    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

    In this paper a control system for autothermal reforming reactor for diesel fuel is presented. Autothermal reforming reactors and the pertaining purification reactors are used to convert diesel fuel into hydrogen-rich reformate gas, which is then converted into electricity by the fuel cell. The purpose of the presented control system is to control the hydrogen production rate and the temperature of the autothermal reforming reactor. The system is designed in such a way that the two control loops do not interact, which is required for stable operation of the fuel cell. The presented control system is a part of the complete control system of the diesel fuel cell auxiliary power unit (APU).

    Fuel cell systems with integrated autothermal reforming units require active and robust catalysts for H2 production. In pursuit of this, an experimental screening of catalysts utilized in the autothermal reforming of commercial diesel fuels is performed. The catalysts incorporate a monolithic cordierite substrate, an oxide support (γ-Al2O3, La-Al2O3, CeO2, Gd-CeO2, ZrO2, Y-ZrO2) and Rh as the active phase. Experiments are run by widely varying the O2/C and H2O/C molar ratios at different gas hourly space velocities. In most cases, this provokes accelerated catalyst deactivation and permits an informative comparison of the catalysts. Fresh and aged catalysts are characterized by temperature-programmed methods, thermogravimetry and transmission electron microscopy to find correlations with catalytic activity and stability. Using this approach, routes for catalyst deactivation are identified, together with causes of different catalytic activities. Suitable reaction conditions can be derived from our results for the operation of reactors for autothermal reforming at steady-state and under transient reaction conditions, which helps improve the efficiency and the stability of fuel cell systems.

    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.

    This Project Final Report serves to document the project structure and technical results achieved during the 3-year project titled Advanced Autothermal Reformer for US Dept of Energy Office of Industrial Technology. The project was initiated in December 2001 and was completed March 2005. It was a joint effort between Sandia National Laboratories (Livermore, CA), Kellogg Brown & Root LLC (KBR) (Houston, TX) and Süd-Chemie (Louisville, KY). The purpose of the project was to develop an experimental capability that could be used to examine the propensity for soot production in an Autothermal Reformer (ATR) during the production of hydrogen-carbon monoxide synthesis gas intended for Gas-to-Liquids (GTL) applications including ammonia, methanol, and higher hydrocarbons. The project consisted of an initial phase that was focused on developing a laboratory-scale ATR capable of reproducing conditions very similar to a plant scale unit. Due to budget constraints this effort was stopped at the advanced design stages, yielding a careful and detailed design for such a system including ATR vessel design, design of ancillary feed and let down units as well as a PI&D for laboratory installation. The experimental effort was then focused on a series of measurements to evaluate rich, high-pressure burner behavior at pressures as high as 500 psi. The soot formation measurements were based on laser attenuation at a view port downstream of the burner. The results of these experiments and accompanying calculations show that soot formation is primarily dependent on oxidation stoichiometry. However, steam to carbon ratio was found to impact soot production as well as burner stability. The data also showed that raising the operating pressure while holding mass flow rates constant results in considerable soot formation at desirable feed ratios. Elementary reaction modeling designed to illuminate the role of CO2 in the burner feed showed that the conditions in the burner allow for the direct

    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.

    This study focused on measurement of the autothermal reforming of biogas over a Ni based monolithic catalyst.The effects of the steam/CH4 (S/C) ratio,O2/CH4 (O2/C) ratio and temperature were investigated.The CH4 conversions were higher under all examined temperatures than the equilibrium conversion calculated using the blank outlet temperature,because the catalyst layer was heated by the exothermic catalytic partial oxidation reaction.The CH4 conversion increased with increasing O2/C ratio.Moreover,the CH4 conversion was higher than the equilibrium conversion calculated using the blank outlet temperature for O2/C>0.42 and reached about 100% at O2/C=0.55.However,the hydrogen concentration decreased for O2/C>0.45 because hydrogen was combusted to steam in the presence of excess oxygen.On the other hand,the hydrogen and CO2 concentrations increased and the CO concentration decreased with increasing S/C ratio.As a result,it was found that the highest hydrogen concentrations and CH4 conversions were attained at the O2/C ratios of 0.45-0.55 and the S/C ratios of 1.5-2.5.Moreover,the H2/CO ratio could also be controlled in the range from about 2 to 3.5 to give at least 90% CH4 conversion,by regulating the O2/C or S/C ratios.

  10. 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 residence time.

  11. Microchennel development for autothermal reforming of hydrocarbon fuels

    Bae, J.-M.; Ahmed, S.; Kumar, R.; Doss, E.

    Fuel-processing is a bridging technology to assist the commercialization of fuel cell systems in the absence of a hydrogen infrastructure. The Argonne National Laboratory has been developing fuel-processing technologies for fuel cells, and has reported the development of novel catalysts that are active and selective for hydrocarbon-reforming reactions. It has been realized, however, that with pellets or conventional honeycomb catalysts, the reforming process is mass-transport limited. This study addresses the development of catalysts structures with microchannels that are able to reduce the diffusion resistance and, thereby, achieve the same production rate within a smaller reactor bed. The microchannel reforming catalysts are prepared and tested with natural gas and gasoline-type fuels in a microreactor (diameter: 1 cm) at space velocities of up to 250 000 h -1. The catalysts have also been used in engineering-scale reactors (10 kWe; diameter: 7 cm) with similar product qualities. Compared with pellet catalysts, the microchannel catalysts offer a nearly five-fold reduction in catalyst weight and volume.

  13. LABORATORY EQUIPMENT FOR AUTOTHERMAL REFORMING OF ORGANIC MATTER IN SUPERCRITICAL WATER

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available The ability of water to dissolve organic substances is very limited. However, its ability to dissolve them changes if pressure and temperature values reach the so-called critical point (p = 22.06MPa, T = 373.95 °C. Fluid water in this state is called supercritical water (SCW, and values of its physical properties are included among the values of such properties for liquid phase and gaseous phase. Various types of organic matter can be treated in SCW, and it is especially useful for materials that cannot be treated cost-effectively with conventional technologies (incineration, etc.. Suitable input materials are mainly industrial waste or biomass with high water content. Conventional processing of these materials requires energy-intensive drying or densification. Processing the inputs in SCW completely removes these problems, since sufficient water content is a prerequisite for creating a suitable environment for efficient operation of the system. In this paper, glycerol as a by-product of alternative fuel production was chosen for evaluation in the SCW autothermal reforming cycle. The paper analyses the influence of several processing parameters on the operation of model laboratory equipment.

    In this paper, a miniature methanol fuel processor and its controller design is introduced for onboard hydrogen production. The hydrogen is generated via autothermal reforming of methanol. The control scheme consists of a hydrogen flow rate controller and a reforming temperature controller. To deal with uncertain system dynamics and external disturbance, an adaptive sliding mode control algorithm is adopted as the hydrogen flow rate controller for regulating hydrogen flow rate by manipulating methanol flow rate. Additionally, a high-gain observer is implemented to estimate the unmeasurable system state. The stability of closed-loop system is guaranteed by standard Lyapunov analysis. Furthermore, a variable ratio control law is employed as the reforming temperature controller to achieve steady reforming temperature by adjusting the reforming air flow rate. Finally, the effectiveness of the entire system is testified by experimental means.

    Rh doped Ni and Co catalysts, Rh-M/CeO{sub 2}(20 wt %)-Al{sub 2}O{sub 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{sup -1}. The Rh-Ni/CeO{sub 2}(20 wt %)-Al{sub 2}O{sub 3} catalyst (1) exhibited excellent activities, with H{sub 2} and (H{sub 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{sub 2}(20 wt %)-Al{sub 2}O{sub 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.

    This work provides information about the development of an integrated unit for hydrogen production by auto thermal reforming of ethanol with nominal capacity of 1 kg/h H{sub 2} 4.5 (99.995%). The unit is composed by a Fuel Processing Module (FPM), resulting from auto thermal and shift reactor integration, responsible for the thermochemical step, plus an over heater of the liquid input (EtOH and H{sub 2}O), operated recovering thermal energy from PSA blown-down (H{sub 2} Purification Module - MPH2), besides other thermal equipment which completes the integration. Using a computational routine for scaling the process and preliminary performance analysis, it was possible to optimize operating conditions, essential along unit operations design. Likewise, performance estimation of the integrated unit proceeds, which shows efficiency about 72.5% from FPM. Coupled with the PSA recovery rate, 72.7%, the unit could achieve overall energy performance of 52.7%, or 74.4% working in co-generation of hydrogen and heat. (author)

    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.)

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.

    Dias, Joelmir Augusto Costa; Assaf, José Mansur

    The addition of the noble metals Pt, Pd and Ir to the Ni/γ-Al 2O 3 catalyst used in the autothermal reforming of methane was investigated, with the aim of making the reaction ignite without previous reduction of the catalyst with H 2. In TPR-CH 4, the catalysts promoted with Pt and Ir chloride suffered reduction at temperatures lower than 500 °C, while the unpromoted catalyst and those promoted by addition of PdCl 2 did not suffer reduction. Pd promoted the reduction only when added as the nitrate. The catalytic tests of intermittent start-up, alternating with air flow, showed results consistent with those from the TPR-CH 4. Pt- and Ir-promoted catalysts were active in all the start-ups, producing a great quantity of hydrogen, while the sample promoted via paladium chloride did not produce hydrogen in significant quantity, converting methane only to CO 2 and water. The samples promoted via palladium nitrate were very active in autothermal reforming without previous reduction, producing a great quantity of hydrogen.

    Hoang, D. L.; Chan, S. H.; Ding, O. L.

    Experimental and modelling studies have been conducted on catalytic autothermal reforming (ATR) of methane for hydrogen production over a sulfide nickel catalyst on a gamma alumina support. The experiments are performed with different feedstock under thermally neutral conditions. The results show that the performance of the reformer is dependent on the molar air-to-fuel ratio (A/F), the molar water-to-fuel ratio (W/F) and the flowrate of the feedstock mixture. The optimum conditions for high methane conversion and high hydrogen yield are A/F = 3-3.5, W/F = 2-2.5 and a fuel flowrate below 120-250 l h -1. Under these conditions, a methane conversion of 95-99% and a hydrogen yield of 39-41% on a dry basis can be achieved and 1 mole of methane can produce 1.8 moles of hydrogen at an equilibrium reactor temperature of not exceeding 850 °C. A two-dimensional reactor model is developed to simulate the conversion behaviour of the reactor for further study of the reforming process. The model includes all aspects of the major chemical kinetics and the heat and mass transfer phenomena in the reactor. The predicted results are successfully validated with experimental data.

    2016-03-01

    In this paper, we investigated the DME ATR reaction with different types of precious metal (Pt, Rh, Ru)-supported CGO catalysts. We also evaluated the reaction characteristics of DME ATR reaction by modifying certain reforming conditions, including the temperature, the amount of air and water, and the flow rate. The Ru-added CGO catalyst showed the best performance in DME ATR. The operating condition that produced the greatest effect on conversion efficiency was temperature; however the amounts of steam and air were also important with regard to conversion efficiency and the reaction heat. In case higher GHSV conditions the methane yields are increased. To maximize conversion efficiency with thermal neutral operating conditions, we suggest an SCR of 1.5, OCR of 0.45, over temperature of 700 °C, and a GHSV of less than 20,000/h. Under harsh conditions, such as low temperature and high GHSV, the methane yield increases. Therefore, the high temperature DME ATR reaction seems to consist of two main steps: the DME decomposition to methane and the methane autothermal reforming reaction.

    Hydrogen was produced over noble metal (Ir, Ru, Rh, Pd) catalysts supported on various oxides, including γ-Al2O3, CeO2, ZrO2 and La2O3, via the autothermai reforming reaction of ethanol (ATRE) and oxidative reforming reaction of ethanol (OSRE). The conversion of ethanol and selectivites for hydrogen and byproducts such as methane, ethylene and acetaldehyde were studied. It was found that lanthana alone possessed considerable activity for the ATRE reaction, which could be used as a functional support for ATRE catalysts. It was demonstrated that Ir/La2O3 prevented the formation of methane, and Rh/La2O3 encumbered the production of ethylene and acetaldehyde. ATRE reaction was carried out over La2O3-supported catalysts (Ir/La2O3) with good stability on stream, high conversion, and excellent hydrogen selectivity approaching thermodynamic limit under autothermal condition. Typically, 3.4 H2 molecules can be extracted from a pair of ethanol and water molecules over Ir(5wt%)/La2O3. The results presented in this paper indicate that Ir/La2O3 can be used as a promising catalyst for hydrogen production via ATRE reaction from renewable ethanol.

    Solid oxide fuel cell systems used in the aerospace or commercial aviation environment require a compact, light-weight and highly durable catalytic fuel processor. The fuel processing method considered here is an autothermal reforming (ATR) step. The ATR converts Jet-A fuel by a reaction with steam and air forming hydrogen (H2) and carbon monoxide (CO) to be used for production of electrical power in the fuel cell. This paper addresses the first phase of an experimental catalyst screening study, looking at the relative effectiveness of several monolith catalyst types when operating with untreated Jet-A fuel. Six monolith catalyst materials were selected for preliminary evaluation and experimental bench-scale screening in a small 0.05 kWe micro-reactor test apparatus. These tests were conducted to assess relative catalyst performance under atmospheric pressure ATR conditions and processing Jet-A fuel at a steam-to-carbon ratio of 3.5, a value higher than anticipated to be run in an optimized system. The average reformer efficiencies for the six catalysts tested ranged from 75 to 83 percent at a constant gas-hourly space velocity of 12,000 hr 1. The corresponding hydrocarbon conversion efficiency varied from 86 to 95 percent during experiments run at reaction temperatures between 750 to 830 C. Based on the results of the short-duration 100 hr tests reported herein, two of the highest performing catalysts were selected for further evaluation in a follow-on 1000 hr life durability study in Phase II.

    Highly dispersed Ni catalysts on spherical SiO2 were prepared by simple impregnation of Ni(acac)2, [Ni-(NH3)6-n(H2O)n]2+, [Ni(en)3]2+ and [Ni(EDTA)]2-. Pulse adsorption of H2 and TEM analysis results confirmed that Ni was dispersed very well on the surface of SiO2 even after calcination (4 h) and reduction (1 h) at high temperature of 800 ℃. These highly dispersed and uniquely sized Ni crystallites were more stable and more reactive for both autothermal reforming and partial oxidation of methane in fluidized reactor.

    Autothermal reforming (ATR) of n-hexadecane was carried out on zirconia-supported mono- and bimetallic noble metal (Rh, Pt) catalysts at 600, 700, and 800 C. After ATR, the reactivity of coke deposits (2.8-9.9 wt%) on the catalysts was investigated by temperature-programmed oxidation (TPO). Analysis of the results obtained from ATR and TPO experiments at various temperatures and on the different catalysts gave information on the reaction conditions where the detrimental coke can be minimized and allows estimating the nature of carbon deposits. H{sub 2} production increased with temperature on the tested Rh-containing catalysts and the ZrO{sub 2} support, but decreased as a function of temperature on the Pt catalyst. The formation of coke was least at 800 C, evidently due to the intensifying reaction of carbon and steam with increasing temperature, as well as to the better activity of the catalysts. The amount of coke formed was highest at 700 C. Comparison of the TPO profiles obtained for the monometallic Rh and Pt catalysts with the bimetallic RhPt revealed differences in the nature of carbon deposits on their surface. At 600 C, the coke formed on the monometallic Rh and Pt catalysts was located mostly on the support, whereas on the bimetallic RhPt catalyst the formation of this type of coke was suppressed. The bimetallic RhPt catalyst also exhibited better tolerance toward coking at 700 C. Therefore, although the selectivity toward hydrogen was not related to the amount of coke formed, the deactivation patterns differed on the mono- and bimetallic catalysts. (author)

    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.

    This paper discusses the reforming of liquid hydrocarbons to produce hydrogen for fuel cell applications, focusing on gasoline and diesel due to their high hydrogen density and well-established infrastructures. Gasoline and diesel are composed of numerous hydrocarbon species including paraffins, olefins, cycloparaffins, and aromatics. We have investigated the reforming characteristics of several representative liquid hydrocarbons. In the case of paraffin reforming, H 2 yield and reforming efficiency were close to thermodynamic equilibrium status (TES), although heavier hydrocarbons required slightly higher temperatures than lighter hydrocarbons. However, the conversion efficiency was much lower for aromatics than paraffins with similar carbon number. We have also investigated the reforming performance of simulated commercial diesel and gasoline using simple synthetic diesel and gasoline compositions. Reforming performances of our formulations were in good agreement with those of commercial fuels. In addition, the reforming of gas to liquid (GTL) resulted in high H 2 yield and reforming efficiency showing promise for possible fuel cell applications.

    Full Text Available Bio-oil can be obtained via fast pyrolysis of biomass, and typically contains acetic acid (~30 mass %. The acetic acid has often been tested as a model compound for hydrogen production via reforming bio-oil, in which catalysts are a key factor for stable hydrogen production. However, deactivation of catalysts by coking and oxidation hinders the application of the reforming process. Dolomite-derived Ni-based catalysts with Fe additive, MgNi0.2Ca0.8−xFexO2±δ (x = 0–0.8, were successfully synthesized by the hydrothermal synthesis method, and then tested in auto-thermal reforming (ATR of acetic acid (AC. The MgNi0.2Ca0.5Fe0.3O2±δ catalyst performed a stable reactivity in ATR: the conversion of AC reached 100%, and the H2 yield remained stable around 2.6 mol-H2/mol-AC. The catalysts were characterized by X-ray diffraction (XRD, N2 physisorption, X-ray photoelectron spectra (XPS, H2-temperature-programmed reduction (TPR, inductively coupled plasma- atomic emission spectroscopy (ICP-AES and Thermogravimetry (TG; the results show that a periclase-like solid solution of Mg(Ni,FeO and lime were formed via the precursors of dolomite and hydrotalcite, and then transformed into Fe-rich Ni-Fe alloy with basic support of MgO-CaO after reduction. The stable Ni0 spices with basic support can explain the stability and resistance to coking during ATR of AC.

    The transition metals (Cu, Co, and Fe) were applied to modify Ni/Ce0.2Zr0.1Al0.7Oδ catalyst.The effects of transition metals on the catalytic properties of Ni/Ce0.2Zr0.1Al0.7Oδ autothermal reforming of methane were investigated. The Ni-supported catalysts were characterized by XRD, TPR and XPS.Tests in autothermal reforming of methane to hydrogen showed that the addition of transition metals (Cu and Co) significantly increased the activity of catalyst under the conditions of lower reaction temperature,and Ni/Cu0.05Ce0.2Zr0.1Al0.65Oδ was found to have the highest conversion of CH4 among all catalysts in the operation temperatures ranging from 923 K to 1023 K. TPR, XRD and XPS measurements indicated that the cubic phases of CexZr1-xO2 solid solution were formed in the preparation process of catalysts.Strong interaction was found to exist between NiO and CexZr1-xO2 solid solution. The addition of Cu improved the dispersion of NiO, inhibited the formation of NiAl2O4, and thus significantly promoted the activity of the catalyst Ni/Cu0.05Ce0.2Zr0.1Al0.65Oδ.

    We propose a new class of autothermal CO2 -capture process that relies on the integration of chemical looping combustion (CLC) into calcium looping (CaL). In the new process, the heat released during the oxidation of a reduced metallic oxide is utilized to drive the endothermic calcination of CaCO3 (the regeneration step in CaL). Such a process is potentially very attractive (both economically and technically) as it can be applied to a variety of oxygen carriers and CaO is not in direct contact with coal (and the impurities associated with it) in the calciner (regeneration step). To demonstrate the practical feasibility of the process, we developed a low-cost, steel-slag-based, Fe-functionalized CO2 sorbent. Using this material, we confirm experimentally the feasibility to heat-integrate CaCO3 calcination with a Fe(II)/Fe(III) redox cycle (with regards to the heat of reaction and kinetics). The autothermal calcination of CaCO3 could be achieved for a material that contained a Ca/Fe ratio of 5:4. The uniform distribution of Ca and Fe in a solid matrix provides excellent heat transfer characteristics. The cyclic CO2 uptake and redox stability of the material is good, but there is room for further improvement.

