    Toxicity of petroleum component to aquatic organisms appears as a result of its deposition onto living organisms followed by its migration into bodies of the organisms, and emergence of toxicity from the migrated component. Effect evaluation processes standing on this viewpoint may include the exposure monitoring or migration monitoring, in which the petroleum component migrated into marine organisms is analyzed and the state of the component concentrated in these organisms is measured, or effect monitoring, in which actions of the petroleum component in the organisms are investigated. The effects of petroleum on aquatic organisms would include the following occurrence: direct fatal toxicity acting on cells and membranes, quasi-fatal toxicity causing death indirectly through feeding actions and abnormal actions, direct coating of oil on surface of organisms, which prevents movability and feeding actions of the organisms and reduces hydrophilicity of plumes and hairs, pollution of living organisms due to migration of carcinogenic aromatic compounds into bodies of the living organisms, and change in species compositions and geographic distribution of living organisms due to change in physico-chemical environment. This paper explains cases of detection and identification of organic sulfur compounds, aromatic compounds, polycyclic aromatic compounds, paraffins, olefins and heavy metals in parametric compounds of petroleum. 20 refs., 4 figs., 3 tabs.

    The Pacific region is a densely populated region where economy is developing at a high pace with China and other newly industrialized economies at the core. When energy balance in the region is studied, it is found that China and some others have already turned pure importers of energy and that probabilities are high that, along with development of economy and improvement on living standards, all the nations in the region will become pure importers. Accordingly, in the presence of urgent problems of global pollution and oil resources depletion, it is important to make sure that data particularly about the development of substitute energies for oil in this region be collected and duly dealt with for accurately predicting future developments. In this survey, a database is to be built to grasp the trends of energy supply and demand with attention focused on substitutes for oil which are available at hand. In this fiscal year, data for 1997 were added to the database for analysis into demand and supply of substitutes for oil in the Pacific region, and energy data were gathered for this purpose. Detailed tables of balance were compiled, broken down by energy source. Other detailed tables of balance were also prepared, these broken down by ultimate consumption department. (NEDO)

    The paper studied a scenario of the demand for power generation use methanol in Japan by grasping the situation of the utilization of methanol as fuel in the world, studying a scenario of power supply and the positioning of methanol power generation in Japan, doing a trial calculation of the breakeven price of power generation use methanol, etc. As to the usability of power generation use methanol as fuel, in the use for the reformed gas turbine and fuel cell, there is a possibility of making up for the disadvantage in fuel price by future technical development. For the fuel conversion at existing coal-fired power plants and the application of methanol to combined cycle and newly-installed boiler, it is necessary to have a substantial drop in methanol price. Taking an advantage that methanol can be transported in small size and easily be stored, methanol can possibly be used as fuel for dispersed power sources. The potential demand for petroleum substituting methanol is estimated at approximately 25 million t/y, assuming it to be 1/2 of the petroleum consumption amount. The present methanol market in the world is not so large for quantity use as fuel, and for the introduction, therefore, it is necessary to secure flexibility in supply. (NEDO)

    To promote the introduction of methanol fuel into the thermal power plants, total assessment was provided. For calculating the methanol production cost, the plant was assumed to be constructed in the Southeast Asia or Middle East. Two methods, i.e., steam reforming and gaseous phase fluid methods, were investigated. Since the price of natural gas is low in the Middle East, the methanol production cost by the gaseous phase fluid method is estimated to be about 1.5 yen per thousand kcal. The transportation cost can be reduced into one-half to one-third of current cost using a large-scale tanker. Although the heating value of methanol per weight is lower than that of LNG, the volume flow of methanol is similar to that of LNG due to its low specific gravity. Conceptual designs were conducted for some power generation systems, such as gas turbine of combined cycle, diesel engine, and fuel cell. The power generation cost was estimated to be 8 to 9 yen per kWh, which depends on the receiving price of methanol. It is nearly equivalent to that of LNG combined cycle power generation. There are no problems of air pollution and ash disposal. When considering the long-term security of energy sources, the use of methanol would be one of the selections as utilization of natural gas. 6 refs., 33 figs., 25 tabs.

    For the purpose of reducing the CO2 emitted from electricity/vapor supply facilities of Bataan Refinery in the Philippines, study was conducted of optimum energy supply facilities considering the effective use of the oil residue and future reinforcement of the refinery. Concerning the high-pressure/high-temperature condensing extraction boiler/turbine cogeneration, gas turbine cogeneration and low speed diesel engine cogeneration, comparative study was carried out in terms of thermal efficiency, reliability/preservation, environmental acceptability, effectiveness of measures for the future excessive oil residue, etc. As a result, the study was concluded as follows: the electric power consumption will markedly increase in the future; however, in the light of the situation of the refinery where the vapor demand will not increase, it is the most suitable to use low speed diesel engine cogeneration facilities as on-site power generation facilities which can burn the excessively increasing oil residue as direct fuel. The CO2 reduction effect estimated from the project on the present scale was 132,880 t-CO2/y, and the energy conservation effect estimated was 50,861 toe/y. (NEDO)

    For the purpose of using methanol as power generation use fuel, the paper carried out of the conceptual design of methanol reformed high efficiency gas turbine and the evaluation study of economical efficiency. The methanol reformed gas turbine is to recover the heat from turbine flue gas and to improve thermal efficiency by using the fact that the vapor reforming reaction or decomposition reaction of methanol advance endothermicly at low temperature between 250 and 350 degrees C. It was judged that the combination with the existing technology made the practical application possible and that it was appropriate to adopt the regenerative gas turbine/water-injection and reforming (RGGT/WI and R). As a result of the trial calculation of construction cost of RGGT/WI and R and calculation of power generation cost, RGGT/WI and R became more profitable than the simple open gas turbine at a capacity ratio of 10% or more, and became more profitable than the combined cycle at all capacity ratios. In the use of RGGT/WI and R, which uses methanol as fuel, SOx is not included in flue gas, and the NOx included is estimated at 35ppm or so. The amount satisfies the standard according to the boiler using fluid as fuel. (NEDO)

    This paper describes the result of a toxicity test by means of a shaking culture on municipal sewage effluents using seaweed as a test living organism. Dead cells of porphyra yezoensis (nori) have emerged more specifically with the addition of non-disinfected secondary treated water at about 1% and with the lower the salt content. This phenomenon is thought to be an antagonism among growth accelerating substances for porphyra thallus, growth inhibiting substances, and salt content, one of the important characteristics of non-disinfected treated water. As a result of culture test on ripe seawater added with chlorine-disinfected secondary treated water, it was found that the growth of porphyra yezoensis (nori) is governed completely by concentrations of free chlorine added to the treated water, but very little by the treated water addition factor. Substances with very strong growth inhibition power, including NH4Cl, are generated in the chlorine-disinfected secondary treated water. It was disclosed that growth ratios of giant kelps at different factors of addition of non-disinfected secondary treated water change with the sampling time; water quality of the treated sewage water changes from one hour to another; and there are two time bands that show the growth ratio of about the same extent and a time band that shows a transition growth ratio. 60 refs., 8 figs., 2 tabs.

    A table, chronology of petroleum geophysics in overseas and in Japan, has been prepared for the convenience of checking events, which are thought to be important as notable affairs in application, success, and technical innovation. In overseas, successes in the 1920s were remarkable, when the US modern geophysical exploration made a start. Successes in determining the position of exploratory drilling by means of the gravity torsion balance, fan shooting seismic refraction method, and seismic reflection method occurred one after another. The USA has kept its situation stably as the number one by the seismic reflection method occurred most lately, and its life has been further elongated by adopting digital techniques. The CDP technique which became to be used simultaneously, and the seismic sources without using explosives, such as vibro-seismic source and air gun, extended the success of digital techniques drastically. In the future, the progress of 3-D exploration technology is expected. In Japan, about 18 years lag in the seismic reflection method is observed when compared with the USA. Japan has provided leading techniques in the shallow layer seismic reflection method and S-wave exploration. 40 refs., 1 tab.

    The activated sludge process and other biological treatments, though utilized for most sewerage and drainage water disposals, often necessitate the maintenance to be managed with a professional knowledge so that confrontation is oftem impossible with trouble in management. In the present report, different basic studies are to be introduced of microbial activation by an addition with saponin. Saponin'', etymologically identical with savon'' and soap'', has been being used as natural cleaner, emulsifier and foamer in South America and Europe since olden times, and is used also for the processed food and potable water in the USA. The present experiment concluded that, in case of using it as microbial activator, the activated sludge can be considerably increased in load quantity of disposal by the heightening in oxygen-supplying power, high concentration microbial maintenance, microbial activation, etc. In the future, there will remain many problems unsolved such as what is the optimized condition for the addition depending upon the condition of base material. 3 refs., 6 figs., 1 tab.

    At first, flagellar motors of bacteria are reviewed as a typical example of molecular machines in living cells. A rotational motor is embedded in the cell membrane at the root of the flagellum. The driving power of the rotation is the flow of hydrogen ion from the inside to the outside of the cell. In a normal state of a bacterium, potential difference of about 0.2 V is produced by the ion pump existing in the cell membrane. A molecular motor of sliding motion of muscle attracts the attention on the relation of the input and output of the molecular motor. The mechanism of the smooth motion without fluctuation in the fluctuated environment and the fluctuated input is unknown. Next, the motion of Paramecium is discussed as an example of a system composed of a number of molecular machines. Paramecium moves to a place of a suitable temperature when placed in a water tank with temperature gradient, however, it does not stop the motion at the place of the suitable temperature and increases a probability to change the direction when leaving, that is it takes a method of indirect probabilistic control. 12 refs., 8 figs.

    This paper describes the following matters as one example of structural coloring of non-motional nature on the coloring mechanism in wings of Morpho sulkouskyi butterfly: The structure of scales on butterfly wings may be modelled into such a structure of a right angle frame of reference having a cyclic arrangement (with an interval of 0.7 [mu]m) of a zigzagged protrusion in the 'x' direction called a ridge (with a height of 1.8 [mu]m and a width of 0.54 [mu]m, the shape not changing in the 'y' direction), and having a plurality of protrusions of a ridge form called lamella in the 'z' (height) direction. A simple multi-layered thin film model was assumed that has lamella layers and air layers laminated alternately in the 'z' direction. The model was used to calculate reflection spectra on vertically incident light based on thickness and refractive index of material layers determined by a structural analysis of the scales. The result was considerably close to the reflection spectra of scales measured by using a microscopic spectrophotometer when the number of layers is set to six. The paper describes briefly examples of motility structural coloring (skin cells of rainbow color in tropical fish). 7 refs., 12 figs.

    Some recent information is presented about the adhesion of organisms to marine structures. A biocoating is a community of microorganisms adhering to the surface of an object, composed of a matrix of exocrines and what it carries, which are suspended matters originating in the seawater and organic particles originating in the organisms. As a biotechnological measure for preventing the adhesion of large organisms, there is the use of synthetic repellents. New chemicals, however, have to clear the law requesting a review and approval of the authorities concerned before they can be put to use. Furthermore, their cost if high will give rise to another difficult problem. There are two chemical methods against them, one the injection of chemicals aiming at all larvae on the adherence stage and the other the execution of electrolysis for the formation of repellent chemicals in the seawater. In case a thick chemical concentration is mandatory for a good result, chemicals may be allowed to melt out of the coating or surface electrolysis may be caused by use of a conductive coating. Available for providing the object with an organism-rejecting surface are functional materials such as silicone, chlorine generating electrodes, and repellent-containing carriers. Also mentioned in this report are electrochemical methods, use of copper alloys or zinc, and application of silicone-based coatings. 129 refs., 16 figs, 8 tabs.

    Bulks of photosynthetic product to reduce the carbon dioxide by the light energy are forests, represented by the tropical rain forests, on the land, and marine algae and coral reefs in the ocean. For the purpose of effectively utilizing the fixation power of carbon dioxide through the photosynthesis by higher plants and algae, it is necessary to make many further researches, starting with a conditional selection of species, excellent in both absorption and fixation of carbon dioxide. The Japan Technology Transfer Association has recently issued a design to build a large scale closed type farm in the vicinity of factory, exhausting the carbon dioxide, and supply it to structure a system of producing vegetable and other food. What largely contributes to the calcification in the ocean is the coral reefs, where coral is symbiotic with brown algae., called dinoflagellatae. Those algae are judged to accelerate the formation of calcium carbonate by the photosynthesis. To estimate the absorption power of oceanic carbon dioxide, it is important to quantitatively know the calcification by the coral. 4 figs., 1 tab.

    Researches into organisms for their information processing, conducted in fiscal 1988 as part of a 'biological device research and development' project under the research and development system for basic technologies for the next-generation industry, are compiled into an article entitled 'information processing in neurons, and calcium ions.' The level of neuronal activity depends on changes in the level of nerve-membrane ion channel activity. Some kinds of ion channels are chemically activated (or inactivated) within the membrane. The phosphorylation of a protein ion channel is a typical case where an ion channel level is regulated chemically. In the muscarinic response of a neuron, a chemically operated ion channel plays an important roll relative to neuronal functions. In this response, a second messenger system in the neuron transmits extracellular information to the chemically operated ion channel. In this system, a calcium ion is one of important second messengers. (NEDO)

    The French Government most enthusiastically promotes development of bio-gasoline in renewable energy field. EU makes pressure to remove the French Government`s fiscal advantages for bio-gasoline which only benefit French farmers, and the IEA (International Energy Agency) report also estimates no benefit corresponding to the fiscal support cost. Start of the `Eolien 2005` project is attractive in renewable energy field which aims at construction of wind power generation stations of 250-500MW by 2005. The `Eolien 2005` project is mainly supported by Electricite de France (EDF) who guarantees the purchase of produced electric power at a submitted price. In addition to this subsidy activity, EDF decided to positively tackle renewable energy. On R and D efforts for renewable energy, France belongs to the most poor countries among IEA countries, and in addition, the effort is considerably concentrated onto the study on reduction of production cost for bio-gasoline. There were no changes in this situation in 1996. 7 refs., 5 figs., 31 tabs.

    For analytical evaluation of effects of environmental protection measures, energy conservation measures, new energy promotion measures, etc., a very-long term energy supply/demand model was developed and used for a simulational study. The model is composed of the models of macro economics, secondary energy prices, new energy introduction, and energy supply/demand. The feature is that the amount of new energy introduction is measuringly analyzed based on the cost and market scale, and integratedly estimated in a frame of energy supply/demand of the whole Japan. As a result of the simulation, energy source as of 2030 is composed of coal (17%), oil (44%) and nuclear power (15%) in the case of the economic growth as viewed optimistically. Contrarily, in the case of it as viewed pesimistically, energy source is composed of coal (11%), oil (40%) and nuclear power (22%). CO2 emission is -12.4% in the case of the new energy promotion than in the standard case. 7 refs., 79 figs., 107 tabs.

    For the econometric analysis of petroleum substitution energy, a domestic econometric model was developed which can concretely and econometrically grasp and analyze effects of measures taken for environmental policies, energy conservation, promotion of new energy, etc. The model was made so synthetic as to catch a relationship between energy supply/demand and changes of econosocial structures in economic growth, industrial structure, life style, etc. which are extremely important elements for catching future energy demand. The model is composed of a secondary energy price model, a new energy introduction model, and an energy supply/demand model. As case parameters, selected were the price of crude oil, introduction of new energy, GDP and energy conservation, and the following cases were assumed: standard case, high price energy case, new energy introduction promotion case, low economic growth case, energy conservation case, and low energy demand case. The results of simulating each of these cases were indicated. 91 figs., 110 tabs.

    A survey was conducted of bio-chemical complex harmonized with the global environment for the purpose of constructing the material production process harmonized with the environment by the process fusion between biological conversion and chemical reaction. Palm oil was taken up as renewable raw material plant resource. The process utilizing bio-chemical reaction advances at normal temperature and pressure and is high in reaction specificity and selectivity. This is a recycling, circulation and environmental harmony type production technology which brings high yield, energy conservation, resource conservation, and low environmental loads. Waste water treatment and production of useful substances from sludge were thought as elementary technology. A possibility was studied of enzyme production by culturing solid waste, and the enzyme was applied to the hydrolysis process. The paper indicated trace components in the palm oil and the extraction method and proposed the production process of new derivatives for adding value to hydrolysate. A study was also made of the overall process flow which integrated these new processes and the material balance. The comprehensive evaluation of this new process was made from the aspect of the product structure, the market, construction cost, economical efficiency, and the environment. 133 refs., 65 figs., 56 tabs.

    The relationship between environmental control and biotechnology is discussed, and purification of moats and lakes is taken up as a concrete example of introducing biological waste water treatment technology to ecotechnology. In addition, an overall waste disposal system connecting cities and agricultural districts is investigated. After the purification of water and waste problem solution, etc. are discussed, the importance of creating ecopolis and ecotown is described. The 3 concepts of microbial ecotechnology (high densification of organism, field control, interaction between organisms) are used to explain biological treatment technology. Attempts for direct purification and ecotechnology are described quoting a few examples. If waste produced in cities and ligneous materials or charcoal obtained from forests are mixed for treatment, effective waste treatment or new resources production may be possible. It seems to be possible to create ideal ecopolis and ecotown by applying the doctrine of irrigation, drainage and reclamation engineering and the technology established by now. 35 refs., 1 fig., 2 tabs.

    The new biological deodorization device was developed using dried activated sludge as deodorant. Activated sludge obtained from a waste water treatment plant was dried at room temperature to protect from extinction of microorganisms in it before its charge into the device, and washed by water only as required. Offensive odor substances were oxidation-decomposed by microorganism after their adsorption into sludge surfaces, while microorganisms survived for a long time while getting such substances as nutritive sources. As basic deodorization characteristics were studied with the experimental device and artificial odor gases, more than 99% of 200 and 2,000 ppm H2S were removed at space velocities of 400/h and 33/h, respectively, together with nine typical offensive odor substances. As the result of demonstration tests with the small test device installed in a public waste water treatment plant, a high deodorizing efficiency was retained for 10 months or more, and its running cost was as low as 75% of that of current systems because of only one necessary washing every month. 3 refs., 14 figs., 12 tabs.

    Petroleum production and its supply and demand require ever closer coordinations among the countries involved. On the other hand, however, there a large number of difficult questions as the problems of global environmental pollution and greenhouse effects increase their seriousness and the economic resources in the petroleum business become scarcer. This paper describes the current state of the Japanese petroleum development, the necessity of spontaneous petroleum development, the international trends in the petroleum development business, and the tasks for Japan in the petroleum development business. Japan is a late comer in the petroleum development business. There are such difficulties as sizes of oil fields being discoverd are becoming smaller, the natural conditions in development target areas are getting severer, and the economic effects are inferior. Japan, whose petroleum self-supply rate is about 0.3%, whose petroleum dependency is heightening as a result of increase in nuclear power generation, and who is the third largest petroleum consuming country next to the U.S.A and Soviet, must use efficiently her financial and technical powers to vitalize her spontaneous petroleum development. Japan has a duty to contribute to the world {prime}s future stabilized supply of oil. The Japanese Government has launched the five-year fund development plan to perform basic surveys for ail in the north-east part of the Japan Sea and the pacific Ocean.

    This paper discusses how to promote international lateral work sharing and how to strengthen infrastructures in the petroleum industry, as a problem prevailing over the petroleum refining facilities in Japan. Excess distillation facilities have been applied with the disposition policy. However, in view of the supply and demand situation in petroleum products for medium to long term span in the world with the pan-Pacific region as the main concern, that applicable to Japan, and that experienced during the Persian Gulf crisis, the excess facility disposition policy was revised, particularly on white kerosene, of which supply and demand tightness is concerned about, so that production capacities may be increased as required. Japan, a large presence in the international economics, is required to work more positively on petroleum refining facilities located in the oil producing countries and intermediate locations to promote the international lateral work sharing. On the one hand, in order to strengthen the infrastructures in the Japanese petroleum industry, it is necessary to promote rationalization and use at higher efficiency of the oil supply system, and convergence of the the petroleum industry, including joint investments for projects exceeding capabilities of individual enterprises. 3 tabs.

    This paper summarizes the former half part of the analysis made on business strategies of major international oil companies. The net earning of R/D Shell in fiscal 1994 increased by 1.8 billion dollars to 6.3 billion dollars. Its loan rate decreased to 16.7%. It increased the crude oil production by 3% to 2.2 million B/D, and the natural gas production by 1.2% to 7.3 billion cfd. The upstream department had the net earning decreased by 23% to 2.4 billion dollars because of decline in crude oil price. The net earning of the downstream department showed an increase by 20% over that in the previous year to 3.2 billion dollars. The chemical department had its business turned to black ink. The net earning of Exxon in the same year decreased by 200 million dollars to 5.1 billion dollars due to the reduced crude oil price and low refining margin. The upstream and downstream departments showed a decrease of 530 million and 630 million dollars respectively. The chemical department had an increase of 130% to 950 million dollars as a result of the recovery in the European markets. The net earning of Mobile in the same year showed a decrease of 2.1 billion dollars, ending in the amount of 1.1 billion dollars. The decrease has been caused by the decline in crude oil and natural gas prices and a 30% reduction in the refining margin. The chemical department changed for the better, with improved sales margins in oil products sold in overseas markets. 28 figs.

    In East European countries (Albania, Bulgaria, Czech, Slovakia, Hungary, Poland, Rumania and former Yugoslavia), energy prices were raised as part of the general price reform in the initial stage of the economic reform. Trade regulations on energy products were relaxed, and prices of tradable energy products were made free. Even in countries such as Rumania and Bulgaria where there still remain controls, the governments aim at perfect liberalization. Thus, this paper first considered the energy situation of East European countries where economy and society are now changing. Described were the overall economy situation and energy supply/demand in East European countries. Next, the paper detailed the energy situation in Hungary and Poland. In conclusion, the paper considered energy and international cooperation, and Pan-european Energy Charter which are important future issues in the energy sector of East European countries. 10 refs., 36 figs., 26 tabs.

    The paper investigates and reports the trend of the development of petroleum substitution energy in the U.S. The Clean Coal Technology Plan is one of the plans which were implemented most successfully in the past several years. The plan made a remarkable reduction in NOx and SOx emissions possible. As for natural gas, importance is placed on improvement of production/storage technology of natural gas and high-effective low-NOx-emission turbines. As to the research on nuclear reactors, importance is now placed on the light water reactor plan, and the target is the design and development of such nuclear reactors as electric power companies pay attention to. The solar cell industry is markedly developing, and the shipment grows 17% per year. However, the price is rapidly declining. The wind turbine and biomass power generation plans are also advanced, and most of the plans are aimed at the development of new fields of application. With regard to geothermal energy, slowness is seen. Concerning electric vehicles, no makers enter into the quantity production, but the research and development are actively being made. 72 refs., 26 figs., 51 tabs.

    The paper investigates and reports the developmental trend of petroleum substitution energy in Germany. Policies for the technical development and actual introduction of petroleum substitution energy in Germany are concerned with three energies: coal, natural gas, and new energy, except nuclear energy the use of which is against public opinion. Coal is the only abundant domestic resource, but not internationally competitive because of its cost. Brown coal obtained from the open pit mining is an abundant and low-cost domestic resource, but has the environmental problem. The latest technology is actually being introduced in which the thermal power generation is integrated into gasification, and the gas/steam turbine power generation. Natural gas is advancing in the use as energy source for space heating substituting for brown coal. The technology development of new energy is promoted mainly on such wind power and solar energy as are called renewable energy. As to the development of technology using renewable energy for which the rapid increasing use is not expected in near future, the target is directed mostly to CO2 control and the third world where there are no public electric power nets. 30 refs., 10 figs., 8 tabs.

    Fluid flow tomography (FFT) was applied to monitor the behavior of underground fluid in steam enhanced oil recovery (EOR) for oil sand reservoirs. FFT uses electrode arrangement of a mise-a-la-masse method, and continuously measures time variation in charged and spontaneous potential at various surface points to obtain realtime the images of underground seepage flow. It continuously measures ground surface potentials of 120 channels at intervals of 2s by applying alternative DC between a casing pipe and distant current electrode. It separates charged and spontaneous potential components, and converts them into time series data. It estimates the time and spacial distributions of seepage flow from time variation in spontaneous potential. It determines the change rate distribution of time-sliced apparent resistivity from charged potential to estimate the scale and area of seepage flow. As the experimental result, positive and negative electrodes in the change rate distribution were observed, and the direction connecting each electrode agreed with that of resistivity anomaly. FFT could observe realtime time variation in apparent resistivity due to steam injection. 9 refs., 7 figs.

    This report summarizes the fiscal 1999 research result on simulation analysis on petroleum substituting energy. The simulation model for analyzing social and energy supply and demand structures comprehensively was established by improving the China and Korea models developed in fiscal 1998 through a use of input-output tables. In simulation of the China model, the reference case showed that a primary energy demand in 2030 reaches 3.3 times as much as that in 1997 (2.9 times in CO{sub 2}), resulting in serious energy and environment problems. Reduction of primary energy and CO{sub 2} is possible by promotion of energy saving and introduction of a carbon tax. In simulation of the Korea model, the reference case showed that CO{sub 2} emission in 2030 reaches 2.2 times as much as that in 1997, showing an annual increase rate of 2.4%. The annual increase rate can be reduced by introducing a carbon tax. The simulation model for automobile energy was also established for major countries in Asia. Automobile energy consumption increases with diffusion of automobiles until 2030 gradually. In particular, the consumption in China reaches that in Japan in 2010. (NEDO)

    The paper investigates and reports policies for and the developmental trend of petroleum substitution energy in the E.U. The technology of 18 wind turbine makers in West Europe is on a level that they can almost sell MW-class turbines for practical use. The wind turbine industry in Denmark is on a level of No.1 of the world, and occupies approximately 50% of the world market share. The capacity of the wind power generation in Germany which finished the installation at the end of 1995 exceeded 1000 MW. EEWC has recently been established as an organization for using waste as energy. Municipal solid wastes discharged in West Europe are regarded to be equivalent to 5% of all the power demand there. In Spain, biomass is a petroleum substitution energy source which is most used. A target amount for the use set by the government is equal to 427000 tons in oil. Biomass is most used in the residential field, and it is mainly the use of agricultural and forestry wastes as fuel. Rapeseed oil is studied as fuel for bio car. In Denmark, production of rapeseed as fuel use crop is increasing. 14 refs.

    Such nutrients as nitrogen and phosphorus discharged into lakes and rivers can cause organic contamination as a result of eutrophication in water areas if they are left as they are. However, they can be re-utilized as resources if they are utilized more effectively. This paper reports a hydroponic organism filtering method as a promising method of utilization thereof. It also explains transition in organism phase in rhizosphere and a water purification experiment. Such suspended matters as phytoplanktons in raw water are filtered and captured by roots of plants; such small animals as tendipedidae and physia live symbiotically in the rhizosphere; their excrements and nutrients are absorbed into and utilized by plants; and coexistence is made possible between diverse water-front environments including terrestrial systems and diverse living organisms. Cresson cultivation, observation on transition in the benthos composition, and a lake water purification experiment were carried out at the Kasumigaura Lake experimental facility. Various findings were acquired such that, in order to attain diverse coexistences including those with natural enemies and well-ventilated environments, a water channel of larger than a certain size is required. Results were also obtained that can be expected as an effective technique that may be used in public water areas. 3 refs., 4 figs.

