    With relation to the coal of Indonesia, 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/distribution/utilization and environmental problems, and analyzed the situation of the coal utilization/spread by industry including the commercial/residential use. The purpose of the survey is to work out a comprehensive master plan including Japan`s international cooperation for introducing the environmentally-friendly coal utilization system to Indonesia. Coal utilization systems, the introduction of which Indonesia should study in future, were picked up, according to the surveys in fiscal 1993 and 1994. In commercial/residential and small-scale industry sectors, needed is improvement of carbonization technology for production of coal carbonization briquette. Moreover, the introduction of bio-briquette should be studied in the future. In the power generation sector, studies should be made on the introduction of technology for SOx/NOx reduction and technology for coal ash treatment including the effective use of coal ash. For the introduction of coal boilers, the combustion mixed with bagasse, which is abundant in amount, is also necessary. In the coal production sector, coal preparation technology is studied, and a method to select the optimum process was proposed through the simulation. 76 figs., 43 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.

    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.

    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.

    China is positive to introduce desulfurizing CWM plants among the typical reduction technologies of sulfur oxide emission due to coal combustion. This Japan-China joint project aims at reduction of pollutant emission derived from coal combustion by demonstration of Japanese CWM combustion technology for Chinese existing boilers, and preparation of diffusion bases. The project was promoted at Yanshan petrochemical plant in Peking as a new site. The fiscal 1997 results are as follows: field survey at the site, production of some equipment, receiving of Chinese engineers, and leading of field works. Combustion of material CWM is extremely difficult because of coal concentration as low as 65{+-}1wt% and much volatile matter. The mixture of fuel CWM and pulverized limestone is sprayed into a boiler furnace by burner for water evaporation, coal combustion and limestone burning in a combustion area of the furnace nearly at the same time. S content is fixed through reaction of SO2 and CaO with a decrease in furnace temperature. 14 figs., 11 tabs.

    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. A desulfurization CWM plant is described. It was planned, designed and constructed at Baiyang-he, Shandong Province from the end of 1995 to the end of 1996. CWM and limestone (desulfurizer) were crushed and mixed, to supply them into a power generation boiler (230 t/h). A ball mill was employed as a pulverizer. A high shear and contra-flow type intense mixer was employed as an agitator. A uniaxial screw pump was used as a slurry pump. Used CWM showed high agglomeration property, resulting in the disadvantaged fluidity. The solid concentration above 65% was difficult for the high concentration limestone mixing and crushing. The final CWM concentration was 65.5%, resulting in the decreased heating value. There were no problems in the desulfurization performance of limestone. Slugging was anticipated due to the drop of softening point of ash. Since residence time of desulfurizer was short, the initial reaction rate was significant. 30 figs., 22 tabs.

    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.

    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.

    Surveys and discussions were given on business feasibility of a wide area RDF power generation system in the Kishu and Kumano living area. The discussions dealt with as wide area as transcending prefectural borders and including the southern parts of Mie and Nara Prefectures with the city of Shingu as the central part. Wastes generation amount is estimated to be about 70,000 tons at the present as wastes that can be turned into RDF, and to be decreased to 67,000 tons in 2018. The manufactured RDF has calorific power of 3500 to 4500 kcal/kg, two to three times greater than that of wastes. The RDF manufacturing facilities installed in cities, towns and villages have capacity of 30 to 50 tons a day, with that in the city of Shingu being the largest at about 78 tons a day. Transportation can be implemented most efficiently when road transportation is used. The RDF power generation system will consist of a fluid bed furnace, a plasma type ash melting furnace, and a bag filter plus activated carbon absorbing tower. The RDF manufacturing cost will be 27,900 yen per ton of wastes in the case of the city of Shingu. In terms of business profitability, the RDF power generation must find sources to pay 21,400 yen per ton of RDF even if the power sale revenue is considered. (NEDO)

    The paper investigated the trend of and the needs for low grade coal utilization and the seeds of low grade coal utilization technology and studied usability of low grade coal in the future. Importance of low grade coal utilization was described in consideration of features of the Asia/Pacific area in the world coal market, and the trend of production/utilization of low grade coal was examined mostly in countries holding main low grade coals in the Asia/Pacific area. The trend of the technical development contributing to the low grade coal utilization was studied to make it contribute to the extraction of technologies which are regarded as effective in the Asia/Pacific area. A study was made of applicability of the low grade coal utilization technology corresponding to the needs for low grade coal utilization, and at the same time, a study was made of the effect on the coal supply/demand in the Asia/Pacific area in case the low grade coal utilization is promoted helped by the study. Focusing on technical cooperation relating to clean coal technology, a study was conducted of the trend of international cooperation in Japan and various overseas countries and the trend of new cooperation in private sectors, and a discussion was made on how Japan should act toward promotion of low grade coal utilization. 12 figs., 91 tabs.

    This project is aimed at internationally cooperating in the R and D of industrial technology and improving industrial technology of Japan. For it, the following three technologies were investigated: 1) environmental preservation technology using biotechnology, 2) technology for effective use of unused hydrocarbon resource, 3) technology for development of environmental harmony type catalyst. In 1), a survey was conducted of applicability of biological surfactant to prevention measures of pollution by heavy distillate. It showed that part of the biological surfactants is reaching a stage of its being industrially produced by gene recombination bacteria, but as a whole, biosynthetic genes have hardly been elucidated. In 2), a survey of high-grade treatment technology of petroleum coke was made. It pointed out that it is necessary to develop a technology which makes the most of features of petroleum coke and allows defects. In 3), scientists and engineers of Japan and Europe searched for themes on which they can jointly study in the fields of NOx removal catalyst, up-grading of fuel, and development of catalyst combustion of fuel. 287 refs., 136 figs., 128 tabs.

    Urban waste RDF manufactured by cities, towns and villages in the western area of Saitama Prefecture are collected on a wide area basis to perform high-efficiency power generation using the RDF as fuel at the Taiheiyo Cement Chichibu Factory. Incineration ash therefrom is regenerated together with ashes generated in other incineration plants in the prefecture to be used as civil engineering and building materials, by using the eco-cement production facilities in the above factory. Evaluation was given on business feasibility of the new wide-area treatment system for wastes and incineration ash treatment aimed at zero emission. The result of the discussion revealed that the business may be realized if the following conditions are met: cities, towns and villages will undertake expense outlay of at least 50,000 yen per ton (including transportation cost), as well as the expense for RDF treatment corresponding to the above ash treatment cost; electric power can be sold at about the same price as the purchase menu for the surplus power from wastes power generation (10.2 yen/kWh); the cities, towns and villages will utilize the eco-cement positively in public civil engineering works upon paying the reasonable price for the eco-cement; high-rate subsidy will be applied; RDF will be supplied on a planned basis; and agreement and cooperation are provided by the concerned areas.

    In order to study coal production processes, an estimation study was carried out on coal originating materials by using biomaker analysis. Test samples are original coals collected directly from a mine in Hokkaido (not having been subjected cleaning). Mixing and solvent extraction were performed after pulverization, and then tests were given on saturated hydrocarbon components divided by using a silicagel column chromatograph for the present study. It can be known from n-alkane distribution in the coal that low molecular alkane increases with increasing degree of coalification. Artificial coal made by wet-heating Metasequoia leaves contains only little n-alkane. Diterpenoid compound exists in the Taiheiyo and Akabira coals. Tetra-cyclic diterpernoid is contained abundantly in subtropical coniferous trees, serving as a parameter for warm environment. The compound is contained also in the Fushun coal, but not in Indonesian coals. Hopanoid constitution shows very high similarity, but H/C atomic ratio may vary largely even if the coalification is at the same degree. This is likely to be caused from difference in originating materials. Hopanoids are bacteria attributed substances, whose activities are not affected by the originating materials. 2 figs., 1 tab.

    This report relates to the designing of functional materials that decompose in response to various signals. A derivative of {alpha}-bromomethylstyrene is caused to act on the living anions of {alpha}-methylstyrene for the synthesis of a pyrolytic polymer having unsaturated groups at its terminals. The terminal double combinations of this polymer split under the influence of heat, acid, or base for depolymerization which is quantative, and the decomposition temperature may be controlled by replacing terminal phenylallylic groups with methyl groups or phloro-groups. Furthermore, a novel polythyramine polymer is synthesized with its principal chain constituted of NCH2CH2Si, the principal chain easy to disintegrate when exposed to an electron beam. The polymer is signal-responsive and may be patterned by use of an electron beam. As a temperature-responsive polymer with the hydrolytic feature controlled, poly(thyroxy ethylene glycol) is obtained from a derivative of diaminosiloxane and oligo-oxyethylene. This is a high-mobility, temperature-responsive material whose hydrolysis may be controlled. 3 refs., 2 figs.

    With relation to the coals delivered as common samples in the coal fundamental technology development project, an experimental study was conducted on agglomeration characteristics and reaction characteristics in the fluidized-bed coal gasifier. For the experiment, used was a fluidized bed gasifier inserted with a cone-shape dispersion plate with a nozzle in the center. After raising the temperature of the gasifier up to 773K, gasification was conducted sending to the gasifier air from the nozzle and steam from the dispersion plate. The mean particle diameter and gas concentration of chars were measured till the temperature reaches 1373K. As a result of the experiment, it was confirmed that the carbon conversion ratio increases with a decrease in coalification degree of the coal. Moreover, influence of the coal kind was markedly observed at the grid zone of the lower part of the bed, and it was clarified that the lower carbon content ratio the coal kind has, the faster the speed of CO formation and water gasification get. The agglomeration temperature of charcoal which is a product of the condensate is lower by as many as several hundred K than the point of softening, and it was considered to be necessary to study the relation with the temperature distribution in the bed. 3 refs., 3 figs., 1 tab.

    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.

    In relation to softening, melting and solidification of coal during heating, the effect of heating rate and nitrogen gas pressure on viscosity change, and change with time in the yield of pyridine extract were measured to study the mechanism of viscosity change. In experiment, six kinds of coals were used, and their needle penetration and dilatation were measured using compacted disk coal pellets. The coking and slight coking coal heat-treated under the same condition as the above experiment were used for pyridine extraction. As the experimental result, the apparent viscosity during coal heating was dependent on heating rate, nitrogen pressure and coal kinds. The minimum apparent viscosity decreased with an increase in heating rate and nitrogen pressure, and approached to a constant value. Like apparent viscosity change, the yield of pyridine extract was also dependent on heating rate, and its temperature range nearly agreed with that of apparent viscosity change. It was suggested that the viscosity is dependent on not only the mass fraction of plastic intermediate but also temperature and the relation between plastic intermediate and other components. 3 refs., 5 figs., 1 tab.

    Experiments were carried out to learn methanol sorption characteristics of heat-treated coal. When Taiheiyo coal is heat-treated at 125{degree}C, performed with a first methanol adsorption at 25{degree}C, and then desorption at 25{degree}C, a site with strong interaction with methanol and a site with relatively weak interaction are generated in test samples. A small amount of methanol remains in both sites. Then, when the methanol is desorbed at as low temperature as 70{degree}C, the methanol in the site with strong interaction remains as it has existed therein, but the methanol in the site with relatively weak interaction desorbs partially, hence the adsorption amount in a second adsorption at 25{degree}C increases. However, when desorption is performed at as high temperature as 125{degree}C, the methanol in the site with strong interaction also desorbs, resulting in increased adsorption heat in the second adsorption. The adsorption velocity drops, however. Existence of methanol in a site with strong interaction affects the adsorption velocity, but no effect is given by methanol in a site with weak interaction. 3 refs., 4 figs.

    Three typical Japanese coals of non-coking coal, coking coal and anthracite were heat-treated with KOH, and change in their pore structure was examined by absorption of N2, X-ray diffraction and TEM observation. In addition, the relation between a coal rank and pore structure was also studied by absorption experiment of N2. In experiment, the mixture of coal and KOH in a nickel holder was heat-treated in N2 gas flow at heating rate of 2{degree}C/min, and held at a fixed temperature for one hour. To clarify the pore structure, N2 absorption isotherms were measured at -196{degree}C under nearly 76cmHg using a commercially available full-automatic absorption measurement equipment. Based on the X-ray diffraction and TEM observation results on activated coals, the relation between the N2 absorption and pore structure was studied. The results are summarized as follows: (1) The yield and absorption ability of coals increase with a coal rank, (2) The specific surface area of coals reaches its peak at 800{degree}C in activation temperature regardless of a coal rank, and (3) The activation behavior of coals is dependent on a coal rank. 5 refs., 7 figs., 1 tab.

