which has been applied for coral production and biodiversity protection via tissue ball (TB) culture. However, the architecture, morphological processes, and effects of environmental factors on TB formation have not been well investigated. In this study, we first observed TB formation from the cutting tentacle of scleractinia coral Goniopora lobata and uncovered its inner organization and architecture by confocal microscopy. We then found that the cutting tentacle TB could self-organize and reform a solid TB (sTB) in the culture media. Using chemical drug treatment and dissection manipulation approaches, we demonstrated that the mechanical forces for bending and rounding of the cutting fragments came from the epithelial cells, and the cilia of epithelial cell played indispensable roles for the rounding process. Environmental stress experiments showed that high temperature, not CO 2 -induced acidification, affected TB and sTB formation. However, the combination of high temperature and acidification caused additional severe effects on sTB reformation. Our studies indicate that coral TB has strong regeneration ability and therefore could serve as a new model to further explore the molecular mechanism of TB formation and the effects of environmental stresses on coral survival and regeneration.

    An improved fuel processor for fuel cells is provided whereby the startup time of the processor is less than sixty seconds and can be as low as 30 seconds, if not less. A rapid startup time is achieved by either igniting or allowing a small mixture of air and fuel to react over and warm up the catalyst of an autothermal reformer (ATR). The ATR then produces combustible gases to be subsequently oxidized on and simultaneously warm up water-gas shift zone catalysts. After normal operating temperature has been achieved, the proportion of air included with the fuel is greatly diminished.

    The pharmaceutical industry is facing substantial criticism from many directions, including financial barriers to access to drugs in both developed and developing countries, high profits, spending on advertising and marketing, and other issues. Underlying these criticisms are fundamental questions about the value of the current patent-based drug development system. Six major problems with the patent system are (1) recovery of research costs by patent monopoly reduces access to drugs; (2) market demand rather than health needs determines research priorities; (3) resources between research and marketing are misallocated; (4) the market for drugs has inherent market failures; (5) overall investment in drug research and development is too low, compared with profits; and (6) the existing system discriminates against US patients. Potential solutions fall into 3 categories: change in drug pricing through either price controls or tiered pricing; change in drug industry structure through a "buy-out" pricing system or with the public sector acting as exclusive research funder; and change in development incentives through a disease burden incentive system, orphan drug approaches, or requiring new drugs to demonstrate improvement over existing products prior to US Food and Drug Administration approval. We recommend 4 complementary reforms: (1) having no requirement to test new drug products against existing products prior to approval but requiring rigorous comparative postapproval testing; (2) international tiered pricing and systematic safeguards to prevent flow-back; (3) increased government-funded research and buy-out for select conditions; and (4) targeted experiments using other approaches for health conditions in which there has been little progress and innovation over the last few decades.

    Highlights: • Design of iron-based chemical looping process using moving bed for H 2 from CH 4 . • Auto-thermal operation design using thermodynamic rationale for 90% carbon capture. • Cold gas efficiency: 5% points higher than Steam Methane Reforming baseline case. • Net thermal efficiency: 6% points higher than Steam Methane Reforming baseline case. • Sensitivity analysis: Energy recovery scheme, operating pressure, no carbon capture. - Abstract: Hydrogen (H 2 ) is a secondary fuel derived from natural gas. Currently, H 2 serves as an important component in refining operations, fertilizer production, and is experiencing increased utilization in the transportation industry as a clean combustion fuel. In recent years, industry and academia have focused on developing technology that reduces carbon emissions. As a result, there has been an increase in the technological developments for producing H 2 from natural gas. These technologies aim to minimize the cost increment associated with clean energy production. The natural gas processing chemical looping technology, developed at The Ohio State University (OSU), employs an iron-based oxygen carrier and a novel gas–solid counter-current moving bed reactor for H 2 production. Specifically, this study examines the theoretical thermodynamic limits for full conversion of natural gas through iron-based oxygen carrier reactions with methane (CH 4 ), by utilizing simulations generated with ASPEN modeling software. This study initially investigates the reducer and the oxidizer thermodynamic phase diagrams then derives an optimal auto-thermal operating condition for the complete loop simulation. This complete loop simulation is initially normalized for analysis on the basis of one mole of carbon input from natural gas. The H 2 production rate is then scaled to match that of the baseline study, using a full-scale ASPEN simulation for computing cooling loads, water requirements and net parasitic energy consumption.

  5. Towards H2-rich gas production from unmixed steam reforming of methane: Thermodynamic modeling

    Science.gov (United States)

    Lima da Silva, Aline; Müller, Iduvirges Lourdes

    2011-10-01

    In this work, the Gibbs energy minimization method is applied to investigate the unmixed steam reforming (USR) of methane to generate hydrogen for fuel cell application. The USR process is an advanced reforming technology that relies on the use of separate air and fuel/steam feeds to create a cyclic process. Under air flow (first half of the cycle), a bed of Ni-based material is oxidized, providing the heat necessary for the steam reforming that occurs subsequently during fuel/steam feed stage (second half of the cycle). In the presence of CaO sorbent, high purity hydrogen can be produced in a single reactor. In the first part of this work, it is demonstrated that thermodynamic predictions are consistent with experimental results from USR isothermal tests under fuel/steam feed. From this, it is also verified that the reacted NiO to CH4 (NiOreacted/CH4) molar ratio is a very important parameter that affects the product gas composition and decreases with time. At the end of fuel/steam flow, the reforming reaction is the most important chemical mechanism, with H2 production reaching ∼75 mol%. On the other hand, at the beginning of fuel/steam feed stage, NiO reduction reactions dominate the equilibrium system, resulting in high CO2 selectivity, negative steam conversion and low concentrations of H2. In the second part of this paper, the effect of NiOreacted/CH4 molar ratio on the product gas composition and enthalpy change during fuel flow is investigated at different temperatures for inlet H2O/CH4 molar ratios in the range of 1.2-4, considering the USR process operated with and without CaO sorbent. During fuel/steam feed stage, the energy demand increases as time passes, because endothermic reforming reaction becomes increasingly important as this stage nears its end. Thus, the duration of the second half of the cycle is limited by the conditions under which auto-thermal operation can be achieved. In absence of CaO, H2 at concentrations of approximately 73 mol% can

    Today's form of jet engine power comes from what is called a gas turbine engine. This engine is on average 14% efficient and emits great quantities of green house gas carbon dioxide and air pollutants, Le. nitrogen oxides and sulfur oxides. The alternate method being researched involves a reformer and a solid oxide fuel cell (SOFC). Reformers are becoming a popular area of research within the industry scale. NASA Glenn Research Center's approach is based on modifying the large aspects of industry reforming processes into a smaller jet fuel reformer. This process must not only be scaled down in size, but also decrease in weight and increase in efficiency. In comparison to today's method, the Jet A fuel reformer will be more efficient as well as reduce the amount of air pollutants discharged. The intent is to develop a 10kW process that can be used to satisfy the needs of commercial jet engines. Presently, commercial jets use Jet-A fuel, which is a kerosene based hydrocarbon fuel. Hydrocarbon fuels cannot be directly fed into a SOFC for the reason that the high temperature causes it to decompose into solid carbon and Hz. A reforming process converts fuel into hydrogen and supplies it to a fuel cell for power, as well as eliminating sulfur compounds. The SOFC produces electricity by converting H2 and CO2. The reformer contains a catalyst which is used to speed up the reaction rate and overall conversion. An outside company will perform a catalyst screening with our baseline Jet-A fuel to determine the most durable catalyst for this application. Our project team is focusing on the overall research of the reforming process. Eventually we will do a component evaluation on the different reformer designs and catalysts. The current status of the project is the completion of buildup in the test rig and check outs on all equipment and electronic signals to our data system. The objective is to test various reformer designs and catalysts in our test rig to determine the most

Since 1994 policy targets to transfer land to black farmers have not been met. Of the 2005 target to transfer about 25 million ha of commercial farmland to black farmers by 2014, less than 5 million ha. have been transferred for commercial use. Some studies report failure rates in resettlement projects of up to 90%. To account for the failures, revisions of policies and amendments to legislations have been proposed within a political environment that is becoming increasingly intolerant to slow progress in land transfers and to resettlement failures. Aim: Against this environment, this paper presents a typology for understanding and evaluating important elements of the land reform project in order to influence progress in the process. Setting: The study adopts a historical review of land reform processes in post-colonial Kenya and Zimbabwe in order to identify potential challenges and key lessons for South Africa. Methods: Hence, using institutional and historical analytical lenses in exploring different narratives, the paper reviews reported failures and successes in land reform policy cases from the selected countries. From an institutional framework, prevalent social institutions and key lessons from Kenya, Zimbabwe and South Africa, a typology for evaluating important elements of the land reform process in South Africa is developed and discussed. Additionally, a review of global data collected on average sizes of farms in different regions of the world is provided as evidence to support propositions of what would constitute efficient farmland size ranges for small to medium commercial farms in South Africa. Results and conclusion: A proposition is made on how to use the typology to guide policy and research interventions to reduce failures

    Khinkis, Mark J.; Kozlov, Aleksandr P.

    2017-10-31

    A radiant, non-catalytic recuperative reformer has a flue gas flow path for conducting hot exhaust gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is positioned adjacent to the flue gas flow path to permit heat transfer from the hot exhaust gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, a portion of the reforming mixture flow path is positioned outside of flue gas flow path for a relatively large residence time.

    2012-07-01

    The present thesis deals with the topic of the complete fluid dynamic modelling of the key components of a fuel processing system and based on it the development of the next generation reactors. Fuel cell auxilliary power units enable an energy efficient power generation for mobile applications with higher on-board power consumption. Enabling the operation of the fuel cell with the available middle-destillate on-board, the fuel is transformed to an hydrogen-rich gas in a fuel processing system consisting of the key components autothermal reformer, water-shift reactor and catalytic burner. The modules of the fuel processing system are thereby integrated within the reactors to obtain a lightweighted and compact overall system. The complete numerical description of theses systems are based on chemical-reaction models, vaporization models of fuel and water in the integrated reactant treatment and as well on models for the integrated heat-exchanger. The strong interaction between the single reactor zones require therefore modelling of the key components as an overall reactor system. The methodology of the present thesis is based on a tight integration of CFD simulations with experimental analysis and the construction of the reactors. The results of carried out prototype testings, post-mortem-analysis and laboratory experiments are taken as basis for the CFD modelling and the reactor construction. As numerical tool for fluid dynamic modelling the CFD software FLUENT was used. In the context of this thesis the CFD modelling library was extended with the purpose of the complete description of key components in the CFD overall model. In these CFD overall models the thermal interactions between the reactor zones as well as the influence of the pulsating fuel injection and the chemical reactions are taken into account. For this purpose a similarity theoretical CFD modell of the pulsating fuel injection was generated based on results from prototype testings and high

    In this paper, a new design methodology and process is proposed for small scale pure hydrogen production capable of serving energy markets ranging from distributed generation to vehicular refuelling. The system was designed for producing 7 Nm 3 /hr pure hydrogen (purity of ≤ 1 ppm CO dry), yielding 10 kWe net power from a fuel cell system with an overall parasitic power loss ≤ 10 %. The discussion of this process includes a detailed description of the design methodology and operational results of the catalytic converter, the hydrogen purification system and the fuel cell system. This paper will discuss the design methodology of the overall system, as well as the specific design of the catalytic converter, the catalysts used within, and the hydrogen purification system. It will also report the system performance including gas purity, recovery rate, overall hydrogen production efficiencies, and electrical efficiencies during fuel cell operation. (authors)

    Directory of Open Access Journals (Sweden)

    Dragoş Negrescu

    2008-04-01

    Full Text Available The EU budget is the financial tool supporting European integration. The way it has developed over decades, both as concerns revenues and expenditure, superposed to a complex decision-making process, where member states retain veto rights in crucial respects, means that it currently displays a significant inertia, while its size and structure are not the most appropriate for endowing the Union with the means allowing it to best react to the present-day challenges. Tensions are also rising between the national interests of individual members and the common interest, which previous attempts to reconcile by way of special treatments granted to some countries are clearly unsustainable, while inducing additional rigidities to the budgetary construction. This obviates the need for a comprehensive reform, which the 2008/2009 budget review that the Commission was mandated to undertake may set in motion. The following paper attempts at taking stock of the most significant problems in need of a solution and to explore the most appropriate ways available for tackling them.

  14. A Matter of Time: Enacting the Exclusion of Onshore Refugee Applicants through the Reform and Acceleration of Refugee Determination Processes

    Full Text Available State-based processes for determining refugee claims are crucial sites of inclusion or exclusion for onshore refugee applicants. This paper argues that cultures of disbelief and exclusion towards onshore refugee applicants are increasingly being enacted indirectly, via procedural reforms to Refugee Status Determination (RSD, which limit the ability of applicants to establish and articulate their claims. Focusing on Australia and Canada, this paper tracks the acceleration and truncation of RSD procedures, which first reflect and then frequently achieve the exclusion of onshore applicants. Two sets of reforms in particular have profoundly limited the terms on which applicants may present their claims. In Canada, this occurred as the result of a major overhaul of RSD that took place in December 2012. In Australia, the policy of ‘enhanced screening’ of applicants achieves the immediate screening-out of certain claims from the Australian determination system. Alongside analysing these reforms as a means of exclusion, this paper argues that the new procedures most disadvantage applicants making claims on the basis of gender-related persecution. Los procesos estatales para resolver las concesiones de asilo son situaciones cruciales para la inclusión o exclusión de los solicitantes de asilo una vez están en el territorio de acogida. Este artículo defiende que cada vez más, se está promulgando indirectamente la cultura de la desconfianza y exclusión hacia los solicitantes de asilo, a través de reformas procesuales de la Determinación del Estatus de Refugiado (DER, lo que limita la capacidad de los solicitantes para establecer y articular sus demandas de asilo. Centrándose en Australia y Canadá, este artículo realiza un seguimiento de la aceleración y el truncamiento de los procedimientos de DER que primero reflejan y después a menudo consiguen la exclusión de los solicitantes en el propio territorio de acogida.

    Hydrogen has a significant future potential as an alternative energy source for the transportation sector as well as in residential homes and offices, H 2 in fuel cell power systems provides an alternative to direct fossil fuel and biomass combustion based technologies and offer the possibility for a significant reduction in greenhouse gas emission based on improved H 2 yield per unit of fossil fuel and biomass, compatibility with renewable energies and motivation to convert to a H 2 -based energy economy. Several practical techniques for H 2 production to service H 2 refuelling stations as well as homes and offices, all of which need to be located at the end of the energy distribution network, include: (1) the carbon dioxide reforming of natural gas; (2) reforming of gasoline; (3) reforming of crude ethanol. Locating the H 2 production at the end of the energy distribution network solves the well-known problems of metal fatigue and high cost of H 2 compression for long distance transportation if H 2 is produced in a large centralized plant. In addition, the ratification of the Kyoto Protocol and the need to reduce emissions of CO 2 to the atmosphere has prompted the capture and utilization of the CO 2 produced from the reforming process. In this research: (1) new efficient catalysts for each reforming process was developed; (2) a new efficient catalyst for our version of the water gas shift reaction to convert carbon monoxide to carbon dioxide was developed; (3) a new membrane separation process for production of high purity, fuel cell-grade H 2 was designed; (4) a numerical model for optimum process design and optimum utilization of resources both at the laboratory and industrial scales was developed; (5) various processes for CO 2 capture were investigated experimentally in order to achieve a net improvement in the absorption process; (6) the utilization of captured CO 2 for enhanced oil recovery and/or storage in an aging oil field were investigated; (7

    From 2007 on, the World Health Organisation (WHO) has been revising its diagnostic manual, the International Statistical Classification of Diseases and Related Health Problems (ICD), with approval of ICD-11 due in 2018. The ICD revision has prompted debates on diagnostic classifications related to gender diversity and gender development processes, and specifically on the 'Gender incongruence of childhood' (GIC) code. These debates have taken place at a time an emergent trans depathologisation movement is becoming increasingly international, and regional and international human rights bodies are recognising gender identity as a source of discrimination. With reference to the history of diagnostic classification of gender diversity in childhood, this paper conducts a literature review of academic, activist and institutional documents related to the current discussion on the merits of retaining or abandoning the GIC code. Within this broader discussion, the paper reviews in more detail recent publications arguing for the abandonment of this diagnostic code drawing upon clinical, bioethical and human rights perspectives. The review indicates that gender diverse children engaged in exploring their gender identity and expression do not benefit from diagnosis. Instead they benefit from support from their families, their schools and from society more broadly.

    Boaro, M.; Modafferi, V.; Pappacena, A.; Llorca, J.; Baglio, V.; Frusteri, F.; Frontera, P.; Trovarelli, A.; Antonucci, P. L.

    Steam and autothermal reforming of propane over Ni-Rh/GDC catalysts prepared by coprecipitation and by Pechini method were investigated in the temperature range 873-1073 K. The weight ratio for Ni, Rh and Ce 0.8Gd 0.2O 2 (45:5:50) and the operating temperatures were chosen in order to gain propaedeutical information on fuel reactivity under typical intermediate solid oxide fuel cell (IT-SOFC) operating conditions. The Pechini synthesis allows to obtain catalysts with lower surface area, smaller nickel crystallites and a bimodal distribution of rhodium in comparison to the coprecipitation method. Despite the different methods of synthesis lead to catalysts with different morphological and structural properties, the activity of catalysts is quite similar. At reaction temperature higher than 973 K, under both steam reforming (SR) and autothermal reforming (ATR), the catalysts show high propane conversion and syngas (H 2 + CO) productivity. Deactivation of catalysts was observed at 873 and 973 K under SR conditions due to coke formation. In ATR, coke formation was almost completely depressed and the catalysts resulted to be very stable even at low reaction temperature (873 K). In SR coke formation occurs with higher rate on the catalyst having higher Ni dispersion, probably since propane cracking reaction is the pre-eminent phenomenon in promoting coke formation.

    Palladium-based catalytic membrane reactors (CMRs) effectively remove H₂ to induce higher conversions in methane steam reforming (MSR) and water-gas-shift reactions (WGS). Within such a context, this work evaluates the technical performance of a novel CMR, which utilizes two catalysts in series, rather than one. In the process system under consideration, the first catalyst, confined within the shell side of the reactor, reforms methane with water yielding H₂, CO and CO₂. After reforming is completed, a second catalyst, positioned in series, reacts with CO and water through the WGS reaction yielding pure H₂O, CO₂ and H₂. A tubular composite asymmetric Pd/Au/Pd membrane is situated throughout the reactor to continuously remove the produced H₂ and induce higher methane and CO conversions while yielding ultrapure H₂ and compressed CO₂ ready for dehydration. Experimental results involving (i) a conventional packed bed reactor packed (PBR) for MSR, (ii) a PBR with five layers of two catalysts in series and (iii) a CMR with two layers of two catalysts in series are comparatively assessed and thoroughly characterized. Furthermore, a comprehensive 2D computational fluid dynamics (CFD) model was developed to explore further the features of the proposed configuration. The reaction was studied at different process intensification-relevant conditions, such as space velocities, temperatures, pressures and initial feed gas composition. Finally, it is demonstrated that the above CMR module, which was operated for 600 h, displays quite high H₂ permeance and purity, high CH₄ conversion levels and reduced CO yields.

    2017-12-01

    Based on the principle of Gibbs free energy minimization, the thermodynamic analysis on the CO2 conversion processes of dry reforming of methane for H2 and CO2 hydrogenation to dimethyl ether was carried out. The composition of the reaction system was determined on the basis of reaction mechanism. The effects of reaction temperature, pressure and raw material composition on the equilibrium conversion and the selectivity of products were analyzed. The results show that high temperature, low pressure, CO2/CH4 molar ratio of 1.0-1.5 and appropriate amount of oxygen are beneficial to the dry reforming of methane. For CO2 hydrogenation to dimethyl ether, low temperature, high pressure, the appropriate H2/CO2 and the proper CO addition in feed are favorable. The calculated results are compared with the relevant studies, indicating that industrial catalytic technology needs further improvement.