    This paper describes a pilot plant study on algae removal of a fluidized bed biofilm reactor system for lake water treatment. The system does not need backwashing because the fluidized bed suffers no clogging. Moreover, the system uses dissolved oxygen in influent water for aerobic biological treatment without aeration equipment. Thus, this system is a low energy and easy maintenance way to purify eutrophic lake water. The system was operated continuously at a flow rate of 1500 m{sup 3}/d{sup 1} for 9 months at Tsuchiura Port in Lake Kasumigaura. In this study, chlorophyll-a and dissolved oxygen in both influent and effluent water were monitored continuously. In summer (August to September) when water bloom occurred, the average removal efficiency of chlorophyll-a was 64% at the average influent chlorophyll-a concentration of 137.8 {mu}g/l{sup 1}. During the total experimental period (9 months), the average daily amount of removed chlorophyll-a was 40.3 g/d{sup 1} at the average influent chlorophyll-a concentration of 89.5 {mu}g/l{sup 1}. By analyzing the relationship between the removed chlorophyll-a and the consumption of dissolved oxygen, it was estimated that almost all of algae trapped in the reactor was degraded biologically. 20 refs., 12 figs., 2 tabs.

    With an objective to utilize sewage sludge more effectively, composted sewage sludge has been applied to seed beds to investigate its effect on soil macrofauna and higher fungi, and its relativity with change in soil organisms, growth of young trees, and soil science. Forty-eight seedling sections, each 5 m [times] 5 m, were made on a seed bed which was applied with Tenryu sludge composts (polymer-based coagulant), several other kinds of sludge composts, fallen leaf composts, and cattle excrement composts at predetermined rates from zero to 20 kg. Each section was planted with 25 three-year-old nursery trees of a kind of oak, black pine, and cypress. As a result, the following findings were obtained: wet weight of larvae of Japanese gold beetles that attack tree roots has increased during the first and second years in the Tenryu sludge applied section, but no longer increased in the third year; the relationship between the other composts and soil macrofauna was not made clear; Scleroderma Cepa PERS, a mycorrhiza bacteria, has been generated in the oak planted section in the second, third and fourth years, with the second year particularly having generated it in a greater amount in proportion with the fertilizer application amount, but the fertilizer effect thereafter is not clear. 24 refs., 6 figs., 9 tabs.

    For the purpose of smoothly introducing biogas plants to Hokkaido in the future, the following were conducted: collection of the data on samples of development/introduction of biogas plants, survey of the organizations concerned, etc., study of economical efficiency, etc. Those were arranged as a guide for biogas energy utilization in Hokkaido. In the biogas plant, organic matters such as animal faces, garbage, etc. are anaerobicly fermented at medium temperatures between 35 and 38 degrees C or at about 55 degrees C to obtain biogas including methane gas of approximately 60%. From this gas, heat is obtained by gas boiler, and also electricity and heat are obtained by gas cogeneration or fuel cells. In the case of introducing the biogas plant using animal faces as raw material in Hokkaido, it is important to cover all the electricity and heat used to maintain the plant with the biogas obtained, from a viewpoint of economical efficiency. In the present situation, it is the most economical for each farmer to introduce an individual plant to be installed and to obtain the power generated and heat. (NEDO)

    As carbon dioxide-related environmental measures, method was explained to chemically convert and utilize carbon dioxide. Synthesis is possible of methanol, carbon monoxide, different carbohydrates, etc. by catalytic hydrogenation of carbon dioxide, using hydrogen produced by the electrolysis of water. Task consists of heightening in both convertibility and selectivity, and abundant supply of low cost hydrogen. Methane, alcohol, etc. can be synthesized by electrochemical reducion of carbon dioxide. Because of effectively inserting multiple electron, discssion is being made of catalyst, intergrated with electrode, and electron transmitter. The photoelectrochemical reduction of carbon dioxide can be also made by utilizing photoelectric current, generated upon photoradiation on the semiconductive electrode. However, task consists of heightening in both efficiency and selectivity. Photochemical reduction of carbon dioxide, actually made by green plant, consists of oxidationlike decomposition of water and reduction of carbon dioxide. Both those reactions are skillfully separated by intermediation of very quick electron transmission system. Reduction is being studied with semiconductor, metallic colloid, enzyme, metallic complex and other various catalysts. 10 refs., 3 figs., 4 tabs.

    For the establishment of the basis of supercritical fluid technology, we perform elucidation of the specific feature of the supercritical fluid as a reaction media and development of some new process. In this study, we first studied the fluid structure of SCF through in-situ spectroscopy and MD simulation. As a result, significant hydrogen bonding amongst water molecules and a solvation structure around the solute were observed in the supercritical state. This fluid structure has new features different from that of high temperature steam or liquid water. We found that this is closely related to the difference of bulk properties of SCF and local one around the solute. On the basis of these fundamental findings and with the better understanding of the specific features of SCF as a reaction media, development of some new process had been conducted more efficiently and successfully. The processes being developed in this study include 1) waste biomass and plastic conversion to recover chemicals, 2) hydrogenation of heavy oil for desulphurization through partial oxidation 1 and 3) hydrothermal synthesis of metal oxide fine particles.

    Cellulose produced by bacterial is called bacterial cellulose (BC). The morphology and physical properties of BC are found to be quite unique in comparison with those of higher class plants. The properties are elucidated and a study is made to utilize the properties. The outline of this study is introduced in the sequence of BC production, BC morphology, elucidation of the physical property, and study on the application. BC consists of ultrafine fibers, and the widths of fibers are in the range from (1/199) to (1/1,000) of cotton fibers, forming distinctive network structure. It is assumed that the high Young`s modulus is based on the structural features of BC. Researches have been made on various applications to such fields as audio, paper, food, and compounds where the features of cellulose are utilized effectively. The morphology of cellulose can be varied by adding drugs which can change a part of the protein. It is expected that cellulose structure can be controlled in the future by the application of this technology. 18 refs., 6 figs., 2 tabs.

    This paper introduces the polymer dispersed liquid crystal (PDLC) ACT'' sheet, a liquid quartz light modulating film, developed by the Ajinomoto Company in Japan. A mixture of liquid crystal and polymer precursor is sandwiched between polyethylene terephthalate films imparted with transparency conductor made of indium tin oxide (ITO), which is then polymerized by heating or irradiating ultraviolet rays to obtain a PDLC. The film has a thickness as thin as about 0.3 mm, and good processibility. The sheet uses light modulating elements functioning on scatter and permeation of light. Clarification was made on the voltage dependence of cloudiness, total light permeability, straight and parallel light permeability, the response, and the operating voltage. The system consumes small amount of power with a threshold value of about 35V, and is suitable to operate large areas when working on the utility power supply. An incident light having a high diffusion capability when the electric field is turned off exhibits a high clouding function. The system gives an excellent feel of colorlessness and transparency when the electric field is turned on. The performances in heat insulation, infrared reflection capability and noise resistance are expected to be compounded for a functional versatility. 4 refs., 6 figs., 2 tabs.

    In order to develop a seawater desalination equipment utilizing solar heat, a performance test was performed on a three-stage solar heat vacuum distiller. The equipment can evaporate and condense water at low temperatures by reducing the pressure in a distilling section. Solar heat is collected by a heat collecting plate, by which water as the working fluid is evaporated and moved to a heat conducting section in an evaporation pipe in a state of steam. The steam is condensed in a low-temperature heat conducting pipe, the heat is released outside the heat conducting pipe, and seawater is evaporated under low pressure condition. The working fluid is circulated for repetitive use. Solar cells are used as a motive power source for a vacuum pump, hence the system is self-sustainable even if installed in a desert area and the like places. The construction is simple, highly durable, and easy in maintenance. The system has high water producing performance, uses no harmful substances whatsoever such as fluorocarbons, and is a friendly system to the global environment. Because of evaporation at low temperatures, heat loss to the surroundings and sensible heat due to temperature rise are small, and the system response is quick. The solar heat can be utilized more effectively as multiple effects. When a heat collecting plate of 7.76 m {sup 2} was used, maximum yield of 105.45 kg/day was obtained. The system`s distillation efficiency is higher than other types of solar heat utilizing distillers. 7 refs., 5 figs.

    This paper describes the measurement and analysis for clarifying solution structure of supercritical water and exhibition mechanism of solvent functions. It also describes the development of new processes using supercritical water as reaction solvent. The PVT measurements were conducted in the supercritical region using pure water and NaCl aqueous solution, to confirm the reduction of molar volume of the electrolyte solution. The hydration structure was examined in the supercritical aqueous solution by the molecular dynamic simulation. As a result, presence of hydrogen bond structure, where the contribution of two branching hydrogen bond can not be ignored, was suggested under the supercritical condition. Characteristics of supercritical aqueous solutions are analyzed through in-situ Raman and scattered X-ray spectral measurements. Moreover, this paper introduces developments of some processes in the supercritical water, such as decomposition of wasted polymers, recovery of chemical materials, reforming of heavy hydrocarbons by contact hydrogenation, and synthesis of fine powders of metal oxide by reaction crystallization.

    The aim is to improve on hydrocarbon oxidation which is a difficult reaction (analogous to combustion and having potential for heat generation or explosion, with restrictions therefore imposed on reaction conditions) by use of a catalyst supporting porous membrane. The fiscal 1999-2000 results are stated. In this effort, the target reaction is promoted by a catalyst supported by a porous membrane while combustion is controlled by the said porous membrane that separates oxygen and hydrocarbon from each other. Such a design was not available since a catalyst supporting inorganic membrane withstanding so high a temperature was difficult to prepare. Recently, however, a porous membrane with its pores regulated to microstructural dimensions was developed. The activity of a Pd membrane catalyst is evaluated in view of the degree of oxidation of propylene, cyclohexene, and benzene. It is then found that hydrogen that has passed the Pd membrane participates in the reaction. In a propylene oxidation test using a membrane type Ag/Al{sub 2}O{sub 3} catalyst, it is found that acetone is generated and that oxygen after passing through the membrane participates in the reaction. Methods are studied for preparing a metal membrane in which the catalyst system comprises a catalyst supporting porous membrane and a Pd membrane. In the fabrication of metal membranes, a highly selective hydrogen permeable membrane is stably prepared by the thermal CVD (chemical vapor deposition) method. (NEDO)

    The EU is one of the most advanced places of petroleum substituting energy development. The EU is highly aware of environmental issues. For the COP3 held at Kyoto in December 1997, The EU gave more severe regulation of CO2 emission than the other advanced countries. The EU takes efforts in the development and introduction of energy effective for global environmental protection. In addition, research and development of geothermal, biomass and wave force energy are actively promoted in this place. Energy situations in this place are significant for predicting and analyzing the future trends of energy development and consumption in the other countries. Firstly, this report looks back toward energy demand held in check to a head at the beginning of the 1990`s.

    This paper reports the achievements in fiscal 2000 in development of a technology to evaluate reliability of petroleum refining facilities. The development efforts were made mainly on analyses by simulation and neural net (NN) that utilize computers. In the high-temperature system facilities, the creep damage generation is governed by different factors including impurities. The evaluation on joint life requires simultaneous use of low temperature zone long-time test. Verification was made on application of non-destructive inspection, such as use of ultrasonic waves in the accelerated creep zone. Defect detecting capability was identified when an ultrasonic wave flaw detection model is used for buried piping. In the pulse eddy current flaw detection, a coil most superb in totality was selected by means of simulation, by which corrosion and wall thickness of piping and devices were detected from outside the sheathing materials. Development was made on a technology to diagnose and evaluate corrosion of tank in operation by using the AE method. The remaining life of transformers is determined by how seriously the coil insulating paper has been deteriorated, and furfural in the oil was found effective for the parameters. Particularly, application of the NN was revealed to be effective in estimating electric motor deterioration. A high-temperature sulfide corrosion rate estimating model was developed from the operation and measurement data of the facilities by applying the NN and TCBM. (NEDO)

    Preliminary experiment, investigation, and study are conducted prior to an experimental 3-D MT (magnetotelluric) survey planned to be carried out in the Minaminoshiro district, Akita Prefecture. In the preliminary investigation, MT measurements were performed at nine locations. It was anticipated that national highways, waste treatment plants, high-voltage power lines, and railways in presence in the district would act as noise sources. Although the impact of such noise was detected in the single site treatment result, yet it was found that it would be mostly eliminated by use of the remote reference treatment. It was learned that the resistivity structure in this district was quite low in contrast or 1 ohm/m against 30 ohm/m, but the result of 3-D model calculation indicated that a sufficient analysis would be possible even in such a low contrast case. Furthermore, as the result of the study of the density of observation stations in the magnetic field, it was found that changes in the response of magnetic field to the resistivity structure would be approximately 2% at the maximum and that the ill effect on the result of measurement would be of the negligible magnitude even when a single magnetic field observation station is deployed against plural electric field observation stations. 6 refs., 7 figs.

    Research and development has been made on technologies to reduce sulfur content in light oil and on optimization of light oil quality. This paper summarizes the achievements in fiscal 2000. In the study of enhancing the desulfurization rate in gas oil deep hydrodesulfurization process, it was found that NiHY zeolite having Ni introduced by using the ion exchange method shows stable activity, whereas the target of sulfur content of 50 ppm or lower was achieved by adding the third constituent and by optimizing the impregnation solution to pH3. In the study of the Ni, Mo/alumina catalyst, the desulfurization activity was enhanced by optimization of carrier pore size to 120 to 140 angstroms and by addition of phosphorus and silica, having the target of sulfur content of 50 ppm or lower achieved. In the research of manufacturing low-sulfur light oil using heavy oil desulfurization and hydrocracking, optimization was performed on the catalyst used in the latter stage of heavy oil desulfurization, and evaluation was given on the performance in combination of commercially available hydrometallation catalyst/middle part HDS catalyst/bottom part HDS catalyst. As a result, achievement of the target of sulfur content in the desulfurized light oil of 300 ppm or lower was verified. Life evaluation test is in continuation on the heavy oil hydrocracking catalyst. (NEDO)

    In order to assure stable supply of oil and natural gas resources, and achieve enhancement in ocean development technologies in general, development has been made on the subsea petroleum production system (SBPPS), which is effective in ocean floor petroleum production from oil fields at great depths (300 m or deeper), and can be applicable to continental shelves and continental slopes around Japan. The SBPPS consists of four sub-systems of shafts, pipelines, manifolds, and riser and oil storage, whose basic development targets were established for the total system. The system was given a conceptual design for the total system, and the above four sub-systems were designed according to the conceptual design. The experimenting devices of each system were fabricated on a trial basis while fundamental studies are being made on component technologies, and experiments were performed to verify basic functions of the sub-systems. Developments were made on such operation technologies as the system operation technology, production control technology, safety control technology, and maintenance and repair technology required to operate the SBPPS. On-shore and general off-shore experiments were carried out to verify the functions of the experimenting devices of each system, the comprehensive functions and the operation technology. Comprehensive evaluation was given on the above achievements from the technical, economic and social viewpoints. (NEDO)

    In the last twenty-five years, the level of social recognition for the importance of energy conservation grew progressively from a total nonexistence of concern to the driving force that ensures the future environmental health of the nation and the world. Executive Order 12003, relating to energy policy and conservation, was signed by President Jimmy Carter and dated July 20, 1977. In 1992, President Clinton issued Executive Order 12759 - federal Energy Management. Each agency will prescribe policies under which its industrial facilities in the aggregate increase energy efficiency by at least 20% in fiscal 2000 in comparison to fiscal 1985. Current Federal programs for building efficiency are estimated to result in 31.5 billion dollars in annual energy saving for consumers by 2010. Future trends attract attention. The major programs currently in force to implement these policies and directives include Rebuild America, Million Solar Roofs Initiative, Home Energy Rating Systems, and Weatherization Assistance Program. 37 refs., 1 fig., 6 tabs.

    As the surroundings of objects of oil exploration grow more complicated, seismic survey methods have turned 3-dimensional and, in this report, several models are examined using the 3-dimensional simulation technology. The result obtained by the conventional wave tracking method is different from actual wavefields, and is unrealistic. The difference method among the fullwave modelling methods demands an exorbitantly long computation time and high cost. A pseudospectral method has been developed which is superior to the difference method, and has been put to practical use thanks to the advent of parallel computers. It is found that a 3-dimensional survey is mandatory in describing faults. After examining the SEG/EAGE Salt model, it is learned that the salt is well-developed and that 3-dimensional depth migration is required for sub-salt exploration. It is also found through simulation of the EAGE/S Overthrust model, which is an elastic model, that no quality records are available on thrust zones in complicated terrains. The records are poor in quality since the actually measured wavefield is regarded as an acoustic wavefield when it is an elastic wavefield. 1 refs., 18 figs., 2 tabs.

    In order to enhance the environment and wear resisting performance of the bearing mechanism for petroleum excavation bits assuming use at a depth of 6,000 m, discussions were given on a cubic boron nitride based ultra-hard thin film and a Ti{sub x}M{sub 1-x}N based hard thin film as the new materials. This paper describes the evaluation report for the year 2000. It was found that the promising material is the Ti{sub x}M{sub 1-x}N. The practical applicability test would require a considerable amount of expense and insurance fee, while putting the material into practical use would take some more time. However, the achievements in developing this new material will allow the material to be applied to cutting tools used under the same onerous condition, and theoretical development would be possible on the consideration of the film properties, whereas further development may be expected in the future. An international joint study has performed evaluations on the environmental resistance and the characteristics of the film at the University of Toronto. These evaluations are effective in enhancing further the properties of the thin film in the future. Achievements have been accumulated steadily from starting the fundamental studies, and high level objectives have been achieved. Accurate identification has been made on the state of developing the parts for petroleum excavation bits, with the objectives set properly. Putting the bits into practical use will still require public assistance. (NEDO)

    An oversea investigation was made in 1988 to study the present situation of the relaxation trends of petroleum resrictions in the countries of Western Europe. Among petroleum markets of West European countries, in those of West Germany and UK both quantity and price have had no restrictions. And in France they were liberalized quite recently. On the other hand, in South European countries such as Italy, Spain and Greece the prices of petroleum products are controlled by the governments. EC is going to integrate petroleum markets by the end of 1992 so that petroleum products may flow beyond the borders freely. In France, relaxation of restrictions on the petroleum industry was carried out in 1985 employing the petroleum business law of 1928 with elasticity and four years have passed since then. In Italy petroleum companies cannot decide the prices of major petroleum products freely. In Spain, the petroleum market is going to be completely liberalized in 1993 in accordance with the engagement with EC. Greece is at strife with EC on the adjustment of policies. 26 figs., 86 tabs.

    Blair`s cabinet of the UK, as soon as it was formed, started a review of all policies of the past Conservative government, including the area of energy and environment. The Labour Party has already underlined its commitment to promoting petroleum substituting, i.e., renewable energy. The government made clear that the unique British NFFO Scheme to promote sources of renewable energy would continue and in November, 1997 published the policy guide for the fifth round of NFFO bidding. The British energy market is generally considered to be the most liberalized for free competition in Europe and even the retail market for households is going to be completely open for competition in electricity and gas supply by 1998. As to the regulation of the green house gas exhaust, the Labour Party has put forward a target to cut 20% of the exhaust level of 1990 by the year 2010. The government is now preparing measures for its implementation. At present, the EU is debating the draft of the landfill directive. In the UK, the construction of waste incineration and power generating plants with modern technology is now being promoted. 27 tabs.

    A survey is conducted of energy-saving and greenhouse gas reducing measures in cooperation with the National Petrochemical Public Company Limited (NPC), Thailand. The NPC is the first petrochemical producer in that country and, after 10 years' operation, the largest such producer there. Transfer of energy-saving technologies from Japan will lead to the construction of clean development mechanism (CDM) in the future. The NPC plant surveyed is situated in a Maptaphut industrial complex, and produces ethylene propylene from natural gas and at the same time serves as a utility center to supply electricity and steam to factories and plants in the vicinity. Items examined involve waste heat power generation, power generating gas turbine efficiency improvement, ethylene plant cracking furnace heat retaining capability enhancement, steam pipe heat retaining material renewal, and replacement of obsolete air conditioners with higher-efficiency equipment. After tentative calculation a conclusion is reached that the total of energy-saving effects of the said five items will be 21,900 tons/year in terms of crude oil and that a CO2 reduction will be feasible at a rate of 45,300 tons/year. These figures are larger than the ones predicted before the survey. A total of 354.3 million bahts will have to be invested. Negotiations will continue with attention directed to the progress of NPC's preparedness to accept CDM. (NEDO)

    The present developmental conditions of petroleum substituting energies in the U.S.A. were surveyed. The budget related to energy saving and petroleum substituting energies in the U.S.A. is on the increase. DOE`s expenditure on petroleum substituting energies increased from $6.8 billion in 1993 to $8.1 billion in 1995 (from 29.6% to 34.6% of DOE`s expenditure), showing the positive approach to development of petroleum substituting energies. Approaches to environmental protection are also in promotion such as positive use of electrical vehicles by U.S. government and emission regulation of specific pollutants by EPA. The state of California withdrew the regulation which prescribes that 2% of passenger cars sold in the state should be zero emission vehicles after 1998, because development of the battery with both sufficient mileage and output is impossible by 1998 in the present stage. The prospect of practical use of new batteries such as lithium battery is still far from certain for some years. Development of petroleum substituting energies in the U.S.A. is still insufficient. 17 refs., 1 fig., 4 tabs.

    Looking for effective policy on petroleum substituting energy, measuring models were made for analyzing relations between changes in social structure and energy supply/demand structure. Through the simulation using these models, effects of difference in energy policy on economy and energy supply/demand were studied. Countries for survey were Thailand, the Philippines, Indonesia, Malaysia, China and Korea. The measuring model is composed of the macroeconomic model and the energy supply/demand model. In the case of Korea, the interindustry-relations model was added. Using the macroeconomic model, asked were fluctuations in various economic activities/industrial structure/price/trade balance such as GDP and crude steel production by inputting overseas indices, population indices and financial indices such as the world trade, crude oil price and exchange rates. In FY 2000, for ASEAN countries, data were collected for analysis of relations between changes in economical/social structure and energy supply/demand structure. Using the pilot model constructed, the simulation was made on the standard case. (NEDO)

    The paper described the FY 1998 results of the development of bioinformatics. All structure/sequence known proteins from all public databases were hierarchically classified systematically and according to similarities among sequences. Individual proteins in each classified group were added with explanatory notes of structure and physiological function. The mutually related information in metabolic system/signal transfer system was also included. The state of each residue position was classified into three states in terms of the solvent accessibility and three states in terms of the secondary structure. Parameter sets of occurrence frequency for each state of 20 kinds of amino acid were made. By these, it can be evaluated how much the arbitrary amino acid sequence is suitable for each structure in database. The data on the structure of low molecular-weight compounds are also incorporated so that the search for the related biomolecular system information becomes possible. The metabolic system/signal transfer system information was made database, the link was formed between each protein and each low molecular-weight compound, and the information on biomolecular networks was made searchable. A system to predict/support protein structure and function was developed. (NEDO)

    Applying the hydroponic biofilter method as a direct purification method for a hyper-eutrophic lake water, an experiment was carried out at the Tsuchiura Port on Lake Kasumigaura to obtain data for constructing a hydrophilic artificial wetland. Purification of hyper-eutrophic lake water containing a large amount of water blooms in summer was attempted applying the hydroponic biofilter method for which hydrophyte is used. As a result, it was clarified, by applying the hydroponic biofilter method, that capturing effect of suspended substances can be achieved in the rooting zone, captured suspended substances are decomposed at high rate, and the revolved nutrient salt can be absorbed and assimilated by the use of plants having high growth rates. Ipomoea aquatica had the highest removal activity, followed by nasturtium officinal, menthe spicata, and oenanthe javanica. As a result, it became clear that a constructed wetland made with the hydroponic biofilter method can be applied as a direct purifying method for hyper-eutrophic lake water by selecting appropriate plants in accordance with season. 18 refs., 1 fig., 4 tabs.

    Discussions were given to reserve global environments on reducing dependence on fossil resources and more effectively utilizing wood resources. Economically utilizable amount of wastes from lumbering factories reaches about five million tons annually. Discussions were made on a ligno-bioprocess that uses these wastes. The current quantitative production efficiency of cellulase by means of bacterial breeding is very high. A problem is production of ligninolytic enzymes, to which application of the recombinant DNA method is indispensable. Combination of steam explosion with biological decomposition or the organosolv process is an effective method for lignin decomposition. Decomposition of cellulose by using the ultra critical water method is worth noticing. With respect to hemicellulose utilization, production of cellulose derivatives, biodegradable polymers and oligosaccharides would be conceivable by means of esterification and etherification. Vanillinic acid, adhesives, resins and lignin-based polymer materials could be manufactured from lignin. Material cost for these products accounts for about 35% of the product price, thus making the lignochemicals promising commercial products. 301 refs., 71 figs., 39 tabs.

    The technique now in use for disinfecting municipal sewerage is the free chlorine method, and the free chlorine reacts with ammonia in the treated water for the formation of NH4Cl. The resultant compound is strongly toxic and harms aquatic organisms, this creating a knotty problem to solve. In this report, a bioassay utilizing Porphyra yezoensis conchospores is performed, and the toxicity reducing effect is discussed of the seaweed on water specimens disinfected by free chlorine, chlorine dioxide, ozone, and ultraviolet rays. Porphyra yezoensis is easy to acquire, and the bioassay evaluates the toxicity of the water specimens by evaluating the survival rate of conchospores discharged by free-living conchoceles and the rate of inhibited sprouting. The outcome is summarized below. The injection dose required for inactivating 99.9% of the groups of coli bacteria in the treated water and the trend of fluctuations in the concentration level are obtained. No inhibition of conchospore sprouting occurs even with the addition of 100% of treated water in the chlorine-disinfected specimen or chlorine dioxide-disinfected specimen. 19 refs., 8 figs., 2 tabs.

    This paper describes an algorithm for calculating the equilibrium state of carbonate system in seawater. The photo-synthesis, respiration, and basic production ability of organic and inorganic carbon compounds by calcification of coral reef ecosystem and the change in carbonate system in seawater were discussed. The carbonate system in seawater can be estimated by determining two variables among the four variables, i.e., pH value, total carbonate, total alkalinity, and partial pressure of carbon dioxide (PCO2). The analysis program proved to give good agreement with the previously calculated results. In the inorganic production of carbonate in seawater, one mole of carbonate precipitation liberates approximately 0.6 mole of CO2 into the air, and the pH value shifts toward acid side. The experimental value (0.55) for production speed ratio of inorganic carbon to organic carbon in the seawater where the coral family is abundant brings about the increase of the organic carbon production, resulting in the decrease in PCO2 in seawater and the increase in pH value. It is assumed that it becomes of a sink of CO2 in the atmosphere. 23 refs., 3 figs., 7 tabs.