    In order to simplify the coke manufacturing process, a coke production mechanism in coal pyrolysis was discussed. Australian bituminous coal which can produce good coke was used for the discussion. At a temperature raising rate of 50{degree}C per minute, coal weight loss increases monotonously. However, in the case of 3{degree}C, the weight loss reaches a peak at a maximum ultimate temperature of about 550{degree}C. The reaction mechanism varies with the temperature raising rates, and in the case of 50{degree}C per minute, volatiles other than CO2 and propane increased. Weight loss of coal at 3{degree}C per minute was caused mainly by methane production at 550{degree}C or lower. When the temperature is raised to 600{degree}C, tar and CO2 increased, and so did the weight loss. Anisotropy was discerned in almost of all coke particles at 450{degree}C, and the anisotropy became remarkable with increase in the maximum ultimate temperature. Coke and volatiles were produced continuously at a temperature raising rate of 50{degree}C per minute, and at 3{degree}C per minute, the production of the coke and volatiles progressed stepwise as the temperature has risen. 7 refs., 6 figs.

    Change in depolymerization degree and coal structure was studied for depolymerization treatment of coal in various alcohol containing aqueous hydrogen peroxide. In experiment, the mixture of Yallourn coal, alcohol and aqueous hydrogen peroxide was agitated in nitrogen atmosphere of normal pressure at 70{degree}C for 12 hours. As the experimental result, the methanol solubility of only 5% of raw coal increased up to 35.2% by hydrogen peroxide treatment, while the yield of insoluble matters also decreased from 94% to 62%. Most of the gas produced during treatment was composed of inorganic gases such as CO and CO2, and its carbon loss was extremely decreased by adding alcohol. From the analytical result of carbon loss in hydrogen peroxide treatment, it was clarified that alkylation advances with introduction of alkyl group derived from alcohol into coal by hydrogen peroxide treatment under a coexistence of alcohol, and depolymerization reaction of coal itself is thus promoted by alcohol. 4 refs., 7 figs., 1 tab.

    With an objective to clarify the interactions between micropore structure of coal and solvent reagents, a sorption experiment was carried out under solvent saturated vapor pressure. Low-volatile bituminous coal, Pocahontas No. 3 coal, has the aromatic ring structure developed, and makes solvent more difficult to diffuse into coal, hence sorption amount is small. Methanol has permeated since its polarity is high. High-volatile bituminous coal, Illinois No. 6 coal, makes solvent penetrate easily, and the sorption amount was large with both of aromatic and polar solvents. Since brown coal, Beulah Zap coal, contains a large amount of oxygen, and hydrogen bonding is predominant, sorption amount of cyclohexane and benzene having no polarity is small. Methanol diffuses while releasing hydrogen bond due to its polarity, and its sorption amount is large. A double sorption model is available, which expresses the whole sorption amount as a sum of physical sorption amount and amount of permeation into coal. This model was applied when it explained successfully the sorption behavior of the solvents relative to coals, excepting some of the systems. However, also observed were such abnormal behavior as sorption impediment due to interactions between coal surface and solvents, and permeation impediment due to hydroxyl groups inside the coals. 1 ref., 10 figs., 2 tabs.

    The paper studied a possibility of estimating characteristics of coal liquefaction residue from liquefaction conditions in the case of fixing coal kind in the NEDOL process coal liquefaction PSU. Wyoming coal was used for the study, and the already proposed simplified liquefaction reaction models were used. Among material balances explained by the models, those of asphaltene, preasphaltene, THF insoluble matters are concerned with residue composition. Ash content is separately calculated from ash balance. Reaction velocity constants of simplified liquefaction reaction models which influence the residue composition were obtained by the multiple regression method from experimental results in the past. The estimation expression of residue viscosity was introduced from residue ash/composition. When the residue composition is estimated by the model from liquefaction conditions, and the residue viscosity is obtained using it, the higher the liquefaction temperature is, the higher the residue viscosity is. The result obtained well agreed the measuring result. The simplified liquefaction model of a certain coal kind has been established, and characteristics of residue can be estimated even at liquefaction conditions which have never been experienced before if there is a certain amount of the accumulated data on residue composition/characteristics. 4 refs., 4 figs., 4 tabs.

    A mobile network is constructed to enable users at remote locations (place dispatched to on business, working place, home) to access the PI (Power and Intelligence, which is a term used exclusively by Hokuriku Electric Power Company, Inc.) network by dialup connection, and problems and tasks in this connection are taken up. It is decided that access points be provided within the PI network now that the PI network itself is already in presence using exclusive lines and the security level will be lowered if the Internet is made use of. The PHS (Personal Handyphone System) is the communication medium chosen. For user acknowledgement upon dialup connection, a one-time password system is employed. As for the terminal equipment, subnote-size personal computers are to be used. The anomaly experienced during groupware line switchover, whose occurrence is confirmed in a field test, is believed to be remedied by incorporating an agent function into the PI network. The one-time password system costs much, dependent on the number of users. It is therefore necessary to study the use of some other systems. 1 fig., 5 tabs.

    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 disposal of tofu (bean curd) waste released from tofu production processes has become a serious problem. The present study is intended to provide a tofu waste processing method that can be useful in the fields of agriculture and stock raising. Tofu waste as released from a tofu producer contains about 80% water, but removal of the water will largely decrease its weight and facilitate its transportation and storage. Here, the feasibility of applying solar heat to the drying of tofu waste is investigated, and a small drying instrument is constructed and subjected to testing. The instrument comprises a rotating drum which collects heat and serves as drying container at the same time. From its heat collecting performance, the instrument is estimated to be able to dry 10kg of tofu waste each day down to a water content of less than 20% if the weather is fine. Its overall processing capacity can be increased by adding a separate heat collector to increase the heat collection capacity. 5 figs., 1 tab.

In addition to the data collection and site surveys made in Phase 1, conducted in Phase 2 were determination of sites for harbors, determination of a scenario on coal transportation from coal mines to harbors, optimization of the coal transportation system, social/economic assessment, and proposal on the optimum transportation system. The results of the simulation were as follows: It is the most advantageous to transport coal from coal deposit area to harbor by rail and from harbor to Paiton by barge weighed over 10,000 tons. Tanjung Api Api is the most advantageous as harbor. The production scale which is profitable became more than 15 million tons. The present coal price of PTBA is $25/t arriving Suralaya. The coal in this case is said to be 5500kcal/kg in quality, and the coal of the same quality to this is only profitable. 8 refs., 68 figs., 104 tabs.

    Coal demineralization mechanism and its optimum condition were studied by hydrothermal reaction between Ca(OH)2 and quartz as a coal demineralization model. In experiment, the mixture of powder quartz and Ca(OH)2 water slurry was subjected to reaction in an autoclave under spontaneous pressure at 175-340{degree}C. After dried in N2 gas atmosphere at 105{degree}C, the reaction product was analyzed by X-ray diffraction, thermo-balance and differential thermal analysis. In measurement of quartz conversion, the specimen was analyzed by X-ray diffraction after removal of bound water by heat treatment at 850{degree}C. The mixture of clean coal deashed by NaOH and a fixed amount of quartz was also used as specimen for experiment. As the experimental result, dicalcium silicate hydrate was mainly produced at 175{degree}C, and the product changed into xonotlite through tobermorite by longer treatment at higher temperature. For complete reaction of quartz, heat treatments for 7 and 5 hours at 300 and 400{degree}C were necessary, respectively. 2 refs., 2 figs., 2 tabs.

    Phase 1 survey in fiscal 1996 was conducted based on `Agreement on the comprehensive survey of a coal transportation system in South Sumatra` concluded between NEDO and the Ministry of Mine and Energy in Indonesia. In the survey, conducted were collection of data on coal fields and site surveys, collection of data on inland transportation and site surveys, collection of data on harbors and site surveys, and worked out were a simplified database and a coal transportation plan by optimization of the coal chain system. The area for survey is the periphery of the Musi River of South Sumatra. The results of the simulation by LP models were as follows: When the coal of Bukit Asam coal mine is $25/t in price, only coal of 5500Kcal/kg is profitable, and when $27/t in price, coal of 4500Kcal/kg also becomes profitable. This shows that if the coal is of good quality, it can pay arriving at Suralaya, independent of the distance of transportation. 47 figs., 63 tabs.

    Through the hydrogenolysis of Wandoan coal and Tanito Harum coal which are used for the NEDOL process, differences of liquefaction characteristics between them were found. The purpose of this study is to grasp these differences as differences of chemical structures of oil fractions. The compound type analysis was conducted for oil fractions obtained at varied reaction temperature for varied reaction time. Coal liquefaction characteristics of these coals were discussed by relating oil yields and chemical structures. For Tanito Harum coal, yields of gas and oil were considered to be lower than those for Wandoan coal, which reflected that the contents of partially hydrogenated hydroaromatics in oil fraction from the former were lower than those from the latter, and that the remarkable change of composition did not occur with the progress of the reaction. For both the coals, the remarkable changes in the average molecular weight of oil fraction were not observed with the progress of the reaction. While, the content of methane gradually increased with the progress of the reaction, which suggested that oil was gradually dealkylated. 5 figs.

    Mineral matter in coals is important in various senses for coal liquefaction. It is possible that the catalytic activity is affected by the interaction between catalyst and mineral matter. Iron-based catalyst forms pyrrhotite in the process of liquefaction, but the interaction between it and mineral matter is not known in detail. In this study, the interaction between mineral matter and catalyst and the selective reaction between them were investigated. Tanito Harum coal was used for this study. This coal contains a slight amount of siderite and jarosite besides pyrite as iron compounds. Liquefaction samples were obtained from the 1 t/d NEDOL process PSU. The solid deposits in the reactor mainly contained pyrrhotite and quartz. A slight amount of kaolinite was observed, and pyrite was little remained. It was found that the catalyst (pyrrhotite) often coexisted with quartz, clay and calcite. 8 figs., 2 tabs.

    To design the coal liquefaction reactor of large scale plant in future, it is important to understand characteristics of fluid dynamics within the coal liquefaction reactor. In this study, to measure the fluid dynamics of liquid phase within the coal liquefaction reactor operated under high temperature and high pressure coal liquefaction condition, neutron attenuating tracer (NAT) technique, one of the tracer test methods, was applied using 1 t/d coal treating PSU. The residence time of liquid phase within the reactor can be measured by utilizing property of neutron of being absorbed by materials. The tracer was injected at the inlets of first and third reactors, and the neutron was counted at each outlet. The concentration of tracer was derived from the discrete value, to determine the residence time distribution of liquid phase. The mean residence time of liquid phase in the single first reactor and in the total three reactors were prolonged under the severe operation conditions of liquefaction. The more severe the liquefaction operation condition was, the more active the mixing of liquid phase was in the first reactor. It was found that the progress of reaction was accelerated. 2 refs., 5 figs., 1 tab.

    For the removal and recycle of CO2, a global warming gas, utilization of photosynthesis by micro algae is investigated. Formed micro algae are decomposed into CO2, H2O and CH4 again, which does not result in the permanent fixation. For the effective utilization of these micro algae, creation of petroleum alternate energy was tried through the co-liquefaction of micro algae with coal. Were investigated influences of the reaction temperature during the co-liquefaction and influences of catalysts, such as Fe(CO)5-S, Ru(CO)12, and Mo(CO)6-S, which are effective for the coal liquefaction. Micro algae, such as chlorella, spirulina, and littorale, and Yallourn brown coal were tested. It was found that co-liquefaction of micro algae with coal can be successfully proceeded under the same conditions as the liquefaction of coal. The oil yield obtained from the co-liquefaction in the presence of Fe(CO)5-S, an effective catalyst for coal liquefaction, agreed appropriately with the arithmetical mean value from separate liquefaction of coal and micro algae. It was suggested that pyrrhotite, an active species for coal liquefaction, was sufficiently formed by increasing the addition of sulfur. 2 refs., 7 figs., 1 tab.

    The behavior and properties of associated bodies were studied through measurement of surface tension considering acetone-soluble fraction relatively light among various solvent extracts of coal. In experiment, the acetone-soluble fraction was extracted from the substances extracted from Upper Freeport coal as standard specimen using the mixed solvent of carbon disulfide (CS2) and N-methyl-2-pyrrolidinone (NMP), and it was dissolved into NMP after drying. Surface tension was measured by Wilhelmy method. The experimental results are as follows. Equilibrium surface tension is equal to the surface tension of pure solvent in a low concentration range of solution, and decreases with an increase in concentration approaching a fixed value at 0 in log concentration, nearly showing an S curve. Adsorption of species with non-polar aromatic ring of the acetone-soluble fraction on a solution surface probably decreases surface tension. Change with time in surface tension is observed which suggests fast initial reaction and slow subsequent reaction. 4 figs.