    1988-01-01

    The HTR is the only reactor system which can provide process heat in a wide temperature range up to 950 0 C. The HTR module is designed as an unsophisticated, safe and universal heat source with a large field of applications. The following applications have been considered: the steam reforming of natural gas and coal conversion processes for the production of methanol, hydrogen and SNG. They are investigated in many different modifications and nuclear and autothermal processes are compared. Other applications of nuclear process heat in the chemical and petrochemical industry seem to be appropriate and promising, but could not be analysed because of lack of data. The economic results show that for today's coal and gas processing the HTR can only compete against conventional conversion processes for specific premises. Especially, those processses in which valuable fossil fuels such as natural gas are substituted by nuclear process heat promise an economic bebefit. Looking to the market of the year 2030 and the need for process heat in the chemical and steel industries (including the demand for synthesis gas), cement and refinery industries, for the production of aluminium oxide and for tertiary oil recovery, a total theoretical market in the Federal Republic of Germany of up to 60 HTR-2 module plants is estimated

    2002-07-01

    A life cycle inventory analysis has been conducted to assess the environmental load, specifically CO{sub 2} (fossil) emissions and global warming potential (GWP), associated to the production of hydrogen by the steam reforming of hydrocarbon feedstocks (methane and naphtha) and vegetable oils (rapeseed oil, soybean oil and palm oil). Results show that the GWPs associated with the production of hydrogen by steam reforming in a 100 years time frame are 9.71 and 9.46 kg CO{sub 2}-equivalent/kg H{sub 2} for natural gas and naphtha, respectively. For vegetable oils, the GWP decreases to 6.42 kg CO{sub 2}-equivalent/kg H{sub 2} for rapeseed oil, 4.32 for palm oil and 3.30 for soybean oil. A dominance analysis determined that the part of the process that has the largest effect on the GWP is the steam reforming reaction itself for the fossil fuel-based systems, which accounts for 56.7% and 74% of the total GWP for natural gas and naphtha, respectively. This contribution is zero for vegetable oil-based systems, for which harvesting and oil production are the main sources of CO{sub 2}-eq emissions.(author)

    In large systems, such as health care, reforms are underway constantly. The article presents a definition of health care reform and factors that influence its success. The factors being discussed range from knowledgeable personnel, the role of involvement of international experts and all stakeholders in the country, the importance of electoral mandate and governmental support, leadership and clear and transparent communication. The goals set need to be clear, and it is helpful to have good data and analytical support in the process. Despite all debates and experiences, it is impossible to clearly define the best approach to tackle health care reform due to a different configuration of governance structure, political will and state of the economy in a country.

    2014-08-01

    Full Text Available In this study, the performance of several differently treated natural zeolites in a sequential pyrolysis and catalytic reforming of plastic materials i.e. polypropylene (PP and polystyrene (PS were investigated. The experiments were carried out on two stage reactor using semi-batch system. The samples were degraded at 500°C in the pyrolysis reactor and then reformed at 450°C in the catalytic reformer. The results show that the mordenite-type natural zeolites could be used as efficient catalysts for the conversion of PP and PS into liquid and gaseous fuel. The treatment of natural zeolites in HCl solution showed an increase of the surface area and the Si/Al ratio while nickel impregnation increased the activity of catalyst. As a result, liquid product was reduced while gaseous product was increased. For PP, the fraction of gasoline (C5-C12 increased in the presence of catalysts. Natural zeolite catalysts could also be used to decrease the heavy oil fraction (>C20. The gaseous products were found that propene was dominated in all conditions. For PS, propane and propene were the main components of gases in the presence of nickel impregnated natural zeolite catalyst. Propene was dominated in pyrolysis over natural zeolite catalyst. The high quality of gaseous product can be used as a fuel either for driving gas engines or for dual-fuel diesel engine.

The reaction was studied at different process intensification-relevant conditions, such as space velocities, temperatures, pressures and initial feed gas composition. Finally, it is demonstrated that the above CMR module, which was operated for 600 h, displays quite high H2 permeance and purity, high CH4 conversion levels and reduced CO yields.

    Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form synthesis gas (syngas). Closed-loop reforming/methanation systems can be used for storage and transport of process heat and for short-term storage for peaking power generation. Open-loop systems can be used for direct fuel production; for production of syngas feedstock for further processing to specialty chemicals and plastics and bulk ammonia, hydrogen, and liquid fuels; and directly for industrial processes such as iron ore reduction. In addition, reforming of organic chemical wastes and hazardous materials can be accomplished using the high-efficiency destruction capabilities of steam reforming. To help identify the most promising areas for future development of this technology, we discuss in this paper the economics and market potential of these applications.

    Portable fuel cells are an enabling technology for high efficiency and ultra-high density distributed power generation, which is essential for many terrestrial and aerospace applications. A key element of fuel cell power sources is the fuel processor, which should have the capability to efficiently reform liquid fuels and produce high purity hydrogen that is consumed by the fuel cells. To this end, we are reporting on the development of two novel MEMS hydrogen generators with improved functionality achieved through an innovative process organization and system integration approach that exploits the advantages of transport and catalysis on the micro/nano scale. One fuel processor design utilizes transient, reverse-flow operation of an autothermal MEMS microreactor with an intimately integrated, micromachined ultrasonic fuel atomizer and a Pd/Ag membrane for in situ hydrogen separation from the product stream. The other design features a simpler, more compact planar structure with the atomized fuel ejected directly onto the catalyst layer, which is coupled to an integrated hydrogen selective membrane.

    The U.S. Department of Energy National Energy Technology Laboratory funded this research collaboration effort between NextEnergy and the University of Michigan, who successfully designed, built, and tested a reformer system, which produced highquality syngas for use in SOFC and other applications, and a novel reactor system, which allowed for facile illumination of photocatalysts. Carbon and raw biomass gasification, sulfur tolerance of non-Platinum Group Metals (PGM) based (Ni/CeZrO2) reforming catalysts, photocatalysis reactions based on TiO2, and mild pyrolysis of biomass in ionic liquids (ILs) were investigated at low and medium temperatures (primarily 450 to 850 C) in an attempt to retain some structural value of the starting biomass. Despite a wide range of processes and feedstock composition, a literature survey showed that, gasifier products had narrow variation in composition, a restriction used to develop operating schemes for syngas cleanup. Three distinct reaction conditions were investigated: equilibrium, autothermal reforming of hydrocarbons, and the addition of O2 and steam to match the final (C/H/O) composition. Initial results showed rapid and significant deactivation of Ni/CeZrO2 catalysts upon introduction of thiophene, but both stable and unstable performance in the presence of sulfur were obtained. The key linkage appeared to be the hydrodesulfurization activity of the Ni reforming catalysts. For feed stoichiometries where high H2 production was thermodynamically favored, stable, albeit lower, H2 and CO production were obtained; but lower thermodynamic H2 concentrations resulted in continued catalyst deactivation and eventual poisoning. High H2 levels resulted in thiophene converting to H2S and S surface desorption, leading to stable performance; low H2 levels resulted in unconverted S and loss in H2 and CO production, as well as loss in thiophene conversion. Bimetallic catalysts did not outperform Ni-only catalysts, and small Ni particles were

    A novel concept for diesel fuel processing utilizing H2O2 is suggested to obtain the high-purity H2 required for air-independent propulsion using polymer electrolyte membrane fuel cells for use in submarines and unmanned underwater vehicles. The core components include 1) a diesel-H2O2 autothermal reforming (ATR) reactor to produce H2-rich gas, 2) a water-gas shift (WGS) reactor to convert CO to H2, and 3) a H2 separation membrane to separate only high-purity H2. Diesel and H2O2 can easily be pressurized as they are liquids. The application of the H2 separation membrane without a compressor in the middle of the process is thus advantageous. In this paper, the characteristics of pressurized ATR and WGS reactions are investigated according to the operating conditions. In both reactors, the methanation reaction is enhanced as the pressure increases. Then, permeation experiments with a H2 separation membrane are performed while varying the temperature, pressure difference, and inlet gas composition. In particular, approximately 90% of the H2 is recovered when the steam-separated rear gas of the WGS reactor is used in the H2 separation membrane. Finally, based on the experimental results, design points are suggested for maximizing the efficiency of the diesel-H2O2 fuel processor.

In this project, an active, stable and selective catalyst was developed for the reactions of interest and its production was scaled up to kg scale (TRL5 (TRL: Technology Readiness Level. Simultaneously, new membranes for gas separation were developed. In particular, dense supported thin palladium-based membranes were developed for hydrogen separation from reactive mixtures. These membranes were successfully scaled up to TRL4 and used in lab-scale reactors for fluidized bed steam methane reforming (SMR and autothermal reforming (ATR and in a prototype reactor for ATR. Suitable sealing techniques able to integrate the different membranes in lab-scale and prototype reactors were also developed. The project also addressed the design and optimization of the subcomponents (BoP for the integration of the membrane reformer to the fuel cell system.

    The policy reform literature is primarily concerned with the construction of reforms that yield welfare gains. By contrast, this paper’s contribution is to develop a theoretical concept for which the focus is upon the sizes of welfare gains accruing from policy reforms rather than upon their signs....... In undertaking this task, and by focusing on tariff reforms, we introduce the concept of a steepest ascent policy reform, which is a locally optimal reform in the sense that it achieves the highest marginal gain in utility of any feasible local reform. We argue that this reform presents itself as a natural...... benchmark for the evaluation of the welfare effectiveness of other popular tariff reforms such as the proportional tariff reduction and the concertina rules, since it provides the maximal welfare gain of all possible local reforms. We derive properties of the steepest ascent tariff reform, construct...

  5. The rise and fall of French Ecological Tax Reform: social acceptability versus political feasibility in the energy tax implementation process

    Deroubaix, Jose-Frederic; Leveque, Francois

    2006-01-01

    The French government has a 10-year history of negotiations with industry, resulting in voluntary agreements on energy consumption. When implemented, these voluntary agreements produced very few results in terms of global reduction of greenhouse emissions (Politiques et Management Public 11(4) (1993) 47), hence the idea of an energy tax became increasingly attractive for many French decision-makers. Ecological/Environmental Tax Reform (ETR) should have been one of the major political decisions and successes of the past leftwing coalition government. Instead it became one of its major failures as the Constitutional Court decided to terminate the energy tax project in December 2000. Through insights gleaned from focus groups and interviews with business-people and decision-makers, an attempt is made to understand the failure of the energy tax project. Firstly, decision-makers lacked crucial information about public and business opinions and secondly, there were conflicts between the relevant administrations. The fuel revolts of 2000 ended any hope of resolving the conflicts and implementing ETR, which was ultimately found unconstitutional. This paper examines the political controversies raised by the ETR project and the reasons for its eventual collapse, in the hope of contributing new understanding to the body of knowledge on the political difficulties of introducing environmental policy instruments

    Aqueous phase reforming is useful for processing oxygenated hydrocarbons to hydrogen and other more useful products. Current processing is hampered by the fact that oxide based catalysts are not stable under high temperature hydrothermal conditions. Silica in the form of structured MCM-41 is thermally a more stable support for Co and Ni than conventional high surface area amorphous silica but hydrothermal stability is not demonstrated. Carbon nanotube supports, in contrast, are highly stable under hydrothermal reaction conditions. In this project we show that carbon nanotubes are stable high activity/selectivity supports for the conversion of ethylene glycol to hydrogen.

  7. Environmental consequences of electricity sector reforms

    International Nuclear Information System (INIS)

    Wohlgemuth, N.

    1999-01-01

    Worldwide, the electricity industry is in the process of undergoing fundamental transitions. The reform process typically involves one or more of the following changes: commercialisation, privatisation, unbundling/restructuring and introduction of competition. The environmental impacts of these changes pull in different directions. There is concern that restructured electricity markets may not always incorporate adequately the environmental impacts of electricity resource development and consumption decisions. However, the electricity sector reform process also offers an opportunity to promote positive environmental changes: because the sector is already in flux, it may be easier to address environmental issues. The paper gives an overview of power sector reform in six countries where reforms have already been implemented, and concludes that reform measures will have to be accompanied by competitively neutral regulations in order to stimulate investment in environmentally sound technologies, including renewable and energy efficient technologies.

    The paper presents a process of cellulose thermal degradation with bio-hydrogen generation and zinc nanostructures synthesis. Production of zinc nanowires and zinc nanoflowers was performed by a novel processes based on cellulose pyrolysis, volatiles reforming and direct reduction of ZnO. The bio-hydrogen generated in situ promoted the ZnO reduction with Zn nanostructures formation by vapor-solid (VS) route. The cellulose and cellulose/ZnO samples were characterized by thermal analyses (TG/DTG/DTA) and the gases evolved were analyzed by FTIR spectroscopy (TG/FTIR). The hydrogen was detected by TPR (Temperature Programmed Reaction) tests. The results showed that in the presence of ZnO the cellulose thermal degradation produced larger amounts of H 2 when compared to pure cellulose. The process was also carried out in a tubular furnace with N 2 atmosphere, at temperatures up to 900 o C, and different heating rates. The nanostructures growth was catalyst-free, without pressure reduction, at temperatures lower than those required in the carbothermal reduction of ZnO with fossil carbon. The nanostructures were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS) and transmission electron microscopy (TEM). The optical properties were investigated by photoluminescence (PL). One mechanism was presented in an attempt to explain the synthesis of zinc nanostructures that are crystalline, were obtained without significant re-oxidation and whose morphologies are dependent on the heating rates of the process. This route presents a potential use as an industrial process taking into account the simple operational conditions, the low costs of cellulose and the importance of bio-hydrogen and nanostructured zinc.

    China experienced both economic and epistemological transitions within the past few decades, greatly increasing demand for accessible and affordable health care. These shifts put significant pressure on the existing outdated, highly centralized bureaucratic system. Adjusting to growing demands, the government has pursued a new round of health reforms since the late 2000s; the main goals are to reform health care financing, essential drug policies, and public hospitals. Health care financing reform led to universal basic medical insurance, whereas the public hospital reform required more complex measures ranging from changes in regulatory, operational, and service delivery settings to personnel management. This article reviews these major policy changes and the literature-based evidence of the effects of reforms on cost, access, and quality of care. It then highlights the outlook for future reforms. We argue that a better understanding of the unintended consequences of reform policies and of how practitioners' and patients' interests can be better aligned is essential for reforms to succeed.

    Full Text Available Ethics review is a pre-requisite to conducting research involving humans in Canada, and indeed in most international jurisdictions. The Tri-Council Policy Statement on Ethical Conduct for Research Involving Humans (TCPS2 serves as the national policy framework for research ethics review in Canada, and outlines three potential oversight models: independent, delegated and reciprocal. While the independent model preserves institutional oversight of research, it contributes to a duplicative system that can unduly delay research and impose barriers to research collaboration. This analysis centres on a 2015 reform to the policy model of research ethics review for collaborative, multi-site studies in the province of Québec. Informal interviews with key informants supplemented a document analysis of provincial research ethics policies using the comparative framework proposed by Lavis and colleagues. Consolidating bureaucratic structures and preserving locally-relevant review studies that span multiple sites remain among the most pressing challenges to transitioning from an independent model, and could provide reference for other provinces that have, or are currently in the process of such a transition.

    An environmental tax reform is seen by many as a possible solution to some crucial problems of modern society - pollution, excessive resource consumption and unemployment. Changes in the system of taxation are here seen as a long term process, one that must cheapen the costs of labour and make the costs of resource use more expensive - a process which can also create major changes in our society as to conceptions of quality, work, consumption etc. The conference presented proposals for an ecological tax and duty system that would contribute to: Changing technology so that it becomes more resource and energy effective. Changing the economic mechanisms so that resource consumption and pollution become more expensive while human resources become cheaper. Changing personal life styles and values so that material consumption becomes less decisive for our choices and priorities. An environmental tax reform is neither without problems nor painless. An economy and an industrial sector based on increasing consumption of energy and raw materials will, in the long run, lead to drawbacks that far outweigh those that are connected with an economic re-orientation whose driving force is another conception of nature.

An energy requirement analysis of steam reforming to dry reforming with intermediate steps of steam reduction and equivalent CO2 addition to the feed fuel for syngas generation has been done to identify condition for optimum process operation. Thermodynamic equilibrium data for combined reforming was generated for temperature range of 400–1000°C at 1 bar pressure and combined oxidant (CO2 + H2O stream to propane (fuel ratio of 3, 6, and 9 by employing the Gibbs free energy minimization algorithm of HSC Chemistry software 5.1. Total energy requirement including preheating and reaction enthalpy calculations were done using the equilibrium product composition. Carbon and methane formation was significantly reduced in combined reforming than pure dry reforming, while the energy requirements were lower than pure steam reforming. Temperatures of minimum energy requirement were found in the data analysis of combined reforming which were optimum for the process.

Analysis of land reform, which started in 1990, shows what actions and what logic led the land sector in the state in which it was at the finish line of the quarter-century reform marathon. The reform process was not linear, it highlighted the steps differing objectives and strategies to achieve them. Land reform is presented as a struggle of different political forces, which were reflected in the redistribution of functions between agencies in lobbying for appointment to senior positions promoted various commands. The authors conclude about the gradual displacement of state regulation of land relations, the deliberate destruction of the land management as a basis for the development of land resources.

  1. Modern Processes of Hydrocarbon Migration and Re-Formation of Oil and Gas Fields (Based on the Results of Monitoring and Geochemical Studies)

    Special geochemical studies of oils allowed to allocate a movable migration component of oils in the industrial oil deposits. In the field the migration component of oils varies in different parts of the field. The largest percentage of the light migration component (gas condensate of the oil) was detected in the central part of the Kama-Kinel troughs system. Monitoring of the composition of water, oil and gas (condensate light oil component) in the sedimentary cover and ni crystalline basement led to the conclusion of modern migration of hydrocarbons in sedimentary cover. This proves the existence of the modern processes of formation and reformation of oil and gas fields. This presentation is dedicated to the problem of definition of geochemical criteria of selection of hydrocarbons deposit reformation zone in the sample wells of Minibaevskaya area of Romashkinskoye field. While carrying out this work we examined 11 samples of oil from the Upper Devonian Pashiysky horizon. Four oil samples were collected from wells reckoned among the "anomalous" zones that were marked out according to the results of geophysical, oil field and geological research. Geochemical studies of oils were conducted in the laboratory of geochemistry of the Kazan (Volga-region) Federal University. The wells where the signs of hydrocarbons influx from the deep zones of the crust were recorded are considered to be "anomalous". A number of scientists connect this fact to the hypothesis about periodic influx of deep hydrocarbons to the oil deposits of Romashkinskoye field. Other researchers believe that the source rocks of the adjacent valleys sedimentary cover generate gases when entering the main zone of gas formation, which then migrate up the section and passing through the previously formed deposits of oil, change and "lighten" their composition. Regardless of the point of view on the source of the hydrocarbons, the study of the process of deposits refilling with light hydrocarbons is an

    Kelly Oliver

    2014-12-01

    Full Text Available In my brief remarks, I consider what it means to return and rebind—that is to say, the significance of the re for Kristeva’s thought.  Kristeva does not just talk about binding or birth, or unbinding or death, but rather rebinding and rebirth, suggesting that it is a retrospective return rather than an original moment that is crucial.  The most significant moment, then, is not the moment of imaginary plenitude, nor the moment of originary loss, but rather the moment of rebirth that comes through rebinding after the loss of plenitude.  Indeed, Kristeva’s insistence on re-turning suggests that there is no originary moment of plenitude nor of castration or loss, but rather a constant movement of compensation for a recurrent loss.  By emphasizing rebinding and rebirth, she underscores not the loss as cutting wound but rather the healing power of signification, always already inherent within loss.  The flip-side of separation is reattachment.  And rather than just focus on the separation or cut, Kristeva looks to that which allows us to rebind and reattach in order to create relations that sustain us.  Both unbinding and binding are necessary for rebinding.  Thus, by focusing on rebinding, Kristeva insists on the process of unbinding and binding, and the oscillation between them.

    The political dimension of the health reform is a fundamental aspect that not only influences the project's feasibility, but also its form and content. Therefore the study of the political aspects involved in the health reform process is essential to determine the political feasibility of the reform. Based on the case studies of Colombia and Mexico, this study concentrates on the State's capability to promote health reform projects successfully. It specifically focuses on those elements that seek to improve the political feasibility of formulating, legislating and implementing reform proposals. The relevant variables under study are: the institutional context in which the reform initiatives develop; the political dynamic of the reform process; and the characteristics and strategies of the teams in charge of leading the reforms (change teams). The similarities in the political strategies used by the teams in charge of the health reform, and those of similar technocratic teams in charge of economic reform, stand out as one the study's main findings. It is argued that, although these strategies were effective in bringing about the creation of new actors in the health sector such as private organizations for the financing and provision of health services, they did not have the same impact on the transformation of the old actors the health ministries and the social security institutes, therefore considerably limiting the scope of the reforms.