    This paper describes photosynthetic function of plants, and CO {sub 2} fixing function of marine organisms. Among the photosythetic reaction systems, the C {sub 3} type reaction carries out CO {sub 2} fixation using the Calvin cycle, and takes out the carbon dioxide out of the system through enzymatic reactions of 3-phosphoglycerate {yields} fructose-6-phosphate. The C {sub 4} type reaction has a special cycle to supply CO {sub 2} to the Calvin cycle, i. e. C {sub 4} dicarboxylic acid cycle. The CAM type reaction enables the photosynthetic type to be converted according to variations in the growing environment. The majority of the surace agricultural crops are from C {sub 3} plants, of which yield may be increased when grown in a high CO {sub 2} atmosphere. On the one hand, gene engineering may make possible breeding of plants having high CO {sub 2} fixing capability. In the area of marine organisms, lime algae growing in clusters around coral reefs form and deposit CaCO {sub 3}. Reef creating corals have symbiotically in their stomach layer brown algae having photosynthetic function to build CaCO {sub 3} skeleton. The corals calcify algae quickly and in a large quantity, hence play an important role in fixing underwater CO {sub 2}. 2 tabs.

    This paper describes the following matters related to amendment of oil related systems which will be enforced according to the result of discussions at the Petroleum Council on the ways the oil product supply should be in the future. The temporary measure law for importing specific oil products shall be abolished when it will be expired in March 1996. This is because the law has limited the oil product importing organizations only to oil companies who have oil refining capabilities, and the continuation of the law would lose its justifiability under the present circumstances in the petroleum industry. The oil reservation law is then amended so that the emergency handling ability on oil supply will not be hampered even after possible expansion in the number of oil product importing organizations as a result of the abolishment of the temporary measure law. The quality management systems for oil products will also be revised so that the present level on quality items of the minimum necessity will not be declined with respect to the environments and safety. Furthermore, the area designating system that has been limiting erection of oil service stations will be repealed by October 1996. 2 tabs.

    With relation to the coal of the Philippines, where the expansion of the use of coal as a substitute for petroleum/plant fuel is aimed at, the paper grasped the situation of coal production/development, the trend of coal import and domestic distribution, the coal utilization trend, and environmental problems, and analyzed the situation of coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to draw up a master plan for the introduction of the environmentally-friendly coal utilization system. As to the use of environmentally-friendly coal technology which should be adopted to the coal mining industry and commercial/residential sector, cited are the introduction of coal preparation technology and power transmission technology, and the development/spread of briquette as a firewood substituting fuel. In the electric power sector, the problem is the treatment of ash after combustion and the effective use. Relating to the treatment of flue gas, there is no installation at all of desulfurization facilities and denitrification facilities. In the cement industry sector, they wish to return fuel from heavy oil to coal. For it, it is necessary to study dust preventive measures. In the other sectors, coal hasn`t been used very much. An increase in coal demand is not expected also in the future, and big problems concerning coal haven`t occurred. 42 figs., 64 tabs.

    A development was intended of an alga reef block that is suitable for adherence of algae and difficult of shore-burning by utilizing coal ash. Concretes with different coal ash displacement rates were used to install alga reef blocks embedded with natural rocks, steel plates, and the used desulfurizing agents on three areas (the Usubetsu area, the Tamagawa offing, and Chatsu Bay) including shore-burned sea areas along the coast of Tomari Village. Investigations were made on the states of adherence of useful algae as a result of difference in materials and locations of installation. The best adherence of edible kelp was observed at the Usubetsu area, followed by the Tamagawa offing and Chatsu Bay in that order. Growth conditions of the kelp by locations were conceived of the correlation with how extensively the natural kelp colonies are formed around each location, and how many nutrient salts are present and sea urchins are grown. No remarkable difference was observed in the adherence of algae due to the difference in the coal ash displacement rates. Porous blocks, however, showed less adherence amount. Kelp adherence condition was found good in the order of concrete, natural rocks, and the used desulfurizing agents. No kelps have adhered on the steel plates. 10 refs., 13 figs., 3 tabs.

    A survey was made in India which is a coal producing/consuming country following China in Asia and where coal is used for about 60% of the primary commercial energy. The survey was conducted on coal production/distribution/utilization and environmental issues, aiming at studying feasibility of introducing the environmentally friendly coal utilization system into every industry including the residential/commercial one, and at implementing a comprehensive master plan including Japan`s international cooperation. Total power source facilities in fiscal 1995 are 83.3 million kW, 64% of which are coal thermal power facilities and generated 260 TWh, 69% of the total output energy. Main commercial energy sources are coal, oil and natural gas, and oil is self-sufficient. The survey this time did not examine very well the actual state of the environmental pollution problem caused by the coal utilization. Indian coal is high in ash content but low in sulfur content, and therefore, SOx polluting air has not been a very important problem so far, but soot/smoke is almost the problem. Further, ash treatment after combustion at boilers, etc. is expected to be a big problem in the future. 49 figs., 88 tabs.

    Discussions were given on mass cultivation in a water tank using sea water of an alga Ulvales used as feed for sea urchins and abalone. A fertilizer composed of ammonium sulfate and superphosphate of lime was used, and a water temperature was set as the environmental condition. Two kinds of Ulvales produced in different areas were used. One of the two kinds had full growth periodical and weight increasing rate low, but the other Ulvales had high weight increasing rate and no blights in alga bodies, and was found suitable for mass production. The result of a test on stocks of the latter species may be described as follows: multiple regression formulas for harvest, water temperature and illumination intensity were introduced for each cultivating condition for four cases regarding accommodation density and harvest frequency; and if a cultivating condition by which the harvest is maximized is adopted, a one cubic meter water tank placed on a place with good sunlight may be expected of producing as much harvest as 2181 grams at water temperature of 15{degree}C and 4899 grams at 25{degree}C. The cultivation requires the following precautions: aeration is required; sea water should be introduced into the tank; a mixed fertilizer with ratio of ammonium sulfate at 100 to superphosphate of lime at 15 may be used; water temperatures suitable for mass cultivation are 13 to 15{degree}C or higher; and light must be irradiated evenly. 14 refs., 9 figs., 5 tabs.

    Processing of a large amount of coal ash is a serious problem in considering the locational conditions of coal firing power generation plants. 46% of the coal ash was effectively used in 1985, and the remaining 54% was disposed at landfills on land and sea. Positive promotion of the effective use of coal ash is the necessity. A production method for an artificial lightweight aggregate utilizing coal ash was established by a joint research. The history of the research and development of this artificial lightweight aggregate (brand name: FA-lIGHT), outline of the manufacturing facilities, physical properties and result of use are introduced. The lightweight aggregates are used not only for the construction of multistoried buildings but also used as most suitable aggregates for making lightweight large scale panels and concrete secondary products such as lightweight blocks. FA-LIGHT is most suitable for use in the production of concrete lightweight aggregates, and can be used for hydroponic agriculture and for the improvement of drainage of land. Spread of its use is expected. 5 figs., 5 tabs.

    Mitsui Kushikino Mine previously processed two gold ores from Kushikino and Iwato ore deposits by the all slime cyanidation method, where the ores were ground to fine size smaller than 75 {mu}m and leached with sodium, cyanide. A large amount of slimes were produced as waste and discarded in tailings ponds. To save the costs of grinding and waste treatment it is desirable to process coarse sized ores. The Iwato ore is gold and silver bearing silicified porous rock. As most gold and silver in the Iwato ore are concentrated in the pores, leaching of coarse sized ore is expected to be possible. Laboratory tests and pilot plant tests of vat leaching for the Iwato ore were carried out using 0.15-8.0 mm feed. These results showed that the gold dissolution rate was similar to that by the all slime cyanidation and the decrease in gold recovery was a few %. The properties of these tailings can be used in fine aggregate of concrete. Based on the results vat leaching of the Iwato ore was adopted in the plant. The tailings are sold and used as fine aggregate. Utilization of slime tailings from the other ores was also developed and they are used as flux in copper smelters. Now, there is no tailings pond at Mitsui Kushikino Mine. 9 refs., 10 figs., 5 tabs.

    The technical art `Bekko` is one of the traditional technologies in Japan, and the materials of `Bekko` are shells of hawksbills. However, the industry of `Bekko Work` has been facing a crisis recently, because the import of turtleshell is restricted. We have therefore tried to develop new materials as substitutes for the turtleshell by utilization of horn. The noteworthy aspects in this study are as follows: (a) It has been clearly established that the horn could be reformed with amber color similar to that of turtleshell by chemical treatment using hydrogen peroxide (H2O2). (b) It is also of interest that we produced new materials like `Bekko` by mixing horn powder and turtleshell powder at the appropriate ratio and molding them in the temperature range of 110-120{degree}C. 1 ref., 6 figs., 3 tabs.

    Several kinds of silica gel modified by alkoxyalcohols were synthesized by refluxing and dehyration and the organic reactions were studied when these silica gels were used as the catalyst. It could be confirmed by FT-IR spectra, DTA and elementary analysis that alkoxylalcohols adhere to the surface of silica gels without any decomposition. The acetate was produced by using alkyl halides. It was found that the modified silica gels had clearly the catalytic action for the reaction with n-hexyl bromide and dibromoethane although unmodified silica gels did not show the catalytic action. The reducing reaction of carbonyl compounds was carried out. The reaction proceeded at 25 centigrade for acetophenone, cyclohexanone, 1-indanone and 2-octanone to produce the corresponding reduction products. 11 refs., 5 figs., 4 tabs.

    The coal cartridge system (CCS) is a series of the total system, in which coal is processed centrally at a supply base for each unit of consumer areas, supplied as pulverized coal in bulk units, and coal ash after combustion is recovered and treated. The system is expected of advantages resulted from the centralized production, elimination of handling troubles, and cleanliness. Following a small scale demonstration test, a large demonstration test for practically usable scale has begun in 1990, and completed in fiscal 1995. This paper introduces the CCS and reports the result of the test. In the large demonstration test, a supply station (with manufacturing capability of 200,000 tons a year) was installed in the Aichi refinery of Idemitsu Kosan Co., Ltd., and systematization on quality design and system technologies has been carried out. Long-term continuous operation for five years was achieved (operation time of the supply facilities was about 19,000 hours) without a failure and accident, to which every elemental technology was evaluated highly, and convenience and reliability of the system was verified. 13 figs., 3 tabs.

    In order to utilize more effectively coal ash whose generation amount is increasing year after year, studies have been made on a technology to manufacture and utilize a high-strength substance solidified under normal temperature by utilizing hydration reaction of pozzolan system (Poz-O-Tec). The study works have been done as a subsidy operation of the Agency of Natural Resources and Energy, and were completed in fiscal 1995. Poz-O-Tec is a wet powder made of coal ash and stack gas desulfurization sludge (gypsum) added and mixed with lime and an adequate amount of water, which solidifies by hydration as pozzolan does. The same method as used for ordinary sands may be used as the basic application method. Because this is the material whose strength increases after construction, thickness of construction may be reduced smaller than in constructions using soils and sands. Test constructions of about sixty cases have been carried out to date, typically represented in use as a road bed material, banking, and a base material for water-barrier gutters. High-strength solid material which is stable under normal temperature may be obtained by adjusting calcium content. As a result of its effectiveness in practical use having been verified, a certificate of technological judgment has been issued for the material by the Civil Engineering Research Center. 3 refs., 11 figs., 2 tabs.

    An overview is given on the development situation of a Zn-Br battery as a power storage system. The system is aimed at storing excess power at night and supplying the on-load demand during daytime. The power storage technology requires a large output and capacity of MWh level, long term stability and durability, and cost as low as pumped storage power generation. Four kinds of batteries have been examined to cope with the conditions, in which development of Zn-Br batteries along with Na-S batteries is in progress towards practicability. As a power conversion method for this system, GTO has been employed for a large capacity unit and IGBT for a medium/small capacity unit. The reliability of the Zn-Br batteries against leakage was improved by laminating each cell by hot plate welding. The service life was improved by using a material with a high bromine resistance in place of the conventional electrode constituent material. Although the battery efficiency was influenced by each resistance of electrode, film and electrolytic solution, distance between electrodes, temperature, etc., these correlations were clarified so as to establish the simulation technology. At present, the system realizes 50kW and 40kWh/m{sup 3}. 1 ref., 8 figs.

    Entrails of fish, fowls and domestic animals are mostly incinerated at large expenses, although partly used as foods. This study is to test `possibility of vegetable cultivation with fish breeding water,` where the entrail wastes are used as baits for fish breeding, and fish excretions are used as the fertilizer for vegetable cultivation to purify water for fish breeding. The cultivation bed consists of two sections, one for fish breeding/vegetable cultivation and the other for vegetable cultivation by the normal method. Vegetable grow notably less in the former than in the latter, 54.6 to 79.5 versus 100. Spinach contains slightly higher contents of vitamins A and C by 6 and 13%, when cultivated in the former than in the latter. Quantities of total nitrogen, phosphorus and potassium as the fertilizer components in the former are 49, 49 and 1.7% of those in the latter. It is predicted, judging from growth of the vegetables, that the former gives a harvest comparable with that by the latter, when given a 6 to 13 days longer cultivation period. 3 figs., 2 tabs.

    Although a part of the entrails of fishes, birds and livestock is used for food, most of them are treated by costly combustion because of their bad odor and looking, and International Environment and Welfare Laboratory, Toyama prefecture in Japan is studying their profitable treatment. As a part of such study, possibility of hydroponic cultivation of vegetable was tested using fish breeding water including excretions of fishes and residual feeds after use of waste as feed, and the growth condition, safety and effectiveness of cultured vegetable were verified. Three-hundred and fifty viviparous Oryzias were released into a breeding water area with no controlled pH and EC (electric conductivity). For comparison a culture solution area of 6.0 in pH and 1.2ms/cm in EC was prepared. The result on cultivation of 6 kinds of vegetable in culture beds supported by circulation of these water showed that hydroponic cultivation of vegetable using fish breeding water is possible, and average growth of 68% is obtained although difference in growth for every vegetable is found. 8 figs., 5 tabs.

    In relation with coping with global environmental problems in recent years, needs are increasing more than ever for enhancing fossil energy utilization rates, developing and expanding utilization of petroleum substituting energies that can substitute fossil energies. Since Japan is particularly a large energy consuming country, and cannot escape from depending on import for the majority of its energy resources, it is an urgent issue to enhance the energy utilization efficiency and further promote development and utilization of new energies. To do this, it is indispensable to exchange such item of information as identification of actual status in other countries of handling the petroleum substituting energies. Taking up geothermal energy, fiscal 1998 invited four experts from EU countries. Visits were made for about two weeks on Japanese research institutes and business enterprises related to geothermal energy, and opinions and information were exchanged. A seminar was held on the final day, where the EU experts have made presentations on the current status and future prospects on geothermal research and development in EU. Greatly valuable suggestions were given for the Japan's future geothermal research and development. (NEDO)

    The result is reported of a TDEM method-based survey for oil exploration conducted in the Yoneyama district, Niigata Prefecture. The survey covered the southern part of the sedimentary basin in the prefecture, known for the poor quality of the seismic prospecting data that had been recorded. The purpose of the TDEM method-assisted survey was to probe the high-resistivity volcanic rock structure and low-resistivity sedimentary layer, and to know their details. The obtained data were subjected to interpretation by use of the 1D inversion method. A 4000m-deep level was subjected to interpretation, 34 data were inputted, and the early model consisted of 20 layers. As the result, it was found that there was a high-resistivity layer ranging from the ground surface down to a depth of approximately 500m, that a low-resistivity layer 2500-3000m in thickness lay thereunder, and that the lowest layer had a high resistivity of approximately 100 Ohm m. By comparing these data with the geological structure, structures were disclosed corresponding to the rock bed depth, Ukawa syncline, Ishiguro anticline, and Yoneyama mountain mass. 3 refs., 10 figs., 1 tab.

    Since 1987, petrochemical industry has jumped into the era of properity and as a whole, been supported by increasing demands. Although it is said that the 21st Century is the age of chemistry, but for petrochemistry the age of 1990 {prime} s is the age of international competition for the survival towards the 21st Century. The scale of individual enterprise of the Japanese chemical industry including petrochemical enterprises still remains small when compared with that of the individual world-wide chemical enterprises of the U.S.A., Germany and the U.K., etc., besides these world-wide enterprises have established their production bases and research facilities in Japan. In addition, there is somewhat uncertainty in the foundation which is supporting the present prosperity. This article scans the present situation of petrochemistry in its preface, explains the present state and trends of individual industry in the chapters covering the environment around the Japanese petrochemical industry, the report (summary) of the Long Term Credit Bank Institute of Management, trends of advance of oil industry into petrochemical business, production capacity of ethylene and new as well as additional plant construction plans. In this industry, is observed the constitution of Japan which is unable to form internationally competitive power irrespective of her recognition of its necessity because of their giving priority to the balance of their business world. 1 tab.

    The technologies are developed for efficiently, economically improving quality of automobile fuels by, e.g., abatement of environmental pollutants present in the oil products. For improvement of hydrodesulfurization rate of gas oil deep hydrodesulfurization process, the catalyst components high in isomerization ability of the hard-to-desulfurize compounds are investigated, and effectiveness of zeolite is confirmed. For production of low-sulfur gas oil by hydrodesulfurization and hydrocracking of heavy oil, the catalyst with small pores is preferable for desulfurization of gas oil as the co-product of the treatment of heavy oil in the presence of catalyst for heavy oil desulfurization. For hydrocracking, the catalysts are prepared, on a trial basis, for achieving the target gas oil sulfur content of 10ppm or less by optimizing the zeolite and matrix properties. For suitability of gas oil qualities, it is found that the hydrogenation step is the rate-determining step among the reaction routes involved in the hydrogenation of difficult-to-desulfurize compounds. The data of low-sulfur gas oil qualities in Europe are collected. (NEDO)

    At present, in oil refineries in Japan, the term of the continued operation in oil refining facilities is shorter than that in Europe and America because of the regulation on the open inspection period for boilers and hazardous material storage tanks. As a result, the refining cost is comparatively higher than in Europe and America due to the increase in inspection/repair cost and decrease in operational rate. Therefore, it is becoming important to effectively supply petroleum products by keeping stability in oil refining facilities of the whole Japan and prolonging the term of the continued operation of oil refining facilities, etc. In this R and D, the technical development is conducted which is needed for the long-term continued operation of oil refining facilities. The items for the R and D are as follows: assessment technology of reliability of oil refining high temperature system facilities, assessment technology of reliability of piping/storage facilities in oil refinery, assessment technology of reliability of oil refining power system facilities, technology of management support system in oil refining facilities. In this fiscal year, technical survey, data collection, and construction of the basic concept of developmental technology were mostly conducted. Also conducted were trial manufacture of various probes for non-fracture inspection use, oscillators, etc., and basic design of inspection equipment and trial manufacture of a part of them. And the data acquired were analyzed. (NEDO)

    Described herein are results of evaluation of the developed excavators remotely controlled for highly deep submarine oil fields. The excavator system was designed to work at the target water depth of 200 to 250 m and excavation depth of 8,000 to 9,000 m, though not quite satisfactorily. There were several practical problems to be solved, e.g., those found in accuracy of reentry in the excavated section, cables connecting the driving equipment to the excavated section, and entangled hoses. The works were divided and system was configured in an attempt to secure all-weather type serviceability and to improve economic viability. The other major works included attempts to improve equipment functions and reduce manpower cost. Nevertheless, however, the construction cost was considered to be higher than expected, and no firm prospect was obtained whether the new excavator system was economically competitive with the conventional rig. The factors that pushed up the construction cost were various facilities needed by the new system with the separated excavation and driving sections, e.g., those facilities for helping the system land on the sea bottoms, material supply/storage facilities, and automated/unmanned facilities. The system failure and other items related to reliability are no clearly understood, making it difficult to compare it with the conventional rig in service factor. It was not adequate, therefore, to advance the next R and D phase as planned, and decided that the project was suspended to see the world development trends, because the clear plans for the future could not be drawn at that time.

    A survey is conducted for the above named plant under an energy saving project expected to link to the clean development mechanism (CDM) of COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). Studies are conducted about the refurbishment of the existing power recovering facilities in the wake of a plan for enhancing FCC (fluid catalytic cracker) processing capability and about power recovery from unused exhaust gas from the RFCC (residual fluid catalytic cracker) second catalyst regeneration tower. A modification plan was drafted and rough designs were prepared therefor, and it was found that power recovery from RFCC would be technologically and economically unfeasible because of the high temperature and extremely small quantity of the recoverable gas. It was then concluded that the plan be abandoned. Thanks to the refurbishment of the existing power recovering facilities to go out of service under the new operating conditions after FCC facility modification and to the installation of a new exhaust gas processor for air pollution prevention, there will be 10.6MW to be recovered for a reduction in fuel for in-house power generation. The consequential reduction in energy consumption will result in a CO2 reduction of 70,000 tons/year. Though China has not yet ratified the COP3 protocol, it is hoped that it will consider emission tradings and participate in the project when designated as a CDM country. (NEDO)

    The experiment and survey were carried out to verify the effectiveness and limitation of MT method. The previous seismic reflection method is unsuitable for steep terrain and over-folded complicated geological structure. In such difficult areas, application of MT method is increasing as complement or substitution for the reflection method. However, the evaluation of resistivity structure interpretation for every area is slightly difficult because of lack of data, poor quality of data, and no verification data at boreholes. Consequently, the survey was again carried out in well-known Yurihara oil and gas field, Akita prefecture whose geological structure has been surveyed in detail at boreholes, by adding new 32 sites, 22 sites on the south side and 10 sites on the north side of the measuring line extending from east to west. As a result, it was clarified that the lower high-resistivity layer found by MT method is equal to the Nishikurosawa basaltic layer, and basalt extends to the west in the north area. This result can`t be simply compared with the previous geological profile. 8 refs., 8 figs.

    This paper describes the current actual conditions on treatment of bilge discharged from engine area and oily drain water from cargo area of tankers. Clean bilge among various bilges discharged from engine area such as vapor drain, fresh water, rainwater, seawater and condensed water is directly dumped into the sea after temporary storage in a clean tank. Oily bilge is produced mainly by mixing of clean bilge and leakage oil from main engines and various auxiliaries. Oily bilge is dumped into the sea under comparative monitoring of the bilge quality with the dumping standard by oil concentration monitoring and control equipment after the primary treatment in a treatment tank and the secondary treatment in a bilge separator. Oily drain water from cargo area contains water ballast for cargo oil tanks, wash water for tanks and lines, and bilge produced in pump room. The oily drain water is dumped under a specific condition. However, water ballast for specific ballast tanks is excluded from the oily drain water. 2 figs.

The energy conservation effect is approximately 0.91 million tons/year of crude oil. The effect of reduction in greenhouse gas emissions is CO2 2.83 million tons/year. A plan on system interconnection, distribution, electricity, instrumentation control was drawn up. The construction term is planned to be about two and a half years. The initial investment amount is 700 million yuan {+-} 100 million yuan. The expense vs. energy conservation effect was calculated as 98t (crude oil conversion)/year/million yen, and the expense vs. greenhouse gas emission reduction effect 302t-CO2/year/million yen. Concerning the profitability, the generating cost was 0.4 yuan/kWh which dropped from the selling power cost of the Yanshan area, 0.45 yuan/kWh. As candidates of the natural gas fueled cogeneration, there are possibilities of 10 sites and 550MW scale only in the Beijing area. (NEDO)

    In a servo PD (positive displacement) flowmeter for oil, a differential pressure transmitter detects difference in pressure between the PD flowmeter input and output ports and a rotor is driven by a servo motor so that the pressure difference between before and after the PD flowmeter rotor will be zero. The design enables high-accuracy measurement across a wide range of flow rates and is not easily affected by the surrounding physical conditions such as viscosity and density. For the development of such a flowmeter, it is necessary to develop a rotor that rotates smoothly free of locking in a steady and uniform flow, to build a visualized model that enables the analysis of flow inside the flowmeter which in turn will enable the determination of optimum differential pressure detecting ports, and to connect a newly developed servo mechanism to the thus determined ports. As the result of the research, a servo PD flowmeter is developed, which is a 50mm diameter prototype employing the Invoflex tooth form which is the waveform for a rotor suitable for a high performance flowmeter. Placed in a generally used oil flow calibration liquid, which is gasoline, kerosene, or the like, it covers a flow rate range of 1:10 and reads with an accuracy of {+-}0.1%. It remains stable in performance and suffers but a little change with the passage of time. (NEDO)

    This report describes the results of effective fixing technique of CO2 by utilizing solar energy. First of all, the investigation was directed to the technique for synthesizing ethylene, hydrocarbons and alcohol by electrochemical reduction of CO2. The power required for this process is supplied by photovoltaic power generation. Development of excellent electrode catalyst is needed because the reduction of CO2 requires a high overvoltage. It is desirable to enhance the selectivity of the reaction for specific material and improve the transport process in the electrolytic cell. Next, designing of material and reaction of photocatalysts using semiconductor electrode and semiconductor particulate was examined. A semiconductor electrode made of FeS2 is inexpensive and has a high ability of collecting solar light. In the category of photocatalysis system, a photocatalytic system in which semiconductor particles are embedded in vesicle and a photpocatalyst based on potassium niobate are noteworthy. As biosystem, the method of reducing CO2 by calcareous algae which simultaneously advances fixing and calcification of CO2 by photosynthesis is noteworthy. 129 refs., 45 figs., 20 tabs.

    For every solar energy utilization field, its background, feasibility, impact in practical use, and R and D policy in Japan were studied. Heating and hot water supply by solar energy are already practical because of less technical problems and reasonable profitability, and cooling is also practical as far as a technical viewpoint. At present, the technical level of solar heat power generation is in the stage of basic technology, however, in the future, development of economically reasonable systems will be demanded as well as establishment of its technology. The most difficult problem for realizing practical solar cell power generation systems is cost reduction. It is also another problem that a big demand of Si for solar cells further exceeds the current yield of Si in a semiconductor industry. A small-scale hybrid solar cell power generation system applicable to the roof of general residences is already feasible. Although a solar furnace is still poor in application to industrial fields, it is expected as the leading part for a future solar heat chemical industry. (NEDO)

    Rice being produced as food is taken up out of various types of biomass, and a feasibility study from the viewpoints of technology and economy is conducted as to its use in the energy industry. The production of ethanol from rice, though it has no past record worth discussion, is similar to the production of ethanol from other biomass resources in terms of technology and economy. The problem is that the production cost of rice is far higher than those of other materials. It is expected, however, that there will a large-scale production cost reduction and an increase in the yield when novel cultivation techniques are introduced in the future. It is also expected that alcohol from rice will be sufficiently competitive with alcohol from molasses or the like when the exploitation of cellulose-family by-products such as husks becomes feasible. The study on this occasion deals solely with the effective use of farmland and the surplus rice. A confrontation between rice as a biomass resource and rice as a food has to be avoided as much as possible in the long term because it may cause a price rise and compromise the security of food supply. That is, in discussing this matter, it is mandatory to draw a very definite line between rice as a food and rice as an alcohol production material. (NEDO)

    Imagining a space in the middle of the 21st century, a space station installed with the artificial gravity generation facility is constructed, and a space factory utilizing a gravity free environment is also constructed. The construction materials for the space structures of this kind are prepared from the resources of the Luna. A solar power generation satellite being arranged with the solar cells manufactured from a silicon of the Luna is allocated on a geostationary orbit, and a power generated is supplied to the earth by the microwave. In such a time, a regular liner to the Luna and a ferry boat to the Mars will have come to fly, and furthermore an oxygen used for the propellant to them as well will be supplied from the Luna. In order to realize such a conception, there are various problems to be overcome such as a transportation problem first of all, a long life problem in the Luna and Mars bases and so forth. Furthermore a consideration to the environmental conservation of the Luna and Mars is also required. The nature of the Luna without a crustal alteration, meteorological phenomena, and organisms has no force to restore an environmental destruction. As for a space development in the future, it is desired that it should not damage a nature of the space and should be a field to chase a possibility of the human beings for a long time. 30 refs., 14 figs., 1 tab.