    With an objective to learn reactivity of coal at its surface, surfaces of oxidized coal samples were investigated. Miike coal was oxidized by using {sup 18}O2 in a closed loop system. As the reaction progresses, proportion of CO2 including isotopes increased rapidly as a result of oxidation of CO sites existing in the coal and the newly generated C{sup 18}O sites. The oxidizing reaction progressed via oxygen adsorbing sites generated near the surface, and oxygen containing groups. An FT-IR analysis estimated the depth of the oxidized layer to be 10{mu}m or less from particle surface. The oxidized coal was pulverized to see its surface condition. Functional groups introduced by the oxidation enter into the vicinity of the surface in a form to desorb as CO. CO2 is trapped in inner pores. The coal surface was observed by using an atomic force microscope. No observable openings in the pore structure were discerned on the surface before the oxidation, and the structure agrees with a closed pore model. Surface image oxidized in-situ by oxygen for one hour had slight roundness, which led to a supposition of structural change, and changes in the functional group and adsorption species. 7 refs., 5 figs.

    Conventionally, the thermal decomposition of coal is done by coke oven. Recently, a research is conducted to develop the process for quickly heating thermal decomposition of coal to produce the fuel gas and the tar with a higher yield. In this process, the heat required for thermal decomposition is supplied by indirectly heating the circulation gas. The circulation of a large quantity of high temperature gas accelerates the erosion-corrosion of the refractories and increases the heat loss through the furnace wall. This invention solves the problem. A particulate collector is installed at the outlet of the thermal decomposition furnace. The collected hot char is recycled to the high temperature gas generation furnace through a feeder as the heat source for the gasification reaction. The recycle quantity is arbitrarily set above the stoichiometric quantity to the oxidizing gas for combustion. With this way, the furnace temperature can be controlled to an arbitrary level, and the expansion of the service life of the refractories as well as the reduction of heat loss can be achieved. 4 figs.

    The test and survey on a next generation coal liquefying catalyst present a new proposal to raise catalytic activity in coal liquefaction, and perform demonstration experiments in a laboratory scale to search for possibility of developing a new coal liquefying catalyst from various viewpoints. To explain, discussions were given on the catalyst to perform the followings: liquefaction under extremely mild conditions by using ultra strong acids not limited only to metals; ion exchange method and swell carrying method to raise catalyst dispersion very highly, enhance the catalytic activity, and reduce the amount of catalyst to be used; mechanism of producing catalyst activating species to further enhance the activity of iron catalysts; and pursuit of morphological change in the activating species. The coal molecule scientific test and survey as the base for commercializing the coal liquefying technology performed the studies on the following items: pretreatment of coal that can realize reduction of coal liquefaction cost; configuration of the liquefaction reaction, liquefying catalysts, hydrocarbon gas generating mechanism, status of catalysts after liquefaction reaction, and reduction in gas purification cost by using gas separating membranes. Future possibilities were further searched through frank and constructive opinion exchanges among the committee members. (NEDO)

    A study is conducted on an energy supply infrastructure for introducing a cogeneration system into the Yumesu district, which is a key point for the development of Osaka City, so that environments suitable for the 21st century will be formed and sustained. In the study, plural heat supply systems are discussed for the district. Taken up also are the possible utilization of heat from the waste incineration plant to be constructed on the neighboring Maisu island and of hitherto-unexploited energy sources such as seawater and the sewage treatment plant whose construction is now under consideration. Findings are that every method under study achieves an energy-saving rate of 5% and that the introduction of an urban type power plant will obtain the best result marking an approximately 22% energy-saving rate when its exhaust heat is effectively utilized. The order remains the same when their environmental features are surveyed, with the urban type cogeneration system holding first place with a NOx reduction rate of 37.7%. When it comes to economy, however, the method of effectively utilizing the exhaust heat from cogeneration power plants installed at consumers' marks the best result, this attributed to the low cost of pipe laying in the district.

    Feasibility of commercialization is discussed of an environmentally friendly heat supply system for the above-named district. The research centers on the configuration and optimum dimensions of heat source equipment for a large-scale cogeneration-aided district heat supply system to be selected for introduction into the district. Discussion is made about the energy efficiency and environment preserving features of a system selected for employment. A study is then conducted on a plant consisting of two high-efficiency 4800kW gas turbine cogeneration systems and heat storing water tanks. Such when introduced will contribute to the levelling-off of urban power loads and to the enhancement of power peak cut through the utilization of cogeneration system-generated power and midnight power. When the exhaust heat from the cogeneration system is fully exploited, the system will achieve an energy saving effect approximately 9% higher than that exhibited by separately functioning heat source systems. Furthermore, CO2 will be reduced by 20% or more, NOx by 45% or more, and SOx by 46% or more, as compared with separately functioning heat source systems. The conclusive evaluation is that the above-selected system will sufficiently contribute to the preservation of environments. (NEDO)

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    Described herein is a system which uses a hydrogen-absorbing alloy to purify a hydrogen gas stream used as a coolant for power generator. Hydrogen in the stream containing impurities such as nitrogen can be selectively absorbed by sufficiently cooled hydrogen-absorbing alloy. Impurity gases concentrated in the alloy pores are released, and then the alloy is heated to release hydrogen. This purifies hydrogen to at least 99.99%. This system essentially consists of an hydrogen-absorbing unit, hot water production/supply system which circulates hot water of 80 to 90degC to release hydrogen out of the alloy, pretreatment unit, and temperature and pressure sensors. It is confirmed, by the test in which the system is connected to a commercial power generator of 600MW, that the system can be continuously operated to purify hydrogen to at least 99.9% for an extended period. 4 refs., 18 figs., 1 tab.

    Behavior of gas/liquid two-phase flow in tubes and behavior of air bubbles in liquid were investigated under the microgravity environment without convection by using the drop test facilities of the Japan Microgravity Center. To remove bubbles in the liquid under gravity, the strength of surface tension acting on the gas/liquid interface was made inhomogeneous. In this case, the moving velocity of bubbles on the gas/liquid interface was able to be raised up to the maximum of 2.4 mm/s. For the movement of bubbles in the horizontal direction under the condition of low relative velocity independent of the size of air bubbles in the duct, bubbles moving in the horizontal direction under 1g flowed almost linearly accompanying with the liquid flow. For the air bubble distribution in the bubble flow, where small bubbles flow in the vertical tubes, the fluid pattern of air bubble flow under 1g and {mu}g depended greatly on the initial condition of mixed bubbles. Fundamental data were obtained, as for the transportation and control of multicomponent bubbles, bubbles in the sound field, and bubbles in the liquid phase by magnetic force, and the fluid phenomena of bubbles in the subcool boiling region, a single bubble in the gradient electrical field, and bubbles in the tubes with small diameter. 47 refs., 97 figs., 8 tabs.

    It was investigated to use the expanded metal for form materials when the inspection gallery of a dam is constructed. The same method as a form method in tunnel lining concrete has been used until now. However, a concrete block or precast panel has been used for trial to shorten the process. Therefore, it was considered to use the expanded metal, which is lower in price and lighter in weight than the concrete block and which was also effectively used as form materials, as the form materials of an inspection gallery. A simple girder load test for bending rigidity that is the basic physical properties of materials was conducted first. Next, a form model was manufactured, and the displacement, strain, and hardening properties were tested. Concreting was performed using a full structural model to acquire the basic data such as construction performance. The way to analyze the form in this method was investigated, and quantitative data could be proposed on the design drawing and table and the cost reduction effect. The expanded metal is judged to be capable of being used for other structures as well as a dam inspection gallery. 21 figs., 2 tabs.

    Hokkaido and Tohoku District being about four times and two times, respectively as large as all Japan in average quantity of fuel, used for the air heating, the buildings there, as structured thermally insulated and aerially tightened, must be of a high quality environment with ventilation, aerial cleanness, etc. From the viewpoint that the heat pump, as able to utilize the low density energy,is appropriate exactly for the air heating in such a cold district, the heat pump was introduced in principle, categories and characteristics, problems of thermal source, and recent topics. With highness in temperature level of existing thermal source and lowness in that of air heating, the heat pump is thermodynamically explainable to be high in coefficient of performance (ratio of added quantity of heat on the high temperature side to the input power from the exterior). It is therefore the most important to maintain high quantity thermal sources, generally such as air, water, soil and waste water. Artificial waste heat is thermal source, the most noticeable as that in the cold region for the future. For example, local air conditioning system, utilizing waste heat from the subway operation, in Sapporo Station is taken notice of for its worldwidely first materialization. 21 refs., 21 figs., 6 tabs.

The current status of R and D of production and processing technology in each field is surveyed and the prospect of it is discussed. For the inorganic materials, metals and their composites, it is explained that very fine metal oxide particles, complex oxides, single crystals, whiskers, compounds with layer structure, metastable compounds, ion conductors and catalysts with high ability could be produced only by controlling the solvothermal reactions in atomic order. For the organic materials and their composites, surveyed results of the solvothermal technique using non-aqueous solutions are mainly provided.

    Windmills are one of the oldest prime movers and have been used for more than 700 years in Europe. The transition from low speed windmills for grain grinding and water pumping to high speed wind turbines for electric power generation had occurred at the end of 19{sup th} century. This paper, at first, reviews the windmill technologies and the researchers before 20th century. Then describes the back ground of how the wind power generator has existed and how the four pioneers developed their wind power generator. The historical developments of windmills to wind turbines in this century are studied focusing mainly on Danish activities. Then, the effort of the development of large wind turbine such as Smith-Putnum's first MW machine in U.S.A. and other mammoth machine concept are introduced. The new concept machines such as Savonius and Darrieus wind turbines in 1920s to 1930s are also explained. Finally, the novel technologies of wind turbine covering larger machines, variable speed generators, special wing sections for wind turbines, theoretical analysis method of wind turbine performance, offshore wind turbines, and wind turbine control technologies are stated.

    It is thought that iron-based catalysts for coal liquefaction exercise their catalytic activity by forming pyrrhotite (Fe(1-x)S). However, there are still a lot of unknown problems remained concerning the formation and agglomeration behaviors of pyrrhotite. These make a difficulty for improving the activity of iron-based catalysts. In this study, sulfiding behaviors of {alpha}-iron oxyhydroxide ({alpha}-FeOOH) and {gamma}-iron oxyhydroxide ({gamma}-FeOOH) were investigated to reveal the formation and agglomeration behaviors of pyrrhotite. It was found that pyrrhotite was easily converted from ferric oxyhydroxide catalysts having large specific surface areas at the sulfiding temperature below 250{degree}C, and fine crystallites of pyrrhotite were formed at the initial stage of sulfiding. Crystal growth of pyrrhotite at the sulfiding temperature over 350{degree}C depended on the catalyst forms. It was also found that smaller crystallites of pyrrhotite were formed from {gamma}-FeOOH than from {alpha}-FeOOH and amorphous iron oxyhydroxide. 5 refs., 7 figs., 1 tab.

    For high-efficiency coal gasification, investigations were given on effect of coal chars with different conversion rates on coal gasification reactivity. In coal gasification, reactivity of char after pyrolysis governs the efficiency. The reference char conversion in CO2 gasification of coal (weight loss) changes linearly in the initial stage of the reaction, but the reactivity declines as the end point is approached. Char surface area is as large as 400 m{sup 2}/g in the initial stage with the conversion at 20%, but it decreases in the final stage. This phenomenon relates closely with changes in pore size and crystalline structure. Change in the Raman value R which shows incompleteness of char graphite structure and amorphous carbon ratio suggests that an active portion with high reactivity is oxidized preferentially, and a portion with low reactivity remains finally. Minerals in coal are known to accelerate the gasification. However, their catalytic effect is related with chemical forms, and complex as they may change into inactive sulfides and silicates under severe reaction conditions. Change in forms of calcium compounds may also be involved in decline of the reactivity in the latter stage. 8 refs., 4 figs.

    With an objective to elucidate characteristics of oxygen addition to coal, and characteristics of solvent extraction by means of depolymerization, experiments were performed on oxygen oxidation and acid hydrolysis of brown coals. Coals used for the experiments are Morwell (MW), Yallourn (YL) , South Banko (SB) and Wyoming (WY) coals. Test samples were suspended in weak alkaline aqueous solution, and then oxygen was blown into them with pressure kept at atmospheric pressure. After a lapse of a predetermined time, the samples were cooled, and made as acidic as pH 1.3 in hydrochloric acid, followed by acid hydrolysis. Oxygen consumption increased with the reaction time, and with the MW coal, one mol oxygen reacted to 11 mols of coal. Spectral analysis on the YL and WY coal experiments revealed that aliphatic carbon combined with aromatic carbon or ether group has turned to peroxide, whose C-C or C-O bond was broken down as a result of acid hydrolysis of the peroxide, producing oxygen containing compounds. As a result of the depolymerization, the rate of extraction by using DMF, DMSO and methanol/THF mixed solvent increased to 90% or higher. Proportion of bond and cutting-off affects largely collapse of the cross-link structure. The carbon conversion to volatiles was at most 4%. 1 ref., 10 figs.