    2010-01-01

    In early 1990 the power sector in India required an initial set of reforms due to the scarcity of financial resources and its deteriorating technical and commercial efficiency. The Indian power sector is now going through a second stage of reforms in which restructuring of electric supply utilities has taken place. The Maharashtra State Electricity Board (MSEB) initiated reforms in 2005 by dividing the state electricity board into four separate companies. In this paper, the situations that led to the reform of the MSEB and the scope of the work required for an action plan initiated by the state electricity distribution company in the context of the proposed Key Performance Index are discussed. The post-reform status of the distribution company is analyzed with selected key parameters. The study also analyzes the electricity supply model implemented and the effect of a multi-year tariff plan as one of the key milestones of the tariff structure. The various new projects implemented by the distribution company to improve consumer services and the reform experiences of the other states are discussed, along with the future scope of the present reform process.

    1997-01-01

    Methane forming reactions using either steam or CO 2 have been known to industry for a long time. These endothermic reactions require the investment of a relatively large amount of energy. German researchers, in the 1970's, conceived and developed the idea to use this reaction and the reverse methanation reaction in a closed loop for the transportation and distribution of nuclear heat. The idea was also adopted for use with solar energy as a heat source. Utilizing solar energy as the heat source, the Weismann Institute of Science has fabricated, installed and operated a complete loop capable of the conversion and transportation of over 400 kW of heat. This system can be operated with a wide range of CO 2 /H 2 O/CH 4 feed mixtures. Steam reforming is the common reforming reaction in the ''open loop'' mode for the purpose of synthesis gas production. This is accomplished with a large excess of steam on a nickel catalyst. However, it has only recently been recognized that there is also a substantial market for CO 2 reforming. The CO 2 /CH 4 mixture in various proportions exists in many places and has, so far, not been used efficiently. The sources for this mixture are biogas produced in anaerobic digestion processes and gas resources such as the NATUNA gas field in Indonesia, and many others. Therefore, the system of CO 2 /CH 4 deserves more attention. Commercial catalysts used for steam reforming based on nickel are not suitable for this system. Therefore, other catalysts based on Rhodium and Ruthenium have been developed and some performance data is presented in this paper. Also presented is a conceptual schematic layout of a CO 2 reforming plant and matching methanator. A computer code for a detailed design of the entire loop in a commercial size system has been prepared where optimized operational conditions as well as equipment parameters can be determined.

    Since about 1990, many developing and transition countries have undertaken market-oriented reforms in their electric power sectors. Despite the widespread adoption of a standard policy model, reform processes and outcomes have often failed to meet expectations. Drawing on an extensive literature review and case studies in Asia, Africa, Latin America, and Eastern Europe, this paper describes common features of non-OECD electricity reform and reappraises reform policies and underlying assumptions. Comparison with the sector-focused policy goals of deregulation in OECD countries highlights the importance of national fiscal crises, macroeconomic reforms, and persuasion by multilateral lenders in shaping non-OECD reforms. It also makes clear reform's dependence on attracting foreign capital, and consequent vulnerability to volatile international financial conditions. Case studies of Bolivia, Ghana, India, Poland, and Thailand illustrate reform's diverse pathways and problems in different settings. A broad range of non-OECD reform experiences indicates that disappointing results have often resulted from a narrow focus on finance and cost recovery, inflexibly applied. The paper concludes that improving reform will require emphasizing a broader set of objectives, including service provision, public benefits, effective regulation, and social/political legitimacy. Above all, reforms must be based on realistic assessments of national needs and capabilities. (author)

    Furman, Jason

    2008-01-01

    Tax incentives for employer-sponsored insurance and other medical spending cost about $200 billion annually and have pervasive effects on coverage and costs. This paper surveys a range of proposals to reform health care, either by adding new tax incentives or by limiting or replacing the existing tax incentives. Replacing the current tax preference for insurance with an income-related, refundable tax credit has the potential to expand coverage and reduce inefficient spending at no net federal cost. But such an approach by itself would entail substantial risks, so complementary reforms to the insurance market are essential to ensure success.

  2. Steam Methane Reformation Testing for Air-Independent Solid Oxide Fuel Cell Systems

    2015-01-01

    Recently, NASA has been looking into utilizing landers that can be propelled by LOX-CH (sub 4), to be used for long duration missions. Using landers that utilize such propellants, also provides the opportunity to use solid oxide fuel cells as a power option, especially since they are able to process methane into a reactant through fuel reformation. One type of reformation, called steam methane reformation, is a process to reform methane into a hydrogen-rich product by reacting methane and steam (fuel cell exhaust) over a catalyst. A steam methane reformation system could potentially use the fuel cell's own exhaust to create a reactant stream that is hydrogen-rich, and requires less internal reforming of the incoming methane. Also, steam reformation may hold some advantages over other types of reforming, such as partial oxidation (PROX) reformation. Steam reformation does not require oxygen, while up to 25 percent can be lost in PROX reformation due to unusable CO (sub 2) reformation. NASA's Johnson Space Center has conducted various phases of steam methane reformation testing, as a viable solution for in-space reformation. This has included using two different types of catalysts, developing a custom reformer, and optimizing the test system to find the optimal performance parameters and operating conditions.

  3. Reforming Educational Reform: A Democratic Perspective

    Green, J.

    2005-05-01

    This essay examines the status of educational reform in the United States as represented by the current Bush administration's program titled "No Child Left Behind" (NCLB). Employing the techniques of critical theory and logical analysis, contemporary reform efforts are compared with other, more progressive, educational reform movements in an effort to gain perspective and conceptual "traction" as it were, in differentiating such movements. Criteria are established for the assessment and evaluation of reform movements. These are employed in judging the efficacy of NCLB's aim, content, and methods, as well as the results of its program following four years of implementation. The merits of the centrality of standardized testing, pre-ordained curricular content, and exclusively didactic teaching methodologies are criticized, along with the extra-school societal forces which ordain these and determine their prominence in the NCLB program. The essentialism adopted by NCLB is, moreover, evaluated in the light of pragmatic, phenomenological, and postmodern educational theory. Arguing that the school is always and inevitably an instrument of societal forces, interests, and groups, it is contended that these not only be acknowledged, but that avenues be formalized for a thorough going and continuous educational "conversation," to borrow Rorty's term, for an amicable resolution of the issues of education's aim(s), content, and methods.

  4. Reforming Romanian energy policy

    International Nuclear Information System (INIS)

    Perkins, S.

    1993-01-01

    Success in reforming energy sector depends on the implementation of the programme of economic reform agreed in February 1993. The difficulty of the negotiations between the International Monetary Fund and the Romanian government reflects the wider difficulties faced by the economy as a whole. They can be blamed in part on the legacy of uneconomic and inflexible industrial development and in part on opposition from interest groups which stand to lose from reform. Nonetheless, in spite of hesitant approach, the government does appear committed to the economic reform necessary to establish a market-oriented economy. But as the danger of a financial crisis engendered by the inadequately supported short-term borrowing of foreign exchange becomes urgent, the question is whether economic reform can be now implemented fast enough to protect economic enterprises and saving from a debt crisis. The scope for further delay in implementing the 1993 economic reform programme is fast disappearing. Procrastination should not be allowed to threaten the success of the reforms achieved in the energy and other sectors of the economy. 8 refs., 2 figs

Busca-se analisar a cidadania como instrumento e finalidade do processo de trabalho das equipes de seis instituições de atenção extra-hospitalar em saúde mental, da rede pública de Cuiabá (MT, no segundo semestre de 2001. Utiliza-se a dialética marxista como referencial teórico-metodológico. Apesar de se afirmar os direitos de cidadãos para os "pacientes", agora denominados "usuários" dos serviços, o paradoxo entre o conceito de cidadania e "doente mental" não foi problematizado e, portanto, não resulta em atitudes terapêuticas que possibilitem ou assegurem a participação cidadã de profissionais e usuários. A cidadania corresponde a uma abstração, excluída da esfera de trabalho e/ou tratamento. No trabalho alienado não se explicita a situação contraditória na qual os trabalhadores são agentes que operam saberes e práticas tradicionalmente excludentes e, simultaneamente, necessitam superar esse papel e produzir práticas de atenção psicossocial que respeitem o cidadão portador de transtorno mental.Within the Brazilian context, starting at the end of the 20th century, the psychiatric reform presented the necessity to rescue the rights of citizenship for the mentally ill.

    2007-07-01

    India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

    Full Text Available Since the reformation and democratization movement in 1998, Indonesians have faced a chronic corruption problem. At the beginning of reformation era in 1998 to fight against corruption, the Indonesian government reforms the organization structure of the Indonesia Police to be an independent body separated from the Military organization. The police reforms begun in 1999 and got legal foundation with Act No. 2/2002. However, since fourteen years, the level of police reform has not yet succeed because of low community satisfaction on police service and the intense conflicts always occur whenever ACA investigates the case of corruptions conducted by police leaders. Three conflicts between police institution and ACA have taken placed. By using institutionalism approach, this research focus on the reform in police themselves are major actors on how reforms are organized and managed. This study is interpretative in nature gained only through social constructions such as language, consciousness, shared meanings, documents, tools, and other artefacts’. This finding revealed that this unsuccessful institutionalization process took place in a context of the main task of police for communicty service. Second, the study has demonstrated that three concepts from institutional theory as aforementioned provided vocabularies and insights to explain the phenomenon under study.

  14. Formal Housing Sector Reform in Neoliberal Nigeria

    Directory of Open Access Journals (Sweden)

    Maren Mallo Daniel

    2016-09-01

    Full Text Available In the past two decades, Nigeria has deployed neoliberal principles in the provision of formal housing. This approach was adopted on the assumption that the implementation of enabling reforms would enhance the role of the private sector and equally promote the development of a formal housing system in Nigeria. This has not occurred; the neoliberal housing approach has brought fewer results than the reform promised. The study therefore aims to explore the agency and actions of Nigerian authorities in response to this neoliberal agenda. To achieve this aim, the following objectives are pursued: The first objective analyses why neoliberalism failed to effectively change the housing market in Nigeria; the second examines the impact of neoliberal restructuring process on housing provision in Nigeria; and the last analyses the success of legislative reform that were carried to support housing provision under Nigeria’s neoliberalism. To achieve these objectives, the paper adopts a documentary method and in accordance with this, a wide range of documentary evidence was collected for a content analysis. The findings of the analysis suggest that economic recession, political instability and changing ideological stances of successive governments affected the consistency of neoliberal reforms. Furthermore, the reforms implemented were seen to be progressive but the events occurred rather slowly, haphazardly and uncoordinated. A time lag is also observed in the reform processes and the sequence of events shows a lack of consideration of the interdependency of legislation and action. This policy review concludes that the neoliberal approach has the potential to improve the delivery of formal housing; however the authorities need to be consistent with the reforms while at the same time aligning legislation and action.

  19. Design of a nuclear steam reforming plant

    International Nuclear Information System (INIS)

    Malherbe, J.

    1980-01-01

    The design of a plant for the steam reforming of methane using a High Temperature Reactor has been studied by CEA in connection with the G.E.G.N. This group of companies (CEA, GAZ DE FRANCE, CHARBONNAGES DE FRANCE, CREUSOT-LOIRE, NOVATOME) is in charge of studying the feasibility of the coal gasification process by using a nuclear reactor. The process is based on the hydrogenation of the coal in liquid phase with hydrogen produced by a methane steam reformer. The reformer plant is fed by a pipe of natural gas or SNG. The produced hydrogen feeds the gasification plant which could not be located on the same site. An intermediate hydrogen storage between the two plants could make the coupling more flexible. The gasification plant does not need a great deal of heat and this heat can be satisfied mostly by internal heat exchanges

  20. High temperature nuclear heat for isothermal reformer

    International Nuclear Information System (INIS)

    Epstein, M.

    2000-01-01

    High temperature nuclear heat can be used to operate a reformer with various feedstock materials. The product synthesis gas can be used not only as a source for hydrogen and as a feedstock for many essential chemical industries, such as ammonia and other products, but also for methanol and synthetic fuels. It can also be burnt directly in a combustion chamber of a gas turbine in an efficient combined cycle and generate electricity. In addition, it can be used as fuel for fuel cells. The reforming reaction is endothermic and the contribution of the nuclear energy to the calorific value of the final product (synthesis gas) is about 25%, compared to the calorific value of the feedstock reactants. If the feedstock is from fossil origin, the nuclear energy contributes to a substantial reduction in CO 2 emission to the atmosphere. The catalytic steam reforming of natural gas is the most common process. However, other feedstock materials, such as biogas, landfill gas and CO 2 -contaminated natural gas, can be reformed as well, either directly or with the addition of steam. The industrial steam reformers are generally fixed bed reactors, and their performance is strongly affected by the heat transfer from the furnace to the catalyst tubes. In top-fired as well as side-fired industrial configurations of steam reformers, the radiation is the main mechanism of heat transfer and convection heat transfer is negligible. The flames and the furnace gas constitute the main sources of the heat. In the nuclear reformers developed primarily in Germany, in connection with the EVA-ADAM project (closed cycle), the nuclear heat is transferred from the nuclear reactor coolant gas by convection, using a heating jacket around the reformer tubes. In this presentation it is proposed that the helium in a secondary loop, used to cool the nuclear reactor, will be employed to evaporate intermediate medium, such as sodium, zinc and aluminum chloride. Then, the vapors of the medium material transfer

    Science.gov (United States)

    Lagowski, J. J.

    1995-09-01

    Since 1991, the National Science Foundation has signed cooperative agreements with 26 states to undertake ambitious and comprehensive initiatives to reform science, mathematics, and technology education. Collectively, those agreements are known as the State Systemic Initiatives (SSI's). Two complimentary programs, The Urban and Rural Systemic Initiatives (USI's and RSI's), address similar reforms in the nation's largest cities and poorest rural areas. The SSI Program departs significantly from past NSF practice in several ways. The funding is for a longer term and is larger in amount, and the NSF is taking a more activist role, seeking to leverage state and private funds and promote the coordination of programs within states. The Initiatives also have a stronger policy orientation than previous NSF programs have had. The NSF strategy is a reflection of the growing and widely held view that meaningful reforms in schools are most likely to be achieved through state initiatives that set clear and ambitious learning goals and standards; align all of the available policy levers in support of reform; stimulate school-level initiatives; and mobilize human and financial resources to support these changes. Two premises underlie systemic reform: (1) all children can meet significantly higher standards if they are asked to do so and given adequate opportunities to master the content, and (2) state and local policy changes can create opportunities by giving schools strong and consistent signals about the changes in practice and performance that are expected. Because this is an enormous investment of Federal resources that is intended to bring about deep, systemic improvement in the nation's ability to teach science and mathematics effectively, the NSF has contracted with a consortium of independent evaluators to conduct a review of the program. The first of the SSI's were funded in 1991, sufficiently long ago to begin to formulate some initial impressions of their impact. Take

  4. Rorty the Reformer?

    Directory of Open Access Journals (Sweden)

    Harvey Cormier

    2008-12-01

    Full Text Available Rorty should be read as a reformer, rather than a revolutionary transformer. While the reformer aims to improve what is already good, the revolutionary transformer seeks to dispense with the merely good in a quest for the absolutely best. For Rorty this choice was a bad choice. In order to make the case that Rorty was a reformer,we explicate Rorty’s views on truth. These views argue that we can obtain consensus about what is worth preserving and improving without reference to either rightness, truth, or objectivity. For after all, there is no way for philosophers to get outside the circle of language within which we debate about what we take to be authoritative and aceptable.

    Full Text Available In this paper the author investigates, from a qualitative perspective, the problems associated with implementing educational innovations. He studies the recent case of the Basic Cycle reform in Uruguay. Based on the concepts of van der Vegt and Vandenberghe (1992, he analyzes the "functions guides" exercised by the director in order to be able to regulate the internal flow of the implementation. The first of these is "conceptual clarity", which has to do with providing the professors with a clear vision of what will take place within the implementation, and with specifying that vision in terms of the professional knowledge and abilities of the faculty as well. The second of these is "directional pressure," which refers to an operational level of the implementation; that is to say, how daily activities mesh with the objectives of the reform. Next, "function of support" refers to the support offered by the director for the management of resources (material, emotional, technical, and administrative resources, so that the resources may then effectively support the work in the center. Finally is "definition of latitude," that is, the degree of educational autonomy that the faculty have with respect to the external objectives of the reform. En este trabajo el autor estudia, desde una perspectiva cualitativa, la problemática de la implementación de innovaciones educativas. Toma por caso la reciente reforma del Ciclo Básico en Uruguay. Con base en los conceptos de van der Vegt y Vandenberghe (1992, analiza las "funciones guía" ejercidas por el director para poder regular el flujo interno de la implementación. La primera de ellas es la "claridad conceptual", que tiene que ver con las posibilidades de proveer a los profesores de una clara visión de lo que ha de lograrse con la implementación y con concretar esa visión en términos de saber profesional y habilidades de los docentes. La segunda es la "presión direccional" que refiere a un nivel

  6. LAND REFORM IN UKRAINE: HISTORIOGRAPHICAL ANALYSIS

    Full Text Available Modern land reform, that continues in Ukraine since the beginning of the 90-th of ХХ century, is a logical result of the functioning of society and the state.. It’s prerequisites becames, especially full monopolization of state on ownership of land; absence of payment for land as one of the means of ensuring the rational use of lands; absence on workers motivation for intensive work on the land, etc.. These and other preconditions contributed to soil degradation, production of agricultural products with exceeding of maximum allowable concentrations of pollutants, development of diseases, undermine the gene pool of nature and man. Mentioned reasons determined the goal and objectives of modern land reform, which were originally set out in the preamble to the Resolution of the Verkhovna Rada of Ukraine from December 18, 1990 «On Land Reform» with following changes and additions, and in the implementation of the land-reformation measures gained more complete content. Conducted analysis shows that land reform in Ukraine leads to a change of ownership of land, contributes to solving problems of citizens by land plots, enactment of payment for land usecreation of conditions for the development of land market. Thus changing land relations, is formed legal and regulatory framework of land reform and land market. However, positive developments in the implementation of land reform to end of the 90-th years have not led to a radical and effective upgrade of agricultural production, recovery of investment processes in other branches of industry, improving of welfare of the population. Land reform measures didn’t receive adequate financial support. The ultimate goal - an economically-effective and environmentally safe use of land in Ukraine - has not been achieved. Further reforming of land relations contributed to the adoption in October 2001 of the Land Code of Ukraine in the new edition that created the legal principles of land reform. Since it

    Ammar, Walid; Awar, May

    2012-01-01

    The Ministry of Labor (MOL) has submitted to the Council of Ministers a social security reform plan. The Ministry of Public Health (MOPH) considers that health financing should be dealt with as part of a more comprehensive health reform plan that falls under its prerogatives. While a virulent political discussion is taking place, major stakeholders' inputs are very limited and civil society is totally put away from the whole policy making process. The role of the media is restricted to reproducing political disputes, without meaningful substantive debate. This paper discusses health insurance reform from labor market as well as public health perspectives, and aims at launching a serious public debate on this crucial issue that touches the life of every citizen.

  19. The road half traveled: agricultural market reform in Sub-Saharan Africa

    Directory of Open Access Journals (Sweden)

    Kherallah Mylène

    2002-11-01

    Full Text Available This article reviews the extensive evidence on agricultural market reforms in Sub-Saharan Africa and summarises the impact reforms have had on market performance, agricultural production, use of modern inputs, and poverty. It offers eight recommendations for completing the reform process and developing a new agenda for agricultural markets in Sub-Saharan Africa. The reform experience in Sub-Saharan Africa has varied widely across countries and crop subsectors. The available evidence shows clear progress in some areas and mixed results in others. Most reforms were only partially implemented and policy reversal was common. Once implemented, however, reforms have increased competition and reduced marketing margins, benefiting both producers and consumers. Reforms have also boosted export crop production. On the other hand, food crop production has stagnated and yields have not improved. Further expansion of private trade is constrained by lack of access to credit, uncertainty about the government’s commitment to reform, and high transaction costs.