    The result is reported herein of a depth transform algorithm application utilizing equi-traveltime planes in reflection seismic exploration for the purpose of knowing the structure configuration in front of the tunnel face in a tunnel excavation process. A vibration producing hole was provided 0.5m above the ground surface while a vibration receiving hole was provided at 1.5m above the ground surface, and the excavated lengths were 1.5m and 0.5m, respectively. There were 24 recording channels, from which inline offset records were taken. The on-site records were subjected to 100-1000Hz band pass filtering. The elastic wave propagation rate in the rock used for depth conversion was set at 400m/s in consideration of the distance and direct wave travel time from the vibration source to the vibration receiving point. As the result of study, weak layers were found in the neighborhood of 230-240m, 260-270m, and 280-290m. This method requires less core memory for calculation and completes calculation in a shorter period of time, which enables a conclusion that it will be effective in grasping the 3-dimensional structure in front of the tunnel face in the working scene. 4 refs., 7 figs.

    Studies were made for developing low-pollution easy-to-operate industrial furnaces for use in small and medium size plants in Indonesia. In this fiscal year, two kinds were selected out of Indonesia yielded brown coals, which were then subjected to test combustion in a bench scale fluidized bed combustor for examination for their combustion characteristics and environmental impact generating characteristics. The nitrogen oxides from the brown coals were found to mark approximately 100 ppm at an excess air ratio of 1.4, which was higher than in the case of bituminous coal. The NOx concentration level was found to be lower in the circulation fluidized bed boiler than in the spreader stoker fired boiler. Combustion efficiency exceeding 98% was achieved. A survey was conducted of brown coal users in various industrial fields in Indonesia. It was then concluded that the tested method not be recommended for use in small businesses in the textile industry because there would be no economic profit or improved efficiency for them but that it would be feasible in the plantation industry where the fluidized bed combustion/heat exchanger aided indirect process and the use of electrical dust precipitators would protect products from contamination.

    As for a preventive countermeasure against the global warming, experiments and studies have been conducted on the bioreactors to fix carbon dioxide gas recovered from the concentric and large scale generating sources such as thermal power plamts in a form of carbohydrate by means of the culture of microbial algae. By using the Vertical Tube Reactors (VTR) culturing apparatus, a variety of microbial algae were cultivated and experiments were performed on the relationship of biomass productivity and absorption rate of carbon dioxide gas indoors and outdoors. Consequently, it was found that when the flow rate of carbon dioxide gas is adjusted to make the biomass productivity of filament type Nostoc maximum,the inlet and outlet concentrations of carbon dioxide gas were 0.7% and 0.05% respectively with the absorption rate of more than 90%. From the standpoint of fixation and effective utilization of carbon dioxide gas, the above rate of removal is one of the important parameters and it will be necessary in future to compare the rates of removal of carbon dioxide gas among various types of bioreactors as a function of operating condition. 9 refs., 6 figs., 2 tabs.

In the experiment, a part or the whole of the fish meal protein is replaced by the meat meal (MM), meat and bone meal (MBM), corngluten meal (CGM), or dried silkworm pupa meal (SPM), and fries of the Japanese flounder are fed on the new diets for eight weeks. On a diet containing 60% or less of MM, no change is detected in the fish in terms of increase in weight, protein efficiency ratio, and blood components, indicating that 60% at the highest of fish meal may be replaced by MM. In the case of MBM, it can occupy approximately 20%. As for CGM, the proper substitution rate is approximately 40%. Essential amino acids that the new diets may lack are added for an approximately 10% improvement on the result. The SPM substitution works up to 40%, when, however, the blood components are degraded. The proper substitution rate is therefore placed at approximately 20%. 38 refs., 2 figs., 17 tabs.

    VENUS Project aims at constructing a deepsea geomagnetic and electric fields observation station to cover the Ryukyu Trench, Philippine Sea, and Mariana Trough, by the reuse of the Okinawa-Guam commercial marine communication cable now out of service. This report deals with a scenario for the development of a geomagnetic/electric observation system as a part of the planned long-term sea bottom observation effort and the installation of equipment therefor. The first stage consists of the towing of a frame mounted with the system equipment and a cable to connect to a data transmission relay and their placement at a specified location on the sea bottom. The cable is extended toward the relay and its leading end is allowed to land near the relay. Next, a manned submersible vessel is used to connect the cable end to the relay, the submersible vessel is next driven along the connection cable toward the system equipment for the determination of the position and orientation of the system equipment, and then electrodes are arrayed at an interval of 20m into an L-letter configuration. The system will be established in March, 1998, on the 4200m-deep continental slope of the Ryukyu Trench approximately 90km southeast of Okinawa. 2 figs., 1 tab.

    As part of the (district energy-saving visions for City of Iwai), the feasibility study is implemented for citizen community facilities which utilize waste heat discharged from factories in the city. More concretely, those items studied include a heated pool, other community facilities and botanical garden of tropical plants which utilize waste heat of exhaust gas cooling water heated to around 70 degrees C by a desulfurization unit at a pulp factory. Case 1 includes the citizen community facilities (e.g., heated pool and bath facilities), and Case 2 includes a green house botanical garden, involving studies on facility scales, requirements of heat and recycling water, hot water supply, air conditioning, bath systems, and heating systems for green houses. It is estimated that the citizen community facilities have an energy saving effect of 640kL/y as fuel oil, which corresponds to saving of around 29 million yen/y, and CO2 abatement effect of 471t/y as carbon, and that the green house botanical garden has an energy saving effect of 669kL/y as fuel oil, which corresponds to saving of around 30 million yen/y, and CO2 abatement effect of 492t/y as carbon.

    The research and development project is implemented for the chemical processes which utilize supercritical fluids, in order to establish the basic technologies for the environment-friendly chemical processes. For the solvolysis, the conditions under which plastics are hydrolyzed in supercritical water are investigated, and the basic data are obtained for the optimum conditions under which thermoplastic resins are hydrolyzed. The mechanisms involved in hydrolysis of polymers in supercritical water are elucidated to some extent. The environment-friendly process for synthesizing polycarbonate in supercritical carbon dioxide gas is investigated, and the continuous flow sheets are established for securing almost 100% conversion in the presence of an inexpensive catalyst. For the oxidation, the tests are conducted to burn low-grade coal in supercritical water, and the conditions under which it is burnt without releasing acid and toxic gases are found. For the hydrogenation, heavy fuel oil is treated in supercritical water to produce the lighter products. The conditions under which light oils and gases are produced are clarified, and the basic data are obtained for producing light gases from the resultant coke as the by-product. (NEDO)

    Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

    An environmentally friendly refuse energy utilizing business, for which RDF (refuse derived fuel) produced out of wastes discharged by industries belonging to a Fujieda city environmental protection council will provide the heat source, is proposed by the said council. The proposal is subjected to a study, a basic plan is drafted, and a decision is made on its profitability. In the study, surveys are conducted on the actualities of wastes and of demand for heat, and specifications are worked out relating to transportation and storage of RDF, production of steam by an RDF-fired boiler, routing of pipes for transmitting the steam to the industries in the district, facility costs, operating costs, etc. It is found that the amount of RDF produced out of the wastes discharged by the council member industries is so small that it can meet the demand of only one industry and that, even if more wastes are collected from a wider area, the increased amount will but meet the demand of two industries and a hot water pool. It is found that the system will be economically feasible, however, if the shortage of RDF-generated energy is covered by an oil-fired boiler and thereby impartiality is established in steam distribution and steam production unit price is reduced. In view of the intensification of control over dioxin, etc., the business will be gaining profit in 2002 and after. (NEDO)

    An apparatus is developed to establish a system which allows utilization of hydrogen safely and easily, and its applicability to a hydrogen system for domestic purposes is tested. The system converts solar energy by the photovoltaic cell unit into power, which is used to generate hydrogen by electrolysis of water at the hydrogen generator, stores hydrogen in a metal hydride , and sends stored hydrogen to the burner and fuel cell units. It is found that a hydrogen occluding alloy of LaNi4.8Al0.2 stores hydrogen to approximately 80% when cooled to 20 to 25degC, and releases it to 10% when heated to 40degC. The fuel cell uses a solid polymer as the electrolyte. The hydrogen gas burner is a catalytic combustion burner with a Pt catalyst carried by expanded Ni-Al alloy. The optimum distance between the burner and object to be heated is 22mm. High safety and fabrication simplicity are confirmed for use for domestic purposes. The system characteristics will be further investigated. 4 refs., 8 figs.

    This research and development project is aimed at treatment of sewage, industrial waste water and the like at lower cost for reutilization, while efficiently producing methane or the like by the systems annexed to the water treatment systems with high-concentration bio-reactor systems incorporating separation membranes. The waste water types studied to be treated by these systems include sewage discharged in large quantities and waste water containing oil/fat and protein (low-concentration waste water), and starch-, alcohol and paper/pulp-containing waste water, and excrements (medium-concentration waste water). The project has found the optimum systems, by adequately configuring the separation membrane modules, and combining dissolution of suspended solid with methane fermentation reactors for selective treatment of organic substances; improved efficiencies of removing organic substances and producing methane by fermentation, and realized reduction in quantities of discharged sludge; and thereby established the bases for the new waste water treatment techniques. The reactor systems developed for water treatment are those based on biological removal of nitrogen. They greatly reduce treatment time to produce treated water of high quality. For treatment of sludge, the techniques have been developed to convert sludge into oil. These results are well applicable to various areas, e.g., sewage treatment, and food and pulp industries.

    This paper introduces the circumstances and purpose of establishing the Basic Research Associate for Innovated Coal Utilization (BRAIN-C) Program started in October 1995, and the summary of the results therefrom in fiscal 1995. Although development of coal utilization technologies has been implemented over a number of years, there are many problems still requiring solutions. Early realization has been urged on diversification of coal utilization, acceleration of technological development and diversification of coal types. In order to achieve these goals, the necessity was recognized afresh on not only the hardwares, but also on basic technologies in terms of software which can identify properties of coals, systematize different reactions, and estimate reactions, fluidity and heat transmission of coals. Therefore, receiving a subsidy from the Agency of Natural Resources and Energy of the Ministry of International Trade and Industry, a research and development program to be implemented jointly by industries, administrative agencies and academic societies had been started with a five-year plan for the time being. With the activities for the program such as collecting 50 to 100 types of coals and supplying them to researchers, the program had been accelerated in fiscal 1995 on a large number of themes and results therefrom, including fundamental properties and thermo-chemical reactions. 2 figs., 4 tabs.

    This metal melting system is a process to efficiently melt and regenerate scraps of aluminum, copper and iron by utilizing high-temperature energy obtained from pulverized coal-oxygen combustion. The process is intended to utilize coal in place of petroleum for reduced fuel cost. Joint studies have been carried out as a subsidy operation of the Agency of Natural Resources and Energy with a schedule of six years starting fiscal 1992. Development tests are being performed using a 5-ton/ch pilot plant facility since fiscal 1995 after having gone through experiments using a 1-ton/ch bench scale furnace. This paper reports the results obtained to date. Using the pilot plant facility, fiscal 1995 has achieved the initial target values, such as thermal efficiency of 55% or higher, and yield of 96% or higher for non-ferrous metals and 94% or higher for iron. The melting behavior in the furnace has improved the thermal efficiency as a whole by retaining the conditions in the preheating step for an extended period of time. The thermal efficiency has been improved better than with the bench furnace as a result of upscaling effect. 9 figs., 3 tabs.

    This paper describes a possibility of geothermal utilization in Tomakomai City. The Tomakomai area has an extremely great amount of hot water existing in deep layers, leading to a consideration that it is very highly possible to develop the hot water. As seen from the underground structure and ground temperature gradient in the Tomakomai sedimentary basin, the development depth would be considerably great, being assumed to be about 2,000 meters. The acquisition amount per well is estimated 100 m{sup 3}/hour or more at 65 degrees C. Rise in petroleum price in the future is an unavoidable fate, hence geothermal water utilization has a fully bright future. The water has relatively low temperature, and is effective for use in room heating, hot water supply, and agricultural and livestock industries. It is worth considering utilization as a local energy system. It has also large secondary effects. According to the latest trial calculation, the unit price for hot water for room heating and hot water supply would be 10 to 20 yen per 1,000 kilo-calories. If the same amount of hot water should be supplied from a boiler, fossil fuel of 20,470 kl/year would be required. If converted by using a kerosene price of 75 yen per liter, the cost would be 1.3 billion 35 million yen, comparatively higher than the geothermal water utilization. (NEDO)

    Coal ash from the fluidized bed boiler is evaluated for its properties as is, as solidified or granulated, and as the roadbed material. The coal ash tested in the experiment is a mixture of ash from the fluidized bed boiler bottom, ash from the cyclone separator, and ash from the bag filter. In the manufacture of solid or granulated bodies, coal ashes are kneaded in water whose amount puts the mixture near the plasticization limit, are pressed in a low-pressure press and made into solid bodies by a 15-hour curing in 60degC saturated steam, and the solid bodies are crushed into solid granules. A content release test is conducted about the release of dangerous substances, and road paving experiments are conducted to learn the workability and serviceability of the granulated material as a road paving material. A study of the experimental results discloses what is mentioned below. Coal ash containing 10-20vol% of CaO and 15vol% or less of unburnt carbon turns into a high-strength solid after curing in saturated steam whose temperature is not higher than 60degC. The granulated solid satisfies the standards that an upper subbase material is expected to satisfy. It also meets the environmental standards in a release content test for soil set forth by Environment Agency notification No.46. 8 refs., 8 figs., 4 tabs.

    Discussions are given on treatment methods that can utilize scallop cultivation wastes effectively. Tests to incinerate and convert the main scallop shell content, calcium carbonate, into calcium oxide (CaO) discovered optimal incinerating conditions of a temperature at 750[degree]C and a duration for 30 minutes, and 700[degree]C and one hour. CaO content in burnt shells was so high that they could be used as a raw material for quick lime. In the incineration and conversion tests on wastes from shell processing factories, the result of X-ray diffraction in chemically combined conditions of inorganics before and after the incineration revealed that the main component Ca existed as CaCO3, which may be converted into CaO when incinerated. The result also showed that the second component, Mg, existed as MgO after the incineration. From the above results, incinerating the wastes from shell processing factories at 750[degree]C would be capable of incinerating organic components completely and reducing their weights. Because the inorganic residues have high CaO content, they could be utilized effectively as a quick lime raw material. Although shells to be incinerated have low salt content because of having been boiled, salt content in scallop processing factory wastes will require discussions on possibilities of its corroding an incineration furnace. 3 figs., 7 tabs.

A model of the cold accumulated heat system of the type which has a high possibility of the introduction was built to study a possibility of the realization. Types of the model system were selected assuming the utilization of cold heat energy of snow in Sapporo, a typical large city in the cold heavy-snow area. Studies were made on each model of urban type commercial facilities, urban type offices, suburban type shopping center, and suburban type hospitals. For each model, more than one systems were studied according to types and forms of the storage tank, and heat recovery methods. As a result, it was found that cold heat energy of snow can be utilized almost effectively by making an appropriate study of the energy balance like the possible supply of cold heat exceeded the demand in two models of an urban type office building and an suburban type hospital. Further, operating expenses of typical models were roughly calculated. 51 figs., 20 figs.

    An intercellular transport technology (artificial manipulation of an intracellular protein transport system in eucaryotes) is studied for the accumulation of cytotoxic proteins, whose expression has so far been difficult, and activated proteins, which have avoided decomposition, in appropriate intracellular minute organs. The aim is to construct a system to allow foreign proteins high in productivity and quality to express themselves for production in eucaryotes. Basic surveys were conducted of the intracellular biological functions of single-membrane organelles (endoplasmic reticulum, peroxisome, vacuole/lysosome, and Golgi body), the molecular mechanism of protein transport to each organelle, and protein activation and quality control, and element technologies were extracted. For the development of novel pharmaceuticals making use of the intracellular protein transport technology, an activated protein production system was built and a search was made for transport activity impeding substances. Research tasks relative to the development of the new technologies were isolated, such as the visualization of intercellular transport. A survey was made of the market for pharmaceuticals, cosmetics, enzymes, and visualizing equipment (fluorescence microscope provided with new functions), etc. (NEDO)

    A large quantity of waste sea water, exhausted after having been used as cooling water in the thermal and unclear power stations, is higher by about 7 centigrade in temperature than that when taken in. Its utilization to the marine cultivation to increase product was explained in present status and points of problem. Among aquatic animals to like high temperature, those, valuavle from the viewpoint of fishery, are bred in different places. Upon breeding spawn to fry young fish, there are two methods of using it, ie., as species to be cultivated or let go in the water flow, and for the production of edible fish, high in price, such as sea bream, yellowtail and lobster. In any case, hot exhaust water gives effect of having fish quickly grow, and stimulating spawn and fry young fish in sexual ripeness. For example, ear shell and prawn are 5 to 6 times in elongation of shell length and 9 times even in weight, respectively, as large as those in case of natural sea water. While there are problems in costing required for pumping hot exhaust water up in the cultivation on land, and temperature adjustment in summer and winter, and water quality control in the crawl cultivation at the water takeout, which must be going to be solved for the commercialization and industrialization. 10 figs., 1 tab.

    Research was made on solar heat power generation following last fiscal year, as a part of solar energy utilization technologies. In this fiscal year, in particular, research was made on the following: selection of suitable sites for solar heat power plants in Japan, estimation of expected power supply, positioning of a solar heat power system among future power systems, operation policy of solar heat power systems, survey on suitable sites for the 1,000kW pilot power plant, operation characteristics of the small test plant, design of the 1,000kW pilot power plant, test methods and facilities for every element equipment of solar heat power systems, an environmental test method for mostly solar collectors, and the profitability of solar heat power systems. Optimum operation temperature levels were nearly 350 degrees C for distributed systems and nearly 400 degrees C for centralized ones. The distributed system is profitable in a unit capacity range less than 5-10MWe, while the centralized system is profitable in a range over 10MWe. Under some assumptions, the power cost of solar heat power systems was estimated to be 20-30yen/kWH. (NEDO)

    Polders have no basin of their own, and the supply of irrigation water in polders is always short and unstable. The irrigation water system is so structured that the conflicting objects of both the insurance of irrigation water and drainage of rainwater can be achieved. Quoting an example at the surrounding area of the Kojima Bay in the southern area of Okayaja Prefecture where inning (land reclamation by drainage) has been practiced for a long time, problems in drainage improvement required for better use of low-lying flat lands are discussed. There are complicate relations among the safety against flood, rainwater drainage capability, stock capacity, and critical leveling time, therefore, the basic operation which must be performed at first in making a drainage plan is to determine the basic framework of the plan taking those relations into consideration. In low-lying flat lands, safety of the total area against flood has been established basing on the stock capacity of the paddy fields, and it is important to secure paddy field areas to a certain extent. 8 refs., 7 figs., 1 tab.

    The current most important solar energy utilization fields are solar energy power generation (solar heat and photovoltaic power generation), and solar heat cooling and heating. A solar heat power system collects or stores solar thermal energy as energy source of power systems, and converts it to electric power through heat exchange systems. To establish such system, not only R and D on a collector, absorption capsule, storage unit and heat transfer unit, but also complete study on an optimum system configuration and environmental impact are necessary. A photovoltaic power system converts solar energy to electric power directly by photoelectric conversion device such solar cell. Except specific local uses, drastic cost reduction and improvement of a conversion efficiency (at present 12-15%) and life (several years) are necessary for solar cells. Although a lot of solar heat cooling and heating systems is in practical use in Japan, for its further diffusion an important research task is development of heat collector excellent in efficiency, cost, life and maintainability.

    Wastewater reuse can be considered as a type of water resource development which is expected to improve the aquatic environment, as well as the stability and reliability of municipal water supply systems. To this extent, wastewater reuse has been taken into account in the planning of water supply systems in several Japanese cities. However, to date the effect of wastewater reuse on water supply system stabilization has not been discussed quantitatively, and the relation between waster water reuse rate and water supply system stability has not been analyzed. In this study, a stochastic model has been presented to evaluate the stability of water supply systems with optimal wastewater reuse rate. Some theoretical analyses and numerical studies were performed, and all of the results have shown that the model is reliable for not only basic studies on water supply system stability, but also for practical use as well. 5 refs., 5 figs., 3 tabs.

    The geographical position or environment is set on the assumption that the natural energy of a detached house is used in a hybrid state. Moreover, the energy consumption of the house and the natural energy supply obtained from the geographical position were compared and investigated. As a result, the energy consumption is 10,617 kWh, and the energy supply is 8,236 kWh. About 78% of the whole consumption can be theoretically made from natural energy. The energy supply is calculated on the low side during prediction. Therefore, an increase in the energy supply is expected by installing a solar collector based on solar energy, expanding the solar panel area, and increasing the number of wind mills. However, this energy is partially lost via an inverter while it is supplied to the general domestic equipment. At the six main points in Tokyo and its districts, the adaptability of natural energy used based on the regional characteristics is investigated presently and the installation of a system is examined. 13 refs., 2 figs., 6 tabs.

    Studies have been made about a heat accumulation tank type cooling system making use of radiation cooling that is a kind of natural energy. The daily operating cycle of the cooling system is described below. A heat pump air conditioner performs cooling during the daytime and the exhaust heat is stored in a latent heat accumulation tank; the heat is then used for the bath and tapwater in the evening; at night radiation cooling is utilized to remove the heat remnant in the tank for the solidification of the phase change material (PCM); the solidified PCM serves as the cold heat source for the heat pump air conditioner to perform cooling. The new system decelerates urban area warming because it emits the cooler-generated waste heat not into the atmosphere but into space taking advantage of radiation cooling. Again, the cooler-generated waste heat may be utilized for energy saving and power levelling. For the examination of nighttime radiation cooling characteristics, CaCl2-5H2O and Na2HPO4-12H2O were tested as the PCM. Water was used as the heating medium. In the case of a PCM high in latent heat capacity, some work has to be done for insuring sufficient heat exchange for it by, for instance, rendering the flow rate low. The coefficient of performance of the system discussed here is three times higher than that of the air-cooled type heat pump system. 8 refs., 5 figs., 4 tabs.

    A permanent borehole energy storage system utilizing solar energy and waste heat from coolers is simulated, to be used as an air conditioning system for super-tall buildings. A 100m-long pipe is buried vertically into the ground, and a heat medium is caused to circulate in the pipe for the exchange of heat with the soil. Thirty borehole units are used, each measuring 9m{times}9m (with the pipe pitch being 3m). Solar cells occupying half of the wall surface facing south and solar collectors installed on the roof supply electric power and heat for cooling and warming. Heat in the ground is transferred mainly by conduction but also is carried by water and gas in movement. So, an analysis is carried out using an equation in which heat and water move at the same time. Because waste heat from cooling and warming systems is accumulated in the ground and none is discharged into the air, big cities will be protected from warming (from developing heat islands). As compared with the conventional boiler-aided air conditioning system, a hybrid borehole system incorporating solar collectors and solar cells will bring about an 80% reduction in CO2 emission and annual energy consumption. 7 refs., 3 figs., 4 tabs.

    Performance of a solar heating system with a hydrothermal source heat pump was evaluated and compared with that of a direct solar heating system. The sun-dependency rates ({Sigma}D and {Sigma}H)of the direct system and heat pump (HP)-provided system were expressed as a function of the rate ({alpha}) of the auxiliary heat against the collected heat and as a function of the performance coefficient and {alpha}, respectively. When the sun-dependency rates are compared, it is found that the HP-provided system is the more advantageous when {Sigma}H/{Sigma}D>1. The relationship between the {alpha}`s of the two systems was clarified and computation was performed to compare the sun-dependency rates on condition that the two are equal in the heat collecting area. Although the sun-dependence rate cannot be elevated to 100% in the HP-provided system, it achieves a sun-dependency rate higher than that of the direct system even when the heat collecting area is small. In cases where the building is economically limited, for instance, with respect to the area for solar collector installation, it is advantageous to employ the HP-provided system. 5 figs., 1 tab.

    Survey was made on application technologies of next- generation high-density energy beams. For real application of laser power, application to not exciting source of YAG crystal but machining directly is highly efficient. For generation of semiconductor laser high-power coherent beam, phase synchronization and summing are large technological walls. Short pulse, high intensity and high repeatability are also important. Since ultra-short pulse laser ends before heat transfer to the periphery, it is suitable for precise machining, in particular, ultra-fine machining. To use beam sources as tool for production process, development of transmission, focusing and control technologies, and optical fiber and device is indispensable. Applicable fields are as follows: machining (more than pico seconds), surface modification (modification and functionalization of tribo- materials and biocompatible materials), complex machining, fabrication of quantum functional structured materials (thin film, ultra-fine particle), agriculture, ultra-precise measurement, non-destructive measurement, and coherent chemistry in chemical and environment fields.

    An artificial mutation/selection system was constructed in a laboratory based on molecular-level findings collected about the biological evolution mechanism, and biotechnology was studied for creating excellent biological functions. In the study of novel mutation generating technologies, selection is performed after the formation of numerous chimera enzymes by a family shuffling process using resistance to heat as the index. Then, a hybrid enzyme with its resistance to heat more than 10 times higher than that of the parent enzyme was obtained. In the study of establishing coordination between genotype and phenotype, a highly sensitive bacterial coordination technology was developed, and a highly sensitive detection method was constructed using a flow cytometer. As for technologies of highly efficient selection, a research was conducted about the selection of catalytic antibodies equipped with protease and esterase activity.

    Abrupt and steep climate changes of the millennial scale as represented by the Dansgaard-Oeschger cycle (D-O cycle) and the behavior of the global surface layer system in their wake are outlined. The D-DO cycle is the abrupt and steep climate changes that are recorded in the Greenland continental ice sheet, and is grasped most typically as changes in the oxygen isotopic ratio in the ice. Studies reveal that the D-O cycle is a global episode that accompanied interaction between various subsystems constituting the global surface layer system. It is believed that in the D-O cycle there were changes not only in temperature but also in aridity/moisture and in the sea level, and probabilities are high that there was a great local variation in the way the changes took effect. The possibility has now become lower that the D-O cycle occurred in the interglacial epoch in the high latitude belt in the northern hemisphere, yet it remains likely that the climate changes driving the D-O cycle continued in the low latitude belt. 57 refs., 8 figs.