    To investigate the coal liquefaction characteristics, coal slurry samples were taken from the outlets of the reactors and slurry preheater of NEDOL process 1 t/d process supporting unit (PSU), and were analyzed. Tanito Harum coal was used for liquefaction, and the slurry was prepared with recycle solvent. Liquefaction was performed using synthetic iron sulfide catalyst at reaction temperatures, 450 and 465{degree}C. Solubility of various solid samples was examined against n-hexane, toluene, and tetrahydrofuran (THF). When considering the decrease of IMO (THF-insoluble and ash) as a characteristic of coal conversion reaction, around 20% at the outlet of the slurry preheater, around 70% within the first reactor, and several percents within the successive second and third reactors were converted against supplied coal. Increase of reaction temperature led to the increase of evaporation of oil fraction, which resulted in the decrease of actual slurry flow rate and in the increase of residence time. Thus, the conversion of coal was accelerated by the synergetic effect of temperature and time. Reaction rate constant of the coal liquefaction was around 2{times}10{sup -1} [min{sup -1}], which increased slightly with increasing the reaction temperature from 450 to 465{degree}C. 3 refs., 5 figs., 1 tab.

    Liquefaction of coal and biomass in supercritical water has been investigated, in which strong solubilization force of supercritical water against hydrocarbons is utilized. Free radicals are formed through the cleavage of covalent bonds in coal under the heating condition at around 400{degree}C during coal liquefaction. It is important to stabilize these unstable intermediate products by hydrogen transfer. On the other hand, hydrogen is not required for the liquefaction of biomass having higher H/C atomic ratio and oxygen content than those of coal. Co-liquefaction of coal and biomass was conducted using supercritical water, in which excess hydrogen from the liquefaction of biomass would be transferred to coal, resulting in the effective liquefaction of coal. Mixture of coal and cellulose was liquefied in supercritical water at 390{degree}C under the pressure of 25 MPa using a semi-continuous reactor, and the results were compared with those from the separate liquefaction of them. The co-liquefaction of coal and cellulose did not show any difference in the residue yield from the separate liquefaction of these, but led to the increased production of compounds with lower molecular weight. The liquefaction was completed in 15 minutes. 5 refs., 3 figs., 3 tabs.

    The computer aided coal structure construction system is proposed, and a computational construction example is presented. The coal structure construction engine of this system fabricates molecular structure by connecting fragments sequentially inputted through a user interface. The best structure candidate is determined using construction knowledge and partial energy evaluation every addition of one fragment, and this process is subsequently repeated. The structure evaluation engine analyzes the 3-D conformation candidate by molecular dynamics, and evaluates the conformation by determining the energy value of an optimum structure. As an example, this system was applied to construction of coal molecular structure based on the actual data of partial structure composed of 26 structures from 2l kinds of aromatic cluster structures, 27 bonds from 2 kinds of bridged bonds, and 16 groups from 2 kinds of terminal substitutional groups. As a result, this system could construct a superior structure according to expert knowledge from the viewpoint of energy. 6 refs., 5 figs., 2 tabs.

    An investigation was given on the relationship between methanol adsorbing behavior of reformed coal surface and oxygen containing functional groups in coal. Akabira bituminous coal was air-oxidized or Yallourn brown coal was decarbonated in oil as a reformation treatment. Both of the treated and untreated coals showed an adsorption heat curve of the Langmuir type. The Akabira coal had its oxygen content and the adsorption heat increased as a result of the air oxidizing reformation treatment. The Yallourn coal had its oxygen content and adsorption heat decreased as a result decarbonation reformation treatment. Oxygen containing functional groups act as strong adsorption sites for methanol, and the maximum adsorption amount depends on oxygen content in the coals. Since the coal surface is non-uniform in terms of energy, methanol is adsorbed first into sites with higher molar adsorption heat, and then into lower sites sequentially. Therefore, distribution of the molar adsorption heat can be derived from the relationship between adsorption amount and adsorption heat by changing methanol adsorption amount. The distribution of molar adsorption heat becomes broader when the oxygen content is high, and narrower when low. 2 refs., 2 figs.

    The NiMo sulfide supported on Ketjen Black (KB) was more effective and yielded lighter oil products containing light fractions with their boiling point below 300{degree}C during the two stage liquefaction combining low temperature and high temperature hydrogenation the conventional NiMo/alumina catalyst and FeS2 catalyst. Although the NiMo/alumina yielded increased oil products during the two stage liquefaction, the lighter oil fractions did not increase and the heavier fractions increased mainly. This suggests that the hydrogenation of aromatic rings and successive cleavage of the rings are necessary for producing the light oil, which is derived from the sufficient hydrogenation of aromatic rings using catalysts. For the two stage reaction with NiMo/KB catalyst, it was considered that sufficient hydrogen was directly transferred to coal molecules at the first stage of the low temperature reaction, which promoted the solubilization of coal and the successive hydrogenation at the high temperature reaction. Thus, high activity of the catalyst must be obtained. It is expected that further high quality distillates can be produced through the optimization of catalysts and solvents at the two stage reaction. 1 ref., 4 figs., 1 tab.

    In relation to considerations on composition of gas produced by coal gasification, the HYCOL hydrogen generation process data were analyzed. From the fact that CO concentration (Y) decreases linearly with CO2 concentration (X), element balance of gasification of reacted coal was used to introduce a reaction analysis equation. The equation includes a term of oxygen excess {Delta}(amount of oxygen consumed for combustion of CO and H2 in excess of the theoretical amount), derived by subtracting the stoichiometric oxygen amount used to gasify coal into CO and H2 from the consumed oxygen amount. The {Delta} can be used as a reference to oxygen utilization efficiency. An equation for the {Delta} was introduced. Also introduced was a term for steam decomposition amount derived by subtracting the generated steam from the supplied steam. These terms may be used as a clue to permeate into the gasifying reaction process. This suggestion was discussed by applying the terms to gas composition value during operation. According to the HYCOL analysis, when a gasification furnace is operated at higher than the reference oxygen amount, coal supply variation is directly reflected to the combustion reaction, making the {Delta} distribution larger. In an inverse case, unreacted carbon remains in the furnace due to oxygen shortage, and shift reaction may occur more easily even if oxygen/coal supply ratio varies. 6 figs., 1 ref.

    With an objective to learn mechanisms in low-rank coal reformation processes, change of properties on coal surface was discussed. Difficulty in handling low-rank coal is attributed to large intrinsic water content. Since it contains highly volatile components, it has a danger of spontaneous ignition. The hot water drying (HWD) method was used for reformation. Coal which has been dry-pulverized to a grain size of 1 mm or smaller was mixed with water to make slurry, heated in an autoclave, cooled, filtered, and dried in vacuum. The HWD applied to Loy Yang and Yallourn coals resulted in rapid rise in pressure starting from about 250{degree}C. Water content (ANA value) absorbed into the coal has decreased largely, with the surface made hydrophobic effectively due to high temperature and pressure. Hydroxyl group and carbonyl group contents in the coal have decreased largely with rising reformation treatment temperature (according to FT-IR measurement). Specific surface area of the original coal of the Loy Yang coal was 138 m{sup 2}/g, while it has decreased largely to 73 m{sup 2}/g when the reformation temperature was raised to 350{degree}C. This is because of volatile components dissolving from the coal as tar and blocking the surface pores. 2 refs., 4 figs.

    The purpose of this study is to prevent the deactivation of catalysts recycled in the 0.1 t/d bench scale unit (BSU). Catalysts recovered during reactions in the BSU and after reactions in the 5-liter autoclave were analyzed, to investigate the influences of the reaction condition on the property and activity of catalysts. Were used {gamma}-iron oxyhydroxide ({gamma}-FeOOH), {alpha}-iron oxyhydroxide ({alpha}-FeOOH), and natural pyrite (FeS2) as catalysts. At the S/Fe atomic ration of 1.2 under the BSU reaction condition, troilite was more easily formed from {gamma}-FeOOH compared with pyrite and {alpha}-FeOOH. As the reaction proceeded through the first, second, and third reactors, the crystal size increased, the pyrrhotite content decreased, and the troilite content increased. Deactivation due to the formation of troilite was irreversible. At the S/Fe of 3.0, however, both the formation of troilite and the crystal growth of pyrrhotite were not observed. It was found that the deactivation of catalysts can be remarkably suppressed. 5 refs., 6 figs., 1 tab.

    This is a proceedings of the papers made public in the 33rd (fiscal 1996) Coal Science Conference held by the Japan Institute of Energy. The number of the papers included is 82. The processes such as coal liquefaction, coal gasification and pyrolysis are largely influenced by reaction of the carbon compound in coal. However, coal, which is different in reaction characteristics depending on its producing area, is a comprehensive compound. Therefore, the trial has been made for clarifying the molecular structure and skeleton. In the sense, the following papers are taken notice of: Suzuki and others` Estimation for origin of coals by biomaker analysis; Sugimoto and others` Change of unit skeletons during the artificial coalification; Hirado and others` Study on the correlation between chemical and mineral composition of coal ashes; Okawa and others` Coal structure construction system with construction knowledge and partial energy evaluation; Kanbayashi and others` Analysis of the relationship between coal properties and liquefaction characteristics by using the coal database.

    Discussions were given on effects of heat treatment at relatively low temperatures as a pretreatment for coal liquefaction on coal swelling and hydrogenolysis reaction. Taiheiyo coal was heated to 200{degree}C for one hour as a pretreatment. The attempted heating methods consisted of four steps of rapid heating (6.7{degree}C/min)quenching (20{degree}C/min), rapid heating/natural cooling (0.7{degree}C/min), heating (1.0{degree}C/min)/quenching, and heating/natural cooling. The swelling treatment was composed of adding methanol benzene into heat treated coal, and leaving it at room temperature for 24 hours. The hydrogenolysis was carried out by using a tetralin solvent and at an initial hydrogen pressure of 20 kg/cm{sup 2} and a temperature of 350{degree}C and for a time of one hour. Hydrogenolysis conversion in the heat treated coal was found lower than that of the original coal because of generation of liquefaction inactive components due to thermal polymerization. When the heat treated coal is swollen by using the solvent, gas yield from the hydrogenolysis reaction decreased due to gas suppression effect, and the conversion was lower than that of the original coal. Heat treatment suggests densification of the coal structure. Swollen coal shows no conspicuous difference in the heat treatment methods against the hydrogenolysis due to the swelling effect. 3 refs., 5 figs., 1 tab.

    It is well known that the solubilization of coal can be accelerated by adding sulfur or hydrogen sulfide during direct liquefaction of difficult coals. From the studies of authors on the coal liquefaction under the conditions at rather low temperatures between 300 and 400{degree}C, liquefaction products with high quality can be obtained by suppressing the aromatization of naphthene rings, but it was a problem that the reaction rate is slow. For improving this point, results obtained by changing solvents have been reported. In this study, to accelerate the liquefaction reaction, Illinois No.6 coal was liquefied in tetralin at temperature range from 300 to 400{degree}C by adding a given amount of sulfur or hydrogen sulfide at the initial stage of liquefaction. The addition of sulfur or hydrogen sulfide provided an acceleration effect of liquefaction reaction at temperature range between 300 and 400{degree}C. The addition of sulfur or hydrogen sulfide at 400{degree}C increased the oil products. At 370 and 400{degree}C, the liquid yield by adding sulfur was slightly higher than that by adding hydrogen sulfide, unexpectedly. The effects of sulfur and hydrogen sulfide were reversed when increasing the hydrogen pressure. 5 figs., 1 tab.

    When considering merchandising scale of the coal liquefaction process, it is a preliminary condition that metal used for its catalyst is rich in resource volume, cheap in production cost, without pollution, and so forth, and application of cheap iron ore and ferrous compounds to disposable catalyst is desired. As liquefaction activity of the iron ore was hitherto improved by its micro crushing, its mechanical crush had a limit of about 2 {mu}m in mean particle diameter. However, together with recent crushing technique, crushers with high performance were developed, and then micro crushing by sub-micron became possible industri8ally even for iron ore. In this study, three kinds of Australian iron ores such as limonite of ferric hydroxide type iron ore, pyrite of ferrous sulfide type, and hematite of ferric oxide type were micro crushed to examine coal liquefaction activity and hydrogenation reaction activity of 1-methyl naphthalene (1-MN) and also relationship between properties and activity of catalyst for the latter before and after reaction. 11 refs., 8 figs., 5 tabs.