    Autothermal reforming (ATR) is one of the leading methods for hydrogen production from hydrocarbons. Liquefied petroleum gas, with propane as the main component, is a promising fuel for on-board hydrogen producing systems in fuel cell vehicles and for domestic fuel cell power generation devices. In this article, propane ATR process is studied and operation conditions are optimized with PRO/Ⅱ ~ from SIMSCI for proton exchange membrane fuel cell application. In the ATR system including water gas shift and preferential oxidation, heat in the hot streams and cold streams is controlled to be in balance. Different operation conditions are studied and drawn in contour plots. The region for ATR reforming with the highest efficiency can thus be identified. One operation point was chosen with the following process parameters: feed temperature for the ATR reactor is 425℃, steam to carbon ratio S/C is 2.08, air stoichiometry is 0.256. Thermal efficiency for the integrated system is calculated to be as high as 84.0 % with 38.27 % H2 and 3.2μl·L-1 CO in the product gas.

Experimentally, CuO/ZnO and alumina support with ZrO₂ sol washcoat catalyst (catalyst slurries) nanoparticles is the catalytically active component of the microreactor. Catalyst slurries have been dried at 298 K for 5 h and then calcined at 623 K for 2 h to increase the surface area and specific pore structures of the washcoat catalyst. The surface area of BET N₂ adsorption isotherms for the as-synthesized catalyst and catalyst/ZrO₂ sol washcoat samples are 62 and 108 ± 2 m²g⁻¹, respectively. The intensities of Cu content from XRD and XPS data indicate that Al₂O₃ with Cu species to form CuAl₂O₄. The EXAFS data reveals that the Cu species in washcoat samples have Cu-O bonding with a bond distance of 1.88 ± 0.02 Å and the coordination number is 3.46 ± 0.05, respectively. Moreover, a hydrogen production rate of 2.16 L h⁻¹ is obtained and the corresponding methanol conversion is 98% at 543 K using the CuO/ZnO with ZrO₂ sol washcoat catalyst.

    Moreno, Angela M.; Wilhite, Benjamin A.

    In this paper, the authors present the first demonstration of a new class of integrated ceramic microchannel reactors for all-in-one reforming of hydrocarbon fuels. The reactor concept employs precision-machined metal distributors capable of realizing complex flow distribution patterns with extruded ceramic microchannel networks for cost-effective thermal integration of multiple chemical processes. The presently reported reactor is comprised of five methanol steam reforming channels packed with CuO/γ-Al 2O 3, interspersed with four methanol combustion channels washcoated with Pt/γ-Al 2O 3, for autothermal hydrogen production (i.e., without external heating). Results demonstrate the capability of this new device for integrating combustion and steam reforming of methanol for autothermal production of hydrogen, owing to the axially self-insulating nature of distributor-packaged ceramic microchannels. In the absence of any external insulation, stable reforming of methanol to hydrogen at conversions >90% and hydrogen yields >70% was achieved at a maximum reactor temperature of 400 °C, while simultaneously maintaining a packaging temperature <50 °C.

    The degradation of sludge solids in an insulated reactor during Autothermal Thermophilic Aerobic Digestion (ATAD) processing results in auto-heating, thermal treatment and total solids reduction, however, the ability to eliminate pathogenic organisms has not been analysed under large scale process conditions. We evaluated the ATAD process over a period of one year in a two stage, full scale Irish ATAD plant established in Killarney and treating mixed primary and secondary sludge, by examining the sludge microbiologically at various stages during and following ATAD processing to determine its ability to eliminate indicator organisms. Salmonella spp. (pathogen) and fecal-coliform (indicator) densities were well below the limits used to validate class A biosolids in the final product. Enteric pathogens present at inlet were deactivated during the ATAD process and were not detected in the final product using both traditional microbial culture and molecular phylogenetic techniques. A high DNase activity was detected in the bulk sludge during the thermophilic digestion stage which may be responsible for the rapid turn over of DNA from lysed cells and the removal of mobile DNA. These results offer assurance for the safe use of ATAD sludge as a soil supplement following processing.

    Ni catalysts supported on Al2O3, ZrO2-Al2O3, CeO2-Al2O3 and ZrO2-CeO2-Al2O3 were prepared by co-precipitation method, and their catalytic performances for autothermal reforming of methane to hydrogen were investigated.The Ni-supported catalysts were characterized by XRD, TPR and XPS. The relationship between the structures and catalytic activities of the catalysts was discussed. The results showed that the catalytic activity and stability of the Ni/ZrO2-CeO2-Al2O3 catalyst was better than those of other catalysts with the highest CH4 conversion, H2/CO and H2/COx ratio at 750 ℃. The cat-alyst showed a little deactivation along the reaction time during its 72 h on stream with the mean deactivation rate of 0.08%/h. The catalytic performance of the Ni/ZrO2-CeO2-Al2O3 catalyst was also affected by reaction temperature, nO2: nCH4 molar ratio and nH2O : nCH4 molar ratio. TPR, XRD and XPS measurements indicated that the formation of ZrO2-CeO2 solid solu-tion could improve the dispersion of NiO, and inhibit the formation of NiAl2O4, and thus significantly promoted the catalytic activity of the Ni/ZrO2-CeO2-Al2O3 catalyst.

    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.

    Catalytic combustion of hydrocarbon fuels has been considered as an effective method in power MEMS. However, the ca talyst deactivation, mainly caused by carbon deposition, is occurred ubiquity in the catalytic reforming progress. In this paper, the effects of humidity ratio on the CH4/wet air auto-thermal reforming reaction with Ni catalyst on the micro-chamber's surface were simulated. The results show that increasing the humidity ratio will promote the methane reforming reaction. The heat dissipating capacity of auto-thermal reforming and the density of carbon deposition reduce with increasing the humidity ratio. The CH4 conversion rate, density of carbon deposition and mass fraction of H2 were changed very little, they reach 53.1%, 3.07% and 2.40x10-6 kmol/m2respectively while the humidity ratio exceeds 1.20 kg/kg and mixture flow rate is 36 g/h.%微动力装置中碳氢燃料催化燃烧被认为是有效的方法,但燃烧室内燃料催化重整普遍存在由积碳导致的催化剂失活等问题.本文采用数值方法研究了微细腔中甲烷湿空气在镍基催化剂上的自热重整反应,重点分析含湿量对甲烷自热重整反应及积碳特性的影响.结果表明:含湿量将增强甲烷重整反应;自热反应散热量和表面积碳浓度均随含湿量增加而降低.混合物质量流量为36 g/h时,当含湿量d>1.20 kg/kg后,甲烷转化率、氢气质量分数和积碳浓度变化幅度很小,分别接近 53.1%、3.07%和2.40x10-6 kmol/m2.

    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.

    Singularity theory is combined with asymptotic analysis to determine the exact uniqueness-multiplicity boundary and ignition and extinction locus for the non-adiabatic, autothermal tubular reactor model. It is found that the steady-state behavior of the nonadiabatic reactor is described by the two limiting cases of adiabatic and strongly cooled models. The adiabatic case has been examined in a previous study. In this paper, the authors develop limiting models to describe the strongly cooled asymptotes. The authors also classify the different types of bifurcation diagrams of conversion vs. residence time using the results of singularity theory with a distinguished parameter. Analytical criteria are developed for predicting the conditions under which autothermal operation is feasible when heat losses are significant.

    In this paper singularity theory, large activation energy asymptotic, and numerical methods are used to present a comprehensive study of the steady-state multiplicity features of three classical adiabatic autothermal reactor models: tubular reactor with internal heat exchange, tubular reactor with external heat exchange, and the CSTR with external heat exchange. Specifically, the authors derive the exact uniqueness-multiplicity boundary, determine typical cross-sections of the bifurcation set, and classify the different types of bifurcation diagrams of conversion vs. residence time. Asymptotic (limiting) models are used to determine analytical expressions for the uniqueness boundary and the ignition and extinction points. The analytical results are used to present simple, explicit and accurate expressions defining the boundary of the region of autothermal operation in the physical parameter space.

    1980-02-01

    The current efforts to develop distillate oil-steam reforming processes are reviewed, and the applicability of these processes for integration with the fuel cell are discussed. The development efforts can be grouped into the following processing approaches: high-temperature steam reforming (HTSR); autothermal reforming (ATR); autothermal gasification (AG); and ultra desulfurization followed by steam reforming. Sulfur in the feed is a key problem in the process development. A majority of the developers consider sulfur as an unavoidable contaminant of distillate fuel and are aiming to cope with it by making the process sulfur-tolerant. In the HTSR development, the calcium aluminate catalyst developed by Toyo Engineering represents the state of the art. United Technology (UTC), Engelhard, and Jet Propulsion Laboratory (JPL) are also involved in the HTSR research. The ATR of distillate fuel is investigated by UTC and JPL. The autothermal gasification (AG) of distillate fuel is being investigated by Engelhard and Siemens AG. As in the ATR, the fuel is catalytically gasified utilizing the heat generated by in situ partial combustion of feed, however, the goal of the AG is to accomplish the initial breakdown of the feed into light gases and not to achieve complete conversion to CO and H/sub 2/. For the fuel-cell integration, a secondary reforming of the light gases from the AG step is required. Engelhard is currently testing a system in which the effluent from the AG section enters the steam-reforming section, all housed in a single vessel. (WHK)

    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{sub 4}-CO{sub 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{sub 4}-CO{sub 2} feedstock, and (4) fabricate and test a bench-scale hydrogen production unit. Experimental data obtained from catalytic reformation of the CH{sub 4}-CO{sub 2} and CH{sub 4}-CO{sub 2}-O{sub 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)

    This work makes an exergetic analysis in the production of hydrogen by Autothermal Reforming of Methane, ATR. ATR is combination between Steam Methane Reforming, SMR, and partial reforming. In the ATR, the reforming reaction can be endothermic, exothermic or neutral depending on the relation CH{sub 4}-H{sub 2}O-O{sub 2}. The first step of ATR is the reforming where synthesis gas, containing H{sub 2}, H{sub 2}O, CO{sub 2}, CO and residual CH{sub 4} is formed. Thermodynamic chemical equilibrium is assumed in all reactions of process. After reforming, Shift reactions produce more H{sub 2} reacting CO and H{sub 2}O. After Shift Reactions the synthesis gas is purified by absorption and adsorption. The absorption is made in Diethanolamine, DEA, and produce CO{sub 2} as by product. The adsorption is made in fixed beds of molecular sieves. This procedure can produce H{sub 2} highly pure (99,999 %, wt) proper to fuel cells. The exergetic analysis identifies the sources of irreversibility of the process. It was employed the Fuel-Product concept where the Control Volumes, CV, may present as product the total, physical or chemical exergies. The desegregation of the exergy into physical and chemical is essential to evaluate the perform of CV's. The results show that the main source of irreversibility is the Reformer. (author)

  5. The Amsterdam Process: A Structurationist Perspective on EU Treaty Reform

    Directory of Open Access Journals (Sweden)

    Thomas Christiansen

    1999-01-01

    Full Text Available Intergovernmental Conferences are generally seen as key events in the design of the European Union. This paper challenges this traditional view. Arguing that treaty reform should be regarded as a continuous process rather than a series of events, the paper develops a procedural understanding of constitutional change based on structuration theory. In such a perspective, analytical attention is re-directed from the political limelight of largely ceremonial events to the more obscure 'valleys' the periods between the IGC summits in which the more momentous developments of European integration occur. The study of past instances of constitutional change as well as an analysis of the IGC leading to the Amsterdam Treaty demonstrate the significance of a wider set of actors and of the structural environment: the trajectory of past decisions, the multilateral generation of reform agendas, the institutionalised patterns of negotiation and decision-making and the constitutionalisation of the EU order. This severely limits the ability of national governments to negotiate on the basis of 'national interests' and thus dissolves one of the cornerstones of intergovernmentalism the over-arching significance of IGCs.

    2004-01-01

    NASA Glenn Research Center is interested in developing Solid Oxide Fuel Cell for use in aerospace applications. Solid oxide fuel cell requires hydrogen rich feed stream by converting commercial aviation jet fuel in a fuel processing process. The grantee's primary research activities center on designing and constructing a test facility for evaluating injector concepts to provide optimum feeds to fuel processor; collecting and analyzing literature information on fuel processing and desulfurization technologies; establishing industry and academic contacts in related areas; providing technical support to in-house SOFC-based system studies. Fuel processing is a chemical reaction process that requires efficient delivery of reactants to reactor beds for optimum performance, i.e., high conversion efficiency and maximum hydrogen production, and reliable continuous operation. Feed delivery and vaporization quality can be improved by applying NASA's expertise in combustor injector design. A 10 KWe injector rig has been designed, procured, and constructed to provide a tool to employ laser diagnostic capability to evaluate various injector concepts for fuel processing reactor feed delivery application. This injector rig facility is now undergoing mechanical and system check-out with an anticipated actual operation in July 2004. Multiple injector concepts including impinging jet, venturi mixing, discrete jet, will be tested and evaluated with actual fuel mixture compatible with reforming catalyst requirement. Research activities from September 2002 to the closing of this collaborative agreement have been in the following areas: compiling literature information on jet fuel reforming; conducting autothermal reforming catalyst screening; establishing contacts with other government agencies for collaborative research in jet fuel reforming and desulfurization; providing process design basis for the build-up of injector rig facility and individual injector design.

    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.)

  8. An Analysis of Biogas Reforming Process on Ni/YSZ and Ni/SDC Catalysts

    Full Text Available The conversion of biogas to electricity presents an attractive niche application for fuel cells. Thus attempts have been made to use biogas as a fuel for high temperature fuel cell systems such as SOFC. Biogas can be converted to hydrogen-rich fuel in a reforming process. For hydrocarbon-based fuel, three types of fuel conversion can be considered in reforming reactions: an external reforming system, an indirect internal reforming system and a direct internal reforming system. High-temperature SOFC eliminates the need for an expensive external reforming system. The possibility of using internal reforming is one of the characteristics of high temperature fuel cells like SOFC. However, for high-temperature operation, thermal management of the SOFC system becomes an important issue. To properly carry out thermal management, both detailed modeling and numerical analyses of the phenomena occurring inside the SOFC system is required. In the present work, the process of reforming biogas on a Ni/YSZ and a Ni/SDC catalyst has been numerically and experimentally investigated. Measurements including different thermal boundary conditions, steam-to-carbon ratios and several different fuel compositions were taken. A numerical model containing methane/steam reforming reaction, dry reforming reaction and shift reaction has been proposed to predict the gas mixture composition at the outlet of the reformer. The results of the numerical computation were compared with experimental data and good agreement has been found. The results indicate the importance of combined, numerical and experimental studies in the design of SOFC reformers. The combined approach used leads to the successful prediction of the outlet gas composition for different modelling conditions.

    2009-01-01

    The health sector in the Punjab (Pakistan) faces many problems, and, the government introduced reforms during 1993-2000. This paper explores the policy process for the reforms. A case study method was used and, to assist this, a conceptual framework was developed. Analysis of four initiatives indicated that there were deviations from the government guidelines and that the policy processes used were weak. The progress of different reforms was affected by a variety of factors: the immaturity of the political process and civil society, which together with innate conservatism and resistance to change on the part of the bureaucracy resulted in weak strategic sectoral leadership and a lack of clear purpose underpinning the reforms. It also resulted in weaknesses in preparation of the detail of reforms leading to poor implementation. The study suggests a need for broadening the stakeholders' base, building the capacity of policy-makers in policy analysis and strengthening the institutional basis of policymaking bodies.

    Ethanol steam reforming has been studied in a fluidized bed (in order to ensure bed isothermicity) on commercial catalysts for methane reforming. The results allow analyzing the effect of temperature (in 300-700◦C range), and both metal and support nature on the reaction indices (ethanol conversion, yields and selectivities to H2 and byproducts (CO2, CO, CH4 and C2H4O)). Special attention has been paid to catalysts’ stability by comparing the evolution of the reaction indices with time on stream at 500◦C (minimum CO formation) and 700◦C (minimum deactivation by coke deposition). Although they provide a slightly lower H2 yield, the results evidence a good behaviour of Ni based catalysts, indicating that they are an interesting alternative of more expensive Rh based ones.

    Full Text Available The structural reform becomes the most visible initiative of the Bologna process. However, today the reform serves as an umbrella for comprehensive reform processes in national systems of higher education. In Central and Eastern European countries the Bologna process is not only strongly connected to the overall political transformation, but provides for the higher education policy makers an opportunity for the Europeanization of the sector. The implementation of the three-cycle system (the reform of organizational dimensions creates a demand for other reforms, and under this agenda have been released a numerous fundamental questions and debates on higher education systems. In a narrow concept, the Bologna process at the present implies systemic (e.g. core functions and role of different higher education institutions, the future of university and non-university sector, programmatic (e.g. at different program levels different curricular emphasis, arrangements and functions; vocationalization of the academic curriculum, procedural (e.g. new modes and arrangements of teaching changes, and shift from accent on horizontal to vertical differences (e.g. the set up of stratified and hierarchical national systems based on reputation and prestige, especially in research quality, and from input to output oriented higher education. In a broad sense, and on the basis of national implementation experiences, we can also conceptualize the Bologna process as governance or recently finance reform. As the concepts behind these reform initiatives suggests, the original objectives of the Bologna process is reinterpreted and overwrote, by the Lisbon Strategy and several national higher educational policy objectives.

    From the chemical point of view the reforming process of heavy hydrocarbons such as Associated Petroleum Gas (APG) is very complex. One of the main issue is a set of undesired chemical reactions that causes deposition of solid carbon and consequently block catalytic property of a reactor. The experimental investigation is crucial to design APG reforming reactors. However, the experiment needs to be preceded by careful thermodynamical analysis to design safe operation conditions. In case of small number of reactants and reactions such as in case of steam reforming of pure methane, the problem can be solved by treating each equilibrium reaction constant as an element of the system of non-linear equations. The system of equations can be solved by Newton-Raphson method. However in case of large number of reactants and reaction, such as in case of APG reforming this method is inefficient. A large number of strongly non-linear equations leads often to converge problem. In this paper the authors suggest to use different approach called Parametric Equation Method. In this method a system of non-linear equations is replaced by a set of single non-linear equations solved separately. The methods were used to simulate steam reforming of methane-ethane rich fuel. The results of computations from both methods were juxtaposed and comparative study were conducted. Finally safe operation conditions for steam reforming of methane-ethane fuel were calculated and presented.

    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.

    Full Text Available The reform process of the state and implicitly of the public administration was a priority for the past governments of Romania. During 2004- 2009, within the reform process, the main actors involved in the coordination, implementation and monitoring of reform measures were: the Prime Minister, the Superior Council for Public Administration Reform, Public Policy Coordination and Structural Adjustment, the Ministry of Public Finance, the General Secretariat of Government, Ministry of Administration and Interior (renamed for a short time Ministry of Interior and Administrative Reform, the Central Unit for Public Administration Reform, National Institute of Administration, the National Agency of Civil Servants, and the National Modernizers Network. For evaluation of aspects related to the reform process it was designed a selective research within the members of the National Modernizers Network, for assessing their perception of the public administration reform undertaken by the institutions presented above. Evaluating their opinion can be an important point in the revitalization of the area of the administration reform process. Also, the research conducted aimed at assessing the degree of modernizers’ involvement in activities related to important aspects of the reform process: strategic planning, formulating and evaluating public policies, financial management, human resources management, decentralization, introduction of new information and communication technologies and administrative simplification.