    Jinliang Yuan; Fuan Ren; Jinliang Yuan; Bengt Sunden

    2006-01-01

    There are various physical processes (such as mass, heat and momentum transport) integrated with catalytic chemical reactions in a methane steam reforming duct. It is often found that endothermic and exothermic reactions in the ducts are strongly coupled by heat transfer from adjacent catalytic combustion ducts. In this paper, a three-dimensional calculation method is developed to simulate and analyze steam reforming of methane, and the effects on various transport processes in a steam reforming duct. The reformer conditions such as mass balances associated with the reforming reactions and gas permeation to/from the porous catalyst layer are applied in the analysis. The predicted results are presented and discussed for a composite duct consisting of a porous catalyst reaction area, the gas flow duct and solid layers. Parametric studies are conducted and the results show that the variables, such as fuel reformer temperatures and catalyst loadings, have significant effects on the transport processes and reformer performance.

    Full Text Available During the past 20 years, most settlements of the Brazilian Agrarian Reform (AR have been established in or near better-preserved natural ecosystems, where environmental impact is likely to be negative and contribute to natural resources degradation. The objective of this work is providing a first, comprehensive insight of the impacts related to the environmental quality of these settlements, based on the primary survey of 4,340 AR settlements installed between 1985 and 2001. An index was calculated to integrate different aspects of environmental impacts in one single number. The index showed significant regional variation, with lower values (low environmental quality for the North and Northeast of Brazil, intermediate values for the Central-west and Southeast, and high values for the South. Environmental impacts resulting from AR and settlement creation are slowly decreasing with time, but are still very high in absolute values. The lack of protection of riparian areas, cultivation of legal reserves, and deforestation, are the main concerns related to environmental impacts.Até o presente a maioria dos assentamentos da Reforma Agrária brasileira (AR têm sido estabelecidos em ou perto de ambientes preservados, nos quais impactos ambientais negativos são esperados e podem levar à degradação dos recursos naturais.

    Full Text Available In 2014 we celebrate the 150th anniversary of the Judicial Reform in Russia. The 1860s are known as a time of major reforms in various spheres of life, one of them being the Judicial Reform adopted in 1864. Before 1864 civil procedure was considered to be the classical form of inquisitorial justice1 with active judges and passive parties. Inquisitorial procedure was a written process conducted in secret with no legal representatives in court, and with formal evaluation of evidence (otsenka dokazatel’stv. Instead of an inquisitorial procedure the Judicial Reform introduced an adversarial system with active parties and more or less passive judges, an open, oral (public process, legal representatives, and free evaluation of evidence. So, for Russian procedure it was a revolution as it happened in other countries of Europe, which turned away from an inquisitorial to an adversarial system of justice.

    Ahmed, Shabbir; Kumar, Romesh; Krumpelt, Michael

    1999-01-01

    A partial oxidation reformer comprising a longitudinally extending chamber having a methanol, water and an air inlet and an outlet. An igniter mechanism is near the inlets for igniting a mixture of methanol and air, while a partial oxidation catalyst in the chamber is spaced from the inlets and converts methanol and oxygen to carbon dioxide and hydrogen. Controlling the oxygen to methanol mole ratio provides continuous slightly exothermic partial oxidation reactions of methanol and air producing hydrogen gas. The liquid is preferably injected in droplets having diameters less than 100 micrometers. The reformer is useful in a propulsion system for a vehicle which supplies a hydrogen-containing gas to the negative electrode of a fuel cell.

    Full Text Available This special issue traces multifaceted readings of criminal law reform in the context of developments in Australia, North America and Europe. It addresses a range of criminal law legislative regimes, frameworks and issues confronting criminal law reform including as they relate to family violence, organisational liability for child sexual abuse, drug-driving and Indigenous under-representation on juries. In doing so, the articles variously assess the impacts of past criminal law reforms, current processes of reform, areas in need of future reform and the limitations of reform. It poses a number of challenges: Who does law reform serve? What principles should guide the work of criminal justice reform? What is the role and responsibility of universities in law reform? Who are the natural allies of academics in agitating for reform? Is reform of criminal law enough for progressive social change? Do public inquiries and law reform assist with progressive change or do they have the potential to undermine the struggle for more humane and equitable social responses?

  13. Bureaucratic Reform in Irrigation: A Review of Four Case Studies

    Directory of Open Access Journals (Sweden)

    Diana Suhardiman

    2014-10-01

    Full Text Available Poor performance of government-managed irrigation systems persists globally. This paper argues that addressing performance requires not simply more investment or different policy approaches, but reform of the bureaucracies responsible for irrigation management. Based on reform experiences in The Philippines, Mexico, Indonesia, and Uzbekistan, we argue that irrigation (policy reform cannot be treated in isolation from the overall functioning of government bureaucracies and the wider political structure of the states. Understanding of how and why government bureaucracies shape reform processes and outcomes is crucial to increase the actual significance of reforms. To demonstrate this, the paper links reform processes in the irrigation sector with the wider discourse of bureaucratic reform in the political science, public administration, and organisational science literature. Doing so brings to light the need for systematic comparative research on the organisational characteristic of the irrigation bureaucracies, their bureaucratic identities, and how these are shaped by various segments within the bureaucracies to provide the insights needed to improve irrigation systems performance.

    Among the competitive electricity reforms that have been implemented in Europe and the US for the last 18 years, none has 'survived' over several years without major changes. Their changing nature raises the question of their adaptability. Two characteristics of reforms play a key role on their adaptation properties. Firstly, they are 'modular' objects in the sense of [Baldwin, C., 2008. Where do transactions come from? Modularity, transactions, and the boundaries of firms. Industrial and Corporate Change 17 (1), 155-195]. Secondly, they are produced in an institutional process which leads to 'incomplete' rules and designs [Pistor, K., Xu, C., 2003. Incomplete law.

Comparative economic organization: the analysis of discrete structural alternatives. Administrative Science Quarterly 36 (2), 269-296] for contracts: (1) in case of small disturbances, adaptations are realized quasi-automatically, by autonomous decisions of the institutions governing the implementation of reforms; (2) in case of middle-range disturbances, adaption is made by Coasian bargaining; (3) finally, in case of strong disturbances, or when bargaining is not feasible, the adaptation of reforms is in the hands of legislative and executive institutions [North, D.C., 2005.

    Full Text Available In June 1993, Governor William Weld signed into law the Massachusetts Education Reform Act (MERA. MERA greatly increased the state role both in funding public education and in guiding the local educational process. The state’s role changed to incorporate setting curriculum frameworks and holding schools accountable for student performance. Because MERA was designed to be a systemic reform of education, all of the various state activities and policies needed to fit together into a coherent whole based on state educational standards.

  2. Steam reformer with catalytic combustor

    Voecks, Gerald E. (Inventor)

    1990-01-01

    A steam reformer is disclosed having an annular steam reforming catalyst bed formed by concentric cylinders and having a catalytic combustor located at the center of the innermost cylinder. Fuel is fed into the interior of the catalytic combustor and air is directed at the top of the combustor, creating a catalytic reaction which provides sufficient heat so as to maintain the catalytic reaction in the steam reforming catalyst bed. Alternatively, air is fed into the interior of the catalytic combustor and a fuel mixture is directed at the top. The catalytic combustor provides enhanced radiant and convective heat transfer to the reformer catalyst bed.

    2015-01-01

    Increasing CO 2 emission problems create urgent challenges for alleviating global warming, and the capture of CO 2 has become an essential field of scientific research. In this study, a finite volume method (FVM) coupled with thermochemical kinetics was developed to analyze the solar driven CO 2 methane reforming process in a metallic foam reactor. The local thermal non-equilibrium (LTNE) model coupled with radiative heat transfer was developed to provide more temperature information. A joint inversion method based on chemical process software and the FVM coupled with thermochemical kinetics was developed to obtain the thermochemical reaction parameters and guarantee the calculation accuracy. The detailed thermal and thermochemical performance in the metal foam reactor was analyzed. In addition, the effects of heat flux distribution and porosity on the solar driven CO 2 methane reforming process were analyzed. The numerical results can serve as theoretical guidance for the solar driven CO 2 methane reforming application. - Highlights: • Solar driven CO 2 methane reforming process in metal foam reactor is analyzed. • FVM with chemical reactions was developed to analyze solar CO 2 methane reforming. • A joint inversion method was developed to obtain thermochemical reaction parameters. • Results can be a guidance for the solar driven CO 2 methane reforming application.

    2007-01-01

    Although South Asian developing countries had initiated some form of electric power sector reform in the 1990s, often under external lending agency pressures, not much progress has been made so far and there is hardly any noteworthy example of a successful reform in the region. This paper provides a brief review of power sector reform efforts in five South Asian countries and uses an institutional economics framework to identify the factors shaping the success of power sector reforms. Four factors, namely instability of rule-makers, poor overall acceptance, slow adaptation and poor transition management are identified and their effect on the reform process of South Asia are analysed. The paper finds that political instability has affected the power sector reform of the region, making hard decisions difficult to take. Slow progress of reform has also affected the sector viability, as signs of adverse effects on the power sector investment and performance are already visible

  7. The 2015 hospital treatment choice reform in Norway: Continuity or change?

    Science.gov (United States)

    Ringard, Ånen; Saunes, Ingrid Sperre; Sagan, Anna

    2016-04-01

    In several European countries, including Norway, polices to increase patient choice of hospital provider have remained high on the political agenda. The main reason behind the interest in hospital choice reforms in Norway has been the belief that increasing choice can remedy the persistent problem of long waiting times for elective hospital care. Prior to the 2013 General Election, the Conservative Party campaigned in favour of a new choice reform: "the treatment choice reform". This article describes the background and process leading up to introduction of the reform in the autumn of 2015. It also provides a description of the content and discusses possible implications of the reform for patients, providers and government bodies. In sum, the reform contains elements of both continuity and change. The main novelty of the reform lies in the increased role of private for-profit healthcare providers. Copyright © 2016 The Authors.

    Full Text Available The purpose of this paper is to elaborate criteria by which the principles of curriculum reform can be judged. To this end, the paper presents an overview of standard critiques of medical education and examines the ways medical curriculum reforms have responded to these critiques. The paper then sets out our assessment of these curriculum reforms along three parameters: pedagogy, educational context, and knowledge status. Following on from this evaluation of recent curriculum reforms, the paper puts forward four criteria with which to gauge the adequacy medical curriculum reform. These criteria enable us to question the extent to which new curricula incorporate methods and approaches for ensuring that its substance: overcomes the traditional opposition between clinical and resource dimensions of care; emphasizes that the clinical work needs to be systematized in so far as that it feasible; promotes multi-disciplinary team work, and balances clinical autonomy with accountability to non-clinical stakeholders.

    Full Text Available The Agrarian Reform, from the 1988 Federal Constitution, is premised on state intervention in private property in the event of breach of the property social function and the consequent allocation of such areas for the landless rural workers, making it beneficiaries of agricultural policy. The need for intervention arises especially evil and historical land concentration in Brazil, which favored the existence and maintenance of a class of landless laborers, with no room to work and production, even though subsistence. After state intervention and from the creation of the settlement project, a number of public policies implemented by INCRA - National Institute of Colonization and Agrarian Reform, such as credits and technical assistance. It has been provided in the Constitution titration of such beneficiaries, however, in 2014, it was promulgated and publicized the Law 13,001, which will implement a massive policy titration, which will lead the transfer of public assets to the private and in consequence the alternative this particular also sell to third parties, which brings the unwanted possibility of re-concentration.

    2013-05-01

    Full Text Available This qualitative ethnographic case study explored the evolution of a public urban high school in its 3rd year of small school reform. The study focused on how the high school proceeded from its initial concept, moving to a small school program, and emerging as a new small high school. Data collection included interviews, observations, and document review to develop a case study of one small high school sharing a multiplex building. The first key finding, “Too Many Pieces, Not Enough Glue,” revealed that the school had too many new programs starting at once and they lacked a clear understanding of their concept and vision for their new small school, training on the Montessori philosophies, teaching and learning in small schools, and how to operate within a teacher-cooperative model. The second key finding, “A Continuous Struggle,” revealed that the shared building space presented problems for teachers and students. District policies remain unchanged, resulting in staff and students resorting to activist approaches to get things done. These findings offer small school reform leaders suggestions for developing and sustaining a small school culture and cohesion despite the pressures to revert back to top-down, comprehensive high school norms.

  17. Pension Reform in China.

    Science.gov (United States)

    Liu, Tao; Sun, Li

    2016-01-01

    This article analyzes China's pension arrangement and notes that China has recently established a universal non-contributory pension plan covering urban non-employed workers and all rural residents, combined with the pension plan covering urban employees already in place. Further, in the latest reform, China has discontinued the special pension plan for civil servants and integrated this privileged welfare class into the urban old-age pension insurance program. With these steps, China has achieved a degree of universalism and integration of its pension arrangement unprecedented in the non-Western world. Despite this radical pension transformation strategy, we argue that the current Chinese pension arrangement represents a case of "incomplete" universalism. First, its benefit level is low. Moreover, the benefit level varies from region to region. Finally, universalism in rural China has been undermined due to the existence of the "policy bundle." Additionally, we argue that the 2015 pension reform has created a situation in which the stratification of Chinese pension arrangements has been "flattened," even though it remains stratified to some extent.

    Coal and lignite will play a significant role in the future energy production. However, the technical options for the reduction of CO 2 emissions will define the extent of their share in the future energy mix. The production of synthetic or substitute natural gas (SNG) from solid fossil fuels seems to be a very attractive process: coal and lignite can be upgraded into a methane rich gas which can be transported and further used in high efficient power systems coupled with CO 2 sequestration technologies. The aim of this paper is to present a modeling analysis comparison between substitute natural gas production from coal by means of allothermal steam gasification and autothermal oxygen gasification. In order to produce SNG from syngas several unit operations are required such as syngas cooling, cleaning, potential compression and, of course, methanation reactors. Finally the gas which is produced has to be conditioned i.e. removal of unwanted species, such as CO 2 etc. The heat recovered from the overall process is utilized by a steam cycle, producing power. These processes were modeled with the computer software IPSEpro™. An energetic and exergetic analysis of the coal to SNG processes have been realized and compared. -- Highlights: ► The production of SNG from coal is examined. ► The components of the process were simulated for integrated autothermal or allothermal coal gasification to SNG. ► The energetic and exergetic evaluation of the two processes is presented.

  6. Regulatory reform of Finnish environmental policy

    Energy Technology Data Exchange (ETDEWEB)

    Sairinen, R.

    2000-07-01

    The main question of this study concerns the regulatory reform i.e. formation and design of new policy instruments in the Finnish environmental policy. The research question is divided into two parts: (1) How have the new policy instruments evolved and been designed (2) What are the political, administrative, historical and ideological factors underlying the processes of policy instrument formation and design? Three main approaches for analysis are introduced: the model of policy instrument choice by Linder and Peters, the model of policy explanation by Jaenicke, and the concept of governmentality developed by Foucault. Within the developed theoretical framework, the general societal background of regulatory reform is composed of the various features of 'environmental governmentality'. The research questions are divided into two empirical research tasks. (1) Analysis of the historical development of Finnish environmental governing and policy style provides background information about the national institutional settings and policy cultures in order to understand the role of the new policy instruments in the Finnish environmental policy during last two decades. Here, Finnish environmental policy divides into consensual pollution policies and adversial nature conservation. Four main periods of environmental governmentality in Finland is presented: the early nature conservation initiatives (1800-1939), the neglect of environmental issues (1945-1969), the environmental institutionalisation (1970-1986), and the regulatory reform (1987-). (2) The contextual case studies concerns: the drafting of the EIA Act in 1982-1994; the formation of the carbon tax policy in 1989-1996; and the implementation of voluntary environmental agreements in 1987-99. The study shows that regulatory reform has not been an easy policy process in Finland. There has been no common environmental governmentality behind the on-going regulatory reform. The new policy instruments have been

    2012-10-01

    Full Text Available Yemen is currently undergoing a major political transition, yet many economic challenges—including fuel subsidy reform—remain highly relevant. To inform the transition process with respect to a potential subsidy reform, we use a dynamic computable general equilibrium and microsimulation model for Yemen; we show that overall growth effects of subsidy reduction are positive in general, but poverty can increase or decrease depending on reform design. A promising strategy for a successful reform combines fuel subsidy reduction with direct income transfers to the poorest one-third of households during reform, and productivity-enhancing investment in infrastructure, plus fiscal consolidation. Public investments should be used for integrating economic spaces and restructuring of agricultural, industrial and service value chains in order to create a framework that encourages private-sector-led and job-creating growth.

  8. The Chilean health system: 20 years of reforms.

    Science.gov (United States)

    Manuel, Annick

    2002-01-01

    The Chilean health care system has been intensively reformed in the past 20 years. Reforms under the Pinochet government (1973-1990) aimed mainly at the decentralization of the system and the development of a private sector. Decentralization involved both a deconcentration process and the devolution of primary health care to municipalities. The democratic governments after 1990 chose to preserve the core organization but introduced reforms intended to correct the system's failures and to increase both efficiency and equity. The present article briefly explains the current organization of the Chilean health care system. It also reviews the different reforms introduced in the past 20 years, from the Pinochet regime to the democratic governments. Finally, a brief discussion describes the strengths and weaknesses of the system, as well as the challenges it currently faces.

  9. Welfare reform at 15 and the state of policy analysis.

    Science.gov (United States)

    Pimpare, Stephen

    2013-01-01

    This article offers a review of welfare reform evaluation studies, summarizing research that has generated a consensus among mainstream policy analysts that the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA) has had few effects beyond caseload reductions and increases in employment. Given that supporters and opponents alike expected the law to have profound consequences, the article considers two ways to explain this surprising outcome, showing that (1) quantitative policy analysis has been ill equipped to capture the PRWORA's effects and (2) expectations were nonetheless wrong because they failed to appreciate how thoroughly Aid to Families with Dependent Children had already been eroded in the decades prior to its reform. Welfare reform was not the beginning of a process of policy change; it was the end of one. In response to these findings, the article describes how a more critical perspective on reform matters for social work researchers, advocates, and practitioners.

  10. Transforming Economies. The Case of the Norwegian Electricity Market Reform

    International Nuclear Information System (INIS)

    Olsen, Per Ingvar

    2000-01-01

    The topic of this thesis is the shaping of modern economies, represented by a case-study of the Norwegian electricity market reform process. The essential questions raised are: Why are industries and economies organized the way they are? and Why and how do they occasionally experience fairly radical transformations during which we come to see their organizational structures and associated behaviors in entirely different ways? To answer these questions, the author has followed a radical market-making economic reform process through its many projects, processes and rivalries, from its roots in specific historical controversies through its major breakthrough and into a stabilized new economic system. A major argument through out the analysis is that economics as a scientific activity and -community plays a particularly important role in the re-shaping of economic systems. Large scale economic reforms are found to be dependent upon scientific and political powers and legitimacy which results from broad consensus within the relevant scientific communities. In order to make his point, the author presents and discusses various historical economic reform initiatives both within the Norwegian electricity sector, within other sectors of the economy and in other countries. He also presents elements of a broad process of reorientation within economics during the 1970s and follows these new conceptions up to the electricity market reform process in the late 1980s. The analysis tries to explain why Norway became a hotbed for market reform of the technically integrated and institutionally complex and locked-in electricity system, but also fries to extract medium range insights about economic reform processes and to discuss more general implications for other large scale economic reform projects as well as for economic theories about economic change - through a rethinking of some of the basics in economic thought. The thesis is separated into four parts. The first part discusses

  13. Ideology drives health care reforms in Chile.

    Science.gov (United States)

    Reichard, S

    1996-01-01

    The health care system of Chile evolved from rather unique historical circumstances to become one of the most progressive in Latin America, offering universal access to all citizens. Since the advent of the Pinochet regime in 1973, Chile has implemented Thatcherite/Reaganite reforms resulting in the privatization of much of the health care system. In the process, state support for health care has been sharply curtailed with deleterious effects on health services. As Chile emerges from the shadow of the Pinochet dictatorship, it faces numerous challenges as it struggles to rebuild its health care system. Other developing nations considering free-market reforms may wish to consider the high costs of the Chilean experiment.

    2010-01-01

    In this paper we assess the IMF approach to economic reform in developing countries. The impact of IMF program participation on economic growth has been evaluated empirically in a cross-country literature, with little evidence of IMF programs having been successful. This suggests that a fresh...... of IMF programs is a high degree of policy rigidity. This is in contrast with studies which hold that unleashing an economy's growth potential hinges on a set of well-targeted policy interventions aimed at removing country-specific binding constraints. The process of locating constraints that bind...... involves growth diagnostics and policy trialing. This approach maintains that not all distortions are equally important and, by extension, not all policy reforms. From this point of view, IMF programs based on a list of standard conditionalities will not accomplish much. But policy trialing is more...