    Hydrogenolysis reaction of a model compound was studied using synthetic pyrite as catalyst to compare with a stabilized nickel catalyst. Benzyle phenyl ether was used as model compound, while naphthalene, tetralin or decalin as solvent. The model compound was hydrogenated at reaction temperatures of 325-459[degree]C and hydrogen pressures of 3-10 MPa for 0-60 min. As a result, unlike a stabilized nickel catalyst, the synthetic pyrite catalyst produced not only decomposed products as toluene and phenol but also a large amount of condensation products as di- and tribenzyle phenyl. It was thus suggested that a large amount of condensation products is produced in the initial stage of the reaction, and those are then converted to smaller decomposed products during the following reaction. Because of the weak hydrogenation activity of the synthetic pyrite, only a very small amount of hydrogenated products was obtained during the reaction within 15 min even at higher reaction temperatures and hydrogen pressures. 1 ref., 5 tabs.

    The paper reported the general training of the fiscal 1996 coal engineer training program supported by NEDO. In Japan, where natural resource is poor, it is important to transfer from its petroleum dependence energy structure to the system for new energy development and dispersed energy supply. Coal resource is distributed widely in the world and is expected to spread in the future as a main substitute for petroleum. Worldwide attention is much paid to coal supply/demand and environmental problems, but the situation surrounding coal is not necessarily favorable. Under these conditions, Japan is a prominent coal importing country and is on the world-top level in terms of coal utilization technology. Japan has heavy responsibility and needs to play a leading role in adjusting and solving various problems on coal both domestically and internationally. Under the circumstances, 7 persons who are engaged in the coal related business and expected to be in future (3 from the mining relation and 4 from electric power comapanies) participated in the training this fiscal year and received the top-level training in Japan and overseas. 20 figs., 3 tabs.

    The research was conducted jointly with Europe of a catalyst which enables clean combustion and NOx removal in polluted gas in combustion flue gas, etc. Reformation of mordenite and {beta}-zeolite was done by ion exchange, ion implantation, and membrane formation. A catalyst was searched for to obtain reducing agents, C5-C8 components, by decomposing light oil. Saponite, clay compound, showed by copper and silver ion exchanges approximately 50% of activity under 20,000h{sup -1}, C3H6 reducing agent, and without steam. The effect of the temperature of sintering on NOx selective reductionality of silver-carrying alumina catalyst was studied, and in sintering at 800degC, activity increased. When using conductive oxides like ruthenium oxide for electrolyte, NO decomposition selectivity increased. As to the functional layer carried above the Pd electrolyte, iron oxide and magnesium oxide increased NO decomposition selectivity. PdO and rare earth oxides forming compounds controlled variation of activity by dissociation/reoxidation of PdO. As to PdO/Gd203, the initial methane combustion activity was favorable, but there was seen deterioration with age. 271 refs., 281 figs., 58 tabs.

    A large-scale cogeneration system will be introduced into the air-front industrial complex in the Izumizawa area having large energy demand within the city of Chitose well blessed with natural environment. The system will utilize natural gas locally produced in the Tomakomai Yubarai area (the utilization produces 20% reduction effect of carbon dioxide emission even only from conversion from petroleum oil). At the same time, heat supply operation will be carried out meeting the heat demand in diversified consumer applications, such as air conditioning of ancillary facilities, hot water supply, hot bathing facilities, and snow melting. Business feasibility has been investigated and discussed. Discussions were given on gas engine, gas turbine, combined cycle, and steam jetting systems. Although the combined system was found most superior, other cases present no large difference excepting the turbine system. The system is a highly efficient energy saving facility (annually saving 3000 kiloliters of crude oil, worth for annual kerosene consumption by 1500 ordinary households in Hokkaido). It can largely reduce emission of carbon dioxide. Each case has large economic effect with the simply calculated number of years of return of investment being six to eight years. (NEDO)

    In energy utilization in the 'Kawasaki Zero Emission Industrial Complex', optimal regional heat supply systems were discussed. The discussion was made from the viewpoints of introduction of saving-type energies, new energies and renewable energies, and environment preservation performance. The coastal area in the Kawasaki ward is planned of developing an industrial complex with an area of 8.4 ha for operation of about twenty companies. In the assumption of heat demand, four companies only were taken up as the object of the discussion, who utilize heat supply from steam as process heat source for their factories. The total heat demand quantity and heat demand pattern used for the discussion were assumed by hearing and actual record submitted from each company. Optimal systems were discussed on heat supply systems utilizing steam produced by steel mills, with the discussion made on waste heat recovered steam in processes and steam extracted from thermal electric power plants in the steel mills. As a result of the discussion, heat supply utilizing the steel mill steam was found capable of being provided with much lower price level as the estimated unit price than general direct steam supply, leading to a judgement that the system has business feasibility.

    Studies are conducted for the development of now-unused kinds of fossil carbon resources, such as low rank coal and heavy gravity crude oil, into higher-value liquid fuel. In the preliminary treatment process, the fossil carbon resources are dried by use of supercritical carbon dioxide, when it is found that the resources are disintegrated and water is desorbed. In a low rank coal liquefaction process using the NiMo/KB (Kefjen Black) catalyst, more than 60% is converted into oil, which rate is improved by use of the dual-temperature liquefaction process. This catalyst may be recovered by separation utilizing specific gravity difference. As a low temperature gasification catalyst, the alkaline carbonate-carried carbon catalyst is very quick at the initial stage of reaction. The perovskite-carried alkaline carbonate catalyst is high in carbon oxidizing/activating efficiency at low temperatures. The silica film deposited on an alumina-coated support tube is excellent in selectivity and speed as a hydrogen separating film, and a carbonized polyimide film as a carbon dioxide separating film. For the supercritical phase adsorption/separation of chemicals not to be distilled easily, the NaY-type zeolite functions effectively. Pd/ZrO2 serving as a carbon monoxide conversion catalyst enables the recovery of more MeOH when Pd grains are smaller in diameter.

    Concerning the Sub-Arena being a part of the Osaka City Central Gymnasium which acted as the main meeting place of `Namihaya Athletics Meet` in 1997, its construction and results of predictive analyses were introduced in this paper. This area (Maishima isle) is covered with reclaimed soil until -6m in ground line (GL) and then with clay layer until -36m. The lower part from the above line is gravel layer, and the natural water level is GL-3m. Though the spherical shell roof assembled by PC can be found on the ground, the main body is a cylindrical earth self-retaining wall whose upper fringe is 0m in GL. The wall was composed of RC elements (thickness 1.2m) and made up a circle whose dia. was 52m by means of connection applying rigid joints. Though the bottom surface was GL-13m, the wall whose overall height was 39m was penetrated into gravel layer. Regarding predictive analyses for stress and deformation at the time of excavation, calculation factors were decided in accordance with guide-lines for basic design about underground connected wall by Obayashi-gumi Ltd. and the Japan Road Association. Deformation of the face of wall has been about 30mm at maximum at the most upper part whose value was about three times of analyzed value, and also increased about 5mm by the Hanshin earthquake. 3 refs., 12 figs.

    The Kansai Electric Power Co., Ltd., has developed a warm-water high-pressure washing machine utilizing midnight power. The warm-water high-pressure washing machine is a compact device, approximately 1.4m in height, approximately 1.4m in width, and 0.8m in depth, into which a rectangular water warmer (450 liter) and washing machine are integrated. Midnight power is utilized to heat water to 90{degree}C at night (22:00-08:00 next morning), and the hot water is mixed with cold water so that the washing may be done at 45{degree}C. The machine operates automatically (2-minute cleaning with cold water, 3-minute cleaning with warm water, and 1-minute rinsing with cold water, washing an automobile in a total of 6 minutes), which leads to the saving of water. It can wash 23 automobiles per day using 15{degree}C water. The running cost per day is a little more than 300 yen using midnight power, and is a little less than 200 yen under a business-oriented heat accumulation adjustment contract, the cost being lower than that demanded by city gas or heating oil. The newly developed machine is applicable not only to automobile washing at automobile maintenance factories or service stations but also to the washing of industrial wastes and restaurant kitchens, and the scope of application is expanding.

    Various technologies are under development toward the prevention of global warming and inhibition of CO2 emission. This report covers the recent result of an effort to use very fine alga for CO2 fixation in a NEDO-commissioned joint program participated in by the industry, government institutes, and universities. This is a project that aims to make use of solar energy through the intermediary of the photosynthetic activity of very fine alga for the fixation of the CO2 gas in presence in high concentration in exhaust gas and, at the same time, to extract useful substances out of the alga. More than 3000 kinds have already be collected, screened, isolated, and evaluated for their multiplication performance. A number of superior strains have been selected, including standard strains whose CO2 fixing capacity is higher than the predetermined level, those superb in resisting high temperature or tough in the given environment (flexible with varied culture conditions), and others that are excellent in yielding useful substances such as oil. A 200-liter class bioreactor of the airlift-plate type is now available, and full-scale experiments have been under way since April, 1997. 9 figs., 1 tab.

    Composite fiber-optic overhead ground wires (OPGWs) installed to the major power transmission lines are applied as the information transmission routs with large capacity. An effective system for the power line maintenance operation is able to be set up by using said OPGWs to collect and transmit various kinds of maintenance information on the power lines. However, since it is necessary for the whole equipment to meet the highest transmitting speed required by the system if a single transmission method is applied throughout the power lines for transmitting the maintenance information, the system loses its economy as a whole. In this paper, for the purpose of transmitting effectively the various maintenance information in power line maintenance information system using OPGWs, and considering the required transmission period as well as the types of the data occurrence, an optic fiber transmission system constituted hierarchically and composed of high-speed trunk line and low-speed local line is suggested. Especially, regarding the low-speed local lines, random transmission method shows the superior properties in the transmission efficiency and low power-consumption compared with the cyclic transmission method. 9 refs., 9 figs., 4 tabs.

    The paper collected/analyzed data on petroleum substitution energy in the Pacific region. In fiscal 1996, in addition to collection of the existing energy data, conducted were collection of energy data made retroactive from 1971, and time-series collection of the energy related expanded data including energy related production statistics/social statistics, energy consumption amount by industry, power generation facilities, oil production facilities, and environmental data. As to petroleum substitution energy, the paper took up new energy such as hydroelectric, nuclear, geothermal, photovoltaic, and wind power generation, and commercial-base renewable energy. As a result of the analysis, the supply of petroleum substitution energy in the whole Pacific region has been stable, 6.6% during 1980-1990, 7.4% in the first half of the 1990s, largely over the primary energy supply. The supply of nuclear power was overwhelmingly large, followed by hydroelectric energy and geothermal/new energy. 15 figs., 23 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.

    Effectiveness of livestock industry wastes and vegetable protein added to fish meal in fish farming is tested by feeding the Japanese flounder. 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.

    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.

    Hydrogen absorbing alloys have a number of useful functions, such as energy conversion, hydrogen storage and purification. As an application to separation and purification of hydrogen, we have developed a new hydrogen purification system by using a hydrogen absorbing alloy for generator cooling. For demonstration testing with an actual machine, a hydrogen recovery and purification device using 120kg of alloy was manufactured and installed on No.5 turbine-synchronous generator at Himeji No.2 power station. This device is designed to improve the purity of the hydrogen gas in generator containing impurities such as nitrogen and oxygen. The test results tell that the purity of the hydrogen gas in the generator can be enhanced from 98% to 99.9% and maintained at this level under continuous operation. An application of the hydrogen purification system is expected to decrease the generator`s windage loss, resulting higher generator efficiency. 2 refs., 18 figs.

    Mycelia of a fungus Mortierella alpina 1S-4 and the mutants derived from it are new and rich sources of C20 polyunsaturated fatty acids (PUFAs) of pharmacologically and dietary importance. M. alpina 1S-4 produces a unique triacylglycerol with high n-6 PUFA content. The mycelial content of arachidonic acid reaches 274 mg/g dry mycelia (4.3 g/L) on cultivation of the fungus in a medium containing glucose and yeast extract. The value accounts nearly 70 % of the total fatty acids in the extracted oil. Mutants defective in {delta}5 desaturase are potent produces of dihomo-{gamma}-linolenic acid (4.1 g/L). A {delta}12 desaturase-defective-mutant produces an oil containing only n-9 PUFAs. The mycelial Mead acid content is 141 mg/g dry mycelia (1.9 g/L). An oil rich in n-3 PUFAs can be produced by the same mutant when grown in a medium containing linseed oil. The content of total n-3 PUFAs (i.e.,{alpha}-linolenic acid+8, 11, 14, 17-cis-icosa-tetraenoic acid+5, 8, 11, 14, 17-cis-icosapentaenoic acid) is nearly 50% in total mycelial fatty acid. The enzyme systems for the biosynthesis of PUFAs in the Mortierella fungi is also discussed. 33 refs., 7 figs., 1 tab.