    It is necessary in the field of post-genoms to know statistical correlation between DNA orientation information and clinical data, which helped growth of DNA probe arrays (DNA chips). However, it is difficult in patent point of view to develop chips in Japan. On the other hand, a movement has begun to use beads fixed with DNA probes in place of DNA chips demarcated on the surface of solids. This is a method to investigate hybridized DNA by means of fluorescent detection, in which each bead retaining the DNA probes is colored to make identification of the retained probes possible, and hybridizing reaction is performed in aqueous solution. Hitachi has developed a DNA measuring technology using bead arrays. The bead array has probe fixing beads of about 100 {mu} m laid sequentially inside a capillary, wherein the array can be used to inspect a large number of genes. Thus, this method can be a DNA measuring technology which is inexpensive, and high in reproducibility. These features lead to a belief that the technology is suitable for gene inspection devices used in the process of medicine development and at the clinical sites. (NEDO)

    Steel structures in sea water and surface of hulls are deposited with such marine organisms as microorganisms, algae and shellfish. The deposition causes a large problem such as occurrence of abnormal local corrosion in the structures, and increase in cruising resistance in ocean vessels. The present study has introduced a simplified equation of estimation for current and potential distribution in parts coated with an electrically conductive film, and verified its reasonability by an experiment. The equation of estimation was introduced by following a model of current flow in the electrically conductive coating. The experiment has the conductive coating applied to the interior of a concrete water tank with a length of 10.8 m, a width of 5 m and a depth of 3 m to measure potential at different locations. The conductive coating was energized from copper foils attached on each applied face, whereas the current was applied to two faces between the conductive films as a pair among the four coating applied faces to measure potential in each location. A simulated calculation revealed that the potential range in the depth direction is made smaller if specific resistance of the conductive film is decreased, and made greater if increased. Effectiveness of the equation of estimation was verified by an experiment. This method has provided a prospect of achieving optimization of the specification for application of the conductive film. 2 refs., 7 figs.

    The whole amount of hydrogen consumption for chemical industries all over the world is estimated to be 249.7 billion Nm{sup 3} in 1974, while 367.2 billion Nm{sup 3} in 1980 roughly under a bold assumption, based on 3 current big consumption fields of ammonia production, methanol production and petroleum refining, and some promising fields in the future such as reduced iron and synthetic protein. Consumption ratios for every field are probably 54.9% in ammonia production, 30% in petroleum refining, 9.5% in methanol production and 5.6% in others in 1974, and nearly similar in 1980. However, although there are various troubles, if a large amount of methanol is used as fuel in the future, and its production plan is promoted to satisfy the demand of methanol fuel, hydrogen consumption for methanol production will increase drastically. In the future, if the production process of hydrogen as secondary fuel is established, such hydrogen also will be used for various chemical industries naturally. Research was thus made on use of oxygen as byproduct inevitably. (NEDO)

    Research and development program is conducted for the elementary techniques as part of the eco-energy urban project of New Sunshine Project. Described herein are the FY 1999 results for the (techniques for transportation and storage of energy). The R and D on methanol energy systems involves the R and D on decomposition and synthesis catalyst of methanol and methyl formate for the waste heat sources of relatively low temperature. The R and D on high-efficiency techniques using hydrogen-occluding alloys involves development of heat exchangers of low sensible heat ratio, fabrication of double-effect type MH heat pump cycle devices, and demonstration tests for the system operation. It is found that the heat output of the hydrogen-occluding alloy for high temperature use is 0.18kW/kg at 90 degrees C, and that the alloy can be massively produced. A thermal utilization efficiency COP of 0.68 is obtained for the double-effect type MH heat pump cycles.

    As for the collection of sensible heat, 1/3 of blast-furnace slag is treated to the purpose at the Teesside Technology Centre, Britain, but none is collected in the latter half of tapping in case there is so much slag that cooling cannot be done in time. In the case of a large blast furnace, some measures have to be contrived because molten iron comes out of the furnace intermittently. In Germany, the heat collection rate is as low as 3%, with no effort made at heat collection. In North America, desire to develop such a technology is not strong. A visit was made to the Institute of Ocean Sciences, Canada, in relation to the concept of using steel slag as a eutrophic source for marine photo-plankton. A large-scale long-term test is under way for examining the relationship between global warming and ocean current circulation. There are possibilities that Japan will enter into the project for a joint study, for example, of heavy metal elution from slag though the test fails to name slag as the direct object of study. Not only for Canada but also for any other country who faces the sea, it may be a meaningful national policy to inject some active ingredients into the sea for an increase in living marine resources. Greece is engaged in the ocean dumping of nickel slag on an experimental basis but, in view of the purpose of the experiment, Japan will not be a participant in the project. (NEDO)

    For the purpose of working out a comprehensive master plan for application of the coal utilization system, the paper surveyed and studied the coal utilization system in terms of environmental measures and efficiency improvement in the utilization of coal. As a result of the discussion with NEDO and the National Planning Committee of China, Liaoning Province (the whole China) and Shenyang City were selected as a model area and a model city for the survey and study. As energy conservation measures taken in the former, desirable are intensifying/capacity-increase of boilers, kilns, etc. and adoption of new-type/high-efficient equipment. Also expected are reinforcement of combustion control and improvement of efficiency by using coal preparation, industrial use coal briquette, etc. Measures taken in the latter are the same as those taken in the whole China. As SOx reduction measures for Liaoning Province, desirable is installation of dry-type desulfurization equipment and simple desulfurization equipment. As dust prevention measures for it, desirable is installation of electrostatic precipitators or high-functional bag filters. SOx reduction measures for Shenyang City are the same as those taken in the whole China. SOx can be reduced by using coal-prepared low-sulfur coal and industrial use coal briquette added with desulfurizing agent. 88 figs., 163 tabs.

    This paper describes comprehensive discussion on hydrogen utilizing subsystems. Hydrogen combustion is characterized by how low the ignition energy is, and how fast the flame propagates. In addition, flame stability is high also in diffusion combustion. However, the diffusion combustion produces a great amount of NOx, the amount varying depending on the degree of air pre-mixture. Since it causes reverse ignition very easily in the pre-mixture degree corresponding to low NOx zone, development of a burner with drastically new mechanism is demanded. In hydrogen fuel cells, the ratio of hydrogen fuel cost accounting for in the power generation cost is very high. As an automobile fuel, very much leaner combustion is possible than in conventional internal combustion engines, and ignition energy is small. However, such abnormal combustion as reverse ignition and early ignition may occur, and their prevention is an important assignment. Issues in aircraft engines are verification of safety, and cost of liquefied hydrogen. Steam turbines have reached their limit already, but gas turbines are expected of exciting efficiency improvement. This paper describes prospects on chemical utilization of hydrogen in the existing fields and new fields. (NEDO)

    The paper surveyed the present situation and future trend of economy, energy supply/demand, coal production/distribution/utilization and the environmental effects in Thailand. The survey on the coal utilization and its environmental effects was partially requested of the environmental research institute in Thailand. The amount of coal utilization in Thailand rapidly increased to nearly four times as large as that ten years ago mainly in terms of domestic lignite under the government`s policy on expansion of the domestic energy use. However, most of this domestic lignite is low-grade coal with low calories and high sulfur content, and the use of it was rapidly increased mostly in power generation sector without no adequate environmental measures taken. This caused an environmental problem on air pollution due to sulfur oxides at Mae Moh power plant in the north several years ago, and the damages to the regional residents, etc. were given much publicity by journalism and developed the social problem. Accordingly, Thai people are now critical of the coal resource exploration and the coal use expansion. Under the circumstances, the Ministry of Industry and the energy related ministries/offices are obliged to review their development/promotion plans. 84 figs., 99 tabs.

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

    Taking the area of the clean coal technology (CCT) effective for energy conservation and environment preservation as the object, a feasibility survey has been performed on executing a model project in India. About 70% of the total power generation capacity in India depends upon coals existing in abundance inside the country. Since the local coals are high in ash, low in sulfur, and low in calorie, the environmental problem related to thermal power plants is the disposition of fly ash. The Central Electricity Authority of India expects solving this problem by CCT introduction. It also expects increase in combustion efficiency by using ultra-critical boilers. The Indian cement industry often uses in-house electric power generation facilities because of high electric power cost, wherein the produced coal ash is used as a cement raw material. The matter of the strongest interest is the introduction of a high-efficiency combustion system that depends on low-grade coals. Among the CCTs, strong interest was shown in the fluidized bed cement kiln and the circulating fluidized bed boiler. The iron and steel industry has expectations toward effective coal washing technologies and coke manufacturing technologies. (NEDO)

    The paper investigated and studied the present situation and future trend of coal utilization and distribution in Thailand, and the present situation of environmental effects and the measures taken for environmental protection. Around 2010, coal will probably be produced only at EGAT`s Mae Moh (MM) coal mine. Demand for overseas coal is expected to be 40-50 million tons in 2011, and preparation of the coal center becomes a subject. For general industry use coal, pretreatment such as coal preparation, coal blending and briquetting is needed, considering coal quality, usage, transport distance and environmental effects. Brown coal of MM coal mine is a lignite with high sulfur, high ash content and low heating value. Wide spread of its use can be expected if upgrading is possible such as desulfurization, deashing, increasing heating value. In the electric power generation field, the absorber was installed at the existing boiler of the mine-mouth generating plant to conduct a verification test on high grade desulfurization of ultra-high sulfur lignite. In the industry field, the circulating fluidized bed boiler was adopted. In the residential/commercial field, introduction of briquette was proposed. 80 refs., 84 tabs.

Sugar chain marking and refining techniques and various responding mechanisms on the solid surface were elucidated, which enabled structure analyses using sugar chain recognition molecules such as lectins and antibodies. A database on interactions between sugar chains and sugar chain recognition molecules was constructed using the said findings. An analyzing program was also formulated tentatively. This paper also covers general surveys and studies on technologies of producing and utilizing glycoconjugates. (NEDO)

    This paper reports on the present situation of the chemical use of hydrogen and oxygen, and the short-term, medium-term, and long-term forecast. The main usage of hydrogen is ammonia synthesis, petroleum refining, and methanol synthesis. In the usage of these three, there are factors of structural changes now and in future, and it is extremely difficult to predict the amount in a short term up to around 1980. In a medium term prediction, from the result of predicting the demand of ammonia, methanol and hydrodesulfurization, the total 1985 hydrogen demand is estimated at approximately 60 billion Nm{sup 3}, and approximately 67 billion Nm{sup 3} as the gross hydrogen demand. Further, judging from that synthetic protein, fuel use methanol, and reduced iron are estimated to reach a certain production size in and after 1985, new demand for hydrogen is expected to be approximately 100 billion Nm{sup 3} mostly including fuel use methanol. In a long term prediction, it is extremely hard to predict the demand because of various factors existing in Japan and abroad. As predicted in a medium term, the amount of chemical use of hydrogen is expected to increase more and more, even if calculating it only in the field of ammonia synthesis, petroleum refining, and methanol synthesis.

    The utilization in Japan and abroad is discussed of desalination methods using evaporation, reverse osmosis (RO) membranes, and electrodialysis membranes, out of various desalination techniques for seawater and others containing more salt. A new seawater desalination plant built in Okinawa, Japan, is outlined, and the future trend of Japan`s efforts for desalination is predicted. The said plant in Okinawa is the largest ever built in this country, and occupies 4th or 5th place in terms of capacity among similar facilities across the world. It was completed in April, 1997, and produces pure water at a rate of 40,000m{sup 3}/day. This plant, operating on RO, comprises eight RO membrane units each capable of 5131{sup 3}/day. The membranes are of the spiral type, consisting of Toray`s crosslinked aramid-base composite membranes and Nitto Denko`s membranes composed totally of crosslinked aromatic polyamide. The greatest of the pending tasks is to reduce the desalination cost. As for the operating cost of the desalination facility at the current stage, it costs 120-130 yen/m{sup 3} on the 40,000m{sup 3}/day scale, and the power cost occupies approximately 60% of the total operating cost. It is concluded that the consumption of electric power and chemicals per pure water produced have to be reduced. 8 refs., 5 figs., 5 tabs.

    This paper describes the discussion report for fiscal 1998 on the CMG (coal methane gas) recovery and utilization project to be implemented from fiscal 1998 through fiscal 2002 at Tiefa Mining Bureau of Liaoning Province in China. The Daixing mine was selected as the survey object. The introduced technologies and facilities include test drilling for degassing (medium measure horizontal degassing of 300-m class), induction from degassing holes, fly ash sealing, sealed gas degassing, surveillance and control technologies and facilities. The recovered gas is to be supplied to the cities of Tiefa and Tieling as town gas, for which compressed gas feeding and controlling technologies and facilities will be introduced. This paper lists the gush-out quantity (1,000 Nm{sup 3}), the recovery quantity (1,000 Nm{sup 3}), the recovered gas concentration (%), the utilization quantity (1,000 Nm{sup 3}), and the utilization rate (%). The figures for the respective items before and after the implementation are 128366, 32949, 44.5, 7000, 5, 123500, 43890, 49.1, 39826, and 32. The quantity of gas gushing out at facings decreases in association with increase in the recovered gas quantity, whereas the gas concentration at facings in the Daixing mine in 2003 is estimated to decrease to 0.1%, contributing to safe mining operation. The test drilling for medium measure horizontal degassing expands the degassing assured scope per one test drilling seat, and can reduce the total test drilling length and construction amount.

    Researches were conducted for the goal of proposing a totally new process enhanced in efficiency and energy saving, and capable of CO2 separation. In fiscal 1997, hydrocarbon materials were reformed by oxygen separated within a system allowing fuel cells to generate power efficiently, when all the emitted CO2 was separated and recovered within the system. Furthermore, cold heat was utilized for the acquisition of liquefied CO2 gas products. A part of oxygen separated at the fuel cell cathode was recycled into the combustion section external to the tubular reaction reformer, and CO2 was separated by mere cooling from the combustion products for the simultaneous production of by-products such as high-purity nitrogen gas and liquefied CO2 for a great improvement in economy. In fiscal 1998, the system was improved. Proposed then was a new system in which an oxygen partial oxidation type reformer assumed the nuclear role, separating all the oxygen at the cathode, reusing part thereof for oxygen enrichment, and feeding the rest thereof into the reformer. The design realized the recycling of the whole of the products of the two cell electrodes into the reformer for the maximum reuse of the products of the hydrogen/oxygen separation function. (NEDO)

    An energy saving survey is conducted for the above named plant under a project expected to be linked to the clean development mechanism of COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change). Supply/demand balance is poor at various utilities in this refinery, with surplus steam in summer and with hydrogen rich surplus off gas (flare combustion, discharge into the air) from the respective devices causing numerous problems about energy efficiency. Under the project, hydrogen will be recovered from the refinery off gas for utilization, systems related to fuel, steam, and power will be improved, and a surplus gas fired turbine power generating facility will be installed. Power generation of 29MW is feasible, which elevates the percentage of private power generation to the total demand for power from 25% to 71%. The purchase of power from external coal fired power stations will decrease greatly, contributing to energy saving. A yearly amount of 136-thousand tons of CO2 will be reduced thanks to the hydrogen recovery system and the gas turbine power generating facility to be newly installed. The Chinese party, much interested in the project, intends to be a participant as a joint implementer. The Japanese party has received a request for technological and financial assistance. (NEDO)

    Based on the results of the survey of the potential quantity supplied of overseas resource which was made from FY 1981 to FY 1983, the paper predicted the world methanol supply plan, changes in the oil situation, economical efficiency of methanol and the competitive power with petroleum products, etc., and studied the time of potential supply, areas of potential supply and supply potential of power generation use methanol during the period toward 2000. In case the comparatively low crude oil price is predicted due to the energy supply/demand (Scenario A), the supply potential of power generation use methanol in four projects on methanol production taken up as trial calculation example is considered very low. Even in case the comparatively high crude oil price is predicted (Scenario C), it is in 1989 that the methanol market price becomes equivalent in heat quantity to the crude oil price. It is difficult to expect the potential before 1989. In case of the intermediate case between Scenario A and Scenario C (Scenario B), it is in 1993 that the methanol price becomes equivalent in heat quantity to the crude oil price. It is difficult to expect the potential before 1993. (NEDO)

    With the purpose of developing high strength and high-anticorrosive aluminum-based material through microstructure control, R and D was conducted, with fiscal 2000 results compiled. In the research of grain refinement mechanism, molten metal rolled stock was experimentally produced in which Mg content was varied 0-2.5 mass % with Al-2.5 mass % Mn as its base. As a result, a microstructure with an average grain size of about 3 {mu}m was obtained by processing the alloy through homogenization at 550 degrees C, cold rolling by 91% and the final treatment at 350 degrees C without Mg addition. Addition of Mg increased square grain boundaries in the microstructure, raising proof stress to about 180 MPa in Al-2.5%Mn-2.5%Mg alloy. In the research of development of the machining process, a rapid heating process was performed on a typical aluminum alloy, with the effect examined, by an alloy system or a plate thickness, on the electric power used and on the temperature reached. A rapidly heated aluminum alloy plate turned to have a microstructure with equi-axed grains of a uniform size, compared with a salt bath processed material heated at the same temperature. (NEDO)

    Field research was made for oil saving in Thailand. To promote energy saving in a textile industry as main export industry, its motivation for production stuff is essential in business improvement. Proposal for work improvement, supply system of bonuses, and small-group activity are effective. Management of an energy consumption rate is essential in business management. Use of efficient waste water treatment equipment is also one of the issues. In food factories, various scopes for improvement are still found by mass/heat balance analysis in production process. As an example, a large amount of water is consumed in vain for washing raw rice in a rice powder factory, and separation of SS precipitate from waste water should be improved. Because of lagoon treatment, an effluent standard is not achieved in spite of consumption of wasteful aeration power. This treatment is reasonable because of its scale and site, although the standard can be achieved by activated sludge method. Reconsideration of the standard is also necessary based on a local total BOD load capacity. The profitability of a methane fermentation method should be examined. 72 figs., 95 tabs.

    An investigational study was made of potentiality of a new system for methanol production by using abundant hydraulic power energy overseas and by combining water electrolysis and coal gasification technology, and the FY 1992 results were summarized. In this fiscal year, survey was made of the potential water power and coal in Malaysia, Canada and Brazil, and case study was also made. As a result of the study, the cost of methanol was 7.1 yen/10{sup 3}kcal in case of Malaysia, 8.6 yen/10{sup 3}kcal in case of Canada and 8.9 yen/10{sup 3}kcal in case of Brazil. It was found out that the cost was economically less advantageous as compared with the present methanol price of 3.0-5.5 yen/10{sup 3}kcal. In a comparison between the existing coal/oil/LNG thermal power generation and this system from viewpoints of the energy balance/CO2 emission amount, the energy balance of this system is worse than those of the above-mentioned power generation when adding the coal thrown, but the CO2 emission amount of the system was less than those of coal/oil thermal power generation. In conclusion, this system seems to be an effective means in the light of the promotion of development of the undeveloped hydraulic power, effective utilization of renewable energy and global environmental preservation.

    On-site researches are conducted to study the possibility of a model business using energy-saving and environment preservation technologies of Japan and Indonesia. At textile plants, the management of heat and water in the dyeing and finishing processes is found inadequate, with great quantities of heat left uncared-for in medium- and low-temperature wastewater. An energy-saving proposition is submitted in which solar energy and absorption-type refrigerators are combined. Instrumentation and management also require improvement. At nitrogenous and phosphatic fertilizer plants, the energy consumption rate is found aggravated by degradation of facilities, and continued research and further analysis are necessary before working out energy-saving policies for them. At urea fertilizer plants, though it is not easy to modernize the manufacturing processes, energy-saving and environment preserving efforts are under way within the bounds of capability. Their energy consumption rate is high because of frequent shut-downs. It is necessary to detect an anomaly at its early stage and to introduce backup systems for the elimination of erroneous operations. Operating conditions need to be analyzed for validity. At melamine manufacturing plants, process drainage is allowed into the river without any treatment contaminating the water with products of melamine hydrolysis. Short-term and long-term solutions are suggested. (NEDO)

    For global scale measures to be taken for environmental protection, it becomes more and more important in the future to positively transfer and spread energy conservation technologies of Japan to overseas countries. Especially, it is effective for both economic growth in the Asian region and global environmental protection to transfer technologies which the oil refining industry has been developing and accumulating. Energy conservation in the oil refining industry means the energy conservation by strengthening the operational control at the first and second oil crises in the first stage, the energy conservation in the second stage which was accompanied by small and medium scale plant/equipment investments during several years after the first stage, and the energy conservation in the third stage which was accompanied by large scale investments from the first half of the 1980s to the present, resulting in improvement of 40% over before the first oil crisis. As to environmental protection measures, measures to reduce waste from oil refinery against air pollution and water pollution were prepared by the first half of the 1970s, and technologies were established of waste water treatment, flue gas desulfurization and denitrification. A lot of facilities for improvement of product quality and for low pollution were installed. In addition to environmental technologies, also in other industries, there were seen the heightening of thermal efficiency of kiln and thermal efficiency of cooling technique of clinker cooler in the cement industry and the improvement of productivity in the paper/pulp industry. 360 figs., 62 tabs.

    Research and development have been carried out with an objective to re-utilize waste cable covering materials as oil substituting energy. The research has been performed on behavior of chlorine and lead being substances that impede making the cable covering materials into fuel, development of a technology to remove chlorine, lead and copper, and pelletizing properties for fuel making. In the study of behavior of chlorine and lead, the following matters were made clear: dechlorination reaction completes within 30 minutes if pyrolysis temperature is higher than 300 degrees C; the more the amount of filler CaCO3 in test samples, the less the dechlorination amount; and secular deterioration does not affect the dechlorination amount. A technology has been developed successfully to remove the substances that hinder making the cover materials into fuel, achieving the target values of copper at 0.2% or less, lead at 0.3% or less, and chlorine at 5% or less. In developing the pelletizing technology that puts the cover materials into raw materials for blast furnaces, dechlorination rate of 90% was achieved by mixing coke/PVC at a ratio of 1/1 and dechlorinating it by using a rotary kiln. It was verified that the product is free of problems in particle size as the blast furnace raw material. (NEDO)

    This paper describes R and D on creation technique of novel advanced enzymes. In fiscal 1997, a novel mutagenesis technique was developed to obtain more kinds of mutational genes by shuffling between clonal genes as compared with the previous homogeneous recombination. A genotype- and phenotype-linking technology was developed by expressing random motifs (peptide as components of the active site of protein) on bacteria, and by developing a single-motif protein library. Study was made on a selection system for functional molecules of catalytic activities in a gene level, and a selection system for function of signal transduction. Analysis and evaluation study on vitro experimental technology can be efficiently promoted by recognizing the fitness landscape of target protein molecules. As a result, instead of the conventional method which needs several cycles of mutation and screening of 3-4 week/cycle, an efficient method possible to obtain multiple mutants was established.

    The R and D project is implemented for design, fabrication and installation of ocean-based artificial deep ocean water (DOW) upwelling devices which can take DOW at low cost in an ocean; experiments for enhancing productivity of ocean by adding DOW using mesocosms; and studying the biological effects of DOW for keeping freshness of marine products. DOW is successfully taken by the upwelling system from a depth of 800 m in a sea area 2,000 m or more in depth. The system has worked to perform its functions even when attacked by typhoons, which caused wave height of 10 m or more. For enhancing productivity of ocean, the culture experiments are conducted in a small-size, on-shore tank, and the mesocosm experiments in a harbor. The results indicate that addition of DOW increases the phytoplankton phase and its quantity. It is also observed that addition of iron ion further accelerates the fertilizing effect. The results of the experiments conducted in a harbor also indicate that DOW has the fertilizing effect, even in a very small quantity, increasing quantity of small zooplankton. No definite effect of DOW, liquid or ice, is observed for keeping freshness of sliced raw sea bream and bonito. (NEDO)

    The paper outlined the present situation of industrial waste all over Japan and the present situation of industrial waste of large urban areas where it is most difficult to secure places for the final disposal, and conducted an analysis on the present and future amount of final disposal waste. According to the literature from the Ministry of Health and Welfare, `research report on the discharge/treatment situation of the industrial waste` and `research results of administrative organizations for industrial waste,` the situation of final disposal from the past to the present was outlined and analyzed to study the future trend. Out of the administrative divisions of Japan, four divisions, which are all typically called large urban areas, were selected, and the situation of industrial waste in large urban areas was outlined and analyzed according to the questionnaire survey and the literature on industrial waste obtained from each administrative division. The survey by the Ministry of Health and Welfare indicated that the volume of the industrial waste discharged from the whole country amounted to approximately 400 million tons in fiscal 1992. However, helped by the improving recycling of waste construction materials, the amount of final disposal around 2000 is presumed to be less by 20% or so than that in 1992. 58 refs., 5 tabs.

    This paper is a generalized report in relation with the mine waste water treatment technology utilizing biotechnology, from among the promotion projects for research cooperation with China. Ferric iron (Fe{sup 3+}), which precipitates at low pH, is produced by utilizing bacteria which derives energy from oxidizing ferrous iron (Fe{sup 2+}) in the waste water, and the iron is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Joint researches and developments have been carried out on selection of optimal kinds of bacteria, cultivation of bacteria oxidizing iron at high efficiency, optimal removal system of heavy metals in mine waste water, and recovery of useful resources. Japanese engineers were sent to sites in China, Chinese researchers were received in Japan, and pilot plants were operated and studied. For the purpose of proliferating and enlightening the result of the project, a seminar was held in Beijing in February 1998. In order for the achievements derived up to fiscal 1998 to be used in diverse fields, fiscal 1999 will carry out follow-ups, including assistance, for the voluntary researches performed by China. The follow-ups will also include confirmation on the state of testing the iron oxidizing bacteria technology, technical guidance, and analyses and discussions on the data. (NEDO)

    Introduction of geothermal heat pump systems, which depend on temperature differential, is investigated for urban areas, which have large energy demands. Results of the surveys on the current situations of geothermal heat pump (GHP) systems indicate that they have already numbered 300,000 units in USA and totaled more than 50,000 units in Switzerland and Northern European countries, and that they are increasing at an annual rate of higher than 10%. The results also indicate that introduction of these systems are well feasible in Japan, which generally has better topographical conditions than American and European countries, and the GHP system with vertical ground heat exchanger is investigated for its topographical and environmental considerations. These systems could annually abate approximately 52 million tons of CO2 (4.3% decrease), if disseminated to all households. They are also expected to help control the heat island phenomenon, and reduce peak power consumption. The technological problems to be solved before these systems are massively disseminated including development of small scale drilling rigs and preparation of drilling manuals. System standardization and introduction of subsidy systems are also needed to massively disseminate these systems. (NEDO)

    The above-mentioned effort is to comply with the COP3 (Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change) joint implementation clause. At this coal field, mining facilities are growing superannuated and obsolescent in the prolonged business depression, causing frequent occurrence of disasters such as gas explosions. The coal mine gas collection rate at the Kuznetsk coal field is as low as 17%, with concern for safety discouraging sufficient collection. Even the small amount of the collected gas is, in the absence of gas utilizing facilities, totally discharged into the air. For the mitigation of global warming, for mining safety, and for the establishment of a foundation for business, it is desired that coal mine methane gas collection/utilization facilities and related technologies be introduced into the coal field. Gas purging from the pits is incomplete, which is attributed to the lack of equipment capable of excavating proper-diameter bores longer than 100m for longwall mining. Ventilation also needs improvement. The research is under way on the premise that highly reliable intermediate range (300m) boring equipment and gas management technologies will be available. Collection of gas of a 30-35% concentration level at a collection rate of 40% is the target. (NEDO)

    The paper clarified subjects on energy conservation in the transportation sector in Japan, and at the same time, studied measures to be introduced for effective use of energy. Recently, unit requirement of energy consumption per GNP has been increasing. One of the factors for the increase is the development of motorization arising from changes in life style and the increase in energy demand in the transportation sector in association with the changes. When considering global warming, the environmental problem, and medium- and long-term energy security, the more effective energy utilization by promoting energy conservation as well as the promotion of introducing clean petroleum substitution fuel are requested in the transportation sector where oil dependence is 98%. An analysis was made of energy demand in the transportation sector in Japan, and the result was internationally compared. An survey was also made on energy policy on the transportation sector in Europe and the U.S. For the effective energy utilization, described were enhancement of unit requirement of energy consumption (increase in fuel consumption and transport efficiency), and measures taken to widely spread petroleum substitution fuel. The paper also stated the introduction of the TDM (transportation demand management) method as a means of making travel conditions better. 47 refs., 38 figs., 31 tabs.