    Reference price systems for prescription drugs have found widespread use as cost containment tools. Under such regulatory regimes, patients co-pay a fraction of the difference between pharmacy retail price of the drug and a reference price. Reference prices are either externally (based on drug...... prices in other countries) or internally (based on domestic drug prices) determined. In a recent study, we analysed the effects of a change from external to internal reference pricing in Denmark in 2005, finding that the reform led to substantial reductions in prices, producer revenues, and expenditures...... for patients and the health insurance system. We also estimated an increase in consumer welfare but the size effect depends on whether or not perceived quality differences between branded and other drugs are taken into account....

    The Norwegian hospital reform of 2002 was an attempt to make restructuring of hospitals easier by removing politicians from the decision-making processes. To facilitate changes seen as necessary but politically difficult, the central state took over ownership of the hospitals and stripped the county politicians of what had been their main responsibility for decades. This meant that decisions regarding hospital structure and organization were now being taken by professional administrators and not by politically elected representatives. The question raised here is whether this has had any effect on the speed of restructuring of the hospital sector. The empirical part is a case study of the restructuring process in Innlandet Hospital Trust (IHT), which was one of the largest enterprise established after the hospital reform and where the vision for restructuring was clearly set. Different sources of qualitative data are used in the analysis. These include interviews with key actors, observational data and document studies. The analysis demonstrates how the new professional leaders at first acted in accordance with the intentions of the hospital reform, but soon chose to avoid the more ambitious plans for restructuring the hospital structure and in fact reintroduced local politics into the decision-making process. The analysis further illustrates how local networks and engagement of political representatives from all levels of government complicated the decision-making process surrounding local structural reforms. Local political representatives teamed up with other actors and created powerful networks. At the same time, national politicians had incentives to involve themselves in the processes as supporters of the status quo. Because of the incentives that faced political actors and the controversial nature of major hospital reforms, the removal of local politicians and the centralization of ownership did not necessarily facilitate reforms in the hospital structure

    Highlights: ► A heat and mass transfer model is developed for a compact reformer. ► Hydrogen production from methane steam reforming is simulated. ► Increasing temperature greatly increases the reaction rates at the inlet. ► Temperature in the downstream is increased at higher rate of heat supply. ► Larger permeability enhances gas flow and reaction rates in the catalyst layer. - Abstract: Compact reformers (CRs) are promising devices for efficient fuel processing. In CRs, a thin solid plate is sandwiched between two catalyst layers to enable efficient heat transfer from combustion duct to the reforming duct for fuel processing. In this study, a 2D heat and mass transfer model is developed to investigate the fundamental transport phenomenon and chemical reaction kinetics in a CR for hydrogen production by methane steam reforming (MSR). Both MSR reaction and water gas shift reaction (WGSR) are considered in the numerical model. Parametric simulations are performed to examine the effects of various structural/operating parameters, such as pore size, permeability, gas velocity, temperature, and rate of heat supply on the reformer performance. It is found that the reaction rates of MSR and WGSR are the highest at the inlet but decrease significantly along the reformer. Increasing the operating temperature raises the reaction rates at the inlet but shows very small influence in the downstream. For comparison, increasing the rate of heat supply raises the reaction rates in the downstream due to increased temperature. A high gas velocity and permeability facilitates gas transport in the porous structure thus enhances reaction rates in the downstream of the reformer.

    The Study of dentistry in Germany is in need of reform. The actual regulation on licensing dentists in Germany is from 1955, with the last changes made in 1993. Recently there have been different initiatives related to reform: a national catalogue of competency-based learning objectives in dental education (NKLZ), changes and stipulations in the respective rules relating to undergraduate curriculum in dental medicine, and an initiative of the Germany Ministry of Health to tackle and reorganize dental education in Germany.This article presents and reflects on these reform efforts in the context of actual teaching in Germany, Europe, and the United States.The reform process is an opportunity for dental education in German faculties of medicine. New dentistry programs are allowed at all faculties with model educational programs in medicine. Therefore, an example of actual reform efforts are presented based on the experiences of Hamburg. Research on dental educational programs revealed interesting approaches in dental education in other European faculties of medicine. Selected faculties were visited. These experiences led to the formulation of five main goals of reform: interdisciplinary study, problem- and symptom-based learning, early patient contact, science-based education, and communication training. The main goal is a dental education program designed along science-based, prevention-oriented, multidisciplinary, and individualized dental care that contributes to the life-long oral health of patients.

  6. Implementing Lean Health Reforms in Saskatchewan

    Greg Marchildon

    2013-07-01

    Full Text Available Saskatchewan has gone further than any other Canadian province in implementing health system process improvements using Lean, a production line discipline that originated with the automobile industry. The goal of the Lean reform is to reduce waste and improve quality and overall health system performance by long-term changes in behaviour. Lean enjoys a privileged position on the provincial government’s agenda because of the policy’s championing by the Deputy Minister of Health and the policy’s fit with the government’s patient-centred care agenda. The implementation of reform depends on a major investment of time in the training and Lean-certification of key leaders and managers in the provincial health system. The Saskatchewan Union of Nurses, the union representing the single largest group of health workers in the province, has agreed to co-operate with the provincial government in implementing Lean-type reforms. Thus far, the government has had limited independent evaluation of Lean while internal evaluations claim some successes.

From an appropriate health outcomes indicator, it appears that while still being one of the most performing countries, China’s relative advance decreased during the reforms. Consistent with the fact that the health system had to rely more and more on private expenditures, we find an increasing impact of income on infant survival. We also show that relative prices matter for infant survival: for a given ...

  11. Health Reform Requires Policy Capacity

    Directory of Open Access Journals (Sweden)

    Pierre-Gerlier Forest

    2015-05-01

    Full Text Available Among the many reasons that may limit the adoption of promising reform ideas, policy capacity is the least recognized. The concept itself is not widely understood. Although policy capacity is concerned with the gathering of information and the formulation of options for public action in the initial phases of policy consultation and development, it also touches on all stages of the policy process, from the strategic identification of a problem to the actual development of the policy, its formal adoption, its implementation, and even further, its evaluation and continuation or modification. Expertise in the form of policy advice is already widely available in and to public administrations, to well-established professional organizations like medical societies and, of course, to large private-sector organizations with commercial or financial interests in the health sector. We need more health actors to join the fray and move from their traditional position of advocacy to a fuller commitment to the development of policy capacity, with all that it entails in terms of leadership and social responsibility

  12. Reforming health care in Hungary.

    Science.gov (United States)

    Császi, L; Kullberg, P

    1985-01-01

    Over the past two decades Hungary has initiated a series of social and economic reforms which have emphasized decentralization of control and the reintroduction of market mechanisms into the socialized economy. These reforms both reflect and reinforce a changing social structure, in particular the growing influence of upper class special interest groups. Market reforms are an expression of concurrent ideological shifts in Hungarian society. We examined the political significance of three recent proposals to reform health services against the backdrop of broader social and economic changes taking place. The first proposes a bureaucratic reorganization, the second, patient co-payments, and the third, a voucher system. The problems each proposal identifies, as well as the constituency each represents, reveal a trend toward consolidation of class structure in Hungary. Only one of these proposals has any potential to democratize the control and management of the heath care system. Moreover, despite a governmental push toward decentralization, two of these proposals would actually increase centralized bureaucratic control. Two of the reforms incorporate market logic into their arguments, an indication that the philosophical premises of capitalism are re-emerging as an important component of the Hungarian world-view. In Hungary, as well as in other countries, social analysis of proposed health care reforms can effectively illuminate the social and political dynamics of the larger society.

  13. Power sector reform in India: current issues and prospects

    International Nuclear Information System (INIS)

    Singh, Anoop

    2006-01-01

    Power sector reforms in India were initiated at a juncture when the sector was plagued with commercial losses and burgeoning subsidy burden. Investment in the sector was not able to keep pace with growing demand for electricity. This paper takes stock of pre-reform situation in Indian power sector and identifies key concerns that led to initiation of the process of reform. The paper discusses major policy and regulatory changes undertaken since the early 1990s. The paper also illustrates changes in the market structure as we move along the reform process. We also discuss some of the major provisions of the recently enacted Electricity Act 2003 that aims to replace the prevailing acts which govern the functioning of the power sector in the country. In this context, we discuss two issues arising out of it, namely open access and multi-year tariff that we think would have a significant bearing on the performance of the sector in the near future. The paper also evaluates the reform process in the light of some of the regulatory changes undertaken. Finally, the paper briefly discusses the issues involved in introduction of competition in the power sector primarily through development of a market for bulk power

    The main objective of this work is to investigate the carbon deposition during reforming of hydrocarbons in a Chemical Looping Reformer (CLR). This knowledge is needed to asses the viability of the CLR technology in reforming tar from biomass gasification preserving lighter hydrocarbons and minimizing the carbon formation during the process. Two different setups were used to test the reactivity of the different samples in the conditions of interest for the tar reforming process: 1) Fixed bed flow reactor (FR), and 2) Thermogravimetric analyzer (TGA). In the experiments, the gas atmosphere was switched from reducing to oxidizing atmosphere in every cycle. During the oxidizing cycle, the carrier was regenerated using a mixture of oxygen and nitrogen. Four different oxygen carriers based on nickel (Ni40 and Ni60), manganese (Mn) and ilmenite (Fe) were tested. In the tests, toluene was used to simulate the tars. The Fe and the Mn carrier reacted to a small extent with methane at the highest temperature studied, 800 degrees C. The Ni-carriers did not react at 600 degrees C at first, but they showed some reactivity after having been activated at the higher temperature. Carbon formation occurred with the Ni-carriers, more so with the Ni60 than the Ni40. Ni40, Mn and Fe were activated at the higher temperature. However, Fe showed only low capacity. Ni60 showed no capability of tar reforming. Ni40 showed a high tendency to carbon formation at 800 degrees C, but the formation could be lowered by changing some parameters. Mn formed almost no carbon. Ni40 and Mn were chosen for further studies. Carbon deposition occurred for both Ni40 and Mn, but the amount deposited for Ni40 was about 10 times bigger. Ni40 reacted with the methane and toluene only at 800 degrees C. The conversion over Mn was not as big as for toluene alone. Carbon was formed from carbon monoxide on the Ni40 carrier and on the Mn, but to a much less extent on the latter one. The presence of hydrogen decreased

    Full Text Available An unbridled globalization based on a simple premise about earnings and profit may be detrimental to the livelihood of many thousands of individuals. The greed and utter selfishness that result from the adherence to this sort of business practice are the two things that generate more unemployment, misery and degradation than most other characteristics of the human species. These considerations present the challenge for Western societies and call for the implementation of other principles, standards and procedures, such as cooperation, cohesion, development objectives and social responsibility. In the first part of the paper this approach is tested in the case of the EU-US foreign exchange relationships. The second part of the paper raises more general and fundamental issues. While adhering to the Schumpeter-type innovation environment, it aims to introduce the social dimension ahead of the immediate competitiveness and, therefore, argues for the fundamental reform of the catechism of the capitalist manager. The EU, due to its advanced integration, is relatively well-equipped to move towards the new economic system.

    A heat exchanger uses the heat from processed fuel gas from a reformer for a fuel cell to superheat steam, to preheat raw fuel prior to entering the reformer and to heat a water-steam coolant mixture from the fuel cells. The processed fuel gas temperature is thus lowered to a level useful in the fuel cell reaction. The four temperature adjustments are accomplished in a single heat exchanger with only three heat transfer cores. The heat exchanger is preheated by circulating coolant and purge steam from the power section during startup of the latter.

    Compared with their higher-income counterparts, children growing up in low-income families in the United States typically complete less schooling, report worse health, and work and earn less in adulthood. Moreover, changes in the American economy over the last 40 years have raised the level of skills and qualifications that children need to obtain a good middle-class job, as well as making it much more difficult for children from low-income families to attend schools that support their learning of these skills. We first review strategies used in the past to improve K-12 schooling-including investing more money, introducing more accountability, and putting in place new governance structures (eg, charter schools)-and show why these strategies have been relatively ineffective. Drawing on the research literature and case studies, we then describe education reform strategies for prekindergarten programs and for elementary, middle, and high schools that may help meet these challenges. All of the initiatives described in our case studies provide ample opportunities for teachers and school leaders to improve their skills through coaching and other professional development activities; incorporate sensible systems of accountability, including requiring teachers to open their classrooms to the scrutiny of colleagues and school leaders and to work with their colleagues to improve their teaching practices; and incorporate high academic standards, such as those described in the Common Core State Standards. By focusing directly on improving teaching and promoting learning, these successful initiatives have boosted the achievement of low-income children. They show that it is indeed possible to make a real difference in the life chances of low-income children. Copyright © 2016 Academic Pediatric Association. Published by Elsevier Inc.

  5. Immigration reform, American style.

    Papademetriou, D G

    1984-01-01

    This article reviews the background of the proposed Immigration and Reform Act (also known as the Simpson-Mazzoli bill), which seeks to overhaul US immigration law for the first time since 1952. This bill is consistent with President Reagan's hard line on border enforcement and mandates stiff penalties for those who transport illegal aliens for commercial advantage or private profit. It further offers Mexico preferential treatment in immigration (40,000 additional visas/year). It includes an amnesty program to offer legal status to qualified illegal residents. The bill directs the President to develop a secure national worker identification system and would create a large-scale temporary foreign agricultural program for perishable commodities. Agricultural workers' families would not be eligible to accompany them unless they also obtain temporary visas. Foreign temporary workers, employable only in cases where local domestic workers are not available, must be provided with wages and working conditions equal to those prevailing among domestic workers. Stiff penalties are stipulated for employers who fail to abide with the terms of the program. In the author's opinion, this bill fails to appreciate the global character of international migration and its complexity. It relects a fundamental ambivalence about a strictly controlled main gate versus a back door approach to immigration as well as the conflicting images of the US as a nation of immigrants versus the historical reality of American nativism and xenophobia. Needed are comprehensive initiatives whose mutually reinforcing components can address the multiple dimensions of the immigration problem within a framework that does not ignore workers who have contributed to the economic well-being of the US, regardless of their legal status.

  6. Lessons learned from Brazilian natural gas industry reform

    International Nuclear Information System (INIS)

    Mathias, Melissa Cristina; Szklo, Alexandre

    2007-01-01

    Over the past decades many countries have reformed their infrastructure industries. Although these reforms have been broadly similar for the most part, aiming at introducing competition in potentially competitive segments, the contexts in which they have been carried out differ. This is due to the past regulatory experience in each country, the maturity of the industry and/or the number of agents when the reform process started. The Brazilian natural gas reform stands out due to the country's singular conditions. The development of the natural gas industry in Brazil was grounded on stepping up supplies through integration with neighboring nations (particularly Bolivia) and establishing a competitive environment by lowering the barriers hampering the arrival of new investors. However, natural gas is located at the crossroads of two main energy chains: oil and hydroelectricity. This article analyzes the Brazilian natural gas reform, and extracts lessons from this process. The low capillarity of transportation and distribution systems continues to be the main bottleneck of the country's natural gas industry. The challenges of the new legal framework are to encourage investments in networks and guarantee supply, to allow the industry to consolidate and mature, against a backdrop of rapid changes in the world market.

  10. Modeling efficiency and water balance in PEM fuel cell systems with liquid fuel processing and hydrogen membranes

    Science.gov (United States)

    Pearlman, Joshua B.; Bhargav, Atul; Shields, Eric B.; Jackson, Gregory S.; Hearn, Patrick L.

    Integrating PEM fuel cells effectively with liquid hydrocarbon reforming requires careful system analysis to assess trade-offs associated with H 2 production, purification, and overall water balance. To this end, a model of a PEM fuel cell system integrated with an autothermal reformer for liquid hydrocarbon fuels (modeled as C 12H 23) and with H 2 purification in a water-gas-shift/membrane reactor is developed to do iterative calculations for mass, species, and energy balances at a component and system level. The model evaluates system efficiency with parasitic loads (from compressors, pumps, and cooling fans), system water balance, and component operating temperatures/pressures. Model results for a 5-kW fuel cell generator show that with state-of-the-art PEM fuel cell polarization curves, thermal efficiencies >30% can be achieved when power densities are low enough for operating voltages >0.72 V per cell. Efficiency can be increased by operating the reformer at steam-to-carbon ratios as high as constraints related to stable reactor temperatures allow. Decreasing ambient temperature improves system water balance and increases efficiency through parasitic load reduction. The baseline configuration studied herein sustained water balance for ambient temperatures ≤35 °C at full power and ≤44 °C at half power with efficiencies approaching ∼27 and ∼30%, respectively.

    Simpson, A K

    1984-01-01

    The US is the target for international migration, now more than ever. Population growth and economic stragnation in the Third World are increasing the pressures for out-migration, and current immigration law is wholly incapable of responding to the ever increasing flow of illegal immigrants. Border apprehensions of illegal aliens in the US were up 40% during 1983, and total apprehensions reached 1.25 million by the year's end. Recent public opinion polls have disclosed that an overwhelming majority of the American public demands immigration reform, and yet we as a nation have been distinctly unwilling or unable to respond to this clear public sentiment. This paper discusses the politics of the "Simpson-Mazzoli" Immigration Reform and Control Act, previous immigration legislation, current counterproposals for US immigration policy, and the political realities of immigration reform.

  14. Hot char-catalytic reforming of volatiles from MSW pyrolysis

    International Nuclear Information System (INIS)

    Wang, Na; Chen, Dezhen; Arena, Umberto; He, Pinjing

    2017-01-01

    Highlights: • Volatile from MSW pyrolysis is reformed with hot char from the same pyrolysis process. • The yields of syngas increase evidently with H 2 being the main contributor and the major component of the syngas. • Pyrolysis oil becomes light and its composition distribution is narrowed. • The HHV, volatile elements and alkali metals contents in the char decrease. • The emissions including SO 2 , NO, NO 2 and HCN changed after reforming process. - Abstract: Volatile products obtained from pyrolysis of municipal solid waste (MSW), including syngas and pyrolysis oil, were forced to contact the hot char from the same pyrolysis process at 500–600 °C in a fixed bed reactor to be reformed. The yields and properties of syngas, char and pyrolysis liquid were investigated; and the energy re-distribution among the products due to char reforming was quantified. The preliminary investigation at lab scale showed that hot char-catalytic reforming of the volatiles leads to an increase in the dry syngas yield from 0.25 to 0.37 N m 3 kg −1 MSW at 550 °C. Accordingly, the carbon conversion ratio into syngas increases from 29.6% to 35.0%; and the MSW chemical energy transferred into syngas increased from 41.8% to 47.4%. The yield of pyrolysis liquid products, including pyrolysis oil and water, decreased from 27.3 to 16.5 wt%, and the molecular weight of the oil becoming lighter. Approximately 60% of the water vapour contained in the volatiles converted into syngas. After reforming, the concentrations of SO 2 and HCN in the syngas decreases, while those of NO and NO 2 increase. The char concentrations of N, H, C and alkali metal species decreased and its higher heating value decreased too.

    2017-03-29

    Two novel routes for the production of gasoline from pyrolysis oil (from timber pine) and biogas (from ley grass) are simulated, followed by a cradle-to-gate life-cycle assessment of the two production routes. The main aim of this work is to conduct a holistic evaluation of the proposed routes and benchmark them against the conventional route of producing gasoline from natural gas. A previously commercialized method of synthesizing gasoline involves conversion of natural gas to syngas, which is further converted to methanol, and then as a last step, the methanol is converted to gasoline. In the new proposed routes, the syngas production step is different; syngas is produced from a mixture of pyrolysis oil and biogas in the following two ways: (i) autothermal reforming of pyrolysis oil and biogas, in which there are two reactions in one reactor (ATR) and (ii) steam reforming of pyrolysis oil and catalytic partial oxidation of biogas, in which there are separated but thermally coupled reactions and reactors (CR). The other two steps to produce methanol from syngas, and gasoline from methanol, remain the same. The purpose of this simulation is to have an ex-ante comparison of the performance of the new routes against a reference, in terms of energy and sustainability. Thus, at this stage of simulations, nonrigorous, equilibrium-based models have been used for reactors, which will give the best case conversions for each step. For the conventional production route, conversion and yield data available in the literature have been used, wherever available.The results of the process design showed that the second method (separate, but thermally coupled reforming) has a carbon efficiency of 0.53, compared to the conventional route (0.48), as well as the first route (0.40). The life-cycle assessment results revealed that the newly proposed processes have a clear advantage over the conventional process in some categories, particularly the global warming potential and primary

  5. Reforming birth registration law in England and Wales?

    Directory of Open Access Journals (Sweden)

    Julie McCandless

    2017-06-01

    Full Text Available The Law Commission of England and Wales is considering what its 13th Programme of Law Reform should address. During the consultation process, a project on birth registration law has been mooted. This is a very welcome proposal given that civil birth registration in England and Wales is a compulsory procedure that not only finds its roots in the early Victorian era, but also remains very similar, at least in terms of form and the information that is recorded. I first use two recent legal challenges to illustrate why the current system is coming under increasing pressure. I further use these examples to caution against a law reform agenda that is narrowly focused on the precise information recorded, without a preliminary and wider examination of what the role and purpose of birth registration is, and should be, in society. I argue that this needs to be addressed before the state can justify the parameters of the information recorded. I then use an outline of historical reforms relating to the registration of births outside of marriage to highlight the normative two-parent family model that underpins the birth registration system. I argue that legal reform must be cognizant of the tenacity of this normative family model, particularly in relation to reform proposals surrounding donor conception and the annotation of birth certificates. Finally, I draw attention to wider developments in family law that cast birth registration as a social policy tool for the facilitation of parent–child relationships, particularly unmarried fathers.