    The local space air conditioning using air curtain was theoretically analyzed. The conditions, where the Coanda effect appeared in the case of local heating, and the temperature characteristics in the eddy generated by the effect were clarified. The force generated by the pressure difference between upper and lower parts of entrained air as well as the buoyancy is applied to the warm plane jet. When the trajectory of the warm jet was theoretically estimated, the critical condition where the jet attaches to the floor was identified as K{sub c}=1.0k{sub p}{sup -0.96} (where K=Ar(H{sub s}/h){sup 3/2}, k{sub p}: center line velocity constant, Ar: Archimedes number, and H{sub s}/h: offset ratio). The critical condition where the attached warm jet goes up was expressed by K>1.39/((2.35+1.25h/H{sub s})k{sub p}{sup 1/2}). The temperature in the eddy region is maintained by the heat, which is supplied with the warm jet collided against the floor due to the Coanda effect and divided into the eddy region. The temperature characteristics within the eddy, which are theoretically derived, were approximated by the following equation, {delta}{theta}{sub c}/{delta}{theta}{sub o}{approx} 0.90(H{sub s}/(k{sub p}h)){sup -1/2} (where {delta}{theta}{sub c} is temperature difference between cavity and room air, and {delta}{theta}{sub o} is temperature difference between outlet and room air). 6 refs., 9 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)

    Enzymatic and chemical methods were combined and methods were developed for synthesizing mucin type sugar chains and glycopeptides. The influence of sugar chain positions and structures on glycoconjugate stereo structures and physiological activities was analyzed, and glycopeptide structural activities and glycoconjugate remodelling were studied. To create an industrial advantage in a glycoprotein production system by use of zooblasts, sugar chain structure control through sugar transfase occurrence control was studied. For the production of man-adaptive sugar chains using yeast, new yeast variations were subjected to molecular breeding, and tested for the resultant improvement on productivity. 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)

    Microorganisms are cultivated industrially in a great quantity to fix CO2 at efficiency higher than that of photosynthesis in natural world to develop technologies to re-utilize them as resources. This paper describes achievements in fiscal 1998. Existing strain samples of photosynthesized bacteria and micro-algae were screened to continue discussions on optimal culture conditions, and evaluation on properties. Genes that provide Chlorella with antibiotic resistance were introduced to have performed evaluation on function manifestation, and acquired enzymatic genes of unsaturated {omega} 3. Using green algae as the object, reduction in the processing time has resulted in acquiring a large number of fused cell colonies. Discussions were given on conditions to breed photosynthesized bacteria and fix CO2. Structural analyses were performed on CA protein as an enzyme related to take CO2 into living organisms, and on genes. Developments were carried out on a photosynthesizing bio-reactor and useful substance producing technologies on a continual basis. A 200-liter scale light collection type bio-reactor improved the fixing capacity by 30% in Chlorellas by changing the culture medium. The direct light receiving panel type bio-reactor can utilize even scattered light, with its fixing capacity per installation area exceeding the target. Fundamental data were acquired with Chlorellas on utilizing feeds, fertilizers and building materials. (NEDO)

    Curie point flash pyrolysis (FP) reactivity was studied experimentally using three kinds of coals with different coal ranks such as Yallourn brown coal, Tanitoharum sub-bituminous coal and Wandoan sub-bituminous coal. Experiment was performed using a curie point pyrolyzer in carrier gas of 20ml/min in gas flow rate at 450, 590 and 740{degree}C for 5sec. The experimental results were as follows. Each gas component obviously increased at 450-590{degree}C, however, C4-C6 gases drastically decreased at 590-740{degree}C accompanying reduction of the whole gas quantity. All of each polar component remarkably increased at 450-590{degree}C. Yallourn brown coal with high Owt%, in particular, contained a large amount of alkyl-hydroxybenzene group. The amount of cresol of all of three coal specimens also increased at 740{degree}C. It was thus suggested that this is coal constituent molecules derived from cutting of methylene-ether bridged bond by higher-temperature FP. 8 refs., 5 figs., 3 tabs.

    For developing coal liquefaction processes, it is an important problem to improve the light oil yield with increased oil yield. It was previously reported that distillate mainly containing lighter fraction can be produced with high oil yield by reducing the iron/sulfur catalyst addition in slurry, by recycling gas in the process operation, by utilizing these effects, and by using heavy oil as recycling solvent. In this study, the maximum distillate yield of Victorian brown coal was investigated through continuous liquefaction using a bench scale unit. In addition, operation conditions for obtaining sufficient oil yield were investigated under the reduced catalyst addition into one-third. Consequently, it was confirmed that the maximum content of lighter fraction in distillate product was obtained with reduced catalyst addition by using heavy oil as recycling solvent, by adopting new catalyst, and by utilizing effects of CLB recycling and gas recycling in maximum. It was also revealed that lighter distillate can be produced compared with the oil product obtained by recycling conventional solvent. 3 refs., 6 figs., 2 tabs.

    In the wide range from brown coal to anthracite, an investigation was made of effects of heat treatment on physical/chemical properties and of coal rank dependence. For the experiment, 12 kinds of coal samples were used, and for heat treatment, the fluidized bed heated by the electric furnace and the infrared-ray gold image furnace were used. To examine characteristics of the heat-treated coal char, conducted were oxygen gasification, TPD measurement, XRD measurement, alkali metal measurement, and pore distribution measurement. The following were obtained from the experiment. The gasification reaction rate of the char heat-treated in the temperature range between 900{degree}C to 1700{degree}C decreases with a rise of the temperature of heat treatment, and the degree of decrease in the rate depends on coal rank. The order of gasification rate between coal ranks depends on the temperature of heat treatment, and the lower the heat treatment temperature is, the more largely the gasification rate is influenced by catalysis of mineral matters included in the coal. As causes of the decrease in gasification rate associated with the rise in temperature of heat treatment, indicated were release of alkali metal having catalysis and decrease of active sites by carbonaceous crystallinity. 6 figs.

    The reactivity of oxygen methylated coal was studied to control hydrogen bond in bituminous coal liquefaction and intermolecular cohesion such as van der Waals force. In experiment, crushed and dried Illinois coal of 100mesh or less was used as specimen, and oxygen methylated coal was prepared by Liotta`s method using tetrabutylammonium halide. Coal liquefaction was conducted in an electromagnetic agitation autoclave using tetralin solvent under initial hydrogen pressure of 100kg/cm{sup 2} while heating. The molecular weight distribution of the products obtained was measured by gel permeation chromatography (GPC) analysis. The experimental results are as follows. The effect of intermolecular cohesion in bituminous coal on the reactivity is mainly derived from decomposing reaction from preasphaltene to oil. Yields of oil fraction by methylation increase corresponding to release of intermolecular cohesion. Since the thermal release is promoted with temperature rise, the difference in yield due to different treatments decreases. 5 refs., 3 figs., 1 tab.

    For the improvement of economy, coliquefaction of coal, tar sand bitumen and plastic was performed under low hydrogen pressure, to investigate the influence of interaction among these on the liquefaction characteristics. For comparison, coliquefaction was also performed under the hydrogen pressure same as the NEDOL process. In addition, for clarifying its reaction mechanism, coliquefaction of dibenzyl and plastic was performed as a model experiment, to illustrate the distribution of products and composition of oil, and to discuss the interaction between dibenzyl and various plastics, and between various plastics. Under direct coal liquefaction conditions, coprocessing of Tanito Harum coal, Athabasca tar sand and plastic was carried out under low hydrogen pressure with an autoclave. The observed value of oil yield was higher than the calculated value based on the values from separate liquefaction of coal and plastic, which suggested the interaction between coal and the mixed plastic. The results of coliquefaction of coal, tar sand bitumen and plastic could be explained from the obtained oil yield and its composition by the coliquefaction of dibenzyl and plastic. 2 refs., 3 tabs.

    In terms of coal conversion reaction, the behavior of bituminous coal heated beyond a glass transition point was examined on the basis of pyrolyzed products, and the effect of an increase in proton mobility on promotion of coal decomposition was evaluated. In experiment, after Illinois bituminous coal specimen was heated up to a specific temperature in N2 or He gas flow at a rate of 5K/min, the specimen was directly transferred to a pyrolyzer for instantaneous pyrolysis. As the experimental result, the glass transition temperature of the Illinois coal specimen was calculated to be 589K from a differential scanning calorimetry (DSC) profile. From the pyrolysis result of the Illinois coal specimen heated up to 623K, the char yield decreased by 3kg as compared with that of the original coal, while the tar yield increased by 4kg up to 27kg per 100kg of the original coal. This tar increase was larger than that of cooled coal. These results suggested that the donation of hydrogen radicals to coal fragments is improved with an increase in proton mobility. 4 refs., 4 figs., 1 tab.

    Process solvent was hydrogenated in the brown coal liquefaction, to investigate the influence of it on the prethermal treatment and liquefaction. Consequently, it was found that the n-hexane soluble (HS) yield was improved. In this study, capacity of hydrogen transfer from solvent during prethermal treatment and effects of catalyst were investigated. Since prethermal treatment in oil was effective for improving the oil yield in the presence of hydrogen/catalyst or high hydrogen-donor solvent, influence of hydrogen-donor performance of solvent or addition of catalyst on the hydrogenation behavior of coal and the characteristics of products during prethermal treatment were investigated in relation to successive liquefaction results. As a result, it was found that the increase of HS yield was due to the acceleration of conversion of THF-insoluble using high hydrogen-donor solvent and/or by adding catalyst. It was also found that the use of high hydrogen-donor solvent and highly active catalyst at the stage of prethermal treatment before the successive liquefaction was effective for improving the HS yield, i.e., liquefied oil yield. 2 refs., 5 figs., 1 tab.

    On BTX production process from low-temperature tar obtained by pyrolysis of coal, the effect of exchanged metallic species and reaction temperature were studied using metallic ion-exchanged Y-zeolite as catalyst. In experiment, three kinds of coals with different produced tar structures such as Taiheiyo and PSOC-830 sub-bituminous coals and Loy Yang brown coal were used. Y-zeolite ion-exchanged with metal chloride aqueous solution was used as catalyst. Zn{sup 2+}, Ni{sup 2+} and In{sup 3+} were used as metal ions to be exchanged. The experiment was conducted by heating a pyrolysis section up to 600{degree}C for one hour after preheating a contact reforming section up to a certain proper temperature. As a result, the Ni system catalyst was effective for BTX production from aromatic-abundant tar, while the Zn system one from lower aromatic tar. In general, relatively high yields of toluene and xylene were obtained at lower temperature, while those of benzene at higher temperature. 4 figs., 1 tab.

    The paper reported the energy situation in Thailand, the present and future status of coal supply/demand, the present situation of environmental policy and air pollution prevention policy and problems concerning coal and the measures for solution, and a possibility of Japan`s cooperation. In Thailand, the total coal supply amount in 1992 is 16.079 million tons, which is 9.1% of all the primary energy supply amount. The country produces only a few amount of anthracite and subbituminous coal beside brown coal. The domestic coal equals brown coal, the production of which was 15.335 million tons in 1992, 13.9% of all the primary energy demand. Concerning brown coal, 79.7% of all the brown coal supply are for electric power use, and others for industrial use such as the cement industry. The remaining reserve in developed areas is 151.4 billion tons, and the proven reserve in undeveloped areas 756 million tons. The demand for import coal was 11.25 million tons in 1996, and is expected to be 201.73 million tons in 2000. The paper pointed out some problems arising from coal production and spread of coal utilization, and described measures to solve the problems and fields where there are possibilities of Japan`s cooperation. 36 refs., 44 figs., 73 tabs.

    Discussions were made using model compounds to identify hydrogen transfer and liquefaction mechanism in coal liquefaction reactions. The test specimen is behzylphenyl ether (BPE), and the binary solvents are prepared from naphthalene, tetralin and decalin. The BPE was hydrocracked under the presence of synthetic pyrite catalyst. This catalyst has low hydrocracking resolution, producing very little hydrogenated decomposition products, but a considerably large amount of condensation products consisted of decomposition products and those consisted of decomposition products and the solvents. In a system with presence of tetralin or naphthalene, the higher the aromaticity of the solvents, the more decomposition products, particularly phenol, were produced, and the less dibenzyl phenol: a condensation product consisted of the decomposition products. However, increase was observed in benzyl tetralin or benzyl naphthalene which is a condensation product consisted of the solvent tetralin or naphthalene and benzyl group. Production of benzyl phenol was less in a solvent system with high aromaticity. 3 refs., 3 figs.