    For the establishment of a practical process for substitute natural gas (SNG) production, technological and economical assessments were made, and tasks to discharge for the development were discussed. In this fiscal year, the results of surveys conducted in the past five-year period were compiled, and studies were made to prepare for a smooth transition to the element research stage. Findings obtained are described below. SNG producing technologies need to be developed, with the demand for SNG increasing sharply, to further stabilize the base for SNG supply; coal which is abundantly available should be used as the material for SNG; and coal hydrogasification, among various methods for producing SNG from coal, is the most suitable in view of efficiency and cost performance. It was also found after a prolonged study for the improvement of efficiency and cost performance that probabilities were high that the yield of BTX (benzene, toluene, xylene) would increase and cost performance would improve. Besides, a basic plan and an element technology research plan were prepared for the development of the ARCH (advanced rapid coal hydrogasification) process. (NEDO)

    The status of the methane generation due to landfill with waste has been analyzed to investigate the actual circumstances of effective utilization of methane in the world and its possibility. The artificial generation of methane is 375 Tg per year among the total methane generation in the world, 535 Tg per year. The methane generation from the landfill with waste is 40 Tg per year, which becomes a rather large contribution. The methane generation from the landfill with waste in Japan is estimated to be from 130 to 520 Gg per year, which is a rather low value as a share in the world. This is caused by the sub-aerobic property of landfill in Japan, and the methane generation can be suppressed. Accordingly, there are no systems using recovered methane as energy source in Japan. In the USA, profitability of energy recovery can be established in 600 to 700 landfills among about 6,000 landfills. The methane recovery is practically conducted at more than 120 landfills. The recovered methane is used as a power generation fuel. 45 refs., 43 figs., 27 tabs.

    This study is aimed at studying for survey of gas hydrate (GH) deposit required for GH resource development and gathering of it, and further at studying for industrial utilization technology development of GH which is different in formation condition depending on kind of gas with which it reacts. The results of FY 1998 are as follows. In the study of the situation of existence of gas hydrate in the tundra, the sedimentary environment of the tundra where natural gas hydrate exists was simulated in laboratory to measure thermal conductivity of the sediments including GH. In this fiscal year, design/fabrication/calibration were conducted of the GH synthesizer and thermal analyzer. In the study of GH gathering technology in the tundra, a technology is discussed for recovering gas from GH layer and at the same time substituting CO2 hydrate for GH by blowing CO2 into the geologic layer. In FY 1998, formation/dissociation behaviors were first studied of methane/CO2 mixture hydrate. For the overall energy development of GH resource and promotion of R and D of the utilization technology, studies were made on physical properties of GH and development of the usage. (NEDO)

    Discussions were given on a sterilizing effect of ozone on Fusarium bacteria in hydroponic culture, and its effect on components in the culture solution. In an experiment, dry air with O3 concentration of 3.5 ppm was sent into aqueous solution inoculated with Fusarium bacteria at a flow rate of 5 liters per minute. The Fusarium bacteria was sterilized nearly completely in about five minutes. No change was observed in pH, EC and dissolved oxygen concentration of the O3-treated culture solution. However, iron and manganese among the soluble components have been oxidized by O3 and precipitated, hence these components must be added after the O3 treatment. In spinach culture performed on a culture medium inoculated with Fusarium bacteria, ozone water containing dissolved O3 at 0.8 ppm was flown into a urethane foam medium and vegetable roots. This treatment has resulted in reduction of the number of strains occurred with a wilt symptom below that in the section flown with distilled water. The spinach has grown normally without showing an effect of the ozone water. 15 refs., 10 figs., 3 tabs.

    The Brunei Project is a joint venture among the Brunei Government, Shell and Mitsubishi Shoji, but when its supply began in 1972, the share ownership has consisted of Mitsubishi Shoji and Shell at 45% respectively and the Brunei Government at 10%. The mutual reliance relationship among the project partners has been built gradually in such ways as Shell has built an agricultural vocational school inviting professors specialized in agriculture from England. Mitsubishi has created a large-scale cattle breeding business and produced beef cattles under the severe tropical environment, with an unfortunate result that the production cost did not balance with the market price. Recently, three Japanese agricultural engineers have succeeded at last producing tomatoes, cucumbers and lettuces through endeavors of vegetable production by means of hydroponic processes. The Brunei Goverment is also planning to cultivate fish and shells. Meanwhile the voices from the working site stress strongly that the operation has been continued with the safety-first concept at all times.

In Item 1, investigations were given on effects of hydrogenation treatment for a heavy circulation solvent in the coal liquefying reactions imposed on yield and nature of the product oil. Liquefying reactions were carried out under the presence of various heavy solvents having different hydrogen donating performances, or iron-based and oil soluble solvents. Liquefaction rates, yields and natures of different products were analyzed to discuss the degree of hydrogen donating performance of the solvents, the using conditions for the catalysts in the primary liquefying reaction, and the reaction conditions to enhance the product oil yield. In Item 2, hydrogenation treatment was given on the heavy oil fraction of the product oil obtained from the liquefying reaction using a heavy circulating solvent. The result was compared with the result on the medium oil fraction. Light oil fraction obtained from brown coal liquefaction was reformed to manufacture the reformed oil for engine tests. In Item 3, nature analysis and combustion tests were performed on the light oil fraction of the liquefied oil using brown coal as the material, and on the hydrogenated oil as a diesel engine fuel. The reforming effects were discussed from the amount and nature of the exhaust gas. (NEDO)

    For the purpose of contributing to the reduction in the energy consumption in the paper/pulp industry which is an industry of much energy consumption in Indonesia and to the stable energy supply in Japan, a model project for facilities for effective utilization of paper sludge, etc. was carried out, and the FY 1999 results were reported. Concretely, the paper sludge and solid waste discharged from the paper-manufacturing process are to be incinerated in self-combustion in fluidized bed incinerator. Further, the remaining heat is to be recovered as steam from the combustion exhaust gas for the effective utilization within plant. This verifies the reduction in energy consumption and reduction in emission of greenhouse effect gas. Activities for spread of the said facilities are to be made in Indonesia. The site for this project is FSW located in Bekasi, West Jawa. This is a private paper company which manufactures cardboard use paper of 0.5 million t/y using used paper as raw material. In this fiscal year, instructors were sent to FSW for installation/construction work according to the basic agreement and the attachment to the agreement. (NEDO)

    The Back Ho oilfield is the largest oilfield in Vietnam and at the same time is producing the largest amount of natural gas (associated gas) in Vietnam. Although the majority of the associated gas has been used in the power generation plant, a large amount of surplus gas is not effectively used because of shortage of fund and technologies. Accordingly, a feasibility study has been executed for a project to compress 20% of the associated gas into CNG, and use it effectively as automobile and factory fuel. As a result of the site survey, it was found that, although Vietnam consumes less amount of energy and emits less amount of CO2, the nation has a strong interest and a large amount of knowledge about global warming and CDM because the country is subjected to large effect of warming. Furthermore, it has been reconfirmed that introducing CNG into this territory is highly effective. Discussions have been made on places of installing the facilities, effective surplus gas utilization systems, facility specifications, utilities, and number of workers. Calculations were made on approximate cost of the facilities and the running cost. As a result of the surveys and discussions, it was determined that technological support from Japan and the Yen loan for environment with low interest rate are necessary. (NEDO)

    It is estimated that the woody biomass resources in Japan total 42.70 million t/y on a dry basis (indigenous production: 20.00 million t/y), which corresponds to 18.00 million t/y as oil. This project studies effective utilization of low-quality biomass resources now discarded, e.g., thinning materials and demolition woods, by reference to biomass utilization pursued in European and North American countries. The study activities cover the 3 areas of woody biomass wastes, current status of biomass utilization technologies in the overseas countries, and feasibility of introduction of the utilization technologies, after investigating necessity of abatement of the green-effect gases, current status of energy demands and policies, and woody biomass. Utilization of biomass resources for low-temperature heat purposes, which is the central issue in Japan, is not well established both technologically and politically. Moreover, the biomass resources are not exposed to price competition. Based on these premises, a total of 6 scenarios are proposed to promote utilization of biomass resources, including power/heat co-generation at a wood processing center, and dual firing at existing coal-fired boilers.

    This paper describes the achievement in relation with the mine waste water treatment technology utilizing biomass, from among the promotion projects for research cooperation with China. Waste water is converted into ferric iron (Fe{sup 3+}), which precipitates at low pH, by utilizing iron oxidizing bacteria which use ferrous iron (Fe{sup 2+}) in the waste water as the energy source, and is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Fiscal 1998 has performed eight site surveys with 47 persons in total. The main survey items are the study and guidance of pilot plant operation and the survey on measures to prevent occurrence of contamination by heavy metals in Wushan Mine. Additional site surveys were made at Dexing Mine and Yinshan Lead/Zinc Mine. Continued from fiscal 1997, consumables required for the pilot plant were purchased, and items of the bench-scale testing equipment used by Japan for domestic researches (an oxidation and neutralization testing equipment and a copper recovering and testing equipment) were transported to China. The operation research data of the pilot plant were put in order and analyzed. This paper summarizes the concept design of the shaft waste water treatment facilities for the north mine in Wushan Mine, and the surveys on measures for heavy metal contamination sources. (NEDO)

    Petropavlovsk-Kamchatky (P-K) city in Kamchatka, Russia is operating hot-water district heating using heavy oil boilers and waste hot water of thermal power plants as heat sources. Feasibility study was made on district heating using natural geothermal hot water and/or geothermal heat pump systems as heat sources of hot water supply for reduction of greenhouse effect gas emission. Among 3 areas including geothermal hot water, use of hot water in K area was impossible because of lower temperature and less spring water. Use of hot water in P and UP areas was impossible as primary hot water because of temperature drop to 64 degrees C during hot water supply toward P-K city. The building heating operation test was carried out using the geothermal heat pump system installed in a newly drilled heat exchange well of 100m deep. As a result, sufficient heat recovery was achieved for heating. If all of 49 boiler houses for heating are replaced with such geothermal heat pump systems, CO{sub 2} reduction was estimated to be 520,000t/y. (NEDO)

    This project is aimed at surveys and researches on operation, economic efficiency and performance evaluation of solar thermal power generation systems, and test methods, e.g., for aging the materials for their devices, in order to establish the methods for evaluating their performance. For operation of solar thermal power generation systems, a feasible system is a hybrid with another system, e.g., thermal power or nuclear system. For economic efficiency, heat-storage capacity will be based on power generation for around 4 hours a day for a solar system to be installed in Japan. The construction and light/heat-collecting costs should be reduced to around 300,000 yen/kW and 13,000 to 21,000 yen/m{sup 2}, respectively, in order to keep the power generation cost at around 23 yen/kWH. The energy analysis of solar thermal power generation, based on the data given by the industrial correlation tables, indicates that the total energy required for construction of the system can be recovered in 2 to 3 years. Also outlined are construction of a 1MW pilot plant and its facilities, and designs of the pilot plants with a curved surface or tower type light collector. A total of 12 types of reflection mirrors are screened for establishing the air-exposure testing methods. Methods for treating back surface edges of the reflection mirrors are also investigated.

    Designing a vessel to sail oceans for an extended period of time requires statistical estimation on different hull responses to waves. To meet the requirement, it is necessary to accurately identify hydrographic conditions (particularly waves) which are considered to be encountered by the vessel. This paper makes clear the statistical characteristics of the wave statistics table presented by Fang et al, and compares them with other processes for discussion. This statistics collection is based on data collected in China, Hong Kong and Japan, including those collected in the Sea of Japan, the Yellow Sea, the North Sea, the East China Sea and the South China Sea. It was found that these data provide results slightly lower than the long-term estimation values derived from data of the global wave statistics (GWS) prepared by Hogben et al. The cause for this was found attributable to the format of the statistical data, especially setting of wave height classes. However, since the data provided by Fang et al include items of detailed information on small sea areas near the Chinese coast lines, the data are thought to provide useful information source in investigating long-term hull response characteristics relative to spatial spread of the sea areas in the North-west Pacific Ocean. 15 refs., 5 figs., 2 tabs.

    For the purpose of contributing to the resource recycling and global environmental preservation, the R and D of metal base scrap regenerative utilization technology were conducted, and the report on the finally obtained results was summed up. As to the technology to remove impurities by the solid phase treatment, the Cu removal rate of more than 96% was made possible by the low temperature fracturing technology, and that of more than 90% by the hue difference discrimination separation system technology. From the results of the FS on the low temperature fracturing technology applied to car scraps, it was found out that the present price condition is not economically efficient in the present price condition, but a possibility of achieving the removal rate of 54% in the initial plan was obtained if applying the hue difference discrimination separation system to the pretreatment. Concerning the Sn removal, the Sn removal rate of more than 70% was obtained by the gaseous phase sulfuration method, and that of more than 50% was obtained in Sn removal/Cu removal/Zn removal by the oxidation reaction method. The targets were achieved. Relating to the treatment of impurities by melting (liquid phase), the Cu removal/Sn removal technology under reduced pressure was effective in vacuum melting furnace of 2-ton scale, but the needs for the development of large capacity plasma torch were recognized in that of 40-ton scale for practical use.

    For the purpose of securing water stably and preventing water pollution in the Philippines, R and D were carried out on a wastewater treatment and water reclamation and reuse system which is easy to operate and maintain and low in cost through the research cooperation between the Philippine Industrial Technology Development Institute and Japan. According to the survey result of statistical data concerning water pollution load structure by industrial wastewater classified by the industry in the Philippines, enumerated are the food manufacturing industry, paper pulp manufacturing industry, and the textile dyeing industry as those greatly affecting water pollution in BOD exhaust and wastewater, etc. Consequently, with Ram Food Product Co. of vegetable processing and Solid Mill Co., of textile dyeing as plants to be studied, a wastewater treatment test was performed in a laboratory scale. From the result of the test, the pilot plant was basically designed to have 'anaerobic + aerobic treatment + tertiary treatment' for the treatment process, with an one-tank type UASB method used as the anaerobic treatment, with a sand filtration + activated charcoal treatment as the tertiary treatment, and with the cost effectiveness for water reuse set to be examined.

    Under the hydrogen-utilizing international clean energy system technology project WE-NET (World Energy NET Work) in fiscal 1998, researches and studies were conducted to clearly define safety designs and to improve on accident-and-safety analyses. In relation with system safety design, investigations continued into Japanese and foreign manuals and regulations about the handling of hydrogen and its peripherals, and safe design guidelines (draft) were compiled. Anomalies and accidents supposed to be typical of each of the systems concerned were investigated. As for accident-and-safety analyses, incorporation of a turbulence model was studied in relation to models representing the leak, evaporation, and diffusion of liquid hydrogen, and improvement was achieved when the scope of evaluation was enlarged concerning the hydrogen detonation model. The integration of the two models was discussed for the due evaluation of a series of processes of liquid hydrogen leak, evaporation, diffusion, and detonation. Calculation was performed for two assumed accidents, and the results were found to justify the integration of the two models. (NEDO)

    Described herein is development of direct steel-making using high-temperature reducing gas. A light hydrocarbon fraction (boiling point: 230 degrees C or lower), produced by steam cracking of vacuum residua, is reformed into a reducing gas in the presence of steam, using heat to be supplied by a nuclear plant which produces high-temperature gases for various purposes. This reducing gas is then supplied to a plant for producing reduced iron. This project has established basic techniques for designing, constructing and operating a direct steel-making pilot plant, to be connected to a 50 MWt high-temperature gas test furnace. The closed iron-making system and greatly reduced SOx emissions to several fractions of the current level are some of the expected effects. The environmental impacts of the high-temperature gas furnace will be on a level with those associated with a light-water reactor. Cracking and gasification of vacuum residua, which has found limited purposes so far, should expand its applicable areas and reduce dependence on fossil resources, leading to diversification of energy sources. The overall thermal efficiency of the high-temperature gas furnace is expected to increase to at least 60%, because its high-temperature gases of around 1,000 degrees C can be used for heating processes, and the waste heat can be further used for generation of steam for power production.

    This survey focused on the end of the more promising companion and promoting the international cooperation on chemical CO2 fixation and utilization technology. As a result, the way of the carrying-forward of the international cooperation with more than one companion could be arranged beforehand. It led to getting an arrangement about a secrecy agreement respectively with Lurgi company and ABB company in Europe, and to providing a catalyst sample developed by RITE to implement an examination by the other party and to show related technical information. In addition, it concluded a cooperation agreement about a total system of the chemical CO2 fixation and utilization technology and methanol synthesis with ZSW. In Australia, negotiation about international cooperation with CSIRO which is a federal research organization and CRC (Cooperative Research Centre) for renewable energy has been started. The ideal circumstances are being ready for the chemical CO2 fixation project for which the international cooperation with the country where the natural energy is rich like Australia is essential when coming to practical use. To do alternating current with further high density in the following year it is desired to build a concrete study cooperation system. 1 fig., 4 tabs.

    Described herein are the results of the FY1994 research program for international joint technology development for solar energy utilization systems. The joint study with an Indonesian research institute takes a model of lumber drying plant for the design and feasibility study. All the parts it needs are technically available in Indonesia, except carbon fiber sheets and electronic devices for controlling purposes. The drying cost is higher than that of a plant which procures charge-free wood fuel, but lower than that of a plant which procures fuel at 30$/t. A cacao drying plant model is also studied. The feasibility study shows that the initial investment for the blowing-up model is much higher by 60% to 100% than that for the conventional plant. Its fuel cost is lower by 11% than that of residual oil but 27% higher than that of wood. 4 figs.

    Efforts are made under this project to develop a wastewater treatment/regeneration system, easy to operate and maintain and low in cost, jointly with a Philippine research institute. Technologies are transferred to this institute concerning research and development, system designing, operation, maintenance, and management. The goal is to disseminate such technologies in the Philippines. As for fiscal 1999 endeavors, emphases are placed on the items described below. The Container Corporation which regenerates waste paper and the RAM Food Corporation which manufactures canned foods and pickles are selected as the sites for pilot plant research. Wastewater discharged by the two corporations is subjected to laboratory-scale wastewater treatment (combination of aerobic/anaerobic treatment and activated carbon adsorption), by which a pilot plant wastewater treatment process is determined and designing conditions are defined. As for activated carbon for advanced wastewater treatment, a fine grain sample, which is the lowest in price among activated coconut shell charcoals produced in the Philippines, is acquired, and tested for performance. A wastewater treatment pilot plant is complete at the Container Corporation, and has started operation. (NEDO)

    In recent years, a system has been proposed that utilizes river heat, air-heat, exhaust heat from a cooler, etc., in addition to natural energy for the heat pump. With the introduction of such system, the amount of energy used and that of CO2 exhaust will be greatly reduced, but annual expenses will be increased as it stands. In order to improve the cost efficiency of the system, a proposal has been made for the introduction of an economic policy such as the carbon tax and a low interest financing system. With these matters in the background, the subject study predicts the production of solar cells in the future and, on the basis of this production, determines the price, conversion efficiency and equipment energy of solar cells in the future. Using these values and taking into consideration the introduction of the carbon tax and the low interest financing system, the optimum area was determined for solar cells and heat concentrators in a future residential solar/air-heat energy system. The carbon tax, being imposed on all CO2 discharges, had a large effect. Moreover, as the tax increased, annual expenses decreased for the solar/air-heat system. 3 refs., 6 figs.

    It is urgently necessary for the Philippines, which has no promising energy source to replace imported oil and lacks hard currencies, to reduce dependence on oil. The country, consisting of a number of islands, has faced many difficulties in construction of large-scale power transmission grids covering wide areas, which greatly retard development of local industries and dissemination of electricity. Therefore, great expectations have been placed on the techniques this project plans to develop for utilization of wastes as the energy source. This 5-year project (FY 1990 to 1994) is aimed at joint research and development of (thermal decomposition/gasification and power generation system) for transforming large quantities of wood-wastes/agri-wastes left unutilized into electric power, in which thermal decomposition/gasification of the wastes is combined with gas engine/power generator systems, and thereby to establish the systems suitable for the developing country. The major R and D results obtained in FY 1992 as the third year include on-the-spot surveys, tests for validating elementary techniques, designs and fabrication of part of the demonstration plant, and invitation of Philippine researchers to Japan.

    The WE-NET Project is a long-term project designed to ensure that an energy network technology using hydrogen becomes a reality not later than 2020. So the project cannot remain effective unless constant efforts are made to foresee future trends of technology and optimize it as the making of entire system for the project. In this project, new technologies which are not up for development are also investigated. Their feasibility should be studied, if necessary. From the foregoing point of view, new technologies are studied, collected and evaluated. Thus, useful suggestions and proposals may be made as to the course for the project to follow, as well as its research and development. Proposals highly evaluated up to FY 1995 are the hydrogen-oxygen internal-combustion Stirling`s engine, hydrogen production by solid oxide electrolysis, magnetic refrigeration technology for liquefaction of hydrogen, solar thermal hydrogen production with iron sponge technology, and hydrogen producing technology with photocatalyst. Conceptual investigation themes in FY 1996 are the hydrogen internal-combustion Stirling engine, solar thermal hydrogen production, phototransformation process, and high-temperature steam electrolysis. 9 figs., 54 tabs.

    Survey was conducted on the actual state and the potentiality of reusable energy (RE) in the South Pacific nations. The countries to be surveyed were Australia, New Zealand, Papua New Guinea, the Fiji, the Republic of the Marshall Islands, and the Republic of Nauru. The subject RE are photovoltaic power (PV), solar heat, wind force, biomass, hydraulic power and geotherm. The survey items were as follows; RE policy and promotion programs, technical level of makers, RE supply areas and population for independent/linking type electric power systems, population of non-electrification areas, meteorological data, foreign investment policy, feasibility for introduction if RE not yet introduced, and potential of promotion if RE already introduced. Propositions are as follows. Australia and New Zealand, having a comparatively large population and a stable government, are the two most important markets for RE technologies. The South Pacific nations have a markedly small population, providing a limited market for RE systems. Papua New Guinea, being a country possessing natural gas resources, has a chance of developing photovoltaic and fossil energy hybrid systems. The Fiji shows possibility for hydraulic, wind force and biomass power generation. (NEDO)

    Efforts are made to grasp the parts remaining technically unsolved of the ozone-aided technology for creating a comfortable environment, such as ozone-aided enhancement of the decomposition of nondegradable organic matters in the urban sewage and industrial wastewater. Efforts are also made to put in order and analyze data about the said technology, to isolate the current problems and the objects of technical deliberation for the future, and to examine the feasibility of the introduction of this technology. Case studies were conducted for a novel ozone-aided system and the effect is examined of the introduction of ozone-aided treatment into crowded towns, water supply systems, sewerage, and industries that handle paper and pulp, chemicals, electric power, and foods. Findings are mentioned below. The ozone utilizing technology when introduced improves the efficiency of water circulation, reduces pollutants at an excellent rate, suppresses the generation of carbon dioxide, and enhances safety of water resources and water environments. To realize such good results, however, it is important for the ozone to be high in concentration, for the accelerated oxidation and enhanced biofunction processes to be further studied, and for the system to be optimized. It is also found that a technology of appropriate ozone storage will help enhance cost reduction. (NEDO)

A solar furnace operating with solar energy, composed of a simulated solar ray collector (5kW), CPC (Compound Parabolic Concentrator), molten salt furnace and coal gasifier, is designed, fabricated and installed. The motion in the molten salt furnace is simulated to analyze the heat flux. The wet and dry type coal gasification processes are simulated with Taiheiyo-coal as the basis. For the natural gas reforming solar furnace, various types of technical information on methane reforming and oxidation catalysts are pigeonholed. The catalytic reaction testing system is fabricated. The information of carbon dioxide separation technologies, e.g., membrane-aided separation, absorption, and membrane/absorption hybrid, is collected. The treatment test with the polyimide-based separation membrane is conducted. The information is pigeonholed and evaluated for development of the elementary techniques and optimization of the total system. The preliminary study on economic viability indicates that methanol production cost is 30 yen/kg-methanol or less, on the basis of releasing no carbon dioxide in the production step. (NEDO)

    The research cooperation project on a technology to treat well waste water by utilizing biomass has used as the object the well waste water from the north mine in the Wu Shan mine in Jiangxi Province. The research included surveys on properties of the well waste water from the subject mine by means of the site survey, discussions on treatment conditions based on studies in Japan, and discussions on factors for designing a full size facility as a result of pilot plant operation research. The Japanese side has transported to Beijing the bench-scale testing equipment used for the studies in Japan (an oxidation and neutralization testing equipment and a copper recovery testing equipment). In the present follow-up project, supports were provided to the research and development activities performed voluntarily by the Chinese side by using the above bench-scale testing equipment through guiding the tests at the site and supplying consumables. Certain bacteria have capability to oxidize ferrous ions in the mine well waste water into ferric ions. Utilizing these bacteria results in sedimentation of iron oxides in lower pH zones than in the conventional method, making removal of heavy metals from the well waste water possible. As a result, such effects may be expected as reduction in chemical cost, and reduction of quantity of the produced sediments. (NEDO)

    The present study is intended to search for living organism deposition inhibiting active materials from the natural environment. Investigation on process of pollution in ocean reveals that adsorption of organic matters called conditioning occurs quickly on the surface, and the surface is covered by biofilms because of presence of bacteria and diatom in the surroundings. After the biofilms are formed, pollution occurs from living organisms, such as acorn barnacles. If the formation of the biofilms being the initial stage of living organism pollution in ocean can be controlled, deposition of large living organisms that follows the biofilm formation was anticipated to be controlled. Searches were made using this possibility as a parameter. The evaluation used a method to measure the antifungal properties specific to the bacteria. As a result of having made searches using this evaluation system, pyridylnitroalkanes were obtained. As compounds like phenethyl amines deeply involving in the deposition phenomenon were obtained, compounds having stronger activity were acquired by synthesizing the derivatives thereof. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1990 on research of coal liquefying reaction. The research contributes to developing a coal liquefaction technology as one of the methods for manufacturing clean energy and chemical raw materials from coal. In the fundamental study on the liquefaction, primarily liquefied heavy constituents in different types of coals were divided into such constituents as HI, TI, and THFI to discuss the performance and coking behavior of each constituent as solvent. Furthermore, effects of hydrogenation treatment were also elucidated. Decomposing reaction was performed on different heavy products to discuss effects of the reaction conditions. In the liquefying reaction using petroleum-based heavy oil as solvent, different shale oils were used in experiments for comparison with the case of using tar sand bitumen. In the study of reforming the product, comparison was carried out on reactions in hydrogenation treatment and contact decomposition of medium to heavy fractions of liquefied oil. A separation experiment was made on hetero compounds by means of solvent extraction and pressure crystallization of liquefied oil naphtha and light oil fraction. Effects of additive were investigated in an engine test on the stabilized and balanced light oil fraction. Discussions were given on high level utilization of heat treated oil recovered from residues in liquefaction distillation. (NEDO)

    Tehcnology for separation, recovery and fixation of CO {sub 2} was stated. In an absorption method used as a separating recovery method, CO {sub 2} in the waste gas is absorbed into a solution such as amine, heated and recovered. In an adsorption method, the CO {sub 2} is adsorbed by adsorbent such as zeolite, and recovered either by reduction of pressure or by heating. In a distillation method, the CO {sub 2} is distilled under low temperature and high pressure. In a membrane separation method, the difference of the membrane transmisison speed is used. In a fixation technology, the CO {sub 2} disposed into the ocean is liquefied by compression and forced into the deep sea through pipings. The liquid CO {sub 2} has greater density than water under 200 to 300 atmospheric pressure and clathrate is produced over the interface between the sea water and the liquid CO {sub 2} but the influence on the environment should be evaluated. As a means of recycling, synthesis of methanol or hydrocarbon with hydrogen contacting can be considered, and if such synthesis is used, fossil fuel can be reduced.