    Full Text Available In this study, genetic algorithm was used to predict the reaction kinetics of Iraqi heavy naphtha catalytic reforming process located in Al-Doura refinery in Baghdad. One-dimensional steady state model was derived to describe commercial catalytic reforming unit consisting of four catalytic reforming reactors in series process. The experimental information (Reformate composition and output temperature for each four reactors collected at different operating conditions was used to predict the parameters of the proposed kinetic model. The kinetic model involving 24 components, 1 to 11 carbon atoms for paraffins and 6 to 11 carbon atom for naphthenes and aromatics with 71 reactions. The pre-exponential Arrhenius constants and activation energies were determined after fine tuning of the model results with experimental data. The input to the optimization is the compositions for 21 components and the temperature for the effluent stream for each one of the four reactors within the reforming process while the output of optimization is 142 predicted kinetic parameters for 71 reactions within reforming process. The differential optimization technique using genetic algorithm to predict the parameters of the kinetic model. To validate the kinetic model, the simulation results of the model based on proposed kinetic model was compared with the experimental results. The comparison between the predicted and commercially results shows a good agreement, while the percentage of absolute error for aromatics compositions are (7.5, 2, 8.3, and 6.1% and the temperature absolute percentage error are (0.49, 0.5, 0.01, and 0.3% for four reactors respectively.

  19. 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

    Biofiltration has become the preferred technology to treat offgases from wastewater treatment facilities because of its low operating cost. However, the underlying principles of biofiltration have only recently begun to be understood. In this study, the dynamic variation in the composition of offgases from a full-scale autothermal thermophilic aerobic digestion (ATAD) was characterized, and the performance of a biofilter treating the offgases was examined. Gas and liquid phase streams in the biofilter were measured to identify the mechanisms responsible for the removal of odorants. ATAD is a sludge process that has been found to emit relatively high quantities of ammonia (NH{sub 3}) and reduced sulfur compounds (RSCs). An existing ATAD and biofilter system at a site in Oregon was used in the study. Gas flows were calculated from air velocities that were measured with a hotwire thermo-anemometer at the biofilter inlet. Sampling was performed on an hourly basis over a 24 hour period. Liquid flows were measured hourly at the biofilter leachate sump inlet. It was observed that the ATAD reactors released NH{sub 3} and RSCs in a cyclic pattern. Gas phase concentrations of NH{sub 3} increased with time and location along the digester sequence. A wet scrubber removed nearly 85 per cent of NH{sub 3} and 60 per cent of H{sub 2}S. The removal efficiencies in the biofilter were more than 99 per cent for hydrogen sulfide and methyl mercaptan, and more than 94 per cent for dimethyl sulfide and dimethyl disulfide. The removal efficiency of each compound demonstrated the effectiveness of the biofilter and wet scrubber combination for the ATAD offgas removal. 24 refs., 5 tabs., 9 figs.

  4. Efficient utilization of greenhouse gas in a gas-to-liquids process combined with carbon dioxide reforming of methane.

    2010-02-15

    A process model for a gas-to-liquids (GTL) process mainly producing Fischer-Tropsch (FT) synthetic oils has been developed to assess the effects of reforming methods, recycle ratio of unreacted syngas mixture on the process efficiency and the greenhouse gas (GHG) emission. The reforming unit of our study is composed of both steam reforming of methane (SRM) and carbon dioxide reforming of methane (CDR) to form syngas, which gives composition flexibility, reduction in GHG emission, and higher cost-competitiveness. With recycling, it is found that zero emission of CO(2) from the process can be realized and the required amount of natural gas (NG) can be significantly reduced. This GTL process model has been built by using Aspen Plus software, and it is mainly composed of a feeding unit, a reforming unit, an FT synthesis unit, several separation units and a recycling unit. The composition flexibility of the syngas mixture due to the two different types of reforming reactions raises an issue that in order to attain the optimized feed composition of FT synthesis the amount of flow rate of each component in the fresh feed mixture should be determined considering the effects of the recycle and its split ratio. In the FT synthesis unit, the 15 representative reactions for the chain growth and water gas shift on the cobalt-based catalyst are considered. After FT synthesis, the unreacted syngas mixture is recycled to the reforming unit or the FT synthesis unit or both to enhance process efficiency. The effect of the split ratio, the recycle flow rate to the FT reactor over the recycle flow rate to the reforming unit, on the efficiency of the process was also investigated. This work shows that greater recycle to the reforming unit is less effective than that to the FT synthesis unit from the standpoint of the net heat efficiency of the process, since the reforming reactions are greatly endothermic and greater recycle to the reformer requires more energy.

    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

    Emergency departments (ED) function to diagnose, stabilize, manage and dispose patients as efficiently as possible. Although problems may be suspected at triage, ED physician input is required at each step of the patient journey through the ED, from diagnosis to disposition. If we want timely diagnosis, appropriate treatment and great outcomes, then ED processes should connect patients and physicians as quickly as possible. This article discusses the key concepts of ED patient flow, value and efficiency. Based on these fundamentals, it describes the significant impact of ED process improvements implemented on measures of ED efficiency at a large community ED in Ontario, Canada.

    Hydrogen production plants are among major sources of CO{sub 2} emissions into the atmosphere. The objective of this paper is to explore new routes to hydrogen production from natural gas (or methane) with drastically reduced CO{sub 2} emissions. One approach analyzed in this paper is based on thermocatalytic decomposition (or pyrolysis) of methane into hydrogen gas and elemental carbon over carbon-based catalysts. Several heat input options to the endothermic process are discussed in the paper. The authors conduct thermodynamic analysis of methane decomposition in the presence of small amounts of oxygen in an autothermal (or thermo-neutral) regime using AspenPlus(TM) chemical process simulator. Methane conversion, products yield, effluent gas composition, process enthalpy flows as a function of temperature, pressure and O{sub 2}/CH{sub 4} ratio has been determined. CO{sub 2} emissions (per m{sup 3} of H{sub 2} produced) from the process could potentially be a factor of 3-5 less than from conventional hydrogen production processes. Oxygen-assisted decomposition of methane over activated carbon (AC) and AC-supported iron catalysts over wide range of temperatures and O{sub 2}/CH{sub 4} ratios was experimentally verified. Problems associated with the catalyst deactivation and the effect of iron doping on the catalyst stability are discussed. (author)

    Full Text Available Problem statement: CO2 reforming is one of the methods to utilize a greenhouse gas to produce syngas, an important feed for methanol and Fischer-Tropsch synthesis. However, CO2 reforming is strong endothermic reaction requiring large amount of supplied energy. Partial oxidation, an exothermic reaction, is combined with CO2 reforming to serve the energy requirement. Thus, the optimum ranges of O2 and CO2 fed to the process corresponding to feedstock are needed to find. Moreover, one of the most important problems found in this process is solid carbon formation. Therefore, the operating range in which the carbon formation can be avoided is also required to study. Approach: In this study CH4 was used as feedstock. The optimum rage of O2 and CO2 fed to the process was found by using thermodynamic equilibrium method based on minimization of Gibbs free energy. The Lagrange multiplier method was conducted to form the equations and they were solved by the Newton-Raphson method. The solid carbon formation zone was also simulated. Results: The simulation showed that higher reaction temperature caused higher CH4 and CO2 conversions. Syngas production increased with increasing temperature. Operating the process with high temperature or high O2/CH4 and CO2/CH4 rations could eliminate solid carbon formation. Increase of O2/CH4 ration higher than 0.1 led decreasing syngas while increase of CO2/CH4 ration caused increasing H2 and CO. However, when CO2/CH4 ration was higher than 0.85, increasing CO2/CH4 ration showed insignificant change of syngas concentration. Conclusion: The combined partial oxidation and CO2 reforming of method should be operated with reaction temperature of 1050 K. The optimum range of CH4:CO2:O2 for this process is 1: 0.85-1.0:0.1-0.2.

    Full Text Available The Romanian health sector went through a process of reform began in 2000 which entered into a final adjustment phase in 2010 when the economic crisis, the health professionals accelerated trend of labour migration, the precarious health of the population brought new challenges to the unsolved existing problems. Nurses are numerically the most important category of health professionals. Since 1994 they experienced a convergent movement of professionalization in the interior of the nurse profession. The aim of the study is to explore the nurses’ perceptions of the impact of the health care system reform on their own profession and on the internal process of professionalization. As a result a quantitative research was conducted on a sample including 411 nurses of different specialties working in Iasi county. The results of the research point out the significant impact of factors related to the reform of the health care system on the quality of the care process, on the nurses’ work conditions and professional satisfaction. The external disruptive factors produce negative effects on nurses’ group cohesion, despite the centripetal efforts of the professional organization and induce a slowdown movement of the nurses professionalization process.

    In the construction of reactors or pressure vessels for oil chemical plants and nuclear power stations, mono block open-die forging rings are often utilized. Generally, a large forged ring is manufactured by means of enlarging forging with reductions of the wall thickness. During the enlarging process the circular ring is often distorted and becomes an ellipse in shape. However the shape control of the ring is a complicated work. This phenomenon makes the matter still worse in forging of larger rings. In order to make precision forging of large rings, we have developed the forging method using a v-shape anvil. The v-shape anvil is geometrically adjusted to fit the distorted ring in the final circle and reform automatically the shape of the ring during enlarging forging. This paper has analyzed the reforming process of distorted ring by computer program based on F.E.M. and examined the effect on the precision of ring forging. (author)

    The present work focuses on the development of efficient desulphurization processes for multi-fuel reformers for hydrogen production. Two processes were studied: liquid hydrocarbon desulphurization and H{sub 2}S removal from reformate gases. For each process, materials with various chemical compositions and microporous structures were synthesized and characterized with respect to their physicochemical properties and desulphurization ability. In the case of liquid phase desulphurization, the adsorption of sulphur compounds contained in diesel fuel under ambient conditions was studied employing as sorbents, zeolite-based materials, i.e. NaY, HY and metal ion-exchanged NaY and HY, as well as a high-surface area activated carbon (AC), for three different diesel fuels with sulphur content varying between 5 and 180 ppmw. Among all sorbents studied, AC showed the best desulphurization performance followed by cerium ion-exchanged HY. The gas phase desulphurization experiments involved the evaluation of zinc-based mixed oxides, synthesized by non-conventional (combustion synthesis) techniques on high steam content reformate gas mixtures.

    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

    Currently, many countries throughout the world are reforming their health services. Even though these reforms differ according to the country's characteristics, they share many policies, one of which is the promotion of social participation in health-related matters. This policy, however, is not new in the field of health service organization. Throughout the last century, individual or collective collaboration between the population and health services has been promoted by several philosophies and concepts with different aims: from the search for collaboration with the general public to broaden public health system coverage to the promotion of the creation of mechanisms that would allow society to exercise control over these services' performance. Nevertheless, for the public to be involved with these services, several factors concerning both the services themselves and the population, need to converge. Although the theoretical frameworks that have encouraged social participation throughout the history of the development of health systems differ considerably, their practical implementation shares many common elements in all periods, from participation as a means of obtaining certain objectives to being an end in itself, as a democratic process. This can also be applied to the current promotion of social participation policies in the context of health care reforms, which are analyzed using Colombia and Brazil as examples.

    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.

    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.

    An attempt has been made to develop a flexible system to produce very pure H{sub 2} with high efficiency from renewable bio-based recourses. First, such model compounds as ethanol, glycerol, sorbitol and glucose, have been tested for H{sub 2} production via sorption enhanced steam reforming (SESR) over Co-Ni/hydrotalcite-like (HTls) derived catalyst and CaO-based CO{sub 2} acceptor. The experimental results show that all of feedstocks, even heavy feedstocks, were able to offer high H{sub 2} purity (97.3approx99.1%) and yield at low steam to carbon (S/C = 1.3approx6) ratio in comparison to the corresponding steam reforming process. In addition, the studied system also presents encouraging potential for improvement of energy efficiency. Chemical looping combustion (CLC) was coupled to the cyclic multi-step SESR process to assist the acceptor regeneration by using multifunctional Pd/Co-Ni/HTls catalyst. With coupling of CLC to SESR, H{sub 2} concentration in the gas effluent of the SESR reactions was still higher than 95 mol% on a dry basis. The assembled CLC-SESR process has inherent high efficiency in H{sub 2} production. (Author)

    Governments around the world are struggling to address persistent disparities in health care access. However, this priority competes with many others for support in moving onto and up the political agenda. In this paper, a novel method of agenda-setting analysis is developed by merging and modifying the Hall and Kingdon models. As a case study, this method is used to explore how health financing reform reached the policy agenda in South Africa between the years 2000 and 2010. Certain factors are identified that could have determined the agenda-setting process: a change in government, increase in the cost of private medical schemes, and increase in support for reform from various stakeholders. Further analysis, using a conceptual framework of interacting trends and shocks, identifies the growing middle class, the private sector, and workers unions as powerful actors and outlines further factors that may have contributed to the process: a broad political shift in the second half of the decade and the changing prioritisation of HIV/AIDS. Study findings have relevance to academics and policy makers in South Africa and beyond.

    In this paper, fuel-processing technologies are developed for application in residential power generation (RPG) in solid oxide fuel cells (SOFCs). Kerosene is selected as the fuel because of its high hydrogen density and because of the established infrastructure that already exists in South Korea. A kerosene fuel processor with two different reaction stages, autothermal reforming (ATR) and adsorptive desulfurization reactions, is developed for SOFC operations. ATR is suited to the reforming of liquid hydrocarbon fuels because oxygen-aided reactions can break the aromatics in the fuel and steam can suppress carbon deposition during the reforming reaction. ATR can also be implemented as a self-sustaining reactor due to the exothermicity of the reaction. The kW e self-sustained kerosene fuel processor, including the desulfurizer, operates for about 250 h in this study. This fuel processor does not require a heat exchanger between the ATR reactor and the desulfurizer or electric equipment for heat supply and fuel or water vaporization because a suitable temperature of the ATR reformate is reached for H 2S adsorption on the ZnO catalyst beds in desulfurizer. Although the CH 4 concentration in the reformate gas of the fuel processor is higher due to the lower temperature of ATR tail gas, SOFCs can directly use CH 4 as a fuel with the addition of sufficient steam feeds (H 2O/CH 4 ≥ 1.5), in contrast to low-temperature fuel cells. The reforming efficiency of the fuel processor is about 60%, and the desulfurizer removed H 2S to a sufficient level to allow for the operation of SOFCs.

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

    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.

    Full Text Available To survive in the current shipbuilding industry, it is of vital importance for shipyards to have the ship components’ accuracy evaluated efficiently during most of the manufacturing steps. Evaluating components’ accuracy by comparing each component’s point cloud data scanned by laser scanners and the ship’s design data formatted in CAD cannot be processed efficiently when (1 extract components from point cloud data include irregular obstacles endogenously, or when (2 registration of the two data sets have no clear direction setting. This paper presents reformative point cloud data processing methods to solve these problems. K-d tree construction of the point cloud data fastens a neighbor searching of each point. Region growing method performed on the neighbor points of the seed point extracts the continuous part of the component, while curved surface fitting and B-spline curved line fitting at the edge of the continuous part recognize the neighbor domains of the same component divided by obstacles’ shadows. The ICP (Iterative Closest Point algorithm conducts a registration of the two sets of data after the proper registration’s direction is decided by principal component analysis. By experiments conducted at the shipyard, 200 curved shell plates are extracted from the scanned point cloud data, and registrations are conducted between them and the designed CAD data using the proposed methods for an accuracy evaluation. Results show that the methods proposed in this paper support the accuracy evaluation targeted point cloud data processing efficiently in practice.

    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).

    Zhang, Chundong; Jun, Ki-Won; Ha, Kyoung-Su; Lee, Yun-Jo; Kang, Seok Chang

    2014-07-15

    Two process models for carbon dioxide utilized gas-to-liquids (GTL) process (CUGP) mainly producing light olefins and Fischer-Tropsch (F-T) synthetic oils were developed by Aspen Plus software. Both models are mainly composed of a reforming unit, an F-T synthesis unit and a recycle unit, while the main difference is the feeding point of fresh CO2. In the reforming unit, CO2 reforming and steam reforming of methane are combined together to produce syngas in flexible composition. Meanwhile, CO2 hydrogenation is conducted via reverse water gas shift on the Fe-based catalysts in the F-T synthesis unit to produce hydrocarbons. After F-T synthesis, the unreacted syngas is recycled to F-T synthesis and reforming units to enhance process efficiency. From the simulation results, it was found that the carbon efficiencies of both CUGP options were successfully improved, and total CO2 emissions were significantly reduced, compared with the conventional GTL processes. The process efficiency was sensitive to recycle ratio and more recycle seemed to be beneficial for improving process efficiency and reducing CO2 emission. However, the process efficiency was rather insensitive to split ratio (recycle to reforming unit/total recycle), and the optimum split ratio was determined to be zero.

    The aim of this study was to investigate biohydrogen production from biofuel-reforming processes using new multi-component bulk-type cobalt-based catalysts. The addition of different components to improve the catalytic performance was studied. Monometallic cobalt catalyst and catalysts containing Ru (ca. 1%) and/or Na (ca. 0.5%) were characterized and tested in the 623-673 K temperature range in ethanol steam reforming (ESR) with a steam/carbon ratio (S/C) of 3. The catalysts showed a high performance for hydrogen production and, except for H(2) and CO(2), only small amounts of by-products were obtained, depending on the temperature and the catalyst used. The catalyst containing both Ru and Na (Co-Ru(Na)) showed the best catalytic behavior in ESR. It operated stably for at least 12 days under cycles of oxidative steam reforming of glycerol/ethanol mixtures (S/C=2) and activation under O(2).

    @@ Automotive exhaust is currently one of the major pollution sources. As a pollution-free and energy-saving power supply for electric vehicles, the fuel cell is the best candidate because of its high energy conversion efficiency (50%~70%) and zero or nearly zero emission. Hydrogen is the fuel for the proton exchange membrane fuel cell (PEMFC). The on-board generation of hydrogen using liquid alcohols and hydrocarbons is the most practical way for PEMFC vehicles. Nowadays, PEMFC technology has been well developed, and is gradually in the stage of commercial application, while the hydrogen-generating technology has become the bottle-neck for the practical utilization of fuel cells. The miniaturization of the hydrogen source is prerequisite for its practical application.[1,2].

    New energy sources are needed if energy supply and demand are to remain in balance. At the same time, the level of emissions needs to be reduced to minimise their contribution to the greenhouse effect. Renewable energy sources, and hydrogen (H2), have been attracting much attention, and more efficient technologies for energy recovery have been developed. Among these are fuel cells. H2 is not a source of energy but an energy carrier, which needs to be produced from a primary fuel (hydroca...

    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.

    Biomass-derived methane-rich gases such as landfill gas (LFG), biogas and digester gas are promising renewable resources for near-future production of hydrogen. The technical and economical feasibility of hydrogen production via catalytic reforming of LFG and other methane-rich gases is evaluated in this paper. The thermodynamic equilibrium calculations and experimental measurements of reformation of methane-rich CH{sub 4}-CO{sub 2} mixtures over Ni-based catalyst were conducted. The problems associated with the catalyst deactivation due to carbon lay down and effects of steam and oxygen on the process sustainability were explored. Two technological approaches distinguished by the mode of heat input to the endothermic process (i.e., external vs autothermal) were modeled using AspenPlus trademark chemical process simulator and validated experimentally. A 5 kW{sub th} pilot unit for hydrogen production from LFG-mimicking CH{sub 4}-CO{sub 2} mixture was fabricated and operated. A preliminary techno-economic assessment indicates that the liquid hydrogen production costs are in the range of 3.00-7.00 per kilogram depending upon the plant capacity, the process heat input option and whether or not carbon sequestration is included in the process.