    Focusing on the present status and future of coal demand in Central/South American countries and the coal trade between Central/South American countries and the U.S., the paper described the present status and future of coal demand there and the effects on Japan. Export of Colombian coal will amount to approximately 30-35 million tons in 2000. Venezuelan coal 10-20 million tons. The U.S. imported good-quality general coal low in sulfur content, 3.08 tons from Columbia and 1.39 tons from Venezuela. Coal export from the U.S. to Central/South America was mostly of raw material coal, 5 million tons in 1993 and 5.39 million tons in 1994. General coal was 180,000 tons. The U.S. has no plans of increasing US coal export to Central/South America. But it is safely predicted that Columbia and Venezuela will increase coal export to Europe in the future. It will bring about decrease in export of US coal to Europe, which connects with increasing pressure for the coal trade amount of Japan. 21 figs., 47 tabs.

    Japan-China joint coal survey was made through seismic prospecting by Japanese group and drilling prospecting by Chinese group. Mei-Xian mine property includes coal seams of the Jurassic period, and is covered with the quaternary period stratum without any coal seam. The base of the quaternary period stratum exists at depth of 50-400m, while the coal seams at depth of 300-700m. Among 11 existing seams, the 1st and 5th seams are main objects for prospecting. The 5th seam of 0.2-8.96m (2.95m in average) thick is the most expected important one, distributing all over the mine property. The 5th seam also has branch seams spreading over 2.5km from east to west and 1.2km from south to north in the center part of the mine property. The 1st seam of 0-8.62m (2.90m in average) thick is most thick in the south part of the mine property. The theoretical amount of coal deposits in the whole coal seam is estimated to be nearly 290,000,000t by Chinese group (nearly 50% of it in the 5th seam). That is also estimated to be nearly 346,000,000t by Japanese group (155,000,000t in the 5th seam). Both 1st and 5th seams are composed of sub-bituminous coal. (NEDO)

    In this paper, a method for executing a stable management of wastewater treatment process is examined by using a wastewater treatment process simulator with the facilities adopting intermittently aerated 2-tank activated sludge process as the object. The following results are obtained from said examination. Based on a fact that the treatment efficiency is influenced greatly by the comparatively miner parts of the process in biological nitrogen and phosphorus removal, a wastewater treatment process simulator, by which the intrinsic process flow, restricting conditions and behaviors of controlling system of each facility can be dealt with, is developed by using object-directional model. As the results of this development, not only the effects approximate to those of actual process can be obtained, but also the trial error and alternation of process flow can be realized in a short time. The serious influence of disappearance of dissolvable organic substance in flow-adjusting tank upon the deterioration of biological phosphorus removal is clarified by the results of the simulation based on the investigation of flowing-in water quality. 12 refs., 13 figs., 4 tabs.

    Large scale and effective utilization of renewable energy including hydroelectric power, photovoltaic power, and wind power which are abundant on the earth can contribute to the solution of global environmental issues as well as the release of energy demand and supply. Hydrogen can be produced from the renewable energy, and is converted, transferred and stored if necessary. Such hydrogen can be used in various fields for power generation, fuel for transport, and city gas. In order to establish the technology by which worldwide energy network can be introduced for wide range of fields, conceptual design of a total system has been conducted, and elemental core technologies have been developed. Conceptual design of a practical scale system (total system) including a wide range from production of hydrogen to its utilization has been conducted, and its constitution has been illustrated. In addition, the energy balance and cost of hydrogen have been calculated and analyzed as a trial. Hydrogen production technology, transport and storage technology, and hydrogen utilization technology are introduced as individual elemental technologies.

In polymerization of fine pyrrole grains under the existence of fine latex grains, production of fiber polypyrrole is remarkable, and fiber growth from latex surfaces was confirmed. The obtained thin bacteriorhodopsin film shows a photoelectric response, and as the AFM observation result, it is mainly composed of violet single-layer electrodeposited films. The wetting rise of acrylic monomer at the interface between solid and liquid is largely dependent on viscosity. The oil droplet size distribution of O/W emulsion is narrower than that in ground experiment, and is close to a normal distribution. Easy imaging of products was achieved by tracing cytochrome crystals with change in turbidity. The crystallization phase diagram of black mold acid protease A, and basic data in crystallization process were obtained. (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.

    A survey was carried out to make available the information base that can collect, put into order and provide quickly and accurately the energy related information based on global environment problems in the Pacific Ocean region. Fiscal 1998 has performed a substituting energy demand and supply analysis in the Pacific Ocean region by adding the 1996 data, in addition to collection of the normal energy data. For the purpose of analyzing the petroleum substituting energy demand and supply in the Pacific Ocean region, data were collected from 17 countries for fiscal 1997 and the quarterly data for 1998. Retroactive data collection was also continued. The growth rate of primary energy supply in the Pacific Ocean region is 1.8% in average in the 1980's, and 3.8% in the 1990's. In contrast, the growth rate of petroleum substituting energies is 6.4% in the 80's and 6.2% in the former half of the 90's, being far higher than the growth rate of the primary energy supply. The share of the petroleum substituting energies accounting for in the primary energy supply has increased from 6.7% in 1980 to 12.1% in 1996. As the breakdown, nuclear power accounts for overwhelmingly large, followed by geothermal energy and new energies. (NEDO)

    The paper described the results of the FY 1999 research on the fouling by marine aufwuchs. The survey is aimed at searching the nature world for active substances for biological antifouling. The fouling mechanism in the ocean is as follows. The adsorption of organisms called the conditioning film first occurs on the surface, and next, bacteria and diatom around the surface form biofilm and cover. After that, biological fouling by large aufwuchs occurs. Therefore, the control of biofilm formation was regarded as most important, and with this as a guidepost, the search was conducted. Using biofilm anti-formation activity and periphytic bacteria anti-growth activity as guideposts, some compounds were searched for. Being aimed at Porifera, in particular, new compounds were isolated from it. Since few of other organisms attaches on the surface of sponge, there is a great possibility of Porifera's producing any anti-fouling substances. Further, it is thought that symbiotic microorganisms of sponge (40% of the total weight) produce various biologically active substances. Synthetic phenethyl amine derivatives were also studied.

The WE-NET project aims at development of the total system for hydrogen production, transport, storage and utilization, and construction of the earth-friendly innovative global clean energy network integrating elemental technologies. Since the standpoint is different between latent resource supplying countries and technology supplying countries, the WE-NET project should be constantly promoted under international understanding and cooperation. The committee distributed the annual summary report prepared by NEDO to overseas organizations, and made positive PR activities in the 11th World Conference and others. The committee made the evaluation on the improvement effect of air pollution by introducing a hydrogen vehicle in combination with Stanford University, and preparation of PR video tapes for hydrogen energy. Preliminary arrangement of Internet home pages, establishment of a long-term vision for international cooperation, and proposal toward the practical WE-NET are also made. 9 figs., 13 tabs.

    To know the applicability of passive solar energy in Bolivia, weather data were prepared for the air conditioning load calculation. As a representative city in the plateau, foot and plain, El Alto, Cochabamba and Santa Cruz were selected, respectively. Based on the observation data in the airport`s weather stations, data were prepared on the atmospheric temperature, humidity, wind direction, wind velocity and cloudiness. Because there existed no data on the quantity of solar radiation, its daily integrated quantity was calculated by regression from the daily mean cloudiness recorded in the data which were collected in 1978 by the meteorological observatories belonging to both Ministry of Transport, and Ministry of Posts and Telecommunications. More adaptable than the linear regression formula, the quadratic one gave correlation coefficients convergent in the region from 0.5 to 0.9 in most of the months. The daily integrated quantity of solar radiation was then divided by Collares model into its time-by-time quantities, which were further divided by Udagawa method into both their direct component and diffused component. Though the summer cloudiness is high in both El Alto and Cochabamba, the quantity of solar radiation is larger than that of the winter, which is judged attributable to the high solar angle of elevation. The wind is strong in El Alto. 5 refs., 7 figs., 3 tabs.

    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.

    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.

    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)

    Axially chiral biaryls compounds are of importance not only as chiral ligands for asymmetric reactions but also as biologically active natural products, e. g., korupensamine, michellamine and vancomycin. (Arene) chromium complex exists in two enantiomeric forms based on a planar chirality. Axially chiral biaryls were stereoselectively prepared by palladium(0)-catalyzed cross-coupling of (aryl halide)Cr(CO){sub 3} complexes with arylboronic acids. This method was applied for the total synthesis of antimaralial agent korupensamine A, naphthyltetrahydro-isoquinoline alkaloid. Furthermore, chiral 1,2-diols and diamines are important compounds for asymmetric reactions. These enantionerically pure 1,2-diols and 1,2-diamines were stereoselectively prepared by pinacol coupling of planar chiral chromium complexes of benzaldehydes and benzaldimines with samarium iodide. Moreover, non-biaryl axial compounds, N,N-dialkyl 2,6-disubstituted benzamides were synthesized in enantiomerically pure form utilizing planar chiral arene chromium complex. (author)

    This report provides the development of new exploration technology using elastic waves, such as reflection seismic survey, VSP, and seismic tomography, for precisely characterizing subsurface fractures in geothermal reservoirs. In order to investigate and improve the effective data acquisition and analysis methods for detecting a fault type of fractures, an experiment of a seismic tomography method was conducted using wells drilled in the Ogiri geothermal field, Aira-gun, Kagoshima Prefecture. An experiment of propagation characteristics of piezo type underground seismic source in the volcanic field was also conducted as a trend survey of underground seismic sources. The fracture type in the model field was systematically analyzed by measuring the core samples obtained in the demonstration test field through remanence measurement, fluid inclusion measurement, and zircon measurement using test equipment, and by analyzing results obtained from cores and results of seismic tomography obtained from the wells. Based on these results, the effectiveness and practical application of exploration methods using elastic waves were investigated. 80 refs., 250 figs., 49 tabs.

    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.

    An investigation was conducted with the aim of elucidating the foundations for effective utilization of environmental pollutants or unused resources which are likely to be causal substances of environmental pollutants, as resources, using biotechnology. Composting of agricultural waste, production of microbial mycelium proteins and microbial fermentation materials were suggested as main examples of effective utilization of unused resources by microorganisms. Selection of active microorganisms in the livestock waste, clarification of the mechanism of action and the establishment of treatment conditions are essential to new developments in this field. In the field of marine products industry, it was pointed out that the recycling of waste using microorganisms and enzyme treatment is the most promising approach to the effective utilization of resources. In the field of food industry, applications as the culture media for mushrooms, for enzyme production and for the production of physiologically active materials as well as fuel were clarified. Was also pointed out the significance of studies on the microorganisms and enzymes in resources containing cellulose, hemicellulose and lignin, and the waste from these resources, lignocellulose. Were also proposed the composting of household waste, methane fermentation, and fermentative production of organic acid and hydrogen from waste. Possibility and significance of fermentative production of organic acid from sewage sludge were suggested. 314 refs., 46 figs., 33 tabs.

    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.

    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)

    It is intended to use a space closed by an air film (vortex region) as a utilization space, and air-condition the space locally. The discussed method utilizes a phenomenon that plane jet in a semi-closed space deposits on a floor as a result of the Coanda effect. The Coanda effect, however, may not appear with warm jet during room heating. A discussion was given to derive the limit of the effect, and elucidated the temperature characteristics of the vortex region when the space was with and without obstacles. When the effect does not develop, the buoyancy of the warm jet in the horizontal direction supersedes static pressure drop generated by attracting flow rate of the flow. The experiment proposes the limiting condition of the jet deposition as K = Ar (Hs/h) [sup 3/2] (where Ar is an Archimedian number, Hs is a vertical distance from the floor to the center of the air outlet, and h is the air outlet width). The distance for the warm jet to deposit on the floor is constant irrespective of the air blow-out velocity and the blow-out temperature difference, where a relation of Ls/Hs [approx] 1.56 may be established. The temperature in the vortex region where there are no obstacles on the floor is a function of height and width of the air outlet, and that for where obstacles exist is expressed as a function of the obstacle installing distance and the outlet width. 3 refs., 13 figs., 1 tab.