  6. Neo-Liberal Educational Reform in Latin America

    Directory of Open Access Journals (Sweden)

    Susana López Guerra

    2006-05-01

    Full Text Available Using the argument that educational systems in Latin American are inefficient, political organizations and international financial institutions promoted reforms based on free market principles to modernize education in the region. Chile was used as a laboratory for these reforms, which were then applied to other Latin American countries. This paper analyzes the argument that educational quality is improved through competition—used as a strategy to privatize the educational system—by transferring its financing from public to private sources, to the detriment of the national system of education. Finally, this paper examines the modernization process and the failure of the free market model of the Mexican system of education.

Demographic trends have a significant impact on social policies in each state and in particular on social security pensions. By 2050, the number of young active population will decrease dramatically. Meanwhile, the older population will triple. And so, the pension expenditure will increase and regarding this many countries reform they pension systems. Pension systems in the European Union are very different, due to the fact, that there is a tradition regarding the way that pensions are granted and the various phases of the reform process.

  19. Reforming Technologies to Improve the Performance of Combustion Systems

    Directory of Open Access Journals (Sweden)

    Hashim Hassan

    2014-09-01

    Full Text Available A large number of theoretical and experimental studies have shown that the performance of kerosene combustion increases significantly if combustion is being assisted by the addition of hydrogen to the fuel/air mixture during the combustion process. It reduces the amount of CO, CO2 and NOx emissions, while increasing the flame stability limits. It also helps in bruning fuel/air mixtures at much leaner equivalence ratios. The same principle could be applied to gain benefits in gas turbine combustors. Hydrogen for this purpose could be produced by the reforming of hydrocarbon fuels using a reformer module. This paper presents key hydrogen reforming technologies which, by implementation in gas turbine combustors, hold potential for improving both their performance and service life.

    2012-05-01

    The current Australian national maternity reform agenda focuses on improving access to maternity care for women and their families while preserving safety and quality. The caseload midwifery model of care offers the level of access to continuity of care proposed in the reforms however the introduction of these models in Australia continues to meet with strong resistance. In many places access to caseload midwifery care is offered as a token, usually restricted to well women, within limited metropolitan and regional facilities and where available, places for women are very small as a proportion of the total service provided. This case study outlines a major clinical redesign of midwifery care at a metropolitan tertiary referral maternity hospital in Sydney. Caseload midwifery care was introduced under randomised trial conditions to provide midwifery care to 1500 women of all risk resulting in half of the publicly insured women receiving midwifery group practice care. The paper describes the organisational quality and safety tools that were utilised to facilitate the process while discussing the factors that facilitated the process and the barriers that were encountered within the workforce, operational and political context.

  6. Electron-induced dry reforming of methane in a temperature-controlled dielectric barrier discharge reactor

    KAUST Repository

    Zhang, Xuming

    2013-09-23

    Dry reforming of methane has the potential to reduce the greenhouse gases methane and carbon dioxide and to generate hydrogen-rich syngas. In reforming methane, plasma-assisted reforming processes may have advantages over catalytic processes because they are free from coking and their response time for mobile applications is quick. Although plasma-assisted reforming techniques have seen recent developments, systematic studies that clarify the roles that electron-induced chemistry and thermo-chemistry play are needed for a full understanding of the mechanisms of plasma-assisted reformation. Here, we developed a temperature-controlled coaxial dielectric barrier discharge (DBD) apparatus to investigate the relative importance of electron-induced chemistry and thermo-chemistry in dry reforming of methane. In the tested background temperature range 297-773 K, electron-induced chemistry, as characterized by the physical properties of micro-discharges, was found to govern the conversions of CH4 and CO2, while thermo-chemistry influenced the product selectivities because they were found to depend on the background temperature. Comparisons with results from arc-jet reformation indicated that thermo-chemistry is an efficient conversion method. Our findings may improve designs of plasma-assisted reformers by using relatively hotter plasma sources. However, detailed chemical kinetic studies are needed. © 2013 IOP Publishing Ltd.

  7. Regulatory Reform as a Normative Concept: an Opportunity for the Development of Constitutive Policies

    Directory of Open Access Journals (Sweden)

    Ana Petek

    2008-01-01

    Full Text Available Regulatory reform, as part of public sector reform, concerns the change of the way of using regulation as a policy instrument. Since it started for the purpose of facilitating the operation of the business sector through simplifying the regulatory system in order to achieve increased competitiveness in the global market, it still has many opponents criticising its neoliberal background. This paper seeks to show how the regulatory reform programme has “transcended” its primary purpose because its reach has expanded even to noneconomic policy sectors – constitutive policies. Such broader interpretational framework of the objectives of regulatory reform allows access to the regulatory process for a much greater number of actors, particularly for noneconomic interest groups, and the benefits of the regulatory reform programme have spread among the broader ranks of the community. The implication of opening the regulatory process is an opportunity for other value systems, competing with neoliberalism, to affect regulatory reform. The paper especially emphasizes the governance approach to the research on regulatory reform, as the one which can outline and analyse its above-mentioned positive aspects. The essential thesis of the paper is that regulatory reform, as a specific normative concept, if understood within a broader interpretational framework, stimulates the development of constitutive policies in the sense that it places them higher on the policy priority scale of a regulatory state, and that this is exactly what should be the dominant logic of its introduction.

  8. The pension reform: foreign experience for Ukraine

    ; extending the period of insurance and contributions to pension funds of the country; changes in the procedure of the pension benefit indexation; encouraging the development of additional professional programs of funded pension schemes and personal pension insurance; increasing premiums and upgrading the base for their calculations. The issue of retirement age is the most painful for all EU countries, as it affects the interests of several generations, present and future pensioners. The general trend towards increasing the retirement age is influenced by a number of demographic, economic and social factors: increased life expectancy and its active period; limited manpower; possibility of employing the professional and intellectual potential of elderly staff; the need for  spreading out  the base of contributors for the pension budget increase; preventing the risk of the poverty expansion among pensioners; smoothing the gap in living standards of the employed and pensioners. For our country, like for most European countries, the problem of population aging and, consequently, increased demographic burden is one of the biggest problems. The aging process of the Ukrainian nation is characterized by the rapid growth of the number of people aged over 60 years. According to demographic projections for 2026, their share will increase to 25%. In this situation, the only solution is to reform the pension system of Ukraine. It would be reasonable to adopt the European system of pension insurance as an example. Conclusions of the research. For our country, further study of the European experience and successful workable solutions will be useful with regard to their application in the process of building and reforming own pension systems, thus avoiding the negative trends caused by socio-economic realities of modern society.

  9. The new institutionalist approaches to health care reform: lessons from reform experiences in Central Europe.

    Science.gov (United States)

    Sitek, Michał

    2010-08-01

    This article discusses the applicability of the new institutionalism to the politics of health care reform in postcommunist Central Europe. The transition to a market economy and democracy after the fall of communism has apparently strengthened the institutional approaches. The differences in performance of transition economies have been critical to the growing understanding of the importance of institutions that foster democracy, provide security of property rights, help enforce contracts, and stimulate entrepreneurship. From a theoretical perspective, however, applying the new institutionalist approaches has been problematic. The transitional health care reform exposes very well some inherent weaknesses of existing analytic frameworks for explaining the nature and mechanisms of institutional change. The postcommunist era in Central Europe has been marked by spectacular and unprecedented radical changes, in which the capitalist system was rebuilt in a short span of time and the institutions of democracy became consolidated. Broad changes to welfare state programs were instituted as well. However, the actual results of the reform processes represent a mix of change and continuity, which is a challenge for the theories of institutional change.

    Three broad strategies for health financing reform include: 1) cost recovery through user fees to expand access and improve quality of health services along with means testing to increase equity; 2) reallocation of existing resources to improve efficiency and access; and 3) assessment of the efficiency and quality of private health providers for making better use of the private sector in expanding access to quality health services. Research on the extent to which cost recovery reforms have improved access showed mixed results. A 1993 survey of more than 50 user fee experiences in Africa showed that in roughly half the cases, utilization either remained the same or decreased, whereas in the other cases, utilization increased after fees were introduced. Pilot tests of alternative cost recovery methods in 1993 and 1994 in rural Niger provided strong evidence that some form of social financing or risk-sharing mechanism may have advantages over pure fee-for-service methods in rural Africa. The main reason user fees are believed to be inequitable is that new or increased prices may provide a stronger disincentive to the poor than to the better-off. Informal means testing in Niger suggested that even moderately effective means testing can play a positive role for other incentives to utilization by the poor. A study identified specific measures of structure, process, and outcomes to assess quality improvement in 18 rural primary health care facilities involved in the Niger cost recovery pilot tests. Reallocation of existing resources to improve cost-effectiveness represents the second principle type of health financing reform. Private providers also play a role in promoting access in Sub-Saharan countries. Public and private sector efficiency in Senegal was also examined. Household spending to promote efficiency suggested that people could allocate money for health care more efficiently. Finally, some policy research needs were identified.

  1. The Brazilian electrical system reform

    International Nuclear Information System (INIS)

    Mendonca, A.F.; Dahl, C.

    1999-01-01

    Although the Brazilian electrical system has been a public monopoly, the threat of electricity shortages from a lack of investment triggered a comprehensive reform. In 1993 the government began a series of laws, decrees and regulations reforming the tariff policy, allowing privatization of utilities, foreign investments and independent power producers, and creating an independent transmission grid and a new electricity regulatory agency (ANEEL). The new regulatory framework is not completely defined but the proposed model intends to transform bulk electricity supply into a competitive market similar to that adopted in England. Our objective is to evaluate whether the proposed reform will succeed in attracting the required private capital, will allow an unregulated wholesale electricity market and will require a strict regulatory framework. The reform has been quite successful in privatizing the distribution companies but is allowing monopolistic rents, and has failed until now to attract private investments to expand generation capacity. The risk of blackouts has increased, and the proposed wholesale electricity market may not be appropriate because of barriers to constructing new hydroelectric units, now 90% of the system. Therefore, a new regulatory framework and a strong regulatory agency with a well-defined tariff policy should have preceded the privatization. (author)

    Making substantial changes to the form and delivery of medical education is challenging. One reason for this may be misalignment between existing conceptualizations of curricula and curriculum reform in medical education, with the former perceived as 'complex' yet the latter as linear. Reframing curriculum reform as a process-driven, complex entity may enhance the possibility of change. To explore the utility of this approach, we carried out an exploratory case study of curriculum reform in a real-life context. We used a qualitative case study approach. Data were collected from 17 interviews with senior faculty involved in curriculum reform in one medical school plus document analysis of approximately 50 documents and files, to provide background, context, and aid triangulation. Data coding and analysis was initially inductive, using thematic analysis. After themes were identified, we applied the 'wicked problem' framework to highlight aspects of the data. This paper focuses on two main analytic themes. First, that multiple players hold different views and values in relation to curriculum reform, resulting in various influences on the process and outcomes of reform. Second, 'solutions' generate consequences which go beyond the anticipated advantages of curriculum reform. This is the first empirical study of curriculum reform in medical education which uses the wicked problem framework to conceptually illuminate the complex processes which occur in relation to reform. Those involved in reform must be reflective and attentive to the possibility that persistent and emerging challenges may be a result of wicked problems.

  3. Public Benefits and Power Sector Reform. Report from an International Workshop

    2003-10-01

    The Workshop on Public Benefits and Power Sector Reform was motivated by the need to address broader development goals and advance the provision of public benefits in power sector reforms. The primary objectives were: To provide a forum for a discussion among specialists, of how the provision of public benefits can be expanded as power sectors in developing countries are reformed, and review the experience (Day 1). To identify the needs for training and capacity building and institutional arrangements, as well as make recommendations for their design and implementation, for policy makers, regulators, and other professionals in developing countries (Day 2). Public benefits is a socially constructed concept that includes activities that are not adequately conceived by competitive markets. Public benefit policies and programmes include those that expand electricity access to rural areas and the urban poor, improve security of supply, promote energy efficiency and renewable energy, etc. Reforms have indeed been a threat to public benefits as traditionally delivered through electric utilities. However, in many cases public benefit programmes have also been rescued. In fewer cases, public benefit programmes have been conceived in the reform process. From experience so far it is clear that power sector reforms must be made more compatible with broader sustainable development goals. Recognising the need for broader policy integration and putting public benefits higher on the reform agenda points to the importance of reaching beyond energy ministries and power sector experts at an early stage in the reform process. Other actors, such as NGOs and academia, may also be instrumental in monitoring and assessing the impacts of reform. Public benefits can be an integral part of a reform package, or a complement to reform. It does appear that reform creates space and opportunity to achieve public benefits, but someone has to utilise that opportunity. The need to make trade

    In this article, the authors present data from a small study of 19 families who educate their children at home in rural Pennsylvania. Findings relative to why they opted out of the public education system and whether they would return are analyzed in light of a previously established construct (Idealogue/Pedagogue before being used to critique and expand it in light of broader cultural concerns. The authors argue, overall, that home educators are asserting their historical option of cultural agency and schooling. (Note 1

    If "school reform" is a bandwagon, then the parade is still in progress. Most of the grand proposals earlier composed by politicians, pundits, policy wonks, and professors have evolved into smaller, more locally pertinent endeavors by actual change participants (educators, students, parents and community members. In the worst case, the continuing accumulation of school reform efforts is understood as succeeding waves of perpetual hassle and silliness which disturb the basic soundness of business-as-usual. In the best case, such efforts become a representation of participants' commitment to the repetitive nature of the learning process: desiring to know and understand - acting upon these desires - making sense of and reflecting upon those actions - identifying new or different desires to know and understand. Thus, in the best case, school reform efforts should be here to stay.

    Those who care about examining and acting upon the quality of their local schools seek information from numerous sources, including their own experiences, outside consultants, beliefs and opinions collected from local, state, and national polls, and "the literature" of academia. But they seldom tap the one segment of their community which may provide the most unique perspective: parents who have opted out of the local public school system. We suspect that this group -- particularly those families who have taken it upon themselves to provide

    Production of hydrogen from acetic acid (HAc) was performed by using a novel electrochemical catalytic reforming (ECR) approach over the 18%NiO/Al{sub 2}O{sub 3} catalyst. ECR was carried out in a fixed-bed continuous flow reactor, where an ac electric current was passed through the catalyst. A high yield of hydrogen (>90%) and carbon conversion (>90%) were obtained as the reforming temperature over 400 C via the ECR approach. The influences of the current on the HAc decomposition, its reforming, and the catalyst reduction in the ECR process have been investigated, which were compared with those in the common steam reforming (CSR) route. The mechanism of the HAc reforming in ECR was also discussed based on the present investigation. (author)

  7. A cross-country analysis of electricity market reforms: Potential contribution of New Institutional Economics

    Erdogdu, Erkan

    2013-01-01

    The paper explores whether the question of why some countries are able to implement more extensive reforms is closely related to the question of why some countries have better institutions than others. We analyze this question by using an empirical econometric model based on Poisson regression with cross-section data covering 51 states in the US, 13 provinces in Canada and 51 other countries. In the course of the study, we check the validity of three important arguments of New Institutional Economics (NIE) for the power market liberalization process. The first argument is the “path-dependency”. To test its impact on the reform progress, we try to explain whether the background of the chairperson of the regulatory agency when reforms started or that of the governor/minister responsible for energy policy at that time has an impact on the subsequent reform progress. The second argument is the impact of “democracy” as an institution on the reform progress. We look at the effect of two important indicators of democracy (i.e., civil liberties and political rights) on the reform progress. The final argument of NIE is about transaction costs. We concentrate on the level of corruption in a country as one of the key factors that determine transaction costs and try to explore its impact on the reforms. The results show that the backgrounds of the chairperson and the minister/governor, the level of democracy and corruption in a country are significantly correlated with how far reforms have gone in that country. The negative relationship between reform progress and civil liberties may indicate that reforms may be limited in democratic countries with strong civil society institutions such as trade unions or other organized structures in the society that may consider reforms as ‘harmful’ to their self-interest. - Highlights: • We model impact of institutions on the electricity market reforms. • Dataset covers 51 states in the US, 13 provinces in Canada and 51

    The Chilean health care system has been intensively reformed in the past 20 years. Reforms under the Pinochet government (1973-1990) aimed mainly at the decentralization of the system and the development of a private sector. Decentralization involved both a deconcentration process and the devolution of primary health care to municipalities. The democratic governments after 1990 chose to preserve the core organization but introduced reforms intended to correct the system's failures and to incr...

In this context, the underlying physical sintering mechanism and quantitative information about the rate of sintering at industrial conditions are relevant....... In this paper, particle migration and coalescence in nickel steam reforming catalysts is studied. Density functional theory calculations indicate that Ni-OH dominate nickel transport at nickel surfaces in the presence of steam and hydrogen as Ni-OH has the lowest combined energies of formation and diffusion...... compared to other potential nickel transport species. The relation between experimental catalyst sintering data and the effective mass diffusion constant for Ni-OH is established by numerical modelling of the particle migration and coalescence process.

    Hydrogen production from glycerol by steam reforming combine two major advantages: (i) using glycerol as raw material add value to this by product of bio-diesel production which is obtained in large quantities around the world and have a very limited utilization now, and (ii) by implication of water molecules in the reaction the efficiency of hydrogen generation is increased as each mol of glycerol produces 7 mol of H 2 . In this work we present the results obtained in the process of steam reforming of glycerol on Ni/Al 2 O 3 . The catalyst was prepared by wet impregnation method and characterized through different methods: N 2 adsorption-desorption, XRD, TPR. The catalytic study was performed in a stainless steel tubular reactor at atmospheric pressure by varying the reaction conditions: steam/carbon ratio (1-9), gas flow (35 ml/min -133 ml/min), temperature (450-650°C). The gaseous fraction of the reaction products contain: H 2 , CH 4 , CO, CO 2 . The optimum reaction conditions as resulted from this study are: temperature 550°C, Gly:H 2 O ratio 9:1 and Ar flow 133 ml/min. In these conditions the glycerol conversion to gaseous products was 43% and the hydrogen yield was 30%

    Full Text Available This paper considers the social and structural policies in contemporary Europe. The presentation is organized in four sections. First, we discuss the emerging Europe, the new unity based on democracy and the market economy, the special European Union formula, and comparisons with America. Second, we analyze the dynamics of the European economy, the convergence process, the gaps between United States in productivity and standard of living, competitiveness issues, and the emergence of a new European economy and new European policy mix.Third, we consider European social conditions, the stationary and aging population, Europe’s low employment rate and permanently high unemployment. European economic growth could draw on two major sources: the labor reserves and reforms in factor, product and service markets. In a monetary union, advanced industrial relations should promote labor mobility and salary flexibility. The social security systems permit the redistribution and cohesion which defines the European model.Fourth, for the new Europe, the structural reform strategy is the way forward for the challenge of European economic policy and social policy: more and better jobs thanks to sustainable growth in a dynamic and competitive knowledge-based economy, favoring greater social cohesion.