  1. The Transference of Gender-based Norms in the Law Reform Process: A Reflection on my Work in Thailand

    2013-04-01

    Full Text Available In 2008, I spent a year as a Rule of Law specialist in Thailand with the International Rescue Committee (IRC, as part of a fellowship program for human rights lawyers. I was assigned the task of facilitating the development of a comprehensive legal code for the refugee camps along the border between Thailand and /Burma. As part of my work, I also sought to increase gender-based protection under the law through the incorporation of Thai and international human rights norms. This paper is a reflection on the processes that occurred during my time at IRC. The reform project approached the transference of contentious international norms for protection of women and girls in two ways: a through the inclusive design of the law reform process and b the establishment of a prohibition on rules that clearly violated international or national law. By forming a representative drafting committee and placing an emphasis on community consultation as a precursor to code finalisation, refugee perspectives, particularly female perspectives, were given scope to inform interpretations of national and international legal standards. By requiring international and national legal compliance and placing an emphasis on explanation and clarification of international and national standards in discussions, the project supported downward transference of international norms to a specific community context. We hoped that, as a product of these two normative flows, the resulting legal code would be a sustainable mechanism for gender-based protection and redress in cases of sexual and gender-based violence. During negotiations, it became evident that the inclusive design of the law reform process had a more positive impact on the success of norms transference than the actual substance of the norm. The norms that were most readily accepted were those introduced by law reform committee members themselves. Local norm translators played a pivotal role in the norms diffusion process

  2. Performance and economic assessments of a solid oxide fuel cell system with a two-step ethanol-steam-reforming process using CaO sorbent

    The hydrogen production process is known to be important to a fuel cell system. In this study, a carbon-free hydrogen production process is proposed by using a two-step ethanol-steam-reforming procedure, which consists of ethanol dehydrogenation and steam reforming, as a fuel processor in the solid oxide fuel cell (SOFC) system. An addition of CaO in the reformer for CO2 capture is also considered to enhance the hydrogen production. The performance of the SOFC system is analyzed under thermally self-sufficient conditions in terms of the technical and economic aspects. The simulation results show that the two-step reforming process can be run in the operating window without carbon formation. The addition of CaO in the steam reformer, which runs at a steam-to-ethanol ratio of 5, temperature of 900 K and atmospheric pressure, minimizes the presence of CO2; 93% CO2 is removed from the steam-reforming environment. This factor causes an increase in the SOFC power density of 6.62%. Although the economic analysis shows that the proposed fuel processor provides a higher capital cost, it offers a reducing active area of the SOFC stack and the most favorable process economics in term of net cost saving.

    The n-heptane reforming and the cyclopentane hydrogenolysis reactions over noble metal monometallic catalysts (0.3% Pt), bimetallic catalysts (0.3% Pt, x% Re, x=0.1, 0.3, 0.9 and 2.0, sulfided) and trimetallic catalysts (0.3% Pt, 0.3% Re, y% Sn, y=0.1, 0.3, 0.6 and 0.9, unsulfided) were studied. The metal function was supported over a chlorided {gamma}-alumina that provided the acid function. The reforming of n-heptane was performed at 450{sup o}C, molar ratio H{sub 2}/n-C{sub 7}=4 and WHSV=7.3 while the hydrogenolysis of cyclopentane was performed at 350{sup o}C, H{sub 2}/CP=20 and WHSV=2.4. The sulfided 0.3Pt-0.3Re catalyst (with 0.06% S) was found to be the best performing bimetallic one. It had a great stability, typical of this kind of catalysts, and also produced a reformate with a high iso-heptanes/toluene ratio. This is advantageous for fulfilling the current environmental regulations that limit the amount of aromatic hydrocarbons in reformulated gasolines. The best trimetallic catalyst was 0.3Pt-0.3Re-0.6Sn which had a similar activity and selectivity as sulfided 0.3Pt-0.3Re, though it displayed a higher stability and a lower hydrogenolysis activity, without the need of presulfidation. Tin affected the metal and acid functions of the catalyst simultaneously and inhibited them to such different degrees that a very convenient metal/acid activity ratio was obtained, resulting in an improvement of the activity, selectivity and stability of the catalysts. It can be concluded that it is possible to prepare trimetallic naphtha reforming catalysts of the Pt-Re-Sn kind with a better performance than conventional sulfided Pt-Re catalysts and with the additional advantage that they do not need complicated sulfiding pretreatments. This simplifies the commercial operation of the reformer unit and enables the application of this catalyst to continuously operated processes.

    Pigram, John J.

    1993-04-01

    In the past decade far-reaching reforms have taken place in the Australian water industry. Extensive restructuring of water administration has been accompanied by increased evidence of willingness by public agencies to consider alternative institutional arrangements to the traditional regulatory approach to water allocation and use. In irrigated agriculture, a market-based system linked to enforceable property rights to water is seen as preferable to rule-based management of water resources. However, significant social and economic considerations and political realities constrain the unfettered operation of water markets. The challenge facing the irrigation industry in Australia is to put in place institutional arrangements which reflect the most appropriate mix of incentive-based and regulatory mechanisms for water management.

    Steam-reforming is an effective approach for upgrading methane and hydrocarbon of coke-oven gas into CO and H2, but the kinetic behavior needs more study. We investigated the conversion of methane in coke-oven gas by steam reforming process in an electric tubular flow at 14 kPa with temperature varying from 500℃ to 950℃, and developed a kenetic model for , ignoring the effects of adsorption and diffusion. The optimal dynamic conditions for methane conversion 14 kPa are as follows: the ratio of the amount of water to the amount of methane is from 1.1 to 1.3; the reaction temperature is from 1 223 K to 1 273 K. The methane conversion rate is larger than 95% when the ratio of the amount of water to the amount of methane is 1.2 at a temperature above 1 223 K with the residence time up to 0.75 s.

In this project, active, stable, and selective catalysts were developed for the reaction systems of interest and their production 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 for hydrogen separation from reactive mixtures. These membranes were successfully scaled up to TRL4 and used in various lab-scale reactors for water gas shift (WGS, using both packed bed and fluidized bed reactors, and Fischer-Tropsch (FTS using packed bed reactors and in prototype reactors for WGS and FTS. Mixed ionic-electronic conducting membranes in capillary form were also developed for high temperature oxygen separation from air. These membranes can be used for both Autothermal Reforming (ATR and Oxidative Coupling of Methane (OCM reaction systems to increase the efficiency and the yield of the processes. The production of these membranes was scaled up to TRL3–4. The project also developed adequate sealing techniques to be able to integrate the different membranes in lab-scale and prototype reactors.

    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

    A first principles-based dynamic model for a continuous catalyst regeneration (CCR) platforming process, the UOP commercial naphtha catalytic reforming process, is developed in this paper. The lumping details of the naphtha feed and reaction scheme of the reaction model are given. The process model is composed of the reforming reaction model with catalyst deactivation, the furnace model and the separator model, which is capable of capturing the major dynamics that occurs in this process system. Dynamic simulations are performed based on Gear numerical algorithm and method of lines (MOL), a numerical technique dealing with partial differential equations (PDEs). The results of simulation are also presented. Dynamic responses caused by disturbances in the process system can be correctly predicted through simulations.

  12. Thermodynamic equilibrium calculations of hydrogen production from the combined processes of dimethyl ether steam reforming and partial oxidation

    Science.gov (United States)

    Semelsberger, Troy A.; Borup, Rodney L.

    Thermodynamic analyses of producing a hydrogen-rich fuel-cell feed from the combined processes of dimethyl ether (DME) partial oxidation and steam reforming were investigated as a function of oxygen-to-carbon ratio (0.00-2.80), steam-to-carbon ratio (0.00-4.00), temperature (100 °C-600 °C), pressure (1-5 atm) and product species. Thermodynamically, dimethyl ether processed with air and steam generates hydrogen-rich fuel-cell feeds; however, the hydrogen concentration is less than that for pure DME steam reforming. Results of the thermodynamic processing of dimethyl ether indicate the complete conversion of dimethyl ether to hydrogen, carbon monoxide and carbon dioxide for temperatures greater than 200 °C, oxygen-to-carbon ratios greater than 0.00 and steam-to-carbon ratios greater than 1.25 at atmospheric pressure (P = 1 atm). Increasing the operating pressure has negligible effects on the hydrogen content. Thermodynamically, dimethyl ether can produce concentrations of hydrogen and carbon monoxide of 52% and 2.2%, respectively, at a temperature of 300 °C, and oxygen-to-carbon ratio of 0.40, a pressure of 1 atm and a steam-to-carbon ratio of 1.50. The order of thermodynamically stable products (excluding H 2, CO, CO 2, DME, NH 3 and H 2O) in decreasing mole fraction is methane, ethane, isopropyl alcohol, acetone, n-propanol, ethylene, ethanol and methyl-ethyl ether; trace amounts of formaldehyde, formic acid and methanol are observed. Ammonia and hydrogen cyanide are also thermodynamically favored products. Ammonia is favored at low temperatures in the range of oxygen-to-carbon ratios of 0.40-2.50 regardless of the steam-to-carbon ratio employed. The maximum ammonia content (i.e., 40%) occurs at an oxygen-to-carbon ratio of 0.40, a steam-to-carbon ratio of 1.00 and a temperature of 100 °C. Hydrogen cyanide is favored at high temperatures and low oxygen-to-carbon ratios with a maximum of 3.18% occurring at an oxygen-to-carbon ratio of 0.40 and a steam

  15. Reformer Fuel Injector

    2004-01-01

    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

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

    2016-03-01

    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.

    Morrison argued that demography, economy, and technology drive the evolution of industries from a formative first-generation state ("First Curve") to a radically different way of doing things ("Second Curve") that is marked by new skills, strategies, and partners. The current health-reform movement in the United States reflects these three key evolutionary trends: surging medical needs of an aging population, dramatic expansion of Medicare spending, and care delivery systems optimized through powerful information technology. Successful transition from a formative first-generation state (First Curve) to a radically different way of doing things (Second Curve) will require new skills, strategies, and partners. In a new world that is value-driven, community-centric (versus hospital-centric), and prevention-focused, orthopaedic surgeons and health-care administrators must form new alliances to reduce the cost of care and improve durable outcomes for musculoskeletal problems. The greatest barrier to success in the Second Curve stems not from lack of empirical support for integrated models of care, but rather from resistance by those who would execute them. Porter's five forces of competitive strategy and the behavioral analysis of change provide insights into the predictable forms of resistance that undermine clinical and economic success in the new environment of care. This paper analyzes the components that will differentiate orthopaedic care provision for the Second Curve. It also provides recommendations for future-focused orthopaedic surgery and health-care administrative leaders to consider as they design newly adaptive, mutually reinforcing, and economically viable musculoskeletal care processes that drive the level of orthopaedic care that our nation deserves-at a cost that it can afford.

    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.

    Full Text Available A Cr- or Ag-doped TiO2 film was prepared by sol-gel and dip-coating process and used as the photocatalyst for CO2 reforming under the visible light. The ratio of amount of Cr or Ag added to amount of Ti in TiO2 sol solution (R varied from 0 to 100 wt% or 0 to 50 wt%, respectively. The total layer number of Cr- or Ag-doped TiO2 film (N coated was changed. The CO2 reforming performance with the Cr- or Ag-doped TiO2 film was tested under a Xe lamp with or without ultraviolet (UV light. As a result, when N equals to 1, the concentration of CO which was a product from CO2 reforming was maximized in Cr doping case for R = 70 wt% and in Ag doping case for R = 1 wt%, respectively. The best result of concentration of CO = 8306 ppmV, concentration of CH4 = 1367 ppmV, concentration of C2H6 = 1712 ppmV is obtained when top=7 with Cr doping in this study.

  4. Life cycle inventory analysis of hydrogen production by the steam-reforming process: comparison between vegetable oils and fossil fuels as feedstock

    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)

  5. Chile's health sector reform: lessons from four reform periods.

    de la Jara, J J; Bossert, T

    1995-01-01

    This paper applies an interdisciplinary approach to analyze the process of health reform in four significant periods in Chilean history: (1) the consolidation of state responsibility for public health in the 1920s, (2) the creation of the state-run National Health Service in the 1950s, (3) the decentralization of primary care and privatization of health insurance in the 1980s, and (4) the strengthening of the mixed public-private market in the 1990s. Building on the authors' separate disciplines, the paper examines the epidemiological, political and economic contexts of these reforms to test simple hypotheses about how these factors shape reform adoption and implementation. The analysis underlines: (1) the importance of epidemiological data as an impetus to public policy; (2) the inhibiting role of economic recession in adoption and implementation of reforms: and (3) the importance of the congruence of reforms with underlying political ideology in civil society. The paper also tests several hypotheses about the reform processes themselves, exploring the role of antecedents, interest groups, and consensus-building in the policy process. It found that incremental processes building on antecedent trends characterize most reform efforts. However, interest group politics and consensus building were found to be complex processes that are not easily captured by the simple hypotheses that were tested. The interdisciplinary approach is found to be a promising form of analysis and suggests further theoretical and empirical issues to be explored.

    Thermodynamic analysis was applied to study combined partial oxidation and carbon dioxide reforming of methane in view of carbon for-mation.The equilibrium calculations employing the Gibbs energy minimization were performed upon wide ranges of pressure (1-25 atm),temperature (600-1300 K),carbon dioxide to methane ratio (0-2) and oxygen to methane ratio (0-1).The thermodynamic results were compared with the results obtained over a Ru supported catalyst.The results revealed that by increasing the reaction pressure methane conversion decreased.Also it was found that the atmospheric pressure is the preferable pressure for both dry reforming and partial oxidation of methane and increasing the temperature caused increases in both activity of carbon and conversion of methane.The results clearly showed that the addition of O2 to the feed mixture could lead to a reduction of carbon deposition.

    Full Text Available When the crackle sounds started to be heard after the middle of the 17th century, that this wasn’t a temporary sound was understood. In order to understood the reason of these illnesses, old laws and sources were being examined and these were being told to the sultans and statesmen who could take the State to a traditional structure. The Ottoman State fell in luxury and dissipation in the pursuit of a tulip in the 18th century. In this peace term, the Ottomans knew Europeans very closely. The Ottoman State’s widening policy gave shape to its State structure and inner order. The Ottoman administrators sent ambassadors to Vienna and Paris after the Treaty of Passarowitz and wanted them to inform themselves not only about politics and diplomacy but also about social and cultural events and interesting things. Europe, which was examined by Ottoman Statesmen with a new eye, was living “Enlightenment Age”. It was understood that in reform studies made in the 18th century the Ottoman remained behind Europe. The effect of the West is clearly seen in these innovation studies. The effect of the West is clearly seen in these innovation studies. Although reforms studies were tried to be made in every area in this term, especially military area reforms were given importance. The Ottoman State stopped its widening policy across Europe and shaped its inner order and State structure.

    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.

    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.

    Full Text Available 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.

    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

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.

  1. Reformation process of the neuronal template for nestmate-recognition cues in the carpenter ant Camponotus floridanus.

    Ants use cuticular hydrocarbons (CHC-profiles) as multicomponent recognition cues to identify colony members (nestmates). Recognition cues (label) are thought to be perceived during ant-ant encounters and compared to a neuronal template that represents the colony label. Over time, the CHC-profile may change, and the template is adjusted accordingly. A phenotype mismatch between label and template, as happens with CHC-profiles of foreign workers (non-nestmates), frequently leads to aggressive behavior. We investigated the template reformation in workers of the carpenter ant Camponotus floridanus by masking their antennae with postpharyngeal gland (PPG) extracts from nestmates or non-nestmates. The behavioral response of manipulated workers encountering unmanipulated workers was measured independently after 2 and after 15 h. After 2 h of incubation, workers treated with either of the two PPG-extracts showed low aggression towards nestmates and high aggression towards non-nestmates. In contrast, after 15 h of incubation, workers treated with non-nestmate PPG-extract showed low aggression towards both nestmates and non-nestmates. The slow (>2 h) adjustment of the template indicates a reformation localized in the central nervous system rather than in chemosensory neurons. In addition, our data show that template adjustment to a new CHC-profile does not impair the assessment of the old CHC-profile as nestmate label.

    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.

    A new 18-lump kinetic model for naphtha catalytic reforming reactions is discussed. By developing this model as a user module, a whole industrial continuous catalytic reforming process is simulated on Aspen plus plat form. The technique utilizes the strong databases, complete sets of modules, and flexible simulation tools of the Aspen plus system and retains the characteristics of the proposed kinetic model. The calculated results are in fair agreement with the actual operating data. Based on the model of the whole reforming process, the process is optimized and the optimization results are tested in the actual industrial unit for about two months. The test shows that the process profit increases about 1000yuan·h-1 averagely, which is close to the calculated result.

    In this article, a multiobjective optimization strategy for an industrial naphtha continuous catalytic reforming process that aims to obtain aromatic products is proposed. The process model is based on a 20-lumped kinetics reaction network and has been proved to be quite effective in terms of industrial application. The primary objectives include maximization of.yield of the aromatics and minimization of the yield of heavy aromatics. Four reactor inlet temperatures, reaction pressure, and hydrogen-to-oil molar ratio are selected as the decision variables. A genetic algorithm,which is proposed by the authors and named as the neighborhood and archived genetic algorithm (NAGA), is applied to solve this mulfiobjective optimization problem. The relations between each decision variable and the two objectives are also proposed and used for choosing a suitable solution from the obtained Pareto set.

    The gradual deepening of reform, the rapid economic growth and the spread of corruption co-exist in China during the 30 years since the implementation of the reform and opening-up policy. Academic circles at home and abroad have devel-oped various theories to explain the historical phenomenon.“Double paradox”is a typical one among them. As is shown in the historical process of reform in the new period, reforms is a process to break the inherent interest structure, and the difficulty of reform lies in the areas where corruption is most likely to occur. To fight against corruption, we must correctly handle the rela-tionship among reform, development and anti-corruption, which can guarantee the stability of reform and development. Mean-while, reform is a fundamental path for the prevention of corruption. The construction of anti-corruption and the comprehensive deepening of reform should be given synchronized consideration, deployment and implementation so as to safeguard the smooth promotion of reform. What’s more, we should be guided by important issues, unceasingly improve our ability to construct an-ti-corruption, strengthen the top-level design and overall scheme, and connect anti-corruption prevention with polices and reg-ulations of reform. Last, we should promote reform on the basis of the rule of law, prevent the possible conflicts of interest from changing into real corruptive behaviors and strengthen the supervision of reform. In this way, we can ensure the improvement and achievement of our reform.%改革开放30多年来,中国出现改革逐步深化、经济快速增长与腐败现象蔓延并存的历史现象。国内外学术界对这种改革、发展与腐败互动关系的现象存在多种理论解释,其中比较有代表性就是“双重悖论”。新时期的改革历史进程表明,改革是打破固有利益格局的过程,改革的重难点领域往往是腐败现象易发高发的区域。反腐廉政建设必须正确处

  9. The Finish Municipal Reform

    Full Text Available The article aims at evaluating the municipal amalgamation process as a way of reforming local government, by two criteria – efficiency in service provision and level of democracy. Those issues are applied onto a Finnish case study, as amalgamation is more common in Northern Europe. The author gives a review of amalgamation studies in the world and of the extensive evaluation reports of amalgamation reform in Finland. The paper examines amalgamation policy from two perspectives – from the instrumental or goal-oriented view and from the process aspect. The findings on the relatively high number of instances of amalgamation in Finland are the following: the main process-driving factors were political parties that mostly supported the reform and the underlying urge to construct larger entities which made municipalities take part in the process. The level of efficiency in the New, amalgamated municipalities is not necessarily higher, as efficient service provision can be found both in small and large municipalities. Efficiency is more determined by the dynamics of a municipal economy while the size of a municipality alone does not make a difference. As amalgamations change the nature of local political life they affect democracy both positively and negatively.