    Currently, although prevention of fluidization of asphalt using modified asphalt mixed with resin and rubber has been taken, application of such a fluidization prevention means is limited, due to the reasons of high cost and difficult quality control, particularly mainly to places in the vicinity of intersections where the traffic is heavy, on bridges and in tunnels where construction is difficult. In addition, although low penetration asphalt is used, in this case, there are problems of deterioration of wear resistance and of cracks caused by temperature stress at low temperatures. The writers have conducted a study of imparting asphalt a fluidization resistance by adsorbing light oil in asphalt on a coal-ash fluidization preventing agent (FB) mixed in advance in an asphalt mixture. This article reports a study about the influence of mixing ratio and grain size of coal-ash upon the anti-fluidization property and durability of asphalt when coal-ash discharged from coal thermal power plants is mixed into asphalt, and a confirmation of the effectiveness of the mixing of coal-ash by actual road tests. 6 refs., 22 figs., 11 tabs.

    In relation to the circulating fluidized bed boiler which reduces the amount of sulfur oxides emitted in coal utilization, a verification project was carried out on installation of the equipment and spread activity in China and the Philippines contributing to the control of environmental pollutant associated with coal utilization and the effective use of energy. At the Fanshan area, installed was a 10t/h internal circulating fluidized bed boiler. At the performance test, coal includes around 7% of impurities such as stone, and the impurities should be excluded continuously at the time of actual run. Therefore, the boiler efficiency had to be changed from 89.5% to 85.8%. Further, power generation facilities have not yet been finished, and the overall operation of boiler turbine has not been executed. At the Zibo area, a 30t/h external circulating fluidized bed boiler was installed. The boiler efficiency reached 86.1%, over the targeted value. At the Batangas area in the Philippines, a 10t/h internal circulating fluidized bed boiler was installed. The boiler efficiency reached 85.8%, over the designed value. About the coal produced in the Philippines, slagging was feared, but the combustion state was favorable. 82 figs., 21 tabs.

    Upon the development into a single law of the three liquefaction related laws, studies are started on coal liquefaction reaction and the reforming and utilization of the products. In the research on coal liquefaction reaction, the solvent ratio, change in reaction time, and change in liquefaction product constitution in case of repeated circulation of the solvent are tracked, and their relations with the liquefaction rate and yield are studied, these efforts involving the Taiheiyo coal, Yallourn coal, and the Miike coal. The Taiheiyo coal is subjected to a short-duration liquefaction reaction test. In the research on product reforming, the medium-gravity fraction from coal liquefaction is subjected to hydrogenation, and the effect of the reaction conditions on the properties and constitution of the thus-treated oil are studied. An SRC (solvent refined coal) solution of the Taiheiyo coal is subjected to hydrogenation in the presence of a Ni-Mo catalyst, and the SRC cracking rate and product properties are compared with those obtained from another solution treated with a Co-Mo catalyst. In the research on product utilization, the medium-gravity fraction from coal liquefaction is subjected to hydrogenation under three sets of different reaction conditions in the presence of a Ni-Mo/Al{sub 2}O{sub 3} based catalyst. In this process, specimens are prepared by mixing the original oil, its hydrogenated product, and a petroleum-based light oil, and a study is made about the usability of the specimens and their mixtures with petroleum-based heater oil as light oil or heater oil.

    A survey was made in relation with joint utilization of welfare device development data using an international network. Developing welfare devices requires data from ergonomic and medical systems, while the cope of the objects is wide, and the kinds are various. For proliferation of welfare devices, system compatibility evaluation including that on using environment is important, including living environments that are different by countries. The present survey has identified how data for aged, handicapped and help-needing persons are accumulated and utilized in research organizations in America and Europe for both of the ergonomic and medical areas. The survey also investigated major academic societies in overseas countries, and collected database and academic network information that support the advanced research and development. At the same time, investigations were also made on organizations and corporations who are moving forward the efficient data utilization. Welfare device and service information providing systems in Japan were investigated to compare them with the trends in other countries. Conceptions and methods were compiled to utilize data internationally and jointly. Database models for device development were considered, and a proposal was made on structuring a research and development supporting database, and the operation method thereof. (NEDO)

    Described herein are the FY 1999 results of the feasibility study on the blast furnace top pressure recovery turbine (TRT) technology in China. Government of China is promoting the steel industry policies to weed out outdated, inefficient production systems while preparing the priority guidance list to promote introduction of advanced technologies, for which the government is implementing or planning the preferential measures, including exemption from the import taxes and VAT, and subsidization of interest on investment. This feasibility study predicts the commercial based investment in the case where the dry dust collector and TRT that are the principal components of a dry type TRT system are manufactured in China and its acquisition ratio is increased on the condition that a suitable number of the systems are installed and on the premise that a dissemination model project is implemented. The results indicate that the system can be introduced at a cost a little less than 60% of the predicted investment in the dissemination model project. The cost-effect ratio varies with power price, which widely varies by region in China, and the dissemination feasibility is studied over a wide range of power price. The system has high dissemination potential, because almost all of the Chinese steel makers will have a sufficient cost-effect ratio which satisfies their investment standards, if they are granted the preferential measures from the government.

    A desiccant cooling system uses concentrated aqueous solution of an absorbent to reduce humidity, hence the resultant absorbent solution becomes dilute. Regeneration of the dilute solution uses solar heat, where the regeneration characteristics are affected by solution temperature, vapor pressure, water content, air-liquid flow rate, and other factors. Therefore, mutual relationship among these different factors were investigated, and an optimum operating condition was discussed. The regeneration characteristics of the absorbent is strongly affected by temperature of triethylene glycol (TEG). This is because vapor pressure, Ps, in the TEG aqueous solution increases as the TEG temperature rises. This means that preheating the solution is effective in regenerating the absorbent. As the regeneration progresses, the water content, Ww, decreases, and the regeneration rate decreases. This is because of reduction in the Ps in association with decrease in the Ww of the TEG. This suggests that it is important in the absorbent regeneration to reduce flow rate of the TEG aqueous solution as low as possible. Raised air temperature reduces difference in vapor partial pressure between the TEG and the air, resulting in reduced regeneration rate. 5 refs., 9 figs.

    Shortcomings of solar energy are that it is subject to weather and is not available in the nighttime. The weak points may be effectively made up for when solar energy collected on a fine day is stored in the form of hydrogen energy for recovery as required. In this report, power generated by solar cells is used for the electrolysis of water for the generation of hydrogen. The amounts of the thus-generated hydrogen and hydrogen energy are determined and, on the basis of the measured amount of insolation, the solar energy availability rate (hydrogen conversion performance) is calculated. The amount of hydrogen generated in fiscal 1996 is also calculated for every month. The hydrogen generation level is quite low in the TiO2 wet type solar cell, approximately 0.2% at most. The current efficiency is fairly high in hydrogen generation using electrolysis, which is approximately 96-97%. The efficiency is higher when several units of electrolyte are connected in series until the solar cell optimum voltage is attained. A linear relationship is found between the daily summation of insolation and the amount of hydrogen generated. 1 ref., 7 figs., 2 tabs.

    A study was made of the periodic steady state of the annual cycle solar energy system with seasonal heat storage at a practical operation. Cold heat in winter and warm heat in summer are stored in the seasonal storage tank, and these are each used in shift until when demand for cold/warm heat appears. Moreover, gap in quantity of cold/warm heat going in/out of the heat storage tank during a year is filled by natural energy such as solar energy, so that the system can be operated in annual cycles. Studies were conducted of the periodic unsteady term and the problem on lowering of performance during the term such as the periodic unsteady term of water temperature inside the seasonal heat storage tank and temperature of the soil around the storage tank, and the level of lowering of performance during the term, necessity of additional operation/control at the start of operation and aged deterioration of the system. Within the assumption, even if starting operation in any time of the year, the system could show the performance almost expected from the first operation year with no additional system operation and control required only at the start of operation. It is thought that the heat source selection control of heat pump largely contributes to this. 4 refs., 5 figs., 3 tabs.

    From the viewpoint of energy utilization stated above, blast furnace top pressure recovery turbine (TRT) unit installability was studied at Bhilai Steel Works of Steel Authority of India, Ltd., Bokaro Steel Works of Steel Authority of India, Ltd., and Visakhapatnum Steel Works of Rashtriya Ispat Nigem. The energy consumption rate at an Indian steelmaking plant is 8Gcal/t-steel, which is larger than 5-6Gcal/t-steel of Japan and therefore needs improvement. Out of the blast furnaces in India, 26 are larger than 1,000m{sup 3}, and two of them are provided with a TRT device of now-defunct Soviet Union manufacture. The blast furnaces were examined for pressure at the top, amount of gas at the top, amount of dust, and safeness in operation. The No. 2 blast furnace of the Borkaro plant was selected for the project, and studies were made for a wet type TRT device. Improvements to be achieved by TRT device installation were calculated to be a TRT output of 5,900kW, power output of 49,100MWh/year, saved crude oil amount of 12,990toe/year, and CO2 reduction of 40,200 tons-CO2/year.

    At present, measurement of wet density and water content by radio isotope (RI method) is used for filling management. It is supposed for filling in road construction that putting-out thickness of banking material reaches nearly 1m in the future rapid construction, however, use of RI method is difficult because of inserting and installing of a radiation source rod, large measuring apparatus, and the legal regulation on radioactivity intensity. Application of resistivity measurement was thus considered. Since resistivity has the same parameter as compaction curve, and monotonously decreases with an increase in water content by volume, it is applicable as construction management index. The management reference of resistivity (Rm) is set by plotting of a compaction curve and corresponding resistivity curve, determination of the reference resistivity (Ro) corresponding to a maximum dry density and optimum water content ratio, and setting of the allowance to Ro according to soil or application. It was clarified that Rm is applicable as set for every filling material. 1 ref., 10 figs., 2 tabs.

    For more precise electrical prospecting, the new multicore cable was developed to allow high-density measurement by conventional equipment. Since conventional multicore cables are inferior in cost, length and weight, the new cable is composed of an n-conductor cable, two n-conductor male connectors and n lead wires. For connection of the multi-conductor cable and lead wires, cable sheath is peeled at n points at specific intervals. Sheath of the k-th conductor is peeled at k-th point from the terminal, and restored for insulation after connection of the conductor and lead wire. The male connectors are attached to the both ends of the multi-conductor cable. Since this two-way type cable can be used at every end, the measuring equipment can measure at one divisional point after another of a long measuring line while shifting the equipment from one point to another. All measurements are perfected only with two short cables. Resistivities were successfully measured along the long measuring line of 480m long with 97 electrodes arranged at intervals of 5m. Various electrode configurations were also compared. 1 ref., 4 figs., 2 tabs.

    For the purpose of recovering sensible heat of coke oven gas (COG), the paper conducted a potential study of 'the carburetion technology using COG sensible heat,' of which the basic design is to give the endothermic catalyst reforming hydrogen production reaction directly to the components mainly including methane, and the R and D for establishing it as an industrial technology. In the R and D, the optimum process was studied in terms mainly of the dry pretreatment technology and the catalyst reformation reaction of hydrocarbons such as methane. As a result, the inhibition of the progress of the reforming reaction, which was a difficult problem at first because of the catalyst poison of associated components, could be avoided by making conditions for development/reaction of solid solution appropriate. Further, as to the associated coal tar which was regarded as carbon deposition source, a possibility of the process for converting it into the light chemical energy was recognized. Further, in FY 2000, survey was made on the solid electrolyte oxygen separation technology to which attention was paid as a chemical energy conversion technology for heat energy and which is closely related also to the energy structure of iron making plant.

    The research is conducted in cooperation with Industrial Technology Development Institute of the Philippines, and aims to solve water related problems such as unstable water supply and water quality pollution though developing a waste water treatment and recycling system which is easy to operate and maintain, low in cost, and usable in the Philippines. Fiscal 1998 is the second year of the project. Statistics are studied about the load that each industrial branch imposes on water for its pollution, and it is found that food manufacturers, paper pulp mills, and fiber dyeing plants are heavily responsible for water pollution. A method consisting of single-tower UASB anaerobic treatment and activated sludge treatment is applied as a water treatment process to Ram Food Products Corporation, and its optimization is studied. A removal rate 60% is achieved after a 12-hour treatment period at a COD (chemical oxygen demand) rate of 8g/liter/day. A method consisting of coagulating sedimentation and activated sludge treatment is applied to the waste water from a Solid Mill Corporation dyeing plant, when it is found that the water after ultimate treatment is almost colorless and that COD is 76mg/liter and BOD (biological oxygen demand) 13mg/liter, and these suggest that the waste water is recyclable. Since it is low in COD removing rate, the application of anaerobic treatment to high-concentration water after washing is not appropriate. (NEDO)

    For the purpose of developing combustion systems in which environmental pollutants are less emitted from coal-fired boilers, conducted in fiscal 1994 were a study of load followability of oxygen producing equipment, and element and basic tests on oxygen combustion systems. Dynamic simulations were made to confirm load followability of low-purity oxygen producing equipment. Further, a test was made on starting time of oxygen producing equipment. As a result of the simulation, favorable load followability was confirmed except for some of the process. The width of variation of the product oxygen purity was {plus_minus} 0.7% at maximum. In the element test on oxygen combustion systems, an experiment on the oxygen combustion using pulverized coal was conducted to study heat collection characteristics of furnace and response to multi-kind of coal. A study of balance of S content, experiments on characteristics of crushing/transporting pulverized coal, etc. were added.

    The effort of fiscal 1997 at isolating the best way to introduce a relatively small amount of hydrogen into urban fuel economy was carried over to fiscal 1998. In the research of fiscal 1998, comparison was made between Tokyo and London in connection with hydrogen introduction, and a transition scenario was proposed for introducing hydrogen into Tokyo. Models were built for Tokyo and London, and studied. The result of this study was different from that obtained in the previous study, and places the two cities under similar conditions. The difference is attributed to the rapid progress in the development of the fuel cell and to the resultant reduction in cost. It is inferred that, in consideration of the transportation situation, the introduction of pure hydrogen will be the most cost-effective for both cities at least for some time to come. According to the revised data, natural gas may be procured in Tokyo as in London but the size of supply available in Tokyo is fairly smaller than that in London. Several transition scenarios covering the period up to 2025 were subjected to discussion. (NEDO)

    This review article focuses on the utilization of several catalysts during coal pyrolysis and gasification. In situ or off line catalytic upgrading of volatile matters during pyrolysis of low rank coals is carried out in pressurized H2 with different reactors to produce BTX (benzene, toluene and xylene). When NiSO4 and Ni(OH)2 are used in the hydropyrolysis of Australian brown coal using an entrained bed reactor with two separated reaction zones, BTX yield reaches 18-23%. MS-13X zeolite and USY zeolite mixed with Al2O3 are effective for producing BTX with powder-particle fluidized bed and two-stage reactors, respectively. Catalytic gasification is described from a standpoint of direct production of SNG(CH4) from coal and steam. When K2CO3 and Ni are compared for this purpose, Ni catalyst is more suitable at low temperatures of 500-600degC, where CH4 formation is thermodynamically favorable. Fe and Ca catalysts can successfully be prepared from inexpensive raw materials and are rather active for steam gasification at {>=}700degC. The use of upgrading and gasification catalysts is discussed in terms of preparation, performance, life and recovery. 27 refs., 6 figs., 2 tabs.

    A feasibility study is conducted for an Uzbekistani plan for effectively utilizing associated gas at its Kokdumalak Gas Field. The effort will lead to a clean development mechanism in the future. The associated gas and off-gas now being totally burnt in a flare stack will serve as raw materials for the recovery of LPG (liquid petroleum gas), NGL (natural gas liquid), etc. The amount of total investment is US$82,003,000, with US$69,739,000 borrowed and US$12,264,000 self-financed. Thanks to the products to be recovered, there will be an energy substitution rate of 168,418 tons per year in terms of oil. There will be a huge reduction of greenhouse gas emissions of 4.52-million tons per year in terms of CO2, tantamount to the discharge of a 1000MW-class power plant. Although the project will be low in profitability, with the FIRR (financial internal rate of return) on investment before tax being as low as 10.56%, yet it is desired that, in view of the expected reduction in greenhouse gas, effective utilization of associated gas, and in view of its impact on the future development of the Republic of Uzbekistan and its society, the project will be implemented as soon as possible. It is expected that the country will enjoy various tax revenues to be created, foreign exchange by importing LPG, and earnings through emission right trading involving greenhouse gas. (NEDO)

    In this study, taking the all factors involved in the energy consumption in residential houses as subjects, the effectiveness of the solar PV system and solar thermal utilizing system in residential houses has been studied by simulating a model residential house considering the improvement of the residual environment in the future. Therefore, a model residual house is assumed, 18 kinds of combinations of construction style, cooling and heating type and solar energy utilizing form are assumed and year round simulation is carried out. The conclusions obtained by the simulation are as follows. The energy consumption in residential houses may decrease greatly by using a solar hot water supplying system. If combined with a solar PV system, the energy consumption in one year is about 8.7 to 9.7 MWh. The combined use of a solar thermal utilizing system and a PV system is more effective to reduce the second-time energy in comparison with the PV system only. 36% of the space heating energy consumption may be decreased by using the solar space heating system, but the decrease effect of the energy consumption of the solar space heating system is smaller than the solar hot water supplying system. 12 refs., 26 figs., 3 tabs.

    China is surveyed for promotion of joint implementation, which is one of the flexibility measures in the Kyoto Protocol, the Third Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change. The project aims to collect methane for global warming suppression and to use it as town gas and for power generation as well. The survey covers the 2 coalfields of Yangquan and Panjiang. The Yangquan coalfield is the largest anthracite yielding base in China, with 6 mines in operation. Power generation centering on a 100MW plant is discussed, and generation fired by a mixture of debris out of the coal preparation facility and gas is compared with another fired by town gas, on the assumption that 130-million m{sup 3} is available under the current circumstances. In the case of the Panjiang coalfield, which is expected to develop into a large coal base in the southern part of China, power generation centering on a 50MW plant fired by a mixture of debris and gas is discussed, on the assumption that 63-million m{sup 3} is collectable from the existing 5 mines. Use of town gas is also studied. When Japan's coalbed methane collection technology is applied, the gas drainage rate will be elevated to 40-35% or higher. It is desired that the use of gas drainage will be further diffused for the prevention of disasters of coal mine gas explosion. It is hoped that the use of environmentally friendly energies will be enhanced. (NEDO)

    This paper presents the environment-friendly residence `ED-1` utilizing the sunlight effectively. ED-1 of 97m{sup 2} in first floor area and 81m{sup 2} in second one has, on its roof, the photovoltaic power generation system, the solar hot water collector which supplies hot water by circulating heated antifreezing solution into a hot storage tank, and the solar hot wind collector which largely contributes to energy saving together with a hot room named an S unit on the first floor. The small S unit faced toward the south adjacent to a dining room is made of timber and thermal insulation glass. The S unit stores heat in a floor by taking the sunlight into a room in winter, while enhances a heating effect by discharging stored heat in nighttime. In some cases, duct circulation of heated wind is possible. Solar radiation of 90% can be removed by outside glass fiber screen of the S unit together with double glazing coated by special metal film. Roof material is superior in heat insulation, air tightness and energy saving, while floor material in sound insulation and heat storage. The target for reducing energy essential to human life by 70% was thus nearly achieved. 1 fig.

    Slag released from an electric furnace consists mainly of waste steel. There are two types of slag, namely, oxidized slag and reduced slag. Reduced slag, which is generally in the form of powder, is difficult to recycle as compared with oxidized slag. However, with a hydraulicity, some reduced slag is expected to be useful as hydraulic material. Test results obtained here show that the hydraulic properties of reduced slag powder can be improved by mixing it with gypsum and that the resultant mixture can serve to improve the prooperties of soft clay. Another study is made to determine the potential, as hydraulic material, of mixtures of reduced slag powder and waste gypsum material with a high gypsum content released from an oxidized titanium production process. The hydraulicity is found to develop as a result of the formation of a hydrate of calcium aluminate which is contained in the slag. Addition of water to the hydrate and gypsum cause the formation of ettringite, leading to an increased uniaxial compressive strength. These findings indicate that the above-mentioned mixture can be useful to improve the hydraulic properties of coal ash to be disposed of at landfill sites. 5 refs., 5 figs., 1 tab.

    For the realization of the cycling recycle society, it is important to promote recycling using glass waste for CO2 reduction and effective use of resources. The paper described the FY 1998 results of the development. It included the classification by which the composition of the particle sizes required for recycled products will be made possible, basic studies for low-cost pulverization/separation of foreign substances, and tests on heightening of process accuracy. Relating to the artificial synthesis of feldspar/pottery stone using glass waste/alumina waste as starting materials, vitrification behavior was studied to find out the optimum synthesis conditions. Glass waste of 60% and aluminum hydroxide of 40% were mixed at calcination temperature of 1,100 degrees C for more than 1 hour. Properties of the artificial feldspar/pottery stone were similar to those of the natural one. As to the utilization of glass waste to hydrothermally solidified materials, high-strength solidified matter without crack was obtained in the three-component system of G powder/hydrated lime/gypsum. Concerning the production of eco-glass block, a study was made on the size and mixing ratio of the cullet waste which is very soluble and has no effects on performance. The paper touched also on the R and D of the environmentally friendly type system using multi-functional hybrid materials. (NEDO)

    As an energy conservation method for a model building, the following eight methods were selected and trially calculated of the effects. 1) adoption of high efficient illumination apparatus, 2) introduction of an illuminance control system, 3) cooling water secondary pump with invertor, 4) ventilation control for parking lots, 5) heightening of the established temperature, 6) improvement of the 24-hour run chiller, 7) elevator with invertor, and 8) introduction of the photovoltaic power generation. As a result, it was found out that energy was totally reduced by about 3,837.4 MWh/yr or 25.6%. If viewed from the amount of reduction in greenhouse gas, the amount of CO2 emitted from office buildings, approximately 0.22 million t-C/yr, decreases to approximately 0.16 million t-C/yr. Further, approximately 0.93 million t-C/yr, the amount of CO2 emitted from commercial use facilities such as office buildings, department stores and hotels is reduced to about 0.69 million t-C/yr, thanks to the effect of the project on energy saving buildings, which made a CO2 reduction by approximately 0.24 million t-C/yr possible. Validity of the project on energy conservation in Indonesia was confirmed. 2 refs., 55 figs., 38 tabs.

    Research and development has been performed on a technology to manufacture hydrogen effectively from water utilizing solar beam and using an organics oxidizing and reducing system as the intermediary, and its achievements in fiscal 1984 was reported. With regard to the process in hydrogen generation stage as the first step, water dissolvable rhodium complex was synthesized to improve the process having been developed in the previous fiscal year. Its photo-hydrogen generation capability was discussed. In the rhodium complex of ligand having sulfonic acid group for water solution, a system using only water as a solvent was discovered to show the photo-hydrogen generation capability equivalent to or greater than the system of organic solvent and water using non-water dissolvable rhodium complex. In the stage of reduction of oxidized type organics by water as the second step, discussions were given on photo-electrochemical behavior of iron oxide sintered electrodes. Photo-hydrogen generation was investigated by retaining the electrode potential to a potential generated by beam irradiation onto the iron oxide sintered electrodes, and using a system of water dissolvable rhodium complex and rhuthenium complex. As a result, a possibility of recycling the materials was discovered. (NEDO)

    It is urgently necessary for the Philippines, which has no promising energy source to replace imported oil and lacks hard currencies, to reduce dependence on oil. The country, consisting of a number of islands, has faced many difficulties in construction of large-scale power transmission grids covering wide areas, which greatly retard development of local industries and dissemination of electricity. Therefore, great expectations have been placed on the techniques this project plans to develop for utilization of wastes as the energy source. This 5-year project (FY 1990 to 1994) is aimed at joint research and development of (thermal decomposition/gasification and power generation system) for transforming large quantities of wood-wastes/agri-wastes left unutilized into electric power, in which thermal decomposition/gasification of the wastes is combined with gas engine/power generator systems, and thereby to establish the systems suitable for the developing country. The major R and D results obtained in FY 1990 as the initial year include negotiations with the Philippines, on-the-spot surveys for the demonstration plant sites and conditions, and conceptual designs of the demonstration plant.

    This paper reports the survey results on evaluation of PV power generation in fiscal 1994. (1) On the evaluation technique of energy pay-back time, foreign trial calculation examples by integration method were surveyed. However, there were not many study examples, and the calculation basis of input energy was also ambiguous. The calculation result by input-output analysis in Japan gave the value more than that by integration method, pointing out that indirect input energy is essential. (2) On the evaluation technique of the degree of environmental contribution, CO2 emission of the PV generation system installed on ordinary housing roofs was calculated to estimate reduction of CO2 emission and cost. As a result, PV power generation as reduction measures against CO2 brought a little cost increase. (3) On the latent scale of PV power generation, it was estimated to be nearly 191GW although under no restriction. It was a considerably large value as compared with the current power generation capacity in Japan. 4 tabs.