    Full Text Available This article analyses the role of the main international actors involved in the implementation of police reform in post-conflict Bosnia and Herzegovina, notably that of the UN and the EU. Despite considerable efforts and resources deployed over 17 years, the implementation of police reform remains an ‘unfinished business’ that demonstrates the slow pace of implementing rule of law reforms in Bosnia’s post-conflict setting, yet, in the long-term, remains vital for Bosnia’s stability and post-conflict reconstruction process. Starting with a presentation of the status of the police before and after the conflict, UN reforms (1995–2002 are first discussed in order to set the stage for an analysis of the role of the EU in the implementation of police reform. Here, particular emphasis is placed on the institution-building actions of the EU police mission in Bosnia and Herzegovina deployed on the ground for almost a decade (2003-June 2012. The article concludes with an overall assessment of UN and EU efforts in post-conflict Bosnia and Herzegovina, including the remaining challenges encountered by the EU on the ground, as the current leader to police reform implementation efforts. More generally, the article highlights that for police reform to succeed in the long-term, from 2012-onwards, the EU should pay particular attention to the political level, where most of the stumbling blocks for the implementation of police reform lie.

  16. Energy efficiency of a direct-injection internal combustion engine with high-pressure methanol steam reforming

    Poran, Arnon; Tartakovsky, Leonid

    2015-01-01

    This article discusses the concept of a direct-injection ICE (internal combustion engine) with thermo-chemical recuperation realized through SRM (steam reforming of methanol). It is shown that the energy required to compress the reformate gas prior to its injection into the cylinder is substantial and has to be accounted for. Results of the analysis prove that the method of reformate direct-injection is unviable when the reforming is carried-out under atmospheric pressure. To reduce the energy penalty resulted from the gas compression, it is suggested to implement a high-pressure reforming process. Effects of the injection timing and the injector's flow area on the ICE-SRM system's fuel conversion efficiency are studied. The significance of cooling the reforming products prior to their injection into the engine-cylinder is demonstrated. We show that a direct-injection ICE with high-pressure SRM is feasible and provides a potential for significant efficiency improvement. Development of injectors with greater flow area shall contribute to further efficiency improvements. - Highlights: • Energy needed to compress the reformate is substantial and has to be accounted for. • Reformate direct-injection is unviable if reforming is done at atmospheric pressure. • Direct-injection engine with high-pressure methanol reforming is feasible. • Efficiency improvement by 12–14% compared with a gasoline-fed engine was shown

    Under DOE Contract No. DE-AR21-95MC32091, Steam Reforming of Low-Level Mixed Waste, ThermoChem has successfully designed, fabricated and operated a nominal 90 pound per hour Process Development Unit (PDU) on various low-level mixed waste surrogates. The design construction, and testing of the PDU as well as performance and economic projections for a 500- lb/hr demonstration and commercial system are described. The overall system offers an environmentally safe, non-incinerating, cost-effective, and publicly acceptable method of processing LLMW. The steam-reforming technology was ranked the No. 1 non-incineration technology for destruction of hazardous organic wastes in a study commissioned by the Mixed Waste Focus Area published April 1997.1 The ThermoChem steam-reforming system has been developed over the last 13 years culminating in this successful test campaign on LLMW surrogates. Six surrogates were successfidly tested including a 750-hour test on material simulating a PCB- and Uranium- contaminated solid waste found at the Portsmouth Gaseous Diffusion Plant. The test results indicated essentially total (>99.9999oA) destruction of RCRA and TSCA hazardous halogenated organics, significant levels of volume reduction (> 400 to 1), and retention of radlonuclides in the volume-reduced solids. Cost studies have shown the steam-reforming system to be very cost competitive with more conventional and other emerging technologies.

  18. Czech Public and Occupational Pension Schemes and Reforms

    Directory of Open Access Journals (Sweden)

    VOSTATEK, Jaroslav

    2017-08-01

    Full Text Available The Czechoslovak communist retirement protection scheme resembled the Bismarckian earnings-related pensions, with new benefits close to final salaries and with their insufficient indexation. The aim of this paper is to evaluate the reform processes in Czechia and the potential for a simple technical reform that would make the public retirement schemes understandable and efficient. In the process of the transition to capitalism under liberal Czech governments, the prevailing concept of the public retirement scheme changed to a Beveridge model of pensions not being related to previous wages. The insufficient valorisation of bend points was the main method of this transition. Modern international pension theory recommends the separation of a solidary pillar and an earnings-related pillar. After the Czech “small” pension reform, a basic technical reform may be simply realised, resulting in a higher flat-rate pension and an NDC pension insurance scheme, convenient to parties with programmes based on three basic welfare regimes. The introduction of occupational pension schemes is necessary to reflect the specifics of arduous occupations.

    IFP and HyRadix are collaborating in the development of a new hydrogen production system from liquid feedstock such as bio-ethanol. Reducing greenhouse gas (GHG) emissions along with high hydrogen yield are the key objectives. Market application of the system will be hydrogen refueling stations as well as medium scale hydrogen consumers including the electronics, metals processing, and oils hydrogenation industries. The conversion of bio-ethanol to hydrogen will be performed within a co-developed process including an auto-thermal reformer working under pressure. The technology will produce high-purity hydrogen with ultralow CO content. The catalytic auto-thermal reforming technology combines the exothermic and endothermic reaction and leads to a highly efficient heat integration. The development strategy to reach a high hydrogen yield target with the bio-ethanol hydrogen generator is presented. (authors)

    2017-01-01

    This paper presents a cross-country benchmarking study of natural gas distribution to final consumers and compares two samples of companies in Italy and Ukraine. A 2-stage DEA procedure calculating efficiency of gas providers and identifying critical context factors and policy issues that affect it is implemented. Both countries are low performing in terms of operators’ technical and scale efficiency and there is room to design more efficient market configurations. Some issues need attention to develop an effective gas market policy: a) search for efficiency requires accurate investigation of its main drivers that depend on context factors; b) while greater efficiency is necessary to reduce cost and increase service quality, at different stages of progress of the reform process other goals may be more important; c) gas industry reform process should be planned adopting a systemic perspective as its development does not remain confined to the sector, but implies changes in the whole country economy, particularly when the gas market is of primary relevance to the economy; d) a more comprehensive package of reforms may be necessary to make gas market reform successful; e) even though the gas market reform is an economic process, it has unavoidably social and political implications. - Highlights: • Benchmarking of natural gas distribution industry in Italy and Ukraine is performed. • Average industry inefficiency is about 27% and decreasing returns to scale are dominant. • Gas industry reform process should be planned adopting a systemic perspective. • Gas reform needs a more comprehensive package of reforms and/or supporting legislation to be successful. • Gas industry reform has social and political implications.

    Using a dynamic general equilibrium model, we explore the role of habit formation when analyzing green tax reforms under the double dividend hypothesis. We assume increases in energy taxes and adjust capital taxation in a revenue-neutral framework to evaluate the effects on welfare. Since the existence of an environmental dividend is uncontroversial, we mainly focus on the efficiency dividend. Our findings show that, when taxes on household energy consumption increase, habits and transitional dynamics alter household decisions, and change the efficiency dividend. However, when the tax increase is on energy used as an input, reform always induces a welfare cost in terms of efficiency. In this case, habits play a less important role. (author)

Healthcare reform must eventually ask not only how do we pay for healthcare and how do we distribute it, but more fundamentally, what kind of healthcare do we want? It must ask, in short, what are the goals of medicine? Yet, even though narrative medicine is crucial to answering these pivotal and inescapable questions, it is not easy to describe. Many of its core claims go against the grain of common sense thinking about medicine. This article argues that the best way to understand narrative medicine is to tell a story that puts its emergence in historical context.

    Since 1998 Denmark has been in a process of re-regulating its energy market introducing competition and incentive based economic regulation. The ''Danish model'' reflects specific Danish political priorities on energy, environment and the role of the energy consumers. The paper focuses on the electricity sector, tracing the reasons why Denmark re-regulates the way it does and what are the results. Denmark is a small country of 43000 2 kilometers and 5.3 million inhabitants. Denmark is a net-exporter of oil and gas produced in the North Sea. The hydro-resources are negligible. Renewable energy, however, covers 11 percent of gross energy consumption.(author)

  8. The california electricity reform debacle

    Jaccard, M.

    2001-01-01

    In 1998, California launched a dramatic reform of its electricity sector, vertically de-integrating its major utilities and establishing a competitive generation market, with separate entities responsible for grid control and power exchange. After two uneventful years, wholesale prices rose dramatically in the summer of 2000 and have remained high into 2001. An imbalance between the high wholesale prices and frozen retail rates caused a financial crisis for the electric utilities and power shortages have been a chronic threat. Several factors contributed to this crisis: capacity has not expanded in step with demand either in California or its larger trading region; extreme weather and poorly timed plant outages further increased demand and decreased supply; market design flaws allowed significant suppliers to influence the market while frozen retail rates limited the demand response that would have mitigated the supply-demand imbalance. State and federal agencies have taken corrective action but the situation may remain critical for some time. Longer term solutions involve recognizing the special characteristics of electricity in designing marking reform. Because electricity supply and demand must be instantaneously balanced at all times, market reform must ensure that someone has the responsibility and effective tools to ensure that this occurs, in spite of unforeseen circumstances, and to prevent the exercise of market power. Because a competitive commodity market must work in concert with a monopoly delivery system, someone must be responsible and have the means to develop and operate the grid in ways that are amenable to effective competition. Finally, reform design must ensure that the cyclical investment and price patterns of normal commodity markets are minimized in the electricity market and that when they do occur, market volatility does not compromise reliability and price stability for those who value these highly and would pay a premium for them

  9. Data reconciliation and optimal operation of a Catalytic naphtha reformer

    Full Text Available The naphtha reforming process converts low-octane gasoline blending components to high-octane components for use in high-performance gasoline fuels. The reformer also has an important function as the producer of hydrogen to the refinery hydrotreaters. A process model based on a unit model structure, is used for estimation of the process condition using data reconciliation. Measurements are classified as redundant or non redundant and the model variables are classified as observable, barely observable or unobservable. The computed uncertainty of the measured and unmeasured variables shows that even if a variable is observable it may have a very large uncertainty and may thereby be practically unobservable. The process condition at 21 data points, sampled from two years of operation, was reconciled and used to optimize the process operation. There are large seasonal variations in the reformer product price and two operational cases are studied. In case 1, the product price is high and throughput is maximized with respect to process and product quality constraints. In case 2, the product price is low and the throughput is minimized with respect to a low constraint on the hydrogen production. Based on the characteristics of the optimal operation, a "self optimizing" control structure is suggested for each of the two operational cases.

    Catalytic steam reforming of bio-oil is a promising process for producing hydrogen in a sustainable environmentally friendly way that can improve the utilization of local resources (natural sources or wastes). However, there remain drawbacks such as coke formation that produce operational problems and deactivation of the catalysts. Coprecipitated Ni/Al catalysts are here used in a fluidized bed for reforming at 650 C of acetic acid as a model compound of bio-oil-aqueous fraction. Different strategies are applied in order to study their effects on the catalytic steam reforming process: modification of the catalyst by increasing the calcination temperature or adding promoters such as calcium. The addition of small quantities of oxygen is also tested resulting in an optimum percentage to achieve a high carbon conversion process with less coke and without a hydrogen yield penalty production. The results for catalytic steam reforming are compared with other ones from literature. (author)

  11. Solar Reforming of Carbon Dioxide to Produce Diesel Fuel

    2010-12-31

    This project focused on the demonstration of an innovative technology, referred to as the Sunexus CO2 Solar Reformer, which utilizes waste CO2 as a feedstock for the efficient and economical production of synthetic diesel fuel using solar thermal energy as the primary energy input. The Sunexus technology employs a two stage process for the conversion of CO2 to diesel fuel. A solar reforming system, including a specially designed reactor and proprietary CO2 reforming catalyst, was developed and used to convert captured CO2 rich gas streams into syngas (primarily hydrogen and carbon monoxide) using concentrated solar energy at high conversion efficiencies. The second stage of the system (which has been demonstrated under other funding) involves the direct conversion of the syngas into synthetic diesel fuel using a proprietary catalyst (Terra) previously developed and validated by Pacific Renewable Fuels and Chemicals (PRFC). The overall system energy efficiency for conversion of CO2 to diesel fuel is 74%, due to the use of solar energy. The results herein describe modeling, design, construction, and testing of the Sunexus CO2 Solar Reformer. Extensive parametric testing of the solar reformer and candidate catalysts was conducted and chemical kinetic models were developed. Laboratory testing of the Solar Reformer was successfully completed using various gas mixtures, temperatures, and gas flow rates/space velocities to establish performance metrics which can be employed for the design of commercial plants. A variety of laboratory tests were conducted including dry reforming (CO2 and CH{sub 4}), combination dry/steam reforming (CO2, CH{sub 4} & H{sub 2}O), and tri-reforming (CO2, CH{sub 4}, H{sub 2}O & O{sub 2}). CH{sub 4} and CO2 conversions averaged 95-100% and 50-90% per reformer cycle, respectively, depending upon the temperatures and gas space velocities. No formation of carbon deposits (coking) on the catalyst was observed in any of these tests. A 16 ft. diameter

    Full Text Available Analyzing process of political reforms in the People's Republic of China, the author notes that within the first 20 years of reforms and openness of China economic growth wasn't followed by development of society, political reforms didn't keep up for economic, imperfection of political system constrained economic reforms and development. Owing to this fact the XVI congress of a CPC lifted policy to the level of "political culture" by analogy with "material culture" and "spiritual culture". In the first 20 anniversary of the XXI century with the purpose to finish "comprehensive creation of society "of small prosperity" China has to create "perfect system of socialist market economy", construct "harmonious socialist society". For achievement of these purposes political reforms in China have to provide "improvement of socialist democracy" and "the socialist constitutional state". In the first years of the XXI century they brought a number of significant achievements: political stability, peaceful alternation of generations of the power, essential increase of level of political democracy. The first stage of formation of the constitutional socialist state is passed, ability and level of the management from ruling party increased; party construction amplified. But also at the beginning of the second decade of the XXI century implementation of the legislation, democracy faces many calls, especially intensification of nationalism at the beginning of the century. The Chinese dream will mobilize grandiose powers of unity that China deepened reforms and openness, solved all the political problems, helped a CPC to increase the leading and imperious power. Implementation process of "The Chinese dream" also means aspiration to tops of economy, policy, military science, technologies in the world, to a taking them, reflecting process of formation of the new great power which will succeed the USA.

    Pickett, Derek Kyle

    Due to an increased interest in sustainable energy, biodiesel has become much more widely used in the last several years. Glycerin, one major waste component in biodiesel production, can be converted into a hydrogen rich synthesis gas to be used in an engine generator to recover energy from the biodiesel production process. This thesis contains information detailing the production, testing, and analysis of a unique synthesis generator rig at the University of Kansas. Chapter 2 gives a complete background of all major components, as well as how they are operated. In addition to component descriptions, methods for operating the system on pure propane, reformed propane, reformed glycerin along with the methodology of data acquisition is described. This chapter will serve as a complete operating manual for future students to continue research on the project. Chapter 3 details the literature review that was completed to better understand fuel reforming of propane and glycerin. This chapter also describes the numerical model produced to estimate the species produced during reformation activities. The model was applied to propane reformation in a proof of concept and calibration test before moving to glycerin reformation and its subsequent combustion. Chapter 4 first describes the efforts to apply the numerical model to glycerin using the calibration tools from propane reformation. It then discusses catalytic material preparation and glycerin reformation tests. Gas chromatography analysis of the reformer effluent was completed to compare to theoretical values from the numerical model. Finally, combustion of reformed glycerin was completed for power generation. Tests were completed to compare emissions from syngas combustion and propane combustion.

    China's Reform and Open up Policy in 1980s has brought rapid economic development to Chinese society. With the deepening of economic reform, the withdrawal of the state in China has had visible and worrisome consequences for health and for the functioning of health services. The new round of healthcare reform after 2009 has made significant achievements on improving fundamental health and bringing back the nature of welfare of health. However, the financing mechanism of health system has not been established, and the underlying reason behind the healthcare reform dilemma and the theoretical solution need to be found. This study used the methods of literature review, theoretical research and comparative research to summarize and analyze the reasons and solutions of current dilemma in healthcare reform, and created the new discipline of health fiscalogy through theoretical analysis and vertical and horizontal comparison of healthcare system, especially health financing. Dilemma in healthcare system emerged from the circumstances of rapid process of industrialization, urbanization and population aging, including the profit-driven phenomena, tendency of excessive marketization in public hospitals, strained doctor-patient relationship, high disease burden on individuals and families, and so on. It can be concluded that the theoretical basis of healthcare system and the nature of health resources are crucial in solving the dilemma of healthcare reform. The theoretical basis of healthcare reform should be health fiscalogy focusing on government as the main body of health care responsibility rather than health economics focusing on anti-monopoly. There are two key differences between health economics and health fiscalogy: responsible person/department of disease and health welfare, and nature of resource. The new discipline of health fiscalogy has universal and important implications on both China's healthcare reform and the healthcare reform in the world. China

    Methanol production process configurations based on renewable energy sources have been designed. The processes were analyzed in the thermodynamic process simulation tool DNA. The syngas used for the catalytic methanol production was produced by gasification of biomass, electrolysis of water, CO 2 from post-combustion capture and autothermal reforming of natural gas or biogas. Underground gas storage of hydrogen and oxygen was used in connection with the electrolysis to enable the electrolyser to follow the variations in the power produced by renewables. Six plant configurations, each with a different syngas production method, were compared. The plants achieve methanol exergy efficiencies of 59-72%, the best from a configuration incorporating autothermal reforming of biogas and electrolysis of water for syngas production. The different processes in the plants are highly heat integrated, and the low-temperature waste heat is used for district heat production. This results in high total energy efficiencies (∼90%) for the plants. The specific methanol costs for the six plants are in the range 11.8-25.3 Euro /GJ exergy . The lowest cost is obtained by a plant using electrolysis of water, gasification of biomass and autothermal reforming of natural gas for syngas production.

    This paper/plenary lecture to this green energy conference briefly discusses six main issues: 1) The future of hydrogen economy; 2) Thermo-chemistry of hydrogen production for different techniques of autothermic operation using different feedstocks; 3) Improvement of the hydrogen yield and minimization of reformer size through combining fast fluidization with hydrogen and oxygen membranes together with CO 2 sequestration; 4) Efficient production of hydrogen using novel Autothermal Circulating Fluidized Bed Membrane Reformer (ACFBMR); 5) Economics of hydrogen production; and, 6) Novel gasification process for hydrogen production from biomass. It is shown that hydrogen economy is not a Myth as some people advocate, and that with well-directed research it will represent a bright future for humanity utilizing such a clean, everlasting fuel, which is also free of deadly conflicts for the control of energy sources. It is shown that autothermic production of hydrogen using novel reformers configurations and wide range of feedstocks is a very promising route towards achieving a successful hydrogen economy. A novel process for the production of hydrogen from different renewable biomass sources is presented and discussed. The process combines the principles of pyrolysis with the simultaneous use of catalyst, membranes and CO 2 sequestration to produce pure hydrogen directly from the unit. Some of the novel processes presented are essential components of modern bio-refineries. (author)

  18. Reforming health care in Canada: current issues

    Directory of Open Access Journals (Sweden)

    Baris Enis

    1998-01-01

    Full Text Available This paper examines the current health care reform issues in Canada. The provincial health insurance plans of the 1960s and 1970s had the untoward effects of limiting the federal government's clout for cost control and of promoting a system centered on inpatient and medical care. Recently, several provincial commissions reported that the current governance structures and management processes are outmoded in light of new knowledge, new fiscal realities and the evolution of power among stake-holders. They recommend decentralized governance and restructuring for better management and more citizen participation. Although Canada's health care system remains committed to safeguarding its guiding principles, the balance of power may be shifting from providers to citizens and "technocrats". Also, all provinces are likely to increase their pressure on physicians by means of salary caps, by exploring payment methods such as capitation, limiting access to costly technology, and by demanding practice changes based on evidence of cost-effectiveness.