  18. High-Temperature Desulfurization of Heavy Fuel-Derived Reformate Gas Streams for SOFC Applications

    Flytzani-Stephanopoulos, Maria; Surgenor, Angela D.

    2007-01-01

    Desulfurization of the hot reformate gas produced by catalytic partial oxidation or autothermal reforming of heavy fuels, such as JP-8 and jet fuels, is required prior to using the gas in a solid oxide fuel cell (SOFC). Development of suitable sorbent materials involves the identification of sorbents with favorable sulfidation equilibria, good kinetics, and high structural stability and regenerability at the SOFC operating temperatures (650 to 800 C). Over the last two decades, a major barrier to the development of regenerable desulfurization sorbents has been the gradual loss of sorbent performance in cyclic sulfidation and regeneration at such high temperatures. Mixed oxide compositions based on ceria were examined in this work as regenerable sorbents in simulated reformate gas mixtures and temperatures greater than 650 C. Regeneration was carried out with dilute oxygen streams. We have shown that under oxidative regeneration conditions, high regeneration space velocities (greater than 80,000 h(sup -1)) can be used to suppress sulfate formation and shorten the total time required for sorbent regeneration. A major finding of this work is that the surface of ceria and lanthanan sorbents can be sulfided and regenerated completely, independent of the underlying bulk sorbent. This is due to reversible adsorption of H2S on the surface of these sorbents even at temperatures as high as 800 C. La-rich cerium oxide formulations are excellent for application to regenerative H2S removal from reformate gas streams at 650 to 800 C. These results create new opportunities for compact sorber/regenerator reactor designs to meet the requirements of solid oxide fuel cell systems at any scale.

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.

  3. Ecological tax reform

    1996-12-31

    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.

The economy of GTL plants depends very much on the natural gas price and there is a strong incentive to reduce the investment cost and in addition there is a need to improve energy efficiency and carbon efficiency. A model is constructed based on the available information in open literature. This model is used to simulate the GTL process with UNISIM DESIGN process simulator. In the FT reactor with cobalt based catalyst, Co2 is inert and will accumulate in the system. Five placements of Co2 removal unit in the GTL process are evaluated from an economical point of view. For each alternative, the process is optimized with respect to steam to carbon ratio, purge ratio of light ends, amount of tail gas recycled to syngas and FT units, reactor volume, and Co2 recovery. The results show that carbon and energy efficiencies and the annual net cash flow of the process with or without Co2 removal unit are not significantly different and there is not much to gain by removing Co2 from the process. It is optimal to recycle about 97 % of the light ends to the process (mainly to the FT unit) to obtain higher conversion of CO and H2 in the reactor. Different syngas configurations in a gas-to-liquid (GTL) plant are studied including auto-thermal reformer (ATR), combined reformer, and series arrangement of Gas Heated Reformer (GHR) and ATR. The Fischer-Tropsch (FT) reactor is based on cobalt catalyst and the degrees of freedom are; steam to carbon ratio, purge ratio of light ends, amount of tail gas recycled to synthesis gas (syngas) and Fischer-Tropsch (FT) synthesis units, and reactor volume. The production rate of liquid hydrocarbons is maximized for each syngas configuration. Installing a steam

    Since the 1980's psychiatric care in Spain changed considerably (Reforma psiquiátrica española). In the course of this reform, many positive results were achieved. An extensive community network of mental health centres was build up which resulted in the majority of psychiatric patients being integrated in the Spanish general health care system and making a better organized mental health care structure possible. New legislation also improved the care and civil rights of patients. An analysis of the experiences of the Spanish psychiatric reform shows that the tendency to retain the old mental hospitals, alongside the other institutions still exists. The process of deinstitutionalization and the original aims of the psychiatric reform cannot only be satisfied by the closure of large psychiatric hospitals as during the reform new aspects and problems as well the great complexity of the task have become apparent. This article together with the details of the Spanish sources gives the German public a good overview of the developments in Spanish psychiatry.

    The catalytic reforming of naphtha is one of the major refinery processes, designed to increase the octane number of naphtha or to produce aromatics. The naphtha used as catalytic reformer feedstock usually contains a mixture of paraffins, naphthenes, and aromatics in the carbon number range C{sub 6} to C{sub 10}. The detailed chemical composition of the feed is necessary to predict the aromatics and hydrogen production as well as the operation severity. The analysis of feed naphtha is usually reported in terms of its ASTM distillation curve and API or specific gravity. Since reforming reactions are described in terms of lumped chemical species (paraffins, naphthenes and aromatics), a feed characterisation technique should be useful in order to predict reforming operating conditions and detect feed quality changes. Unfortunately online analyzer applications as cromatography or recently introduced naphtha NMR [1] are scarce in most of refineries. This work proposes an algorithmic characterisation method focusing on its main steps description. The method could help on the subjects previously described, finally a calculation example is shown.

  13. Kristeva's Reformation

    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 conversion of the C3 organics propane, propene, isopropanol and acetone in auto-thermal and endothermic steam reforming conditions has been investigated over a Pd-Cu/Al{sub 2}O{sub 3} catalyst in a flow reactor. Although several reactions may occur at lower temperatures (like dehydrogenation, oxidative dehydrogenation, dehydration and combustion), steam reforming of 2-propanol, acetone and propane only start above 850K and with incomplete selectivity. Cracking and methanation lower the selectivity to CO{sub x} and hydrogen. The C-C bond breaking step is considered to be rate determining. The presence of an oxygenated functional group is consequently not useful to lower reaction temperature, although the use of the alcohol and the ketone may be interesting because of the renewable nature of these reactants. Steam reforming of propene starts at significantly lower temperature (600-700K) and is by far the most selective to CO{sub x} and hydrogen over our catalyst. (author)

    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)

  20. 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.

    Thermal plasma technology can be efficiently used in the production of hydrogen and hydrogen-rich gases from methane and a variety of fuels. This paper describes progress in plasma reforming experiments and calculations of high temperature conversion of methane using heterogeneous processes. The thermal plasma is a highly energetic state of matter that is characterized by extremely high temperatures (several thousand degrees Celsius) and high degree of dissociation and substantial degree of ionization. The high temperatures accelerate the reactions involved in the reforming process. Hydrogen-rich gas (50% H{sub 2}, 17% CO and 33% N{sub 2}, for partial oxidation/water shifting) can be efficiently made in compact plasma reformers. Experiments have been carried out in a small device (2--3 kW) and without the use of efficient heat regeneration. For partial oxidation/water shifting, it was determined that the specific energy consumption in the plasma reforming processes is 16 MJ/kg H{sub 2} with high conversion efficiencies. Larger plasmatrons, better reactor thermal insulation, efficient heat regeneration and improved plasma catalysis could also play a major role in specific energy consumption reduction and increasing the methane conversion. A system has been demonstrated for hydrogen production with low CO content ({approximately} 1.5%) with power densities of {approximately} 30 kW (H{sub 2} HHV)/liter of reactor, or {approximately} 10 m{sup 3}/hr H{sub 2} per liter of reactor. Power density should further increase with increased power and improved design.

    @@ On July 21, 2005, the People's Bank of China announced a new reform plan, according to which, RMB would no longer be pegged to the U.S. dollar but would reform the exchange rate regime by moving into a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. ① The reform is an important step in the process of China's reform and opening-up. Hence it has special significance for economic development of China. However,what merits attention is that the present international monetary regime is unstable, financial system is very fragile and big powers have shown an unwillingness to take financial cooperation.② This has posed great challenges to the process of RMB exchange rate reform. Now I would like to examine the possible risks of the reform and then try to make some suggestions through making some analysis of the status quo of international monetary and financial system.

    CeO2-promoted Ni/Al2O3-ZrO2 (Ni/Al2O3-ZrO2-CeO2) catalysts were prepared by a direct sol-gel process with citric acid as gelling agent.The catalysts used for the methane reforming with CO2 was studied by infrared spectroscopy (IR), thermal gravimetric analysis (TGA), microscopic analysis, X-ray diffraction (XRD) and temperature-programmed reduction (TPR).The catalytic performance for CO2 reforming of methane to synthesis gas was investigated in a continuous-flow micro-reactor under atmospheric pressure.TGA, IR, XRD and microscopic analysis show that the catalysts prepared by the direct sol-gel process consist of Ni particles with a nanostructure of around 5 nm and an amorphous-phase composite oxide support.There exists a chemical interaction between metallic Ni particles and supports, which makes metallic Ni well dispersed, highly active and stable.The addition of CeO2 effectively improves the dispersion and the stability of Ni particles of the prepared catalysts, and enhances the adsorption of CO2 on the surface of catalysts.The catalytic tests for methane reforming with CO2 to synthesis gas show that the Ni/Al2O3-ZrO2-CeO2 catalysts show excellent activity and stability compared with the Ni/Al2O3 catalyst.The excellent catalytic activity and stability of the Ni/Al2O3-ZrO2-CeO2 are attributed to the highly, uniformly and stably dispersed small metallic Ni particles, the high reducibility of the Ni oxides and the interaction between metallic Ni particles and the composite oxide supports.

    A process of pressurized gasification and power generation in a hybrid system of Solid Oxide Fuel Cell (SOFC) and gas turbine enables an efficient use of biomass. This process requires tar reforming in order to protect the SOFC from plugging. Tars must be converted at 5 bar absolute pressure (bara) while avoiding secondary steam reforming of methane in order to reduce the required heat input for the tar reformer. This can be realized at low reforming temperatures (

    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.

    Steam reforming (SR) of oxygenated species like bio-oil or ethanol can be used to produce hydrogen or synthesis gas from renewable resources. However, deactivation due to carbon deposition is a major challenge for these processes. In this study, different strategies to minimize carbon deposition...... on Ni-based catalysts during SR of ethanol were investigated in a flow reactor. Four different supports for Ni were tested and Ce0.6Zr0.4O2 showed the highest activity, but also suffered from severe carbon deposition at 600 °C or below. Operation at 600 °C or above were needed for full conversion...... 400 ppm of the carbon in the feed at approx. 600 °C. The different promoters did not influence the product distribution to any significant extent. Selective poisoning with small amounts of K2SO4 on Ni–CeO2/MgAl2O4 at 600 °C decreased carbon deposition from 900 to 200 ppm of the carbon in the feed...

    The dissertation presents the fundamentals of hydrogen gas processing and CO gas purification methods and, on this basis, develops a method for energetic modularisation of the gas treatment process. All process stages are modelled and analyzed on the basis of mass and energy balances. The theoretical discussion of solution methods for the balance equations of the various process stages is limited to the steam reforming and CO gas purification system. Parameters are defined for energetic assessment of the process variants. The method leads to the identification of energetically optimized process variants. Its main goal is the optimum utilisation of process-internal energy and mass flows. The graphic pinch method is a key component of the method presented; it is adapted to the exemplary process. [German] In der Dissertation wird, ausgehend von der Darstellung der Grundlagen der Wasserstoffgasaufbereitungs- und CO-Gasreinigungsverfahren, eine Methodik zur energetischen Modularisierung des Gasaufbereitungsprozesses entwickelt. Die Modellierung und Analyse der einzelnen Prozessstufen erfolgt auf der Basis von Masse- und Energiebilanzen. Die theoretische Darstellung der Loesungsmethoden fuer die Bilanzgleichungen der einzelnen Prozessstufen ist dabei auf das System Dampfreformierung und CO-Gasreinigung eingegrenzt. Parameter zur energetischen Bewertung der Prozessvarianten werden definiert. Die Methodik fuehrt zur Eingrenzung energetisch optimierter Prozessvarianten. Ihr Hauptziel liegt in der optimalen Nutzung prozessinterner Energie- und Stoffstroeme. Ein zentraler Bestandteil der Methodik ist die graphische Pinch-Methode.

    2011-01-01

    Due to the high atmospheric humidity in sumer and autumn and the water vapor accompanied by workpieces to be coated and their holders, the time required for high vacuum in vacuum chamber is long in the continuous vacuum sputtering process. Thus, the whole production process becomes slow with the reduced utilization rate of productive capacity and increased energy consumption. For this reason, the original vacuum sputtering line was reformed via the ultralow-temperature freezing process with no change of the original layout in the line. As a result, the water vapor in vacuum chamber can be captured and collected quickly so as to acquire the high vacuum required in vacuum chamber, thus attaining the goal for reform.%在连续化真李溅镀生产实践中,由于夏秋两个季节的环境湿度大,加之待镀工件和夹具携带的水蒸气,使得真窄腔体达到要求的高真空时间较长.这样既延缓了生产节拍,降低了设备产能,又加大了能源消耗.在不改变原生产线设备布局的情况下,利用超低温冷冻技术对原生产线进行改造,以实现快速捕集真空腔体内的水气,使真空腔体迅速达到要求的高真空,并取得了良好效果.

  11. Reforming Science and Mathematics Education

    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

    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.

  16. 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.

In November 2007 a mail survey was done in Romanian PA institutions. The opinions showed the necessity of the administrative reforms is accepted mainly as a request of the European Union. The way in which reforms were done is seen as a strenuous process, characterized by low coherence, with many changes of focus and done mainly through enacting new legislation over and over, which led to over-regulation. De-centralization (financial and managerial has still a long way to go, legislative improvement also (especially streamlining rules and procedures, citizens/community is not seen as a real partnership. More optimistic answers are regarding the functioning of local institutions (especially along the organizational culture dimension, which are seen as functioning very well in the context of reforms (a cautionary note should be made – loyalty or subjectivity may have lead to such answers.

    2013-12-01

    Full Text Available Although the Peruvian Agrarian Reform has been a mayor event for the peasant communities of Peru, especially in the Andes, it is barely evoked. It is the case of the community of Llanchu, located in the region of Cusco y in the Province of Calca, even if it has born thanks to the reform. In this paper we will analyse the way people refers to the agrarian reform. We will show that discourses about the past are socially controlled as any other kind of speech in that society. We will also discuss the way this past is engraved in the society and its territory. The ancient categories former to the reform are then still in use today even if they are expressed in new words. We will finally discuss the fact that the forgetfulness of the reform makes this community appear like a long-date one. The main question raised here is “what is supposed to be a peasant community today in the Peruvian Andes?” Is that so important to show a social unity and a historical continuity? This point is especially crucial today, as those populations entered in a process of ethnicization.

    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.

    基于生命尊严所蕴含的绝对性和神圣不可侵犯性,死刑废除论的思想得以兴起和发展。世界上死刑趋于减少和执行方式趋于人道,折射出生命价值地位的上升和生命尊严观念与现代文明之间的契合。本世纪初兴起于中国大地的死刑存废之争是一次现代化的思想洗礼,尽管争论的结果是我国尚不具备废除死刑的条件,但争论本身以及此后采取的限制死刑、改革死刑执行方式的做法,使我国民众受到一次生命尊严理念的深刻教育。%Based on the absoluteness and sanctity of life dignity,the dispute over the existence and abolish-ment of death penalty has sprung up.The death penalty around the world tends to decrease and its executive way turned humane,reflecting the nobler position of life value and the integration of human dignity and modern civilization.The dispute over the existence and the abolishment of death penalty in China was a thought baptism in the 21st century.Though it is unlikely to abolish death penalty completely in China at the present time,this dispute will finally become a useful education experience about life dignity for the people in the restriction and reformation of death penalty.

  12. Reformers for the production of hydrogen from methanol and alternative fuels for fuel cell powered vehicles

    The objective of this study was (i) to assess the present state of technology of reformers that convert methanol (or other alternative fuels) to a hydrogen-rich gas mixture for use in a fuel cell, and (ii) to identify the R&D needs for developing reformers for transportation applications. Steam reforming and partial oxidation are the two basic types of fuel reforming processes. The former is endothermic while the latter is exothermic. Reformers are therefore typically designed as heat exchange systems, and the variety of designs used includes shell-and-tube, packed bed, annular, plate, and cyclic bed types. Catalysts used include noble metals and oxides of Cu, Zn, Cr, Al, Ni, and La. For transportation applications a reformer must be compact, lightweight, and rugged. It must also be capable of rapid start-up and good dynamic performance responsive to fluctuating loads. A partial oxidation reformer is likely to be better than a steam reformer based on these considerations, although its fuel conversion efficiency is expected to be lower than that of a steam reformer. A steam reformer better lends itself to thermal integration with the fuel cell system; however, the thermal independence of the reformer from the fuel cell stack is likely to yield much better dynamic performance of the reformer and the fuel cell propulsion power system. For both steam reforming and partial oxidation reforming, research is needed to develop compact, fast start-up, and dynamically responsive reformers. For transportation applications, steam reformers are likely to prove best for fuel cell/battery hybrid power systems, and partial oxidation reformers are likely to be the choice for stand-alone fuel cell power systems.

  6. The 'reformation' of counselling

    Directory of Open Access Journals (Sweden)

    G.A. Lotter

    2001-08-01

    Full Text Available Although the Reformation took place some four hundred years ago, one area in which reformation is really needed today is the counselling of people. Since Wilhelm Wundt started the “study of the mind” in 1879, William James and Sigmund Freud followed and secular psychology gradually has developed to take the “front seat”; hence moving Biblical counselling, which has been practised since the times of the New Testament, to the “back burner”. This development had been going on for the greater part of the 20th century, up to the publication of Competent to Counsel by Jay E. Adams in 1970. In the model for counselling suggested by Adams, the principles of the Reformation of the sixteenth century, Soli Deo Gloria, Soli Scriptura, Soli Fidei, Sola Gratia, etc. were again implemented in assisting and counselling people with personal and interpersonal problems. The epistomological and anthropological approach of secular psychology differs radically from that of Biblical principles, thus necessitating a new “reformation” of counselling. Within this new form counselling, inter alia, implies the following: the Word of God has its rightful place, sin has to be taken seriously and the work of the Holy Spirit should be recognised. In this article it is proposed that the “reformation” of counselling was started by scholars with a Biblical Reformational approach and that this method of counselling followed the parameters of the Reformation of the sixteenth century. This “reformation” developed into a new direction in counselling and still continues today with fascinating new frontiers opening up for Biblical counselling.

  10. The Possibility of Reform: Micropolitics in Higher Education

    2002-04-01

    Full Text Available The purpose of this case study was to examine the restructuring of an institution of higher education's teacher preparation program and to assess the possibility for systemic reform.  Although teacher education represents a vital link in not only the educational system but in curricular reform, the increased expectations for educational reform made this institution unavoidably more political.  These conditions meant that the study of micropolitics was critical to understanding how organizations change or fail to initiate change.  Any effort to reform an organization requires examination of the reform effort's underlying assumptions, social and historical context for the reform, and how reform is congruent with the values, ideologies, and goals of the constituents. This case will serve those critiquing reform and also takes the extant K-12 micropolitical research into the heretofore unstudied realm of higher education therefore impacting reform at the post secondary level. Schools are vulnerable to a host of powerful external and internal forces.  They exist in a vortex of government mandates, social and economic pressures, and conflicting ideologies associated with administrators, faculty, and students. Efforts to reform school are confounded by competing political agendas.  At the very least, reform is an opportunity for political action by people in power.  While literature regarding effective schools touts strong leadership and shared values, accomplishing school reform continues to remain problematic. Despite the widespread interest and infusion of resources for restructuring teacher education, the history of educational reform shows that initiatives have often failed.   The study began with the micropolitical hypothesis that the educational system comprises diverse constituencies with differing ideologies regarding schooling.  Qualitative methodology was employed to portray intra-organizational processes, to provide concrete

    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 In 2010, the United States adopted its first-ever comprehensive set of health system reforms in the Affordable Care Act (ACA. Implementation of the law, though politically contentious and controversial, has now reached a stage where reversal of most elements of the law is no longer feasible. The controversial portions of the law that expand affordable health insurance coverage to most U.S. citizens and legal residents do not offer any important lessons for the global community. The portions of the law seeking to improve the quality, effectiveness, and efficiency of medical care as delivered in the U.S., hold lessons for the global community as all nations struggle to gain greater value from the societal resources they invest in medical care for their peoples. Health reform is an ongoing process of planning, legislating, implementing, and evaluating system changes. The U.S. set of delivery system reforms has much for reformers around the globe to assess and consider.