    This paper describes the achievements in the Sunshine Project in fiscal 1992 in studies on liquefying reaction in coal, and reforming of the products. High conversion rate was attained in the co-treatment of bitumen and Taiheiyo coals by using highly dispersing oil soluble solvent without performing coking, even if the asphaltene concentration is high. When a very highly acidic trifluoromethane sulfonic acid catalyst is used, hydrogenation and conversion to solubilized low molecules is possible even with a solvent having low affinity with coal. Swelling effect by tetralin is remarkable in pulverized coal, and the conversion rate was improved greatly under high-pressure hydrogen. When naphtha of the Wandoan coal liquefied oil is given extraction treatment with base and acid/base, the gas production decreases noticeably when hydrogenating and refining the extracts, resulting in reduced hydrogen consumption and improved oil recovery rate. Furthermore, when the extraction treated naphtha is hydrogenated, denitrification can be achieved completely. Kerosene and light oil liquefied from the Wandoan coal were cracked by fluidity contact, whereas the light gravity product yield due to the decomposition was found low because of containing a great amount of two-ring aromatics. The pressure crystal deposition method using solvent is effective in separation of high-melting point compounds including anthracene from heavy gravity oil. (NEDO)

    Efforts are put into the study of direct iron making for use in a closed system where heat energy from a multi-purpose high-temperature gas furnace expected to be developed in the near future will be utilized for iron making. The researches, carried out for the establishment of technologies necessary for designing, building, and operating a pilot plant dimensionally suitable for connection to a 50MWt multi-purpose high-temperature gas furnace, cover the plant total system, a high-temperature heat exchanger, ultrahigh-temperature alloys, high-temperature insulating materials, a reduced gas generating unit, and a reduced iron making unit. When the effort is evaluated as a whole, it is found that the newly developed system is effective in preventing pollution, emitting but 0.1Nm{sup 3} of SOx per 1 ton of crude iron against the 0.4-0.9Nm{sup 3} emitted by a blast furnace/converter iron making mill. It is also found effective in reducing fossil fuel dependence and in enhancing energy source diversification. When it comes to energy conversion efficiency, furthermore, it is shown that the new system achieves a rate of 60% or more while only approximately 30% is attained by light water reactor power generation and approximately 40% by a high-temperature gas furnace.

    This paper reports the result obtained during fiscal 1994 on a survey to prepare scenario for the diffusion of photovoltaic power generating systems. Introduction target planned with help of a diffusion simulation was verified by calculations using simulation models. The calculations made the following points clear: facility costs and power generation costs for photovoltaic power generation systems, amount of introduced photovoltaic power generation systems, number of facilities introducing photovoltaic power generation systems, policy cost to achieve the target, annual power generation amount, oil substituting effect, carbon dioxide reducing effect, and market sizes. Power generation cost in fiscal 2000 would drop down to 53 yen per kWh in new installation in independent houses and down to 31 yen per kWh in systems used in schools. These reductions are the result of progress in mass production as a result of positively implementing the aiding policies. The required diffusion aiding policies revealed from the simulation results include expansion of subsidy operations for house construction, introduction of the systems into public facilities performed by public organizations, aid to system introduction into private business entities, subsidy to facility investments, and enforcement of power purchase institutions. 3 figs.

    Research was made on electronic NEDO research reports corresponding to the recent extending trend of Internet. The logical structure and electronic format of NEDO research reports as document were first studied considering document disclosure and reuse of technical information. HTML as electronic format for Internet is unfortunately insufficient to describe the logical structure of NEDO research reports because of HTML's restricted description. Thus, XML which is being watched because of its possible definition of original tags was studied in place of HTML. As a result, because at present preparation of standards on XML and a compatibility for implementation of standards are insufficient, it was concluded that construction of the electronic document system for NEDO research reports is still too early. However, since adoption of XML as document format is important from the viewpoint of a property succession on Internet, preparation of the XML format file of NEDO research reports is essential.

    This report describes the effective utilization of coal ash discharged from general industry (general industry ash) as improving material of construction waste soil and deodorant for poultry industry. Coal ash is characterized by the pozzolan and self-hardening properties which are not shown in soil and sand. Coal ash having a large amount of free CaO in its composition has stronger such properties. Coal ash generated from fluidized bed combustor which is a kind of combustor of coal contains a large amount of free CaO, especially, resulting in the stronger such properties. On the other hand, coal ash has water and oil absorbing property due to its porous structure. To utilize these properties, the improving material of soft construction waste soil and deodorant for poultry industry have been selected. As a result of laboratory and field tests for the former, it was found that sufficient supporting force can be obtained. Since the protection of powder splash is required at the site, a humidification system has been developed, which can protect the splash by the humidification of 5%. The price between 500 and 1,000 yen/ton is suitable for the improving material of construction waste soil. The maximum price of the deodorant for poultry industry is 10 yen/kg. 14 refs., 40 figs., 49 tabs.

    In order to discuss effectiveness of physical exploration in the Sakonishi prospect in the Hida area, physical exploration was carried out by utilizing bored wells. This area contains the Kamioka mine, one of the major base metal mines in Japan, where electrical exploration has been attempted several times in the past. No effective results have been obtained, however, because specific resistance contrast between mine beds and base rocks is too small, and the topography is too steep making site workability inferior. As part of the investigations on geological structures over wide areas, electrical logging (specific resistance and natural potential) was performed in fiscal 1995 and 1996 by utilizing the boreholes. Induced polarization logging was also conducted on the same boreholes. A traverse line on the ground with a length of 600 m and boreholes were used to execute specific resistance tomography. Clear extraction was possible on a fault structure which is thought related with limestone distribution and mine bed creation. However, it was not possible to identify upward continuity of zinc ores expected in the exploration. Because of not large a specific resistance contrast between zinc ores and base rocks, it is difficult to find mine bed locations only from the information on the specific resistance. 5 refs., 5 figs., 1 tab.

    To suppress the emission of environmental pollutants from coal utilization in China and to contribute to stable security of Japan`s energy, demonstration of clean coal technology and consolidation of diffusion base to be introduced into China have been promoted. Demonstration program for diffusing simplified desulfurizers has been promoted. For accelerating the achievement, experts of desulfurizers were delegated to Weifang Chemical Industry Works, to support the program. Exhaust gas is introduced from boiler via water spray dust remover, suction fan and centralized stack into absorption tower of the simplified wet-type desulfurizer. In the ascending process, the exhaust gas contacts with absorbent, to remove SO2 and dust. The absorbent is blasted up through the spray nozzle. The absorbent is oxidized by the air into sulfate ion in the liquid chamber at the lower part of tower, and neutralized by hydrated lime to form gypsum. Through the continuous operation for two years, understandings were remarkably increased. However, good treatment of the tax system is required for further diffusion. Though there are no problems for ordinary start and stop, emergency operation is insufficient. There are some problems in the maintenance due to the delay of finding failures. 16 figs., 1 tab.

    This paper describes the achievements in fiscal 2000 in investigating generation mechanisms and suppression of dioxins from refuse incinerators, and in investigating non-bromine flame retardant materials (having a possibility of generating hazardous material such as bromine-based dioxin during combustion). To produce poly-chlorinated dibenzo-para-dioxins (PCDDs)/PC dibenzo furans (PCDFs) (dioxins, but not containing Co-PCB) in a small fluidized bed combustor for simulated refuse derived fuel (RDF), both of chlorine source and hydrocarbon are required. If the primary combustion furnace temperature is high and the air excess rate is low, the concentration of the dioxins increase. In addition, since oxygen shortage in temporal and spatial locals or excessive concentration zone of unburned hydrocarbons imposes great effect, promotion of turbulence mixing is important. In producing dioxins, vaporization from dust due to interference with the combustion gas, and copper and iron catalysts have great effect, whereas SOx in the combustion gas has suppression effect. Flame retardant materials can provide specific flame retardation effect to particular plastics in a temperature zone slightly lower than the combustion temperature. The paper also describes development of new flame retardant materials. (NEDO)

    For the effective utilization of solar energy at houses, a heating system using an air hybrid collector (capable of simultaneously performing heat collection and photovoltaic power generation). As the specimen house, a wooden house of a total floor area of 120m{sup 2} was simulated. Collected air is fanned into a crushed stone heat accumulator (capable of storing one day`s collection) or into a living room. The output of solar cell arrays is put into a heat pump (capable of handling a maximum hourly load of 36,327kJ/h) via an inverter so as to drive the fan (corresponding to average insolation on the heat collecting plate of 10.7MJ/hm{sup 2} and heat collecting efficiency of 40%), and shortage in power if any is supplied from the system interconnection. A hybrid collector, as compared with the conventional air collector, is lower in thermal efficiency but the merit that it exhibits with respect to power generation is far greater than what is needed to counterbalance the demerit. When the hybrid system is in heating operation, there is an ideal heat cycle of collection, accumulation, and radiation when the load is light, but the balance between accumulation and radiation is disturbed when the load is heavy. 4 refs., 8 figs., 3 tabs.

    For conversion of solar heat to transportable energy, hydrogen production by direct thermal decomposition of water using concentrated high-temperature solar heat was studied. Water vapor is injected into the tubular target with high melting point and high oxygen permeability at high temperature while heating the target by concentrated solar heat over 2000K. Oxygen in decomposed gas is discharged through an oxygen permeable membrane to extract hydrogen. Solid electrolyte is used as one of the target materials. Oxygen gas in the high-oxygen partial pressure site changes into oxygen ion by accepting two electrons at the target surface, and returns to neutral oxygen gas in the low-oxygen partial pressure site by discharging two electrons at the surface after permeation through oxygen vacancy. In the case of n-type solid electrolyte, to obtain constant permeation of a large amount of oxygen, flow of a large amount of electrons is indispensable in the opposite direction to oxygen ion. Among [(ZrO2)(1-x)(CeO2)x](0.9)(CaO)(0.1), materials of 0.4-0.5 in x seems to be useful as the target material. 7 refs., 7 figs.

    As a part of the WE-NET project, the introduction condition of hydrogen as substituting energy and CO2 reduction effect were analyzed using a global energy model. The WE-NET project aims at global-wide introduction of clean energy by converting abundant renewable clean energy into hydrogen transportable to distant consumers all over the world. The study result in fiscal 1996 is as follows. Undeveloped hydroelectric resources in the world are estimated to be 12 trillion kWh/y equivalent to the existing developed one in the world. Since the cost of the hydroelectric power generation projects over 1000MW in the planning stage is estimated to be 0.02-0.05$/kWh lower than that of other renewable energies, such projects are expected as energy source in the initial stage of the practical WE-NET project. The GREEN model was modified by adding a hydrogen analysis function, and extending an analysis period. The modified model allowed evaluation of the long-term important role of hydrogen energy, in particular, the capability of CO2 gas reduction all over the world. 28 refs., 92 figs., 56 tabs.

    To cope with the energy issue and global environmental issue, it is necessary to forcibly promote energy conservation. In the light of the present situation that in Japan only 1/3 of the primary energy consumed is effectively used, policies are being prepared for promotion of the introduction of high efficiency thermal utilization systems including `a project for formation of the environmentally friendly type energy community` promoted by NEDO. However, it is hard to say that the introduction is being actively promoted. The cause is that they do not fully understood the present status of high efficiency thermal utilization systems, procedures for introduction, subsidy system, etc. Therefore, a manual was made to present to self governments and enterprisers who are planning to introduce the system. To be concrete, there are the six systems: cogeneration use thermal supply system, unused energy use thermal supply system, heat storage use thermal supply system, waste use thermal supply system, plant surplus energy use thermal supply system, and cascade type thermal supply system. 28 refs., 38 figs., 42 tabs.

In the coal gasification using the pressurized internal circulation fluidized bed, an experiment was performed by using active alumina and Ni catalyst, where outstanding effect was identified. In the spouted bed hydrogenation pyrolysis, an experiment was executed by using iron hydroxide catalyst, but no noticeable effect was recognized. In the supercritical water gasification, an experiment was carried out by using Na{sub 2}CO2 and K{sub 2}CO{sub 3} catalysts, where it was found that the effect of the catalysts is little in the supercritical gasification reaction area of 800 degrees C. The power generation system composite with the chemical raw material production spouted bed gasification is a one-path system in which coal is gasified by the spouted bed gasification furnace, catalyst and steam are put into a heat exchanger to perform DME synthesis, and non-reacted gas is supplied as gas turbine fuel. Estimation was made on the possibility by an on-the-desk study, which requires experiments in the future. (NEDO)

    Bio-technologies including the biological CO2 fixation technology, or the green bio-technologies (GBT) are the technologies indispensable in realizing the change to a resource circulating and environment harmonizing society that accompanies economical growth, or in other words, the 'sustainable development'. In quantifying the feasibility of these technologies, the GBTs that contribute to creating Japan's international competitive power and employment were specified, and an approach to establish the realization target in 2010 was adopted, upon identifying the general condition of the related markets inside and outside the country. The GBT is the technology that makes the best use of Japan's independent strength created by combining the enzyme engineering and fermentation engineering with the 'genome science' (HEART). The targets are to substitute four million kiloliters of petroleum with a resource circulation type energy generated by the bio-technology; apply the bio-technology to about 30% of products and processes produced or used in Japan's chemical industries; and aim at creating markets by using environmental measurement and analysis, treatment of hard-to-decompose substances, and supports on tree planting as the three pillars.

In this survey, a regional model survey was conducted as environmental load reduction measures using highly cleaned coal which were taken in fiscal 1993 and 1994. Concretely, a model system was assumed which combined facilities for mixed combustion with coal and other energy (hull, bagasse, waste, etc.) and facilities for effective use of burned ash, and potential reduction in environmental loads of the model system was studied. The technology of mixed combustion between coal and other energy is still in a developmental stage with no novelties in the country. Therefore, the mixed combustion technology between coal and other energy is an important field which is very useful for the future energy supply/demand and environmental issues. 34 refs., 27 figs., 48 tabs.

    Oil demand is expected to substantially grow in the future, and the use of oil with combustibles such as hull, baggase and waste is considered from an effective use of energy. A regional model survey was conducted as measures to reduce environmental loads where the fuel mixing combustion with coal and other energy is made the core. The domestic production amount of hull is 2.4-3.0 tons/year, which have a heating value of 3,500 kcal/kg. If hull can be formed into the one storable for a the long term (the one mixed with low grade coal, etc.), it can be a fuel for stable supply. Bagasse is produced 100 million tons/year, which have a heating value of 2,500 kcal/kg. Among wastes, waste tire, plastics, waste, sludge, etc. have a lot of problems in terms of price and environment, but each of them has a heating value during 3,000-10,000 kcal/kg. As to the coal combustion, the pollutional regulation on it is strict, and much higher processing technology is needed. The technology of coal fuel mixing combustion with other energy has not risen higher than the developmental level. Though the technology is a little bit higher in price than the coal fuel single combustion, it is viable. 38 refs., 32 figs., 65 tabs.

    Bio-technologies including the biological CO2 fixation technology, or the green bio-technologies (GBT) are the technologies indispensable in realizing the change to a resource circulating and environment harmonizing society that accompanies economical growth, or in other words, the 'sustainable development'. In quantifying the feasibility of these technologies, the GBTs that contribute to creating Japan's international competitive power and employment were specified, and an approach to establish the realization target in 2010 was adopted, upon identifying the general condition of the related markets inside and outside the country. The GBT is the technology that makes the best use of Japan's independent strength created by combining the enzyme engineering and fermentation engineering with the 'genome science' (HEART). The targets are to substitute four million kiloliters of petroleum with a resource circulation type energy generated by the bio-technology; apply the bio-technology to about 30% of products and processes produced or used in Japan's chemical industries; and aim at creating markets by using environmental measurement and analysis, treatment of hard-to-decompose substances, and supports on tree planting as the three pillars. A simulation on return on investment in GBT business suggests the effect of promoting PFI. (NEDO)

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

    Summarized herein are the materials designs/production and tests/evaluation results of heat-resistant materials, i.e., alloys, ceramic composites and carbon-based composites, which are expected to be applicable to the hydrogen combustion turbines. These have been studied since 1993, and this paper summarizes the overall evaluation results of the phase I program. The intermetallic compound as one of the candidate materials has a high-temperature strength in a range from 1200 to 1400 degrees C by optimizing elements added. However, no prospect is obtained for heat resistance at 1700 degrees C or more for the material not coated or cooled moderately. Each of the other candidate materials tested shows a bright prospect of applicability at the base material and specimen levels. The single-crystal superalloy for hybrid cooling structures has novelty in that it is free of Cr but incorporated with Si and Hf, showing approximately 10 degrees C higher heat-resistant temperature than CMSX-4. CMC and C/C are inherently excellent heat-resistant materials, and are attractive advanced composites, because they are expected to realize no-cooled blades at 1700 degrees C. (NEDO)

    An investigational study was conducted on energy recovery (power generation) in disposal of industrial waste. The capacity of power generation facilities in incineration processing of industrial waste reached approximately 200,000kW (50 facilities) in the total nationwide. The incineration-processed waste is mainly chips of wood, waste tire and bagasse. Almost all the electric power is for non-utility use, and there are no examples of selling it outside. In the metropolitan area, there is only one example of the industrial waste incineration power generation in Tochigi prefecture. This is because there are extremely very few enterprises which are sources producing the waste as target. However, if the industrial waste market is targeted, there is a future. The industrial waste has a lot of disadvantages as power generation use fuel because of its diversification, but the use of it as fuel is technically easier than the use of the general waste as RDF. Accordingly, it can be used for power generation with no need of special technology or facilities. When picking up facilities with a potentiality of high efficiency power generation from the existing incinerators in operation of persons in charge of industrial waste processing, approximately 125,000 kW can be obtained only from remodeling of the existing facilities.

    The demonstration project is carried out in at Chaili coal mine in Shangdong Province, China for installation of and dissemination activities for circulating fluidized bed boilers to abate sulfur oxide emissions associated with utilization of coal, and the FY 1999 results are reported. The operating conditions were reviewed, and some recommendations were made for improving the operation procedures. Limestone was not used for desulfurization, and furnace temperature tended to increase due to increased size of the fluidizing particles. Therefore, it was recommended to use limestone at the design rate. The boiler was operated at a load exceeding the design level, and it was recommended to limit the load viewed from extending serviceability. The boiler start-up procedure was concretely proposed to use a mixed fuel of wood and coal instead of distillate oil, in order to reduce the start-up cost. The recommendations and design support activities for improving facilities included early stage repair of the damaged refractories. For build up of the ashes in the horizontal heat transfer section, the investigated design charts for improvement by installation of ash-discharging hopper were drawn and proposed. Maintenance-related information was given, including Chinese agencies for obtaining auxiliary facilities. (NEDO)

    For collecting solar radiation data necessary for the prediction of power to be outputted by photovoltaic power systems in Japan, detailed experiments and observations were conducted with an emphasis placed on the amount of solar radiation on a slope facing north and on the amount of solar radiation broken down by wavelength. Models were analyzed, and the fiscal 1999 results were compiled. In the validation of a model of solar radiation on an inclined surface, a review was conducted using the 1-year data observed at the Takasaki station for all directions, including solar radiation on the slope facing north, and the validity of the model was confirmed. As for the validation of a model for estimating solar radiation by duration of sunshine, it was examined for accuracy using the same data, and was found to be fairly high in accuracy. For the maintenance of solar radiation data for each wavelength, continuous observation was conducted for each wavelength of solar radiation at the Takasaki station using a multi-filter spectroradiometer, and a technique was established to determine spectral distribution using the observed data. Moreover, continuous observation of global diffused solar radiance was conducted using a sky scanner at the said station and solar cell power generation characteristics was continuously monitored.

    This paper reports the achievements in fiscal 1999 on development of gas hydrate resources. As a result of synthesizing gas hydrates in deposit systems, identifying stability zones in compositions, and studying thermal conductivity and dielectric constant of the deposits, the estimation accuracy has been enhanced steadily in estimating hydrate existing areas in actual frost areas. In the collecting technologies, a proposal was presented for a system by which carbon dioxide is introduced into ground beds at the same time as recovering gases, and gas hydrates are displaced with carbon dioxide hydrates. The displacement phenomenon was verified experimentally by controlling temperatures and pressures. Even below the freezing point, the production rate of the carbon dioxide hydrates is fast if it is above minus 4 degrees C. Salt diffusion behavior important in control of the production and decomposition, and action mechanisms of production and suppression agents were made clear microscopically. Experimental and theoretical discussions were given on dynamics of the production and decomposition. The cage occupation rate of methane hydrates was quantitatively measured successfully by using the Raman spectroscopy. Hydrates of gas mixture were utilized to have verified the possibility of separating the gas mixture constituents. (NEDO)

    With an objective to utilize effectively middle to high temperature hot water type geothermal resources, R and D has been performed on a downhole pump-applied binary cycle power plant which exchanges heat energy with a secondary media in a heat exchanger, and generates electric power. This paper summarizes the achievements in fiscal 1999. This fiscal year has installed an operation control device and made partial modification therein for the hot water system testing device installed in the previous fiscal year, which was followed by test operation. Having been performed in addition were the installation of cooling water collection pumps, improvement of water storage tanks, modification of piping for injection of downhole pump cooling water, inspection of high-temperature cooling device and low-temperature cooling device, and discussions on deposits onto the downhole pumps. Furthermore, an environmental impact survey has performed measurements of precipitation, river flow rates, thermal spring, spring water, noise, and groundwater fluctuation. A survey was also carried out on transplantation of precious plants. In the single and overall test operation of the hot water system testing device, normal operation was identified. However, the operation had to be suspended because of a trouble in the downhole pump. (NEDO)

    As a method of computation of wave fields in irregularly stratified media by use of the indirect boundary element method, an induction formula was proposed in a previous report, utilizing the reference solution representing the wave field in corresponding horizontally stratified media. This algorithm applies to other types of vibration source. In computation of a wave field with the focus in presence on the ground or in the ground, the algorithm is incorporated into the computation as a vector including the reference solution as a variable. There exists no need to modify the algorithm. Once the reference solution is obtained, the wave field in the irregularly stratified media is automatically constructed by the proposed algorithm. The wave field to be the reference solution to a point source in the horizontally stratified media, is determined when the solution is obtained of the frequency/wavenumber domain by use of the reflection/transmission matrix of Kennet (1983) and converted into the solution of the spatial domain by use of the discrete wavenumber representation of Bouchon and Aki (1977). 8 refs., 2 figs.

    Experimental researches were made on rice husk charcoals processed to be used as culture media for hydroponics. Rice husk charcoals with a size of 1 mm or larger retaining the original shape of the rice husk, and with a size of smaller than 1 mm were made for use in the experiment. In the culture media made of these rice husk charcoals, the charcoal with a particle size greater than 1 mm had more air portion than water portion at 6 cm above the water level, and the charcoal with a particle size smaller than 1 mm had poor air permeability. According to the result of immersing the rice husk charcoal in a culture solution, phosphoric acid ion and manganese in the solution decreased by about 35% and calcium by about 10% in the duration of 120 minutes, as a result of having been adsorbed into the rice husk charcoal. On the other hand, chloride ion increased by about 80% and potassium and iron by about 30%, because of having been dissolved out from the charcoal. In cultivating spinach, butterhead lettuce and radish in the rice husk charcoal culture media, the culture medium with charcoal smaller than 1 mm resulted in harvest reduced by about 75% in spinach, and about 10% in butterhead lettuce. 15 refs., 13 figs., 11 tabs.

    The paper reported the FY 1998 achievement of the supercritical fluid utilization leading R and D which started in FY 1997 on a 3-year plan. In the R and D, solvolysis reaction, oxidation reaction and hydrogenation reaction were taken up in the chemical process using supercritical fluid. In the study of solvolysis reaction, the basic data were obtained on decomposition conditions of thermoplastic and thermosetting plastics in supercritical water. Further, concerning the synthesis of environmental friendly type carbonate using CO2, a conversion rate of almost 100% was obtained. About the oxidation reaction, conditions were found out for burning low grade coal in supercritical water without emitting acid gas. This is considered to lead to a possibility of the supercritical water power generation. Relating to the hydrogenation reaction, a study was made on lightening technology of heavy distillate using supercritical water, and the conditions for effective emission of methane and hydrogen were found out. As to the base technology, a study was made of metal materials with high corrosion resistance against supercritical water. (NEDO)

    In Vietnam, survey was conducted of the project in which the adoption of circulating fluidized bed boiler (CFB) makes energy conservation and greenhouse effect gas reduction possible. CFB makes a marked decrease in SOx emission possible by using limestone as combustion bed material. As a result of the survey, the thermal power plant was not suitable for the model project due to its large size. However, it was found that two cement plants and one fiber plant having coal-fired boiler were suitable for survey. Nghi Son and Bim Son cement plants are typical cement plants in Vietnam. As a result of the hearing, they were eager to adopt CFB equipment. As to environmental improvement effects, in the thermal power plant with power source loads, emissions of SOx and NOx can be reduced by 79.0% and 72.5%, respectively. Further, in Nam Dinh Textile Company, emissions of SOx and NOx can be reduced by 79.8% and 84.6%, respectively, in case of converting boiler from the existing stoker boiler to CFB boiler. (NEDO)

    For the purpose of spreading/promoting circulating fluidized bed boilers in China, survey was conducted on the confirmation of effectiveness of implementation of the model project on spread type circulating fluidized bed boilers and the appropriateness of the sites proposed for implementation. As to the model of spread type 35t/h-CFB boilers, local products are more integrated into it, taking cost reduction of equipment and secure performance/quality into consideration, and the wider-ranging technical guidance/transfer are conducted also in design/production. In China, where environmental regulations are not strict, and there are many restrictions on funds, the size of the initial investment is an important element for selection of type. Further, the market is very big, about 200 units/year. It is highly possible to realize the competitive cost level by the quantity production effect by increasing local production. Two companies, Southeast Electrochemical Co. and Fujian Prime Pharmaceutical Group Co., which were proposed as sites are financially good and are achieving substantial results. Both companies are located in the urban area, and therefore, environmental measures should urgently be taken, and PR activities for spread are highly effective. It was confirmed that the companies were fully appropriate as sites proposed for the spread type model project. (NEDO)

    This paper describes development of hydrogen gas turbines from among the comprehensive discussions on hydrogen utilizing subsystems. Hydrogen and oxygen gas turbine cycle has varying optimal conditions of plant efficiency depending on fuel patterns. The regenerative cycle may have the turbine inlet temperature at about 1,000 degrees C. The inlet pressure would be ten and odds atmospheric pressure. It is better to keep the inlet temperature higher in order to obtain high specific power. Reduction of power generation cost in using this plant requires that construction cost be decreased, and the specific power be increased if the plant efficiency (in other words, running cost) is assumed constant. Further development is required on technologies to use higher temperatures and pressures. For that purpose, discussions should be given on material development, structural design, and inspection. Hydrogen gas turbines, which present low pollution depending on combustion methods, have great significance for such social problem as environmental contamination. In terms of economy, since hydrogen gas turbines depend on efficiency and fuel unit cost, the evaluation thereon may vary depending on how well the regenerative gas turbines have been established, in addition to future change in hydrogen price and the technologies to use higher temperatures and pressures.

    This paper describes surveys on trends in overseas technologies in development plans for geothermal water utilizing power plants. In heat cycles, the binary and two-stage flash cycles were analyzed by using a generalized equation of state, and theses on optimizing working fluid properties and cycle conditions with maximum thermal efficiency were described. Theses that were described include those for criteria to select working fluids and thermal power cycles against the binary cycle using a heat source at 104 to 204 degree C. The binary cycle working fluid was found better in mixed systems than in pure systems as seen from process and economic performance. The paper introduces a heat conductivity experimenting device and data required for designing a heat exchanger. It also describes the Heber geothermal experimental plant to demonstrate reasonability of assumed working media. A fluidized bed type and a shell tube type were applied to heat exchangers at the Raft River 50 MW geothermal power plant for comparison and discussion. Fouling factor was also estimated. A discussion was given on fluidity distribution of a fluidized bed heat exchanger. Design of a heat discharge system is important for geothermal power generation because heat source temperatures are so low that more than 85% of heat that has been taken in is discharged. The paper also describes turbines and other facilities. (NEDO)