    The transition to a cleaner and more cost-efficient electricity system in China is political-economic as well as technological. An example is the reform of China's method of dispatching power plants, which potentially affects the economic relationships between consumers and producers, between grid and generating companies, and between central and provincial governments. Historically, coal-fired power plants in China all received roughly the same number of operating hours, regardless of efficiency or cost. In 2007, Chinese government agencies began to pilot “energy efficient dispatch,” which requires that generators be dispatched on the basis of thermal efficiency. Using a case study of Guangxi Zhuang Autonomous Region in southern China, we evaluated potential energy and cost savings from a change to energy efficient dispatch. We found that the savings are at best relatively small, because large, efficient generators already account for a significant share of total generation. Moreover, as an administrative policy that does not change economic incentives, energy efficient dispatch exacerbates imbalances and center-provincial tensions in the current system. We argue that incentive-based dispatch reform is likely to produce better outcomes, and that the keys to this reform are empowering an independent regulator with pricing authority and establishing a formal, transparent ratemaking process. - Highlights: ► Savings from China's energy efficient dispatch (EED) policy are at best relatively small. ► EED exacerbates imbalances and center-provincial tensions in China's current power system. ► Incentive-based dispatch reform is likely to produce better outcomes than EED. ► Keys to reform are independent regulation and a formal, transparent ratemaking process. ► Transition to cleaner, cost-efficient electricity system in China is political-economic as well as technological.

    Objective China launched new healthcare reforms in 2009 and several policies targeted village clinics, which affected village doctors' income, training and duties. The aim of the present study was to assess village doctors' job satisfaction during the reforms and to explore factors affecting job satisfaction. Methods Using a stratified multistage cluster sampling process, 935 village doctors in Jiangxi Province were surveyed with a self-administered questionnaire that collected demographic information and contained a job satisfaction scale and questions regarding their work situation and individual perceptions of the new healthcare reforms. Descriptive analysis, Pearson's Chi-squared test and binary logistic regression were used to identify village doctors' job satisfaction and the factors associated with their job satisfaction. Results Only 12.72% of village doctors were either satisfied or very satisfied with their jobs and the top three items leading to dissatisfaction were pay and the amount of work that had to be done, opportunities for job promotion and work conditions. Marriage, income, intention to leave, satisfaction with learning and training, social status, relationship with patients and satisfaction with the new healthcare reforms were significantly associated with job satisfaction (Pjob satisfaction. For future healthcare reforms, policy makers should pay more attention to appropriate remuneration and approaches that incentivise village doctors to achieve the goals of the health reforms. What is known about the topic? Village doctors act as gatekeepers at the bottom tier of the rural health system. However, the policies of the new healthcare reform initiatives in China were centred on improving the quality of care delivered to the rural population and reducing fast-growing medical costs. There have been limited studies on village doctors' reactions to these reforms. What does this paper add? The findings of the present study indicate that in the

    2009-01-01

    The creation of the Energy Community of South Eastern Europe in 2005 committed countries in South Eastern Europe to liberalize their energy markets in accordance to EU regulations. The Government of Montenegro is thus in the process of reforming its energy sector, which includes an electricity tariff reform. This paper analyzes the environmental and social impacts of an increase in residential electricity tariffs contemplated - which is expected to range anywhere from 40 to over 100% increase. As this analysis shows, such a significant price rise will impose a heavy burden on the poor households and it may adversely affect the environment. In an ex ante investigation of the welfare impact of this price increase on households in Montenegro, we show that the anticipated price increase will result in a very significant increase in households' energy expenditures. A simulation of alternative policy measures analyzes the impact of different tariff levels and structures, focusing on the poor and vulnerable households. Higher electricity prices could also significantly increase the proportion of households using fuelwood for space heating. Thus the level of fuelwood consumption should be carefully monitored under the electricity tariff reforms and the Government of Montenegro should combine the tariff reforms with a carefully evaluated set of policy measures to mitigate the effect of the electricity price increase on the poor.

    Despite having achieved an average life expectancy of 75 years, much the same as that of more developed countries, Mexico entered the 21st century with a health system marred by its failure to offer financial protection in health to more than half of its citizens; this was both a result and a cause of the social inequalities that have marked the development process in Mexico. Several structural limitations have hampered performance and limited the progress of the health system. Conscious that the lack of financial protection was the major bottleneck, Mexico has embarked on a structural reform to improve health system performance by establishing the System of Social Protection in Health (SSPH), which has introduced new financial rules and incentives. The main innovation of the reform has been the Seguro Popular (Popular Health Insurance), the insurance-based component of the SSPH, aimed at funding health care for all those families, most of them poor, who had been previously excluded from social health insurance. The reform has allowed for a substantial increase in public investment in health while realigning incentives towards better technical and interpersonal quality. This paper describes the main features and initial results of the Mexican reform effort, and derives lessons for other countries considering health-system transformations under similarly challenging circumstances.

    Full Text Available Housing is a fundamental product for every human being irrespective of financial standing. World acclaimed American psychologist, Abraham Maslow ranked shelter as second only to food in his hierarchy of human needs. Despite the importance of housing to the socio-economic development of man and the nation, housing problems have remained endemic throughout the world. In today’s world, some 100 million persons are homeless and more than a billion are inadequately housed. In 2002 housing deficit in Nigeria was put at about 8 million units. Latest statistics indicate that Nigeria requires a whopping 700,000 housing units annually for the next 15 years. The question is why this state of affairs? Why the perennial and unending problems of housing shortages, forced evictions and slum development? The paper examined these issues in Nigeria in order to advance the future prospect of the sector. The paper identified that whilst reforms were been made to all other subsector of the housing industry, land reform necessary to fast track the process was left unattended to by the government. The paper thus advocated for a robust reform of the current land management system in order to impact positively on the housing reform agenda in Nigeria.

  7. Church discipline – semper reformanda in Reformation perspective

    2010-09-01

    Full Text Available Church discipline – is semper reformanda in a time and space warp? Church discipline has become an anachronism in the life of the Christian faith community. In part, this results from a misunderstanding of the fundamental meaning of the term. Its early emphasis was on spiritual nurture, discipling people into the faith and into a relationship with one another and God. By the time of the Reformation, it took on a legalistic and rigid form that militated against its earlier approach. This resulted from a misunderstanding of key reformers from the Reforming tradition such as John Calvin and John Knox, who were concerned to build up individuals within the Christian community to become responsible members of society. In this way, discipline is transformative of individuals and society. The work of discipline was closely related both to pastoral care and Christian education and offered a corrective to Medieval discipline, where the concept of discipline was distorted when the use of punitive discipline as a last resort was elevated to become the norm. This situation was replicated in the post-Reformation period. Consequently, it now needs to be rehabilitated in the form of discipling or mentorship in order to restore its usefulness as an educative tool in the process of the pilgrimage towards the kingdom of God.

  8. Thermoelectric generation coupling methanol steam reforming characteristic in microreactor

    2015-01-01

    Thermoelectric (TE) generator converts heat to electric energy by thermoelectric material. However, heat removal on the cold side of the generator represents a serious challenge. To address this problem and for improved energy conversion, a thermoelectric generation process coupled with methanol steam reforming (SR) for hydrogen production is designed and analyzed in this paper. Experimental study on the cold spot character in a micro-reactor with monolayer catalyst bed is first carried out to understand the endothermic nature of the reforming as the thermoelectric cold side. A novel methanol steam reforming micro-reactor heated by waste heat or methanol catalytic combustion for hydrogen production coupled with a thermoelectric generation module is then simulated. Results show that the cold spot effect exists in the catalyst bed under all conditions, and the associated temperature difference first increases and then decreases with the inlet temperature. In the micro-reactor, the temperature difference between the reforming and heating channel outlets decreases rapidly with an increase in thermoelectric material's conductivity coefficient. However, methanol conversion at the reforming outlet is mainly affected by the reactor inlet temperature; while at the combustion outlet, it is mainly affected by the reactor inlet velocity. Due to the strong endothermic effect of the methanol steam reforming, heat supply of both kinds cannot balance the heat needed at reactor local areas, resulting in the cold spot at the reactor inlet. When the temperature difference between the thermoelectric module's hot and cold sides is 22 K, the generator can achieve an output voltage of 55 mV. The corresponding molar fraction of hydrogen can reach about 62.6%, which corresponds to methanol conversion rate of 72.6%. - Highlights: • Cold spot character of methanol steam reforming was studied through experiment. • Thermoelectric generation Coupling MSR process has been

  9. Improving the Business Trade Licensing Reform Environment

    OpenAIRE

    Gamser, Matthew

    2003-01-01

    This case study of Kenyan business trade licensing shows that red-tape costs can be cut if reform is championed strongly and there is a strong case in terms of costs and benefits. The reform of business registration, trade licensing and other business entry procedures is a cost effective and progressive way to promote indigenous private sector development. But, reform needs more than good cost-benefit analysis and legal drafting; it also requires building constituencies and continuous advocacy.

    2011-01-01

    Although demographic change leaves pay-as-you-go pension systems unsustainable, reforms, such as a higher pension age, are highly unpopular. This contribution looks into the role of intrinsic motivation as a driver for pension reform acceptance. Theoretical reasoning suggests that this driver should be relevant: The choice among different pension reform options (increasing pension age, increasing contributions, cutting pensions) can be analyzed within the framework of an optimal job separatio...

  11. Toward immigration reform.

    Science.gov (United States)

    Franken, Mark

    2005-01-01

    For the most part, immigrants in the United States do not have access to the very safety-net benefits supported by their taxes, nor to essential due-process rights, simply because they are not citizens or legal residents. Contemporary demographics of immigration and post-9/11 security concerns have colored our traditional hospitality as a nation of immigrants and made life more difficult for immigrants. The Catholic Church has a rich history of scriptural and social teaching that addresses the question of immigration. Stories of forced migration in the Pentateuch led to commandments regarding strangers and the responsibility to be welcoming. In the New Testament, we see that the Holy Family themselves were refugees. The Gospel of St. Matthew tells us that we will be judged by the way we respond to migrants and others in need. In Exsul Familia, Pope Pius XII reaffirms the commitment of the church to care for pilgrims, aliens, exiles, and migrants. In Ecclesia in America, Pope John Paul II states that the ultimate solution to illegal immigration is the elimination of global underdevelopment and that, in the meantime, the human rights of all migrants must be respected. In 2003, the bishops of Mexico and the United States jointly issued the pastoral letter Strangers No Longer: Together on the Journey of Hope. In this letter, the bishops say that U.S. immigration policy should protect the human rights and dignity of immigrants and asylum seekers. The bishops also offer a number of proposed public policy responses toward that end. To advance the principles contained in Strangers No Longer, the bishops have decided to mount a national campaign designed to unite and mobilize a growing network of Catholic organizations and individuals, as well as others of good faith. In addition, the campaign will seek to dispel myths and misperceptions about immigrants.

    2011-01-03

    The national health reform agenda appears to have omitted public health. In this article, I outline how public health is different from primary care, and why a holistic approach to reform should include public health. The current reform agenda is very much focused on addressing the problems in acute care and the hospital system, with the focus on primary care being a means to this end. Until the health system is addressed as a whole, with all its essential components integrated and interlinked, truly successful reform of the health system, with genuine long-term vision and sustainability, will not be possible.

    This final report summarizes work accomplished in the Program from January 1, 2001 through December 31, 2004. Most of the key technical objectives for this program were achieved. A breakthrough material system has lead to the development of an OTM (oxygen transport membrane) compact planar reactor design capable of producing either syngas or hydrogen. The planar reactor shows significant advantages in thermal efficiency and a step change reduction in costs compared to either autothermal reforming or steam methane reforming with CO{sub 2} recovery. Syngas derived ultra-clean transportation fuels were tested in the Nuvera fuel cell modular pressurized reactor and in International Truck and Engine single cylinder test engines. The studies compared emission and engine performance of conventional base fuels to various formulations of ultra-clean gasoline or diesel fuels. A proprietary BP oxygenate showed significant advantage in both applications for reducing emissions with minimal impact on performance. In addition, a study to evaluate new fuel formulations for an HCCI engine was completed.

    Full Text Available Since the early 1990s the Australian Commonwealth public sector has undergone significant financialreforms, due primarily to the current federal Liberal government’s drive to improve the financialaccountability of the Commonwealth Government. These reforms include the adoption of accrualaccounting and budgeting and the development and implementation of an outcomes and outputs framework.These reforms culminated in the first full federal budget to be developed on an accrual basis in 1999 – 2000.This paper will examine the implementation of these reforms and the associated processes to determinewhether or not the Commonwealth government is more financially transparent and better able to dischargeits financial accountability. It is argued the complexity of the processes associated with, and the reportingrequirements of these reforms may have actually decreased the level of accountability to the key party towhom accountability is due — the Australian public.

  1. Implementing a Nation-Wide Mental Health Care Reform: An Analysis of Stakeholders' Priorities.

    2016-04-01

    Belgium has recently reformed its mental health care delivery system with the goals to strengthen the community-based supply of care, care integration, and the social rehabilitation of users and to reduce the resort to hospitals. We assessed whether these different reform goals were endorsed by stakeholders. One-hundred and twenty-two stakeholders ranked, online, eighteen goals of the reform according to their priorities. Stakeholders supported the goals of social rehabilitation of users and community care but were reluctant to reduce the resort to hospitals. Stakeholders were averse to changes in treatment processes, particularly in relation to the reduction of the resort to hospitals and mechanisms for more care integration. Goals heterogeneity and discrepancies between stakeholders' perspectives and policy priorities are likely to produce an uneven implementation of the reform process and, hence, reduce its capacity to achieve the social rehabilitation of users.

  2. Thermal and chemical analysis of carbon dioxide reforming of methane using the out-of-pile test facility

    2000-03-01

    In the Japan Atomic Energy Research Institute, a hydrogen production system is being designed to produce hydrogen by means of steam reforming of natural gas (its main composition is methane(CH 4 )) using nuclear heat (10 MW, 1178 K) supplied by the High Temperature Engineering Test Reactor (HTTR). Prior to coupling of the steam reforming system with the HTTR, an out-of-pile demonstration test was planned to confirm safety, controllability and performance of the steam reforming system under simulated operational conditions of the prototype. The out-of-pile test facility simulates key components downstream to an intermediate heat exchanger of the HTTR hydrogen production system on a scale of 1 : 30 and has a hydrogen production capacity of 110 Nm 3 /h using an electric heater as a reactor substitute. The test facility is presently under construction. Reforming of natural gas with carbon dioxide CO 2 (CO 2 reforming) using the out-of-pile test facility is also being considered. In recent years, catalytic reforming of natural gas with CO 2 to synthesis gas (CO and H 2 ) has been proposed as one of the most promising technologies for utilization of those two greenhouse gases. Numerical analysis on heat and mass balance has practical significance in CO 2 reforming when the steam reforming process is adopted in the out-of-pile test. Numerical analysis of CO 2 reforming and reforming of natural gas with CO 2 and steam (CO 2 +H 2 O reforming) have been carried out using the mathematical model. Results such as the methane conversion rate, product gas composition, and the components temperature distribution considering the effects of helium gas temperature, reforming pressure, molar ratio of process gases and so on have been obtained in the numerical analysis. Heat and mass balance of the out-of-pile test facility considering chemical reactions are evaluated well. The methane conversation rates are about 0.36 and 0.35 which correspond to the equilibrium at 1085 and 1100 K for

  3. Dry Reforming of Methane Using a Nickel Membrane Reactor

    Directory of Open Access Journals (Sweden)

    Jonas M. Leimert

    2017-12-01

    Full Text Available Dry reforming is a very interesting process for synthesis gas generation from CH 4 and CO 2 but suffers from low hydrogen yields due to the reverse water–gas shift reaction (WGS. For this reason, membranes are often used for hydrogen separation, which in turn leads to coke formation at the process temperatures suitable for the membranes. To avoid these problems, this work shows the possibility of using nickel self-supported membranes for hydrogen separation at a temperature of 800 ∘ C. The higher temperature effectively suppresses coke formation. The paper features the analysis of the dry reforming reaction in a nickel membrane reactor without additional catalyst. The measurement campaign targeted coke formation and conversion of the methane feedstock. The nickel approximately 50% without hydrogen separation. The hydrogen removal led to an increase in methane conversion to 60–90%.

    Discusses issues faced by LGBT people, such as a lack of equal civil rights and the need for extra legal and financial protection for families because partners cannot be married. The author notes that, in our society, it is no longer acceptable to be racist, but it is still okay to be homophobic. The many campaigns against gay marriage and efforts in the legislature to prevent change toward equal civil rights and protections are prime examples. In our current political climate, two things are very clear: (a) homophobia is freely tolerated and (b) the times are changing as we inch closer to equal rights every day. We are "righting wrongs and reforming rights."

    Mass, heat and momentum transport processes are coupled with catalytic chemical reactions in a methane steam reforming duct. It is often found that endothermic and exothermic reactions in the ducts are strongly integrated by heat transfer from adjacent catalytic combustion ducts. In this paper, a three-dimensional calculation method is developed to simulate and analyze reforming reactions of methane, and the effects on various transport processes in a steam reforming duct. The reformer conditions such as mass balances associated with the reforming reactions and gas permeation to/from the porous catalyst reforming layer are applied in the analysis. The predicted results are presented and discussed for a composite duct consisting of a porous catalyst reaction layer, the fuel gas flow duct and solid layers. Parametric studies are conducted to reveal the importance of reformer designs and operating conditions. The results show that the variables, such as porous layer configuration, temperature and catalyst loading, have significant effects on the transport processes and reformer performance. (author)

    Governments everywhere are implementing reform to improve primary care. However, the existence of a high degree of professional autonomy makes large-scale change difficult to achieve. The purpose of this paper is to elucidate the change dynamics and the involvement of professionals in a primary healthcare reform initiative carried out in the Canadian province of Quebec. An empirical approach was used to investigate change processes from the inception of a public policy to the execution of changes in professional practices. The data were analysed from a multi-level, combined contextualist-processual perspective. Results are based on a longitudinal multiple-case study of five family medicine groups, which was informed by over 100 interviews, questionnaires, and documentary analysis. The results illustrate the multiple processes observed with the introduction of planned large-scale change in primary care services. The analysis of change content revealed that similar post-change states concealed variations between groups in the scale of their respective changes. The analysis also demonstrated more precisely how change evolved through the introduction of "intermediate change" and how cycles of prescribed and emergent mechanisms distinctively drove change process and change content, from the emergence of the public policy to the change in primary care service delivery. This research was conducted among a limited number of early policy adopters. However, given the international interest in turning to the medical profession to improve primary care, the results offer avenues for both policy development and implementation. The findings offer practical insights for those studying and managing large-scale transformations. They provide a better understanding of how deliberate reforms coexist with professional autonomy through an intertwining of change content and processes. This research is one of few studies to examine a primary care reform from emergence to implementation

    2006-12-01

    As an opening of a dialogue on health reforms in Pakistan, the Gateway Paper presents a viewpoint on its proposed directions making a strong case for systems reforms, which need to scope beyond the healthcare system. Positioning the reform process to strengthen Pakistan's health policy cycle, the paper articulates a roadmap for a paradigm shift to achieve health outcomes in Pakistan with major structural reorganization within the health system. The proposed reform points in the four areas namely, reforms within the health sector, overarching measures, reconfiguration of health within an inter-sectoral scope and generating evidence for reforms. Reforms within the health sector focus on developing new models of service delivery and health financing which can enable the state to leverage the private sector outreach to deliver health-related public goods on the one hand and maximize the outreach of the State's health care delivery mechanisms through mainstreaming the role of the private sector on the other, albeit with safeguards. In addition, these call for strengthening the stewardship role to regulate these arrangements. The second area of reform focuses on overarching measures; these include developing frameworks for public-private partnerships which will enable the bringing together of organizations with the mandate to offer public goods and those that could facilitate this goal through the provision of resources, technical expertise or outreach; mainstreaming health into the country's social protection strategy in order to address issues of access and affordability for the poor and introducing civil service and public service reform focused on good governance, accountability, breakdown of institutional corruption which are critical to improving health outcomes. The third area of reform involves broadening health to its inter-sectoral scope, redefinition of objectives and targets within the health sector and garnering support from across the sectors to forester

    Two days of hearings held to consider three bills which would reform nuclear power plant regulation stressed the fact that there has been no resolution of many of the problems identified after the Three Mile Island accident. Principal witnesses were Nunzio Palladino and other members and former members of the Nuclear Regulatory Commission (NRC) and representatives of electric utilities, public utility commissions, citizen groups, and the legal profession. One aspect of current procedures which is not working is meetings held in compliance with sunshine laws. At issue was the process of collegial decision making and whether a structure with a single administrator would better sever the public. NRC commissioners concur that collegial decision making is less efficient, but oppose S. 2291's proposal for an independent Nuclear Safety Board. The tests of S. 1235, S. 2291, and S. 2471 accompany the recorded testimony