  3. Estimate of resources required for a meaningful reform of education

    CERN Document Server

    Glazek, Stanislaw D

    2012-01-01

    A simple estimate in terms of currency units shows that a meaningful educational reform process can be launched and sustained over many generations of teachers with support of parents of students. In the estimate, the steady inflow of resources from parents provides support for advanced studies by teachers. Not to waste the resources on spurious activities, the estimated inflow proceeds directly from the parents as clients to the providers of required reform program. The providers are the experts in various disciplines who excel in helping teachers become great. Their services to teachers are ultimately assessed by parents on the basis of changes in behavior of children. The resulting reform program grows slowly from small seeds. The running cost of the reform process to parents appears surprisingly low while its development leads to the desired changes over time.

    2005-03-01

    This work analyzes the neoliberal health sector reforms that have taken place in Latin America, the preparation of health care workers for the reforms, the reforms' impacts on the workers, and the consequences that the reforms have had on efficiency and quality in the health sector. The piece also looks at the process of formulating and implementing the reforms. The piece utilizes secondary sources and in-depth interviews with health sector managers in Bolivia, Colombia, Costa Rica, the Dominican Republic, Ecuador, El Salvador, and Mexico. Neoliberal reforms have not solved the human resources problems that health sector evaluations and academic studies had identified as the leading causes of health system inefficiency and low-quality services that existed before the reforms. The reforms worsened the situation by putting new pressures on health personnel, in terms of both the lack of necessary training to face the challenges that came with the reforms and efforts to take away from workers the rights and benefits that they had gained during years of struggles by unions, and to replace them with temporary contracts, reduced job security, and lower benefits. The secrecy with which the reforms were developed and applied made workers even more unified. In response, unions opposed the reforms, and in some countries they were able to delay the reforms. The neoliberal reforms have not improved the efficiency or quality of health systems in Latin America despite the resources that have been invested. Nor have the neoliberal reforms supported specific changes that have been applied in the public sector and that have demonstrated their ability to solve important health problems. These specific changes have produced better results than the neoliberal reforms, and at a lower cost.

    2002-02-01

    , individual or collective collaboration between the population and health services has been promoted by several philosophies and concepts with different aims: from the search for collaboration with the general public to broaden public health system coverage to the promotion of the creation of mechanisms that would allow society to exercise control over these services' performance. Nevertheless, for the public to be involved with these services, several factors concerning both the services themselves and the population, need to converge. Although the theoretical frameworks that have encouraged social participation throughout the history of the development of health systems differ considerably, their practical implementation shares many common elements in all periods, from participation as a means of obtaining certain objectives to being an end in itself, as a democratic process. This can also be applied to the current promotion of social participation policies in the context of health care reforms, which are analyzed using Colombia and Brazil as examples.

    Methane reforming in steam (SR), auto-thermal (ATR) and partial oxidation (POX) conditions over Ni/Ba-Ce{sub 0.9}-Y{sub 0.1} catalyst was investigated in the temperature range 500-700 C. Catalyst presents a satisfying activity in POX condition only. BCY carrier was not stable in the presence of CO{sub 2} and, irrespective of reaction conditions, it reacts with CO{sub 2} giving rise to the formation of BaCO{sub 3} and CeO{sub 2}. The very low activity observed in SR conditions was due to the negative role exerted by water strongly absorbed on catalyst surface, limiting so the accessibility and reduction state of Ni active sites. In POX condition catalyst is active and satisfying H{sub 2} yield can be reached by operating at T = 700 C. A significant reduction of coke formation was observed by operating in POX at 700 C. On the contrary, in ATR condition at the same reaction temperature huge amount of filamentous coke was observed. (author)

    The methane autothermal reforming in the present of oxygen was studied over cerium-and zirconium-promoted Ni/SiO2 catalysts in a fluidized bed reactor. The addition of CeZrO2 resulted in a significant improvement in the initial activity of the catalysis as well as an in-crease in the stability. The long-term activity of the promoted catalyst was dependent upon the rapid redox properties between the oxidative zone and the reductive zone in a fluidized bed reactor. H2 temperature-programmed reduction (H2-TPR) and temperature-progranmaed sur-face reaction (TPSR) studies demonstrated that addition of the CeZrO2 resulted in an increase in the reducibility and oxygen transfer ability of the support, Ni/Ce0.5ZrO0.5O2-SiO2 showed improved redox properties compared with Ni/SiO2 due to a low-temperature reduction. X-ray diffraction (XRD) of the fresh and spent catalysts showed that the promoter enhanced the nickel dispersion and retarded metal particle growth during reaction at high temperature, and surface Ni was gradually oxidized by remaining O2, leading to Ni deactivation.

    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.

    The present teaching of tax law, which has many problems: complex and changeful teaching contents, unitary teaching methods, stereotypical textbook systems, and unreasonable knowledge structure of the teachers’, is hard to meet the requirements for the cultivation of applica-tion-oriented finance and economics talents. The reason is that the teaching of tax law does not implement the idea of organizing teaching activities based on business process,and comply with the consistent principle of working, teaching and learning. By updating the teaching ideas, integrating the teaching contents, redesigning the teaching methods, rewriting textbook of tax law, and cultivating“double-qualified”teachers, the solution is to teach students based on the process of taxation in accordance of their aptitudes to develop wel-liked finance and economics talents.%由于目前税法教学存在教学内容繁杂多变、教学方式单一、教材体系老套、师资知识结构不合理等问题,难以满足社会对应用型财经人才的培养要求。究其原因是税法教学没有贯彻基于税收业务流程组织教学的理念,没有遵循“工作怎么做,课堂怎么教,学生怎么学”的原则。改变这一现状的出路在于:基于税务流程,更新教学理念、整合教学内容、设计教学方法、重新编写教材、培养“双师型”师资,因材施教,才有可能培养适销对路的财经人才。

    Carroll E. Bronson

    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.

    2002-01-01

    Full Text Available 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.

  16. Leveraging Fuel Subsidy Reform for Transition in Yemen

    Directory of Open Access Journals (Sweden)

    Olivier Ecker

    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.

  17. Framing divorce reform: media, morality, and the politics of family.

    Science.gov (United States)

    Adams, Michele; Coltrane, Scott

    2007-03-01

    No-fault statutes changed divorce from an adversarial system pitting victims against victimizers, with the state acting as enforcer of marital norms, to a private decision between unhappily married but legally blameless partners. Divorce reform following no-fault primarily focused on making divorce more fair for the parties involved. Over the last several decades, divorce reform has transitioned from making divorce better to making marriage healthier. The good divorce has slipped from policy attention, elevating the potential for restigmatization of divorced couples and their children. We trace the trajectory of media framing of divorce reform discourse in three general circulation newspapers from the start of the no-fault revolution, noting how media framing parallels and naturalizes the transition in divorce reform policy. We conclude by observing the prevalence of divorce and the related need for therapists to be cognizant of this naturalization process, thereby keeping the good divorce as a goal for those who desire to end their marriages.

  19. 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

  20. Public Administration reforms and results

    Directory of Open Access Journals (Sweden)

    Gunnar Helgi Kristinsson

    2014-12-01

    Full Text Available Research on administrative reforms during the past thirty years indicates that reform efforts of countries differ. The Anglo Saxon states were at the forefront of the New Public Management movement while countries on mainland Europe were more hesitant and moved further towards the Neo-Weberian state. Academics have tried to explain different reform efforts within countries by looking at political, historical and cultural issues, values and economic factors to name just a few. Three hypotheses are put forward to explain reform efforts in different states. This research involves analysing the implementation of two different reform trends, New Public Management and the Neo-Weberian tradition. The analysis indicates that countries vary in their commitment to reform rather than in the emphasis on either New Public Management or the Neo-Weberian State. Decentralization, clear objectives and consultation with communities and experts are closely related to national reform efforts. However, Iceland does distinguish itself from Europe and the Nordic countries. The analysis reveals that although decentralization is high in the Icelandic system, autonomy of agencies does not have a strong relation to a varied use of administrative instruments. The second part of the article focuses on the results and achievements of reform programmes. The achievement of reform programmes are examined in relation to theories of bounded rationality, street level bureaucracy (bottom up and consensus decision making. Three hypotheses are presented and tested to explain what causes reforms programmes to be successful in some countries and not in others. The analysis reveals that countries are more likely to succeed if bounded rationality is applied with careful preparation and when stakeholders are consulted.

    2013-01-01

    In this paper a system combining a diesel reformer using catalytic partial oxidation (CPOX) with the Solid Oxide Fuel Cell (SOFC) for Auxiliary Power Unit (APU) applications is modeled with respect to the cooling effect provided by internal reforming of methane in anode gas channel.A model mixture consisting of 80% n-hexadecane and 20% 1-methylnaphthalin is used to simulate the commercial diesel.The modelling consists of several steps.First,equilibrium gas composition at the exit of CPOX reformer is modelled in terms oxygen to carbon (O/C) ratio,fuel utilization ratio and anode gas recirculation.Second,product composition,especially methane content,is determined for the methanation process at the operating temperatures ranging from 500 ℃ to 520 ℃.Finally,the cooling power provided by internal reforming of methane in SOFC fuel channel is calculated for two concepts to increase the methane content of the diesel reformate.The results show that the first concept,operating the diesel reformer at low O/C ratio and/or recirculation ratio,is not realizable due to high probability of coke formation,whereas the second concept,combining a methanation process with CPOX,can provide a significant cooling effect in addition to the conventional cooling concept which needs higher levels of excess air.

    The heat transfer effects on a methanol-steam reforming (MSR) process are numerically investigated using a circular reformer with a partially (referred to as the wall-coated reformer) or entirely filled catalyst layer (referred to as the packed-bed reformer). The catalyst layer is formed by packing CuO/ZnO/Al{sub 2}O{sub 3} catalyst particles with a certain porosity and permeability. The fluid flow characteristics are strongly affected by the catalyst-layer thickness. As a consequence, the heat and mass transfer also depend on the catalyst-layer thickness. Under heat supplied by wall heat flux conditions, it is found that higher reforming temperature can be obtained for the wall-coated reformer compared with the packed-bed reformer. This results in the wall-coated reformer having a better methanol conversion efficiency compared with the packed-bed reformer. Based on our study, the minimum heat transfer coefficient, maximum methanol conversion and maximum carbon monoxide production are obtained when the catalyst-layer thickness is 90% of the reformer radius.

  11. A reforming accountability: GPs and health reform in New Zealand.

    Science.gov (United States)

    Jacobs, K

    1997-01-01

    Over the last ten years or so, many countries have undertaken public sector reforms. As a result of these changes, accounting has come to play a more important role. However, many of the studies have only discussed the reforms at a conceptual level and have failed to study how the reforms have been implemented and operated in practice. Based on the work of Lipsky (1980) and Gorz (1989), it can be argued that those affected by the reforms have a strong incentive to subvert the reforms. This prediction is explored via a case study of general practitioner (GP) response to the New Zealand health reforms. The creation of Independent Practice Associations (IPAs) allowed the State to impose contractual-accountability and to cap their budget exposure for subsidies. From the GP's perspective, the IPAs absorbed the changes initiated by the State, and managed the contracting, accounting and budgetary administration responsibilities that were created. This allowed individual GPs to continue practising as before and provided some collective protection against the threat of state intrusion into GP autonomy. The creation of IPAs also provided a new way to manage the professional/financial tension, the contradiction between the professional motivation noted by Gorz (1989) and the need to earn a living.

  12. Implementing Lean Health Reforms in Saskatchewan

    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.

  13. Influence of Steam Reforming Catalyst Geometry on the Performance of Tubular Reformer – Simulation Calculations

    Directory of Open Access Journals (Sweden)

    Franczyk Ewelina

    2015-06-01

    Full Text Available A proper selection of steam reforming catalyst geometry has a direct effect on the efficiency and economy of hydrogen production from natural gas and is a very important technological and engineering issue in terms of process optimisation. This paper determines the influence of widely used seven-hole grain diameter (ranging from 11 to 21 mm, h/d (height/diameter ratio of catalyst grain and Sh/St (hole surface/total cylinder surface in cross-section ratio (ranging from 0.13 to 0.37 on the gas load of catalyst bed, gas flow resistance, maximum wall temperature and the risk of catalyst coking. Calculations were based on the one-dimensional pseudo-homogeneous model of a steam reforming tubular reactor, with catalyst parameters derived from our investigations. The process analysis shows that it is advantageous, along the whole reformer tube length, to apply catalyst forms of h/d = 1 ratio, relatively large dimensions, possibly high bed porosity and Sh/St ≈ 0.30-0.37 ratio. It enables a considerable process intensification and the processing of more natural gas at the same flow resistance, despite lower bed activity, without catalyst coking risk. Alternatively, plant pressure drop can be reduced maintaining the same gas load, which translates directly into diminishing the operating costs as a result of lowering power consumption for gas compression.

  14. Systemic Reform in a Federated System:Los Angeles at the Turn of the Millennium

    David Menefee-Libey

    2004-10-01

    Full Text Available I synthesize some of the lessons we have learned about systemic school reform in order and derive two explicit hypotheses about when such reforms are likely to be more and less successful. The first hypothesis focuses on program implementation: to achieve success, any systemic reform must overcome challenges at each stage of the policy-making process, from agenda-setting to policy choice to implementation. The second hypothesis focuses on the federated nature of education policymaking in the United States: any successful systemic reform must offer a program that aligns local efforts with state and sometimes federal policy. I derive and test more specific hypotheses related to recent systemic reform efforts in the Los Angeles region—especially the Los Angeles Annenberg Metropolitan Project, or LAAMP—which ran from 1995 through 2001. The case confirms the hypotheses and enables a clearer understanding of systemic school reform.

    Frost, Ray L; Musumeci, Anthony W

    2006-10-01

    Thermally activated hydrotalcite based upon a Zn/Al hydrotalcite with carbonate in the interlayer has been used to remove nitrate anions from an aqueous solution resulting in the reformation of a hydrotalcite with a mixture of nitrate and carbonate in the interlayer. X-ray diffraction of the reformed hydrotalcites with a d(003) spacing of 7.60 A shows that the nitrate anion is removed within a 30 min period. Raman spectroscopy shows that two types of nitrate anions exist in the reformed hydrotalcite (a) nitrate bonded to the 'brucite-like' hydrotalcite surface and (b) aquated nitrate anion in the interlayer. Kinetically the nitrate is replaced by the carbonate anion over a 21 h period. Two types of carbonate anions are observed. This research shows that the reformation of a thermally activated hydrotalcite can be used to remove anions such as nitrate from aqueous systems.

  4. Diversity in Intercultural Educational Reforms

    Directory of Open Access Journals (Sweden)

    Hector Muñoz Cruz

    2002-11-01

    Full Text Available This study analyzes the implications of contemporary linguistic and cultural diversity concerning educational theory from three different perspectives: intercultural bilingual-education proposals; the demographical view in relation to language distribution and functionality; and the analysis of diversity within the framework of linguistic and cultural conflict. In recent searches for the meanings of diversity, sociolinguistic investigations have postulated that the consequences of the loss of diversity and its replacement by uniformity will be reflected in three important dimensions of social life: first, changes in communicative function and in cultural continuity; second, a more intense concentration of rationality or reflection on dominant linguistic and cultural models; and third, an intensification of the processes of diversification and specialization of subjects’ cultural skills pertaining to the needs of global projects. Multiculturalism and inequalities have erupted with such an impact on the sociopolitical platforms of global, national and ethnic projects that they have changed diversity and multidirectionality into fascinating but conflictive disclosures. Little by little these notions are giving support to a citizenship parameter for the society of the near future, when new national problems will arise, and new solutions, charged with participation and democratic meaning, will have to be devised. At the moment, the phenomena of interculturality, bilingualism and ethnodiversity are creating new parameters for the discussion of educational reform.

  5. 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

    2010-02-15

    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

  7. Energy-Efficient Routes for the Production of Gasoline from Biogas and Pyrolysis Oil—Process Design and Life-Cycle Assessment

    Science.gov (United States)

    2017-01-01

    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

    We address four main areas in which graduate quantum mechanics education in the U.S. can be improved: course content; textbook; teaching methods; and assessment tools. We report on a three year longitudinal study at the Colorado School of Mines using innovations in all four of these areas. In particular, we have modified the content of the course to reflect progress in the field in the last 50 years, use modern textbooks that include such content, incorporate a variety of teaching techniques based on physics education research, and used a variety of assessment tools to study the effectiveness of these reforms. We present a new assessment tool, the Graduate Quantum Mechanics Conceptual Survey, and further testing of a previously developed assessment tool, the Quantum Mechanics Conceptual Survey (QMCS). We find that graduate students respond well to research-based techniques that have previously been tested mainly in introductory courses, and that they learn a great deal of the new content introduced in each ve...

  20. Biomass to hydrogen via fast pyrolysis and catalytic steam reforming

    Energy Technology Data Exchange (ETDEWEB)

    Chornet, E.; Wang, D.; Montane, D. [National Renewable Energy Lab., Golden, CO (United States)] [and others

    1995-09-01

    Fast pyrolysis of biomass results in a pyrolytic oil which is a mixture of (a) carbohydrate-derived acids, aldehydes and polyols, (b) lignin-derived substituted phenolics, and (c) extractives-derived terpenoids and fatty acids. The conversion of this pyrolysis oil into H{sub 2} and CO{sub 2} is thermodynamically favored under appropriate steam reforming conditions. Our efforts have focused in understanding the catalysis of steam reforming which will lead to a successful process at reasonable steam/carbon ratios arid process severities. The experimental work, carried out at the laboratory and bench scale levels, has centered on the performance of Ni-based catalysts using model compounds as prototypes of the oxygenates present in the pyrolysis oil. Steam reforming of acetic acid, hydroxyacetaldehyde, furfural and syringol has been proven to proceed rapidly within a reasonable range of severities. Time-on-stream studies are now underway using a fixed bed barometric pressure reactor to ascertain the durability of the catalysts and thus substantiate the scientific and technical feasibility of the catalytic reforming option. Economic analyses are being carried out in parallel to determine the opportunity zones for the combined fast pyrolysis/steam reforming approach. A discussion on the current state of the project is presented.

  1. Let's make a deal: trading malpractice reform for health reform.

    Science.gov (United States)

    Sage, William M; Hyman, David A

    2014-01-01

    Physician leadership is required to improve the efficiency and reliability of the US health care system, but many physicians remain lukewarm about the changes needed to attain these goals. Malpractice liability-a sore spot for decades-may exacerbate physician resistance. The politics of malpractice have become so lawyer-centric that recognizing the availability of broader gains from trade in tort reform is an important insight for health policy makers. To obtain relief from malpractice liability, physicians may be willing to accept other policy changes that more directly improve access to care and reduce costs. For example, the American Medical Association might broker an agreement between health reform proponents and physicians to enact federal legislation that limits malpractice liability and simultaneously restructures fee-for-service payment, heightens transparency regarding the quality and cost of health care services, and expands practice privileges for other health professionals. There are also reasons to believe that tort reform can make ongoing health care delivery reforms work better, in addition to buttressing health reform efforts that might otherwise fail politically.

    2011-05-01

    This study focused on steam gasification and reforming of waste biomass using a reforming catalyst. The purpose of the study was to evaluate the durability of a commercial Ni reforming catalyst and the effect of CaO on the reforming behavior, and to clarify detailed factors of catalytic performance, as well as the effect of operating parameters on the characteristics of produced gas composition. Moreover, catalyst regeneration was carried out and the behavior of catalytic activity based on gas composition was investigated. Using a fluidized bed gasifier and a fixed bed reformer, gasification and reforming of waste biomass were carried out. Commercial Ni-based catalyst and calcined limestone (CaO) were applied to the reforming reaction. Temperature of the gasifier and reformer was almost 1023K. Ratio of steam to carbon in the feedstock [molmol(-1)] and equivalence ratio (i.e., ratio of actual to theoretical amount of oxygen) [-] were set at about 2 and 0.3, respectively. The feed rate of the feedstock into the bench-scale gasifier was almost 15kgh(-1). The results of waste biomass gasification confirmed the improvement in H(2) composition by the CO(2) absorption reaction using the reforming catalyst and CaO. In addition, CaO proved to be especially effective in decreasing the tar concentration in the case of woody biomass gasification. Catalytic activity was maintained by means of catalyst regeneration processing by hydrogen reduction after air oxidation when woody biomass was used as feedstock.

    Yancey, Amy; Stewart, Charles Neal

    2010-05-01

    The current patent landscape in the US has not undergone major legislative reform since 1952. The US Senate version of the most recently proposed patent reform legislation puts forward a number of rule changes that could impact the pharmaceutical industry. Among the bill's major provisions are moving to a first-to-file system, changes to post-grant review and reexamination procedures, and damages reform. Various industries with a stake in patent reform have responded to the proposed changes. The need for balanced reform makes the stakes particularly high for the pharmaceutical industry which must invest a significant amount of time and money in the research and development process in exchange for already abbreviated patent lifetimes due to the lengthy clinical trial process.

    2014-04-01

    This article presents a comparative analysis of the processes leading to health care reform in Argentina and in the USA. The core of the analysis centers on the ideological references utilized by advocates of the reform and the decision-making processes that support or undercut such proposals. The analysis begins with a historical summary of the issue in each country. The political process that led to the sanction of the Obama reform is then described. The text defends a hypothesis aiming to show that deficiencies in the institutional capacities of Argentina's decision-making bodies are a severe obstacle to attaining substantial changes in this area within the country.

  9. 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.

    Full Text Available The demographic situation in the European Union is changing. 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.

  20. 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.

  1. [Human resources for health in Chile: the reform's pending challenge].

    Science.gov (United States)

    Méndez, Claudio A

    2009-09-01

    Omission of human resources from health policy development has been identified as a barrier in the health sector reform's adoption phase. Since 2002, Chile's health care system has been undergoing a transformation based on the principles of health as a human right, equity, solidarity, efficiency, and social participation. While the reform has set forth the redefinition of the medical professions, continuing education, scheduled accreditation, and the introduction of career development incentives, it has not considered management options tailored to the new setting, a human resources strategy that has the consensus of key players and sector policy, or a process for understanding the needs of health care staff and professionals. However, there is still time to undo the shortcomings, in large part because the reform's implementation phase only recently has begun. Overcoming this challenge is in the hands of the experts charged with designing public health strategies and policies.

    1999-01-01

    How does central bank conservatism affect labor market reform? In this paper we examine the economic forces at work. An increase in conservatism triggers two opposite effects. It reduces the inflation bias of discretionary monetary policy and hence the benefits of a reform. It also increases unemployment variability, which increases the precautionary benefits of a reform. In combination, the two effects produce a u-shaped relation between conservatism and labor market reform. An empirical inv...

  4. Oncology payment reform to achieve real health care reform.

    Science.gov (United States)

    McClellan, Mark B; Thoumi, Andrea I

    2015-05-01

    Cancer care is transforming, moving toward increasingly personalized treatment with the potential to save and improve many more lives. Many oncologists and policymakers view current fee-for-service payments as an obstacle to providing more efficient, high-quality cancer care. However, payment reforms create new uncertainties for oncologists and may be challenging to implement. In this article, we illustrate how accountable care payment reforms that directly align payments with quality and cost measures are being implemented and the opportunities and challenges they present. These payment models provide more flexibility to oncologists and other providers to give patients the personalized care they need, along with more accountability for demonstrating quality improvements and overall cost or cost growth reductions. Such payment reforms increase the importance of person-level quality and cost measures as well as data analysis to improve measured performance. We describe key features of quality and cost measures needed to support accountable care payment reforms in oncology. Finally, we propose policy recommendations to move incrementally but fundamentally to payment systems that support higher-value care in oncology.

  5. Higher Education Reforms: Between Centers and Peripheries

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available The main purpose of this article is to offer—within the perspective of the past two decades—a reflection on the higher education reform in the region consisting of Slovenia and seven countries of the so-called Western Balkans. The main question is what are the main characteristics of the higher education reforms in these countries after 1990, and what was their relationship to international processes and developments in the field of higher education policy. In particular, we will focus on the emergence of politicization and privatization of higher education, the implementation of the Bologna Process, and the dichotomy of international norms and local identities. Within the latter, we will discuss the relationship between centers and peripheries in the context of higher education policies. On this basis we will finally critically examine the question whether, in the context of modern development of higher education, peripheral countries now play only the role of a kind of ‘policy colonies’.

  12. 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.

    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

    Experiments were conducted on syngas preparation from dry reforming of methane by carbon dioxide with a DC arc plasma at atmospheric pressure. In all experiments, nitrogen gas was used as the working gas for thermal plasma to generate a high-temperature jet into a horizontal tube reactor. A mixture of methane and carbon dioxide was fed vertically into the jet. In order to obtain a higher conversion rate of methane and carbon dioxide, chemical energy efficiency and fuel production efficiency, parametric screening studies were conducted, in which the volume ratio of carbon dioxide to methane in fed gases and the total flux of fed gases were taken into account. Results showed that carbon dioxide reforming of methane to syngas by thermal plasma exhibited a larger processing capacity, higher conversion of methane and carbon dioxide and higher chemical energy efficiency and fuel production efficiency. In addition, thermodynamic simulation for the reforming process was conducted. Experimental data agreed well with the thermodynamic results, indicating that high thermal efficiency can be achieved with the thermal plasma reforming process.

    Studies have shown that the energy costs associated with plasma fuel reforming can vary depending on the type of plasma generation technique. The reasons for the different energy costs, however, are not yet clear, since different types of plasma reactor lead to not only different plasma conditions but also lead to different reaction conditions that is not relevant to plasma, such as gas residence time, heat and mass flow conditions. This paper presented the results of a parametric study on methane partial oxidation which was conducted to determine the optimal operating conditions and geometrical design of an arc jet plasma fuel reformer. The arc reactor used in this study was designed to control various operating parameters such as arc length, gas residence time, and gas mixing. Two different types of power supply were tested, notably one that produced high voltage with low current, and one that produced relatively low voltage and high current. The effects of these different voltage-current characteristics on gas reforming process were analyzed based on methane conversion rates, selectivity of products, and thermal efficiencies. The study showed that the input power but not the voltage plays an important role in the present partial oxidation process. The gas residence time was also found to be an important factor in controlling the reformer process. 10 refs., 8 figs.

    Full Text Available The reforms of the public sector rank among the most complex problems Croatia has to face in the process of transition and accession to the EU. One of the recent reforms, the Customs Service Reform, offers insights into some of the achieved improvements and may serve as a guideline for reformers in other areas of public management. This research provides evidence of “customer satisfaction” with the functioning of the Croatian Customs System. Conclusions have been drawn based on the responses of 31 forwarders from Istarska County using a 19-item Likert scale. According to their opinion, services have improved in several aspects during the past few years, and accordingly the results can be interpreted as an indication of success of reform efforts.

    Full Text Available This paper sets up two competing frameworks to assess the evidence of the CAP reforms of the 1980s and 1990s. The two frameworks differ in the degree of prominence given to interest groups in affecting CAP decisions. The paper concludes that the most important mechanism behind CAP reforms is the interaction of EU institutions and member state governments. Interest groups, at national or EU-level, have limited influence on the reform process. The paper does not claim to have developed a new theory of CAP reform but rather aims to suggest a direction for the development of a high content theory that is able to account for the differences between episodes of CAP reform as well as the similarities.

    This study established an analytical method for the trace analyses of two phthalate esters, including diethyl phthalate (DEP) and di-n-butyl phthalate (DBP), known as the major constituents of cleanroom micro-contamination detrimental to the reliability of semiconductor devices. Using thermal desorption coupled with a GC-MS system, standard tubes were prepared by delivering liquid standards pre-vaporized by a quasi-vaporizer into Tenax GR tubes for calibration. This method was capable of achieving detection limits of 0.05 microg m(-3) for 0.1 m3 air samples and 0.03 ng cm(-2) for 150-mm wafer surface density. Actual samples collected from a semiconductor cleanroom showed that the concentration of DBP in a polypropylene wafer box (0.45 microg m(-3)) was nearly four times higher than that in the cleanroom environment (0.12 microg m(-3)). The surface contamination of DBP was 0.67 ng cm(-2) for a wafer stored in the wafer box for 24 h. Furthermore, among the three types of heat-resistant O-ring materials tested, Kalrez was found to be particularly suitable for high-temperature processes in semiconductor cleanrooms due to their low emissions of organic vapors. This analytical procedure should serve as an effective monitoring method for the organic micro-contamination in cleanroom environments.

    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

    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.

    2005-01-01

    Full Text Available Abstract Human resources are the most important assets of any health system, and health workforce problems have for decades limited the efficiency and quality of Latin America health systems. World Bank-led reforms aimed at increasing equity, efficiency, quality of care and user satisfaction did not attempt to resolve the human resources problems that had been identified in multiple health sector assessments. However, the two most important reform policies – decentralization and privatization – have had a negative impact on the conditions of employment and prompted opposition from organized professionals and unions. In several countries of the region, the workforce became the most important obstacle to successful reform. This article is based on fieldwork and a review of the literature. It discusses the reasons that led health workers to oppose reform; the institutional and legal constraints to implementing reform as originally designed; the mismatch between the types of personnel needed for reform and the availability of professionals; the deficiencies of the reform implementation process; and the regulatory weaknesses of the region. The discussion presents workforce strategies that the reforms could have included to achieve the intended goals, and the need to take into account the values and political realities of the countries. The authors suggest that autochthonous solutions are more likely to succeed than solutions imported from the outside.

    The article examines various healthcare systems reform projects in Canada and some Canadian provinces and reveals some tendencies in governance renewal. The analisis is based on the hypothesis that reform is an exercise aiming at the renewal of governance conception and practices. In renewing governance, reform leaders hope to use adequate and effective levers to attain announced reform objectives. The article shows that the conceptions and operational modalities of governance have changed over time and that they reveal tensions inherent to the transformation and legitimation process of public healthcare systems. The first section discusses the relationships between reform and change. The second section defines the conception of gouvernance used for the analisis. Based on a content analisis of the various reform reports, the third section reveals the evolution of the conception of governance in healthcare systems in Canada. In order to expose the new tendencies, ideologies and operational principles at the heart of the reform projects are analysed. Five ideologies are identified: the democratic ideology, the "population health" ideology, the business ideology, the managerial ideology and the ideology of equity and humanism. This leads to a discussion on the dominant influence of the managerial ideology in the current reform projects.

    Francisco Mardones-Restat

    2006-12-01

    Full Text Available The authors claim that the critical health reform in Chilean history was the establishment of the National Health Service (NHS in 1952. The development of modern Chilean health care since the end of the 19th century is discussed both in terms of the prevailing health situation and the subsequent evolution of institutions and policies, with an emphasis on the social and political conditions that led to the creation of the NHS in 1952. From this analysis and from a comparison of infant mortality rates among Latin American countries during the same period, the authors infer that the 1952 health reform was the social and political benchmark that allowed Chile to exhibit the relatively favorable health situation it still enjoys. Using Cavanaugh's scheme, it is clear that the "first-generation reform" was the reform imposed by the military regime in the early 1980s, which aimed to change the orientation of the health system. Similarly, the "second-generation reform" was that implemented by the democratic administrations of the early 1990s to reverse the harm done by their military predecessors. The rapid aging of the population and the advent of new technologies pose a challenge to the insurance system's coverage capacity and threaten the sustainability of all health systems. The implementation of universal, comprehensive, collective health systems, managed under the most integrated authority political conditions will allow, is emphasized as an appropriate solution for developed and developing countries alike.Los autores sostienen que la reforma de salud crítica en la historia chilena consistió en el establecimiento del Servicio Nacional de Salud (SNS en 1952.

    Industrial reform in China truly embodies the rich content and hard experience of exploration along the path of socialism with Chinese characteristics. At the first stage of industrial reform,a thought revolution was started,which laid the foundation for the development of the market economy,i.e. "to get away from poverty,we have to help ourselves and pursue self-interests". Society then began to realize that the action of individuals and enterprises to pursue income,profit and wealth was not only a proper and rational behavior of discrete entities,but also a reasonable behavior bene cial to society. This profound thought revolution played a decisive role in the transformation from a planned to market economy. At the second stage of industrial reform,some bold assaults were launched on every aspect of the planned economy,while the socialist market economy was identified as the objective of system reform. In this process,Chinese industry courageously,boldly and confidently moved towards an open market economy. As a result,China can now proclaim to the world:"we are not afraid of market competition,but rather,we look forward to it!" At the third stage of industrial reform,the focus has shifted from resolving issues of the transition from a planned to market economy into addressing common institutional and policy issues facing countries worldwide with regard to the effective operation of the market economy. From then on,industrial reform in China was no longer the business of China alone,but the business of the whole world.

    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.

    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.

    Oil is a fundamental component of nationhood in Mexico. The 1938 expropriation of oil resources concluded a process of internal political consolidation and thus became the most important symbol of nationalism. Mexico has been undergoing a process of economic reform that has altered the country`s economic structure and has subjected it to international competition. Oil in particular and energy in general have been left untouched. There is recognition that without an equal reform of the energy industry, the potential for success will be significantly limited. While the Constitution allows private investment in the industry--with the exception of the resource properties themselves--the Regulatory Law bans any private participation. Because of its political sensitivity, however, amending the law in order to reform the oil industry will necessitate a domestic initiative rather than foreign pressure. In this perspective, NAFTA served to slow and postpone the reform of the industry, rather than the opposite. Once NAFTA is well in place, the industry will have to face competition.

Our main objective with this research is twofold: to analyze why and how local public administration uses strategic planning as a managerial tool for managing change (reform, and to identify whether the planning efforts display a specifi c reform pattern. We employed a quantitative methodology – online survey – to collect data on the strategic planning process at the local level in Romania, with a specifi c framework for the strategic profi le (Hinţea, 2015 and another three dimension model – NPM, NWS, NPG1 – for the reform component (Pollitt and Bouckaert, 2011. Our analysis indicates that over 70% of strategic planning efforts are done because it is a mandatory condition for accessing EU funds. Major issues concern implementation, monitoring and evaluation with only around a third of organizations having a formal body responsible for this. Although the process has mixed characteristics, NWS type elements are more common/preferred, while NPM seem least common/preferred by local authorities

    Aqueous Phase Reforming (APR) has during the recent years emerged as a potent, alternative means of processing raw materials of biological origin to component suitable as chemicals and fuel components. In contrary to e.g. steam reforming, aqueous phase reforming bares the promise of lower temperatures in processing which gives rise to potential of reduced energy consumption in the upgrading process itself. Aqueous phase reforming was studied over Pt/Al2O3 at 225 C. Stable catalyst performance and high selectivity was observed. Upon a comparison of two 'bio-alcohols', bio-ethanol and Sorbitol (a sugar alcohol), the latter one is a better feedstock from overall energy utilization viewpoint but the use of it results in a broad range of products. Interestingly, in the case of sorbitol-ethanol mixtures, an improvement in the hydrogen yield was observed. (author)

    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.

    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 Intercountry adoption (ICA is a relatively common practice. Since its contemporary conception during the Second World War, approximately one million children have been adopted internationally. Controversy surrounding ICA includes ideas about human rights and notions of child rescue in the context of major reform to prevent child sales and abduction under the Hague Convention on Intercountry Adoption. Social work, as a discipline, is a central player in ICA practices, and at least, one historian asserts that social work academic literature is scant on the topic of problematic practice and reforms. A review of the social work literature was conducted, and four thematic areas emerged in the 87 manuscripts reviewed: (a social policy; (b exploitation, social justice, ethics, and human rights; (c clinical perspectives to include identity, child development, and family transition; and (d child welfare practices. Results indicate a small but robust body of social work literature, and highlights are presented as well as analysis indicating methodical trends.

    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.

    The paper discusses the expansion of the universal health coverage (UHC) in Taiwan through the establishment of National Health Insurance (NHI), and the fiscal crisis it caused. Two key questions are addressed: How did the NHI gradually achieve universal coverage, and yet cause Taiwanese health spending to escalate to fiscal crisis? What measures have been taken to reform the NHI finance and achieve moderate success to date? The main argument of this paper is that the Taiwanese Government did try to implement various reforms to save costs and had moderate success, but the path-dependent process of reform does not allow increasing contribution rates significantly and thereby makes sustainability challenging.

    We describe changes in a physics teacher's pedagogy and cultural awareness that resulted from her students' involvement in reforming their classroom. For this case study, we examined a veteran high school teacher's semester-long use of CMPLE (the Cogenerative Mediation Process for Learning Environments) in her Modeling Instruction classroom. CMPLE is a formative intervention designed to help students and instructors collaborate to change classroom dynamics, based on how closely the environment matches their learning preferences. Analysis of classroom videos, interviews, and other artifacts indicates that adapting the environment to align with the preferences of that shared culture affected the instructor in complex ways. We will trace her teaching practices and her self-described awareness of the culture of learning, to highlight notable changes. The teacher espoused deeper understanding of her students' physics learning experience, which she gained from including students in responding to their own individual and collective learning preferences.

  12. 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 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.

    Small and medium size reformers that run on widely available Liquefied Petroleum Gas (LPG, containing mostly the propane) can provide Synthesis Gas (or Hydrogen extracted from it) to some Fuel Cell powered cars, boats, homes, farms etc. reducing therefore costs of the pure Hydrogen distribution. We contribute to such idea realization through our simply, plasma-assisted reformer avoiding a need of poison resistant catalysts or prior LPG desulfurizer. In fact, any level of sulfur in LPG is accepted for our non-catalytic reformer based on high-voltage discharges (called GlidArc). The discharges catalytically assist the exothermic partial oxidation process. This assistance takes back less than 2% of the Lower Heating Value (LHV) of produced SynGas. Recycling such a small portion of the energy is therefore an acceptable compromise. The unique oxidant source is air. This contribution presents our expanded tests with commercial LPG in a 1-L reactor working at atmospheric pressure. At a 0.1 kW electric power assistance we produce a Nitrogen-diluted SynGas containing up to 45% of H{sub 2}+CO at the output flow rate corresponding up to 2.7 m3(n)/h of pure H{sub 2}+CO mixture that is equivalent to LHV output power of 8.6 kW. The LPG is totally reformed at 73% energetic efficiency and at the total absence of soot. (authors)

    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.

    2010-02-01

    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.

    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 mared 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.

    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.

    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{sub 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{sup 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{sub 2} (CO{sub 2} reforming) using the out-of-pile test facility is also being considered. In recent years, catalytic reforming of natural gas with CO{sub 2} to synthesis gas (CO and H{sub 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{sub 2} reforming when the steam reforming process is adopted in the out-of-pile test. Numerical analysis of CO{sub 2} reforming and reforming of natural gas with CO{sub 2} and steam (CO{sub 2}+H{sub 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

    Fuel processors for on-board hydrogen production have to meet numerous technical demands. They should be efficient, compact and lightweight, capable of different loads and able to perform cold start ups. In this paper, the recirculation of reformate is proposed as a means of efficiency enhancement. Different system configurations based on this idea are introduced and simulated. The resulting effect on the system's efficiency, the water balance as well as the impact of recirculation on the system's volume and weight are discussed. (author)

  15. Public service or commodity goods? Electricity reforms, access, and the politics of development in Tanzania

    Science.gov (United States)

    Ghanadan, Rebecca Hansing

    Since the 1990s, power sector reforms have become paramount in energy policy, catalyzing a debate in Africa about market-based service provision and the effects of reforms on access. My research seeks to move beyond the conceptual divide by grounding attention not in abstract 'market forces' but rather in how development institutions shape energy services and actually practice policy on the ground. Using the case of Tanzania, a country known for having instituted some of the most extensive reforms and a 'success story' in Africa, I find that reforms are creating large burdens and barriers for access and use of services, including: increasing costs, enforcement pressures, and measures to impose 'market' discipline. However, I also find that many of the most significant outcomes are not found in direct 'market' changes, but rather how reforms are selective, partial, and shaped by the wider needs and claims of the institutions driving reforms, so that questions of how reforms are implemented, how they are measured, and who tells the story become as important as the policies themselves. Using a multiple-arenas framework, including (i) a household and community level study of urban energy conditions, (ii) a study of service and management conditions at the national electric utility, (iii) an examination of the international policy process, and (iv) a study of the history of electricity services across colonial, post-independence, and reform periods, I show that African energy reforms are a technical and political project connecting energy to international investments, donor aid programs, and elite interests within national governments. Energy reforms also involve fundamental service changes that are reorganizing how the costs and benefits of energy systems are distributed, allocated, and managed. The effects of reform extend beyond formal services to have wide-reaching repercussions within natural resources, and uneven social dynamics on the ground. These features point

    2002-07-01

    A new methane reforming process based on fluidized catalysts is examined. Alpha-alumina catalysts, which were developed using a wetness technique that produces bulk nickel loadings, were tested under industrial operating conditions in a new Riser Simulator. Studies showed that for methane reforming, the nickel deposited in zeolites is a promising catalyst because it allows for close control of metal dispersion and re-dispersion. When the catalyst was exposed to repeated oxidation and reduction cycles, the nickel dispersions remained stable at 25 per cent for the NaY zeolite and at 15 per cent for the USY zeolite. The catalyst only offers limited use for steam reforming of methane because of the potential collapse of the zeolite structure under steam conditions. If steam reforming of methane is necessary, then nickel on alpha-alumina catalysts should be considered for maximum catalytic activity. The kinetics of dry reforming and steam reforming of methane on a fluidized Ni on Zeolite/alpha-alumina catalyst were studied in the CRED Riser Simulator reactor. Thermodynamic analysis indicates that it is possible to determine operating conditions for coke formation and the conversion of methane over nickel catalysts. The adsorption of both carbon dioxide and methane play a vital role in determining the observed rate dry reforming of methane in the CATFORMER reactor. All parameters were found to be important at the 95 per cent confidence level.

    1991-01-01

    This article is an analysis of the political context of reforms in the production process and in the welfare state. The theories of legitimation and Fordism are criticized for considering the capitalist class the main force behind the reforms. The working class and the process of class struggle are primarily responsible for changes in production and for the establishment of the welfare state. The author then shows that the changes in production and in the state that occurred after World War II were a response to political events triggered by labor's rebellions and capital's need to respond to those rebellions. Post-Fordism and the political practice that derives from it are criticized for their hasty dismissal of class and class practices by the dominated forces in society. The article ends by offering an alternative strategy for change.

  2. Negative Valve Overlap Reforming Chemistry in Low-Oxygen Environments

    Fuel injection into the negative valve overlap (NVO) period is a common method for controlling combustion phasing in homogeneous charge compression ignition (HCCI) and other forms of advanced combustion. When fuel is injected into O2-deficient NVO conditions, a portion of the fuel can be converted to products containing significant levels of H2 and CO. Additionally, other short chain hydrocarbons are produced by means of thermal cracking, water-gas shift, and partial oxidation reactions. The present study experimentally investigates the fuel reforming chemistry that occurs during NVO. To this end, two very different experimental facilities are utilized and their results are compared. One facility is located at Oak Ridge National Laboratory, which uses a custom research engine cycle developed to isolate the NVO event from main combustion, allowing a steady stream of NVO reformate to be exhausted from the engine and chemically analyzed. The other experimental facility, located at Sandia National Laboratories, uses a dump valve to capture the exhaust from a single NVO event for analysis. Results from the two experiments are in excellent trend-wise agreement and indicate that the reforming process under low-O2 conditions produces substantial concentrations of H2, CO, methane, and other short-chain hydrocarbon species. The concentration of these species is found to be strongly dependent on fuel injection timing and injected fuel type, with weaker dependencies on NVO duration and initial temperature, indicating that NVO reforming is kinetically slow. Further, NVO reforming does not require a large energy input from the engine, meaning that it is not thermodynamically expensive. The implications of these results on HCCI and other forms of combustion are discussed in detail.

    We model the labor market impact of the key provisions of the national and Massachusetts "mandate-based" health reforms: individual mandates, employer mandates, and subsidies. We characterize the compensating differential for employer-sponsored health insurance (ESHI) and the welfare impact of reform in terms of "sufficient statistics." We compare welfare under mandate-based reform to welfare in a counterfactual world where individuals do not value ESHI. Relying on the Massachusetts reform, we find that jobs with ESHI pay $2812 less annually, somewhat less than the cost of ESHI to employers. Accordingly, the deadweight loss of mandate-based health reform was approximately 8 percent of its potential size.

    The development of heat resistant permeation membranes has opened up new possibilities for the conversion of fossil energy resources. In steam reforming of natural gas, such membranes even permit a direct production of hydrogen at high temperatures during the conversion of feed hydrocarbons. Further gas processing, such as required for reformer gas in existing hydrogen production processes, is not necessary. Due to continuous hydrogen discharge directly in the reformer tube, the chemical equilibrium of the occurring reactions becomes displaced towards the products, resulting in more favourable process conditions and, consequently, in improved by 36% utilization of the feed hydrocarbons. At the same time, the hydrogen yield increases by 44%. The heat required, which is provided by a high temperature reactor, is 17% in excess of that in conventional plants. It can be expected that the simplified process design will produce substantial cost advantages over the existing processes for the production of hydrogen.

It should be emphasized that molecular hydrogen is an energy carrier but not a primary energy resource. Thus H2 must be produced using hydrogen and energy resources. By atomic hydrogen and energy sources, hydrogen can be produced from coal (gasification, carbonization), natural gas and propane gas (steam reforming, partial oxidation, autothermal reforming, plasma reforming), petroleum fractions (dehydrocyclization and aromatization, oxidative steam reforming, pyrolytic decomposition), biomass (gasification, steam reforming, biological conversion), and water (electrolysis, photocatalytic conversion, chemical and catalytic conversion). For fossil fuel-based H2 production in stationary plants such as coal gasification and natural gas reforming, it would be desirable to develop new approaches that produce hydrogen in a more economical and environmentally-friendly process that also

The core activities of the project were executed throughout the formation of National Teams of Bologna Experts who had the task and duty to contribute to the general and real awareness-rising on the topic of the higher education reform among different stakeholders in participating countries of the Bologna Process. The Croatian National Team of Bologna Expert (Hrvatska stručna skupina za Bolonjski proces was established in 2011. Among the diversity of activities executed by the student representatives in the Team, the important place is reserved for the deliberative workshops held during 2013. The target groups of the deliberative workshops were students and other stakeholders in the higher education. This paper presents the process of including the stakeholders in educational reform through the deliberative workshops. During the workshops, the organizers found out how the stakeholders are rethinking on some of the aspects of the Bologna Process, how they perceive and value the work of student representative and volunteering activities, and what they think about the extra-curricular activities of the student and how they value such activities. The form of deliberative workshops encouraged participants to freely and in constructive way express their thoughts and expectances in order to exchange ideas and knowledge about the matter, and to make a decision on common suggestions to solve a particular problem in the context of higher education (introduction of a new practice, modifications and alternations of existing practices, etc. This type of the application of deliberation method is extremely useful, which is the reason for the suggestion of the method’s use in preparing, implementing and evaluating the educational reforms.

This reform inter alia included a transfer of powers worth 20 billion euros from the federal level to the level of the federated states, a profound reform of the Senate, and a substantial increase in fiscal autonomy for the regions. This contribution critically analyses the current state of Belgian federalism. Although the sixth state reform realized important and long-awaited changes, further evolutions are to be expected. Since the Belgian state model has reached its limits with regard to complexity and creativity, politicians and academics should begin to reflect on the seventh state reform with the aim of increasing the transparency of the current Belgian institutional labyrinth.

    @@ The "Opinions on Deepening Power Institutional Reform in the 11th Five-Year Period" (referred to as "Opinions" below for short) finally unveiled and appeared clearly in the vision of the public on April 6th, 2007. Being the core of the power institutional reform, the "route map" of power tariff reform in the 11th Five-Year Plan period has also been clearly oriented. However, on the whole, the power tariff reform is no drastic as one imagines. With this doubt, the Journalist discussed this issue with Mr. Huang Shaozhong, deputy director of the Department of Price & Financial Supervision under the State Electricity Regulatory Commission, also a member of the Working Group of Power Institutional Reform.

    or process. The fact that upon independence in 1957 the Malaysian constitution accorded separate jurisdiction for the state and federal authorities on land and water issues has given rise to various points of contention when dealing with water policy reform, particularly the role, power and ownership of water resources between the state and the federal governments. In conclusion, the problems observed in Malaysia’s water services industry reform are mainly with regard to legislation. In-depth analysis of how the SPAN Act and WSIA impact available legislation and how these legislations can create an integrated water resource management system that works on both Federal and State levels are crucial. It is thus fundamental for legal regimes for water resources to support the legal regimes for water services. Only then, will the Federal government be able to take appropriate steps in restructuring the country’s water governance in its entirety.

    Russia is in the process of one of the most ambitious electricity reform programs ever undertaken. The reform is crucial for Russia, with the potential to modernize and transform the sector into a key driver of longer-term economic growth and prosperity. In 2005, the IEA published a study documenting the proposed reform and highlighting some potential implementation issues. Achievements to date have been impressive by international standards, however the outcome remains uncertain. Electricity reform is entering another critical phase in Russia. The 2013 Update examines the key remaining challenges affecting the development of competitive wholesale and retail electricity markets in Russia including: market structure, market design, pricing, investment and related regulation. The report draws extensively on the experience of IEA member countries and on views expressed during consultations with key Russian stakeholders.

    Full Text Available The rigidity of labour market has several important negative economic consequences: it stifles job creation, increases discrimination of those that it is actually aimed at protecting (young, women and the low-skilled, hurts the unemployed, slows down economic restructuring and damages its global competitiveness. But reforms are slow and often marked with disputes among partners in the collective bargaining process. Afraid of social security loss, unions usually oppose the reform, while governments usually give in to the union pressures and negative image of reform consequences created by unions and assisted by media. The characteristics of the labour market and labour market reform with respect to bargaining among power groups are examined both theoretically and empirically in the case of Slovenia.

    To meet the demands for high-octane gasoline and aromatics, catalytic reforming process has been advancing quickly in China. The reforming catalysts developed by RIPP have been used in more than 80% capacity of domestic CCR and SR units. This paper introduces the properties of PS-VI CCR catalyst developed by RIPP in recent years and also the result from commercial units. The PS-VI catalyst has high activity and good selectivity, under the same reaction conditions, the carbon on catalyst was lowered by 26% in mass as compared with that of the reference catalyst. Among the SR reforming catalysts, the new type of PRT series catalysts have excellent performance at low reaction pressure compared with the ref. Cat A. The aromatics and reformate mass yields of PRT catalyst were 2%~3% and 3%, respectively, higher than those of Cat A, and the run length was 30%~40% longer as well, which exhibits good prospect of application.

  11. Failure of health care reform in the USA.

    1996-01-01

    The failure of health reform in the USA reflects the individualism and lack of community responsibility of the American political culture, the power of interest groups, and the extraordinary process President Clinton followed in developing his highly elaborate plan. Despite considerable initial public support and a strong start, the reform effort was damaged by the cumbersome process, the complexity of the plan itself, and the unfamiliarity of key components such as alliances for pooled buying of health insurance. In addition, the alienation of important interest groups and the loss of presidential initiative in framing the public discussion as a result of international, domestic and personal issues contributed to the failure in developing public consensus. This paper considers an alternative strategy that would have built on the extension of the Medicare program as a way of exploring the possibilities and barriers to achieving health care reform. Such an approach would build on already familiar and popular pre-existing components. The massive losses in the most recent election and large budget cuts planned by the Republican majority makes it unlikely that gaps in insurance or comprehensiveness of coverage will be corrected in the foreseeable future.

    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 300-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 and published in April 1997. 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 successfully 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 (> 99.9999%) destruction of RCRA and TSCA hazardous halogenated organics, significant levels of volume reduction (> 400 to 1), and retention of radionuclides in the volume-reduced solids. Economic evaluations have shown the steam-reforming system to be very cost competitive with more conventional and other emerging technologies.

  13. The reformation of liquid hydrocarbons in an aqueous discharge reactor

    We present an aqueous discharge reactor for the reformation of liquid hydrocarbons. To increase a dielectric constant of a liquid medium, we added distilled water to iso-octane and n-dodecane. As expected, we found decreased discharge onset voltage and increased discharge power with increased water content. Results using optical emission spectroscopy identified OH radicals and O atoms as the predominant oxidative reactive species with the addition of water. Enriched CH radicals were also visualized, evidencing the existence of cascade carbon-carbon cleavage and dehydrogenation processes in the aqueous discharge. The gaseous product consisted primarily of hydrogen, carbon monoxide, and unsaturated hydrocarbons. The composition of the product was readily adjustable by varying the volume of water added, which demonstrated a significant difference in composition with respect to the tested liquid hydrocarbon. In this study, we found no presence of CO2 emissions or the contamination of the reactor by solid carbon deposition. These findings offer a new approach to the reforming processes of liquid hydrocarbons and provide a novel concept for the design of a practical and compact plasma reformer. © 2015 IOP Publishing Ltd.

    The article desired organizational and managerial changes in Primary Health Care, so as to develop a sound and feasible social marketing strategy. Key elements that should be changed are: 1. Rigid and centralized administrative structures and procedures. 2. Incentives system centralized and dissociated from the managerial structure. 3. Primary Health Care management units immersed in political conflict. 4. Absence of alternative in the margin. Users cannot choose. 5. Lack of an internal marketing strategy. Several ways of internal markets simulation are assessed as potential means for internal change. The need for an administration reform leading to a less inflexible system in the Spanish national and regional health services in reviewed too. Three changes are considered essential: a) Payment systems in Primary Health Care. b) Modifications in the personnel contracts. c) Reform of the budgeting processes. Specific strategies in each of these issues are suggested, making emphasizing the need of their interrelationship and coherence.

  15. Catalytic conversion of methane: Carbon dioxide reforming and oxidative coupling

    Natural gas conversion remains one of the essential technologies for current energy needs. This review focuses on the mechanistic aspects of the development of efficient and durable catalysts for two reactions, carbon dioxide reforming and the oxidative coupling of methane. These two reactions have tremendous technological significance for practical application in industry. An understanding of the fundamental aspects and reaction mechanisms of the catalytic reactions reviewed in this study would support the design of industrial catalysts. CO 2 reforming of methane utilizes CO 2, which is often stored in large quantities, to convert as a reactant. Strategies to eliminate carbon deposition, which is the major problem associated with this reaction, are discussed. The oxidative coupling of methane directly produces ethylene in one reactor through a slightly exothermic reaction, potentially minimizing the capital cost of the natural gas conversion process. The focus of discussion in this review will be on the attainable yield of C 2 products by rigorous kinetic analyses.

    Full Text Available In essence, the purpose of the implementation of agrarian reformis to improve the welfare of the poor peasants. Agrarian reformis not only understood as a policy for there distribution of land, but also as abroader process such as access to natural resources, financial/capital, technology, goods and labor markets, and also the distribution of political power. Equitable distribution of land tenureinrural areas as a result of agrarian reform will result in an increase in the welfare of the villagers who are generally small farmers or farm laborers. Agrarian reform plays an important role in the fight against ruralpoverty. The main target of the agrarian reformis the creation of social justice that is characterized by the presence of agrarian justice.

    In this work, an innovative method for gas conditioning in biomass gasification is analyzed. The objective is to remove tar by selectively reforming the unwanted hydrocarbons in the product gas with a chemical looping reformer (CLR), while minimizing the carbon formation during the process. Toluene....... Several variables affecting the reducing cycle were analyzed: temperature, time for the reduction step and H2O/C7H8 molar ratio. Ni40 and Mn40 presented interesting characteristics for CLR of biomass tar. Both showed stable reactivity to C7H8 after a few cycles. Ni40 showed a high tendency to carbon...... deposition compared to Mn40, specially at high temperatures. Carbon deposition could be controlled by decreasing the temperature and the time for the reduction step. The addition of water also reduced the amount of carbon deposited, which was completely avoided working with a H2O/C7H8 molar ratio of 26.4....

    . In essence, the agricultural reform programme represented market-oriented values that were not echoed in large parts of the Ugandan polity. The eventual reversal of policy, back to government-provided extension, and to a large programme of heavily subsidised input supply, testifies to that. In addition, key......This article explores the nature of ownership in a reform of the multi-donor-funded agricultural advisory service in Uganda. We argue that although there was a long process of programme formulation in which all stakeholders were heard, ownership was not as encompassing as it first appeared...... stakeholders, notably local politicians and officials in the Ministry of Agriculture, Animal Industry, and Fisheries (MAAIF), were shut out from the original programme and this threatened its viability. If a genuine analysis of the economic and political context had been carried out, the donors might have...

    Full Text Available Problems of accounting reform associated with the introduction of the practice of international accounting standards for accounting and reporting. Since 2013, introduced a new law "On Accounting". Many of the concepts and provisions were changed. This is true not only of the terms, but also the conceptual approaches to the organization and regulation of accounting businesses. In parallel with the work on the revision of this law for nearly fifteen years of work on the implementation of IFRS in Russian accounting practices. However, in recent years, this trend took shape in the form of the Russian Finance Ministry Plan for 2012-2015 for the development of accounting and reporting in the Russian Federation on the basis of IFRS. The article examines the areas of accounting reform that need to be taken into account already in the organization accountant accounting process across the enterprise.

  20. Private Investment in Power Sector in Developing Countries: Lessons from Reforms in Asian and Latin American Countries.

    2007-07-01

    The demand for investment in the electricity sector in the world between 2000 and 2030 is estimated to be USD9.8 trillion. Developing countries would require more than half of this investment. Given the limited fiscal space for public investment, a number of developing countries have undertaken policy initiatives to improve the investment climate for the private sector. The pace, scope, sequencing and outcome of reform process varies across countries. This paper undertakes a comparative evaluation of policy and regulatory reforms in Argentina, Brazil, India, Mexico, PRC and Thailand. The paper concludes that apart from macroeconomic stability, the pace and sequencing of reforms influences private investment in the power sector. Distribution reforms and setting up of an independent regulatory institution reduces risk for investors. A peace-meal approach to reform keeps uncertainties alive for investors and does not translate in significant investment in the sector. (auth)