    An internet was originally called Advanced Research Projects Agency Network (ARPANET), and it was mainly a military related network. In 1980s, by an assistance of the National Science Foundation (NSF) the military related parts were cut off, and then the existing networks were taken in one after another, and consequently a basis of the present internet was made. After that the NSF has come to manage a nucleus network, and in addition the further various existing networks were absorbed, and subsequently an internet has been formally started in 1989. Though in the petroleum industry through the oversea business offices of each enterprise an information collection is being performed, in addition to a system so far, a construction of the system to be able to get without omission and simply a political information being transmitted rapidly through the internet from the foreign governments, furthermore the publicized informations of the academic societies and the public service organizations, and so forth will be necessary to be done.

    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.

    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.

    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)

    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)

    In order to reduce environmental load, such as suppression of dioxin generation in Kagoshima Prefecture having a large number of small cities, towns and villages, discussions were given on business feasibility of introducing a high-efficiency industrial wastes power generation system intended for the whole Kagoshima prefectural area. The discussions performed investigations on quantity of wastes generation by districts and kinds and the present treatment conditions, system designs, and optimization of business operation systems. Loads given to the environment in association with the system installation were also investigated (SOx, NOx and CO2 emission, and water quality contamination). The system incinerates and treats RDF, waste plastics and combustible wastes in a gasification melting furnace, and amount of dioxin in the waste gas and ash is reduced to below the regulation values. Quantity of heat obtained from the combustion is turned into high-temperature and high-pressure steam, which is utilized for power generation. As a result of the discussions on business profitability, the industrial wastes power generation system intended for the whole prefectural area was found sufficiently realizable if installed by the public organization and operated by private business organization. However, such mechanism as PFI is thought difficult in the range anticipated at the present time. (NEDO)

    Improvement in efficiency and profitability of hydrogenation reaction of heavy hydrocarbon resources is the most important matter to be done. In this study, coprocessing of coal and heavy oil vacuum residue was conducted using syngas-water as a hydrogen source. For the investigation of effect of the reaction temperature during the coprocessing of Wandoan coal and Arabian heavy vacuum residue using Fe(CO)5 as a catalyst, the conversion, 66.0% was obtained at 425{degree}C. For the investigation of effect of reaction time, the yield of light fractions further increased during the two stage reaction at 400{degree}C for 60 minutes and at 425{degree}C for 60 minutes. Finally, almost 100% of THF-soluble matter was obtained through the reaction using 2 mmol of Fe(CO)5 catalyst at 400{degree}C for 60 minutes, and hydrogenation of heavy oil was proceeded simultaneously. When comparing coprocessing reactions using three kinds of hydrogen sources, i.e., hydrogen, CO-water, and syngas-water, the conversion yield and oil yield obtained by using syngas-water were similar to those obtained by using hydrogen, which demonstrated the effectiveness of syngas-water. 2 refs., 2 figs., 2 tabs.

    It was previously reported that the tritium tracer method is useful for the quantitative consideration of hydrogen behavior in coal during coal liquefaction reaction. Tetralin is excellent hydrogen donating solvent, and is considered as one of the model compounds of coal. In this study, effects of H2S and H2O on the hydrogen exchange reaction between tetralin and gaseous hydrogen labeled by tritium were investigated. It was suggested that the conversion of tetralin and the hydrogen exchange reaction between gaseous hydrogen and tetralin proceed through the radical reaction mechanism with a tetralyl radical as an intermediate product. When H2S existed in this reaction, the hydrogen exchange yield increased drastically without changing the conversion yield. This suggested that the hydrogen exchange reaction proceeds even in the reaction where radical does not give any effect. In the case of H2O addition, the conversion yield and hydrogen exchange rate decreased into a half or one-third. It was suggested that H2O inhibited the formation process of tetralyl radical. 6 refs., 4 figs.

    Reactions of various model compounds were investigated using synthetic pyrites for coal liquefaction. In this study, successive changes of the catalysts were investigated from the reactions of model compounds by using three different synthetic pyrites with the lapse of time after production. Benzyl phenyl ether, dibenzyl, and n-octylbenzene were used as model compounds. Reactions were conducted in an autoclave, into which sample, catalyst, decalin as solvent, and initial hydrogen pressure 10 MPa were charged. The autoclave was held at 450 or 475{degree}C of reaction temperature for 1 hour. The catalyst with a shorter lapse of time after production acted to hydrogen transfer, and inhibited the formation of condensation products due to the stabilization of decomposed fragment. It also acted to isomerization of materials by cutting alkyl side chains. When adding sulfur to the catalyst with longer lapse of time after production under these reaction conditions, it inhibited the formation of condensation products for the reaction of benzyl phenyl ether. However, it did not provide the effect for the reaction of n-octylbenzene. 5 refs., 3 figs.

    The effect of char addition on sintering behavior of flying slag particles in an entrained-bed coal gasifier was examined using four kinds of amorphous water-quenched slag obtained at the pilot plant of HYCOL. This plant was designed to gasify 50 tons of coal per day. The sintering temperatures of the four slags without char were all approximately 800{degree}C. However, Taiheiyo coal slag did not sinter at 900{degree}C when the char added. It was considered that the char collected by the cyclon was a mixture of soot and unburned coal particles and the soot prevented the slag from sintering. Therefore, the effect of soot on sintering behavior was clarified using carbon black as soot. SEM and EDX analyses showed that very small soot particles acted as a dispersant in the slag. 12 refs., 13 figs., 2 tabs.

    In consideration of the coal situation in the Asia/Pacific region, a study was made of effects of the expansion of coal trade by IPP on supply/demand of general coal in Asia. When aggregating increases in demand of general coal for electric power use in ten Asian counties, they will be an increase of 130.75 million tons in 2005 over 1997. Fifty nine percent of it is equivalent to the increase by IPP and exceeds the demand expanded by electric utilities operators. Further, a possibility is predicted of contracts and coal quality being different from until now. However, there will be a lot of cases in which plans of constructing power plants in Asia are not so developed as expected except Japan, Korea and Taiwan, and also the effect of the currency crisis starting in Thailand largely affects. In terms of the coal supply, countries which export general coal are only China and Indonesia. Indonesian coal is expanding its production and export rapidly and remarkably. The environmental control in Asia has been tightening, and the fuel selected by IPP is mainly coal rather than natural gas. 40 refs., 94 figs., 179 tabs.

    This report summarizes the research result on development of new coal exploration technology. For a high-precision and high-resolution reflective seismic exploration system, R and D was made on the exploration technology of several meter in resolution for medium-depth (800m) coal deposits under a lake of 2m deep. As a result, the high-frequency and high-power source (150-200Hz in dominant frequency, 700-800m in penetrability) and the high-frequency and high sensitivity receiver (10-1000Hz in frequency band, 35V/PA in sensitivity) were developed successfully, and the positioning system was improved. The final evaluation of these elementary technologies was carried out through demonstration tests, resulting in satisfactory results. For a high-efficiency trial drilling system, the in-bore trouble prevention system for measurement, processing and analysis of drilling data (drilling length, drilling rate, revolution, bit load, torque) and drilling mud data (charge water pressure, charge/discharge water, density, pH, viscosity) was constructed. The outlook for low-cost measurement and a safety during drilling was thus obtained. (NEDO)

    In view of the prospective demand for coal in China and of the current state of transportation, a development plan is formulated for Tangkou Mining Area (of model mines) for the purpose of realizing efficient exploitation of coal. The infrastructures for coal transportation are complete in this area, and delivery of coal is easy from this area to the coal demanding regions. Although coal seams are quite deep in the ground, the important ones contain rich reserves. Exploitation is carried out under a vertical shaft scheme, in which pits extend horizontally at the level of 950m below the sea surface. As for production, an annual yield of 3-million ton is predicted thanks to two compositely mechanized coal faces. Coal is won by the monolayer side hole method in the case of seams not thicker than 4.0m, and by the caved stope method in the case not thinner than 4.0m. Employed for the mines are 1077 people. Operation days are 300, efficiency 15t/man/shift. The annual sale in total is expected to be worth 759-million 534.6-thousand yuan. To be required for the construction will be 1.2-billion yuan for mines and 0.2-billion yuan for coal dressing facilities, or 1.4-billion yuan in all, and the figures indicate that the plan is economically promising. 43 figs., 119 tabs.

    As a WE-NET subtask, a study has been conducted of the solid polyelectrolyte water electrolysis method by which higher efficiency and lower cost hydrogen production is expected than in the conventional hydrogen production method. Production methods of electrode, electrolyte, etc. were studied. In the electroless plating method, the manufacturing process of membrane-electrode assemblies was realized in a large area of 2500 cm{sup 2} by the porous-surfaced method by studying manufacturing conditions for slurry membrane/membrane assembly/electroless plating processes. In the hot-press method, the refining degree and dispersibility of iridium dioxide powder were studied to improve characteristics of anode catalyst. A method was developed to form polyelectrolyte coatings homogeneously on the surface of electrode layer catalytic powder, and a large area of 2500 cm{sup 2} was realized. Beside the performance test using large single cells, FS was conducted to discuss optimum operating conditions and optimum structures of plants. Both methods indicated the performance exceeding the energy conversion efficiency of 90%, a WE-NET target, at current density of 1A/cm{sup 2} and electrolysis temperature of 80degC. A key was found to a bench-scale development (electrode area of 2500 cm{sup 2}, about 5 layers) to be planned in fiscal 1998. 136 figs., 50 tabs.

    The paper described the results of the development of technology of low temperature materials in the fiscal 1997 WE-NET. Using experimental equipment for materials under the atmosphere of liquid hydrogen, an experiment on mechanical characteristics under the liquid hydrogen atmosphere (20K) was conducted of the base materials of candidate steels (SUS304L, SUS316L and A5083). In material evaluation experiments (tension/fracture toughness/fracture tests), characteristic behaviors of the materials were shown which are different from those shown in the environment of liquid He (4k), etc. Even if the amount of {delta} ferrite in the metal welded of the stainless steel is small, approximately 1%, the degradation of low temperature toughness occurred. Welded joints of stainless steel by submerged arc welding and MAG welding were in now way inferior in tension characteristic to those by TIG welding, but were inferior in toughness ranging from room temperature to extremely low temperature. As to aluminum alloys, materials excellent in extremely-low temperature toughness were able to be found. Under the low temperature hydrogen gas atmosphere, the lower the strain rate is, the higher the hydrogen brittleness susceptibility is around 220K (extremely large hydrogen brittleness temperature) (SUS304L). In the hydrogen gas of 100 atm, hydrogen invades the material at 100degC, but does not at 77k. 38 refs., 173 figs., 48 tabs.

    The efforts aim to meet consumers' needs for products that will prevent lifestyle diseases or the like. For this purpose, substances answering the purpose are extracted from Hokkaido-produced agricultural and aquatic biomasses, and prepared for testing. Researches are conducted on how they behave in the enzyme, cell, and biological systems, and active substances are isolated and identified. In relation to the aquatic biomass, a technology is established of extracting and separating DHA (docosahexaenoic acid), EPA (eicosapentaenoic acid), taurine, etc., which are multivalent unsaturated fatty acids effective in preventing lifestyle diseases, from the unused parts of the squid. In relation to the agricultural biomass, antimicrobial active substances are extracted and separated from small fruit plants such as the chicory. Long-keeping foods are tentatively produced by the addition of dried powder of the chicory root tuber. In the elucidation of various biological regulatory substances contained in the Hokkaido-produced biomasses, they are tested for their abilities to resist microbes and active oxygen. Furthermore, verification tests are conducted by administering the substances to the senescence-accelerated mouse (SAM). (NEDO)

    In relation with drilling of deep seated geothermal resources, R and D has been performed on high-strength cement slurry for high temperature use, as an elementary technology for drilling. This paper summarizes the achievements in fiscal 2000. In the R and D on the high-strength cement slurry for high temperature use, experimental discussions were given on stability of the strength over 24 hours and 28 days, and the basic compositions were determined on cement, silica, and micro-alumina. In order to give considerations on the results of each test, crystal structures were specified and analyzed by using XRD/EDAX, wherein selection was made on slurry that has crystal structure suitable for GemSTONE concept. Furthermore, based on that composition, experimental studies have been carried out, including optimization of mixing materials used, mixing ratio of hollow balloons to increase the strength, and comparisons in the cases when the diameter thereof is changed, and when mixing is executed. With regard to effects of the case when blast furnace slag is added to increase the initial strength, tests were carried out, in which the composition was given fine adjustment within the range of the GemCRETE theory, from which the intended result was obtained.

    The capacity and performance of the existing system that recovers the overall heating and cooling exhaust heat completely into a seasonal storage tank and the system that discharges the exhaust heat slightly to the outside and recovers it partially were compared and investigated. The system uses a central single-duct discharge system as an air-conditioning system. A heat pump and a flat-plate solar collector installed on the roof of a building are used as the heat source. The seasonal storage tank in the ground just under the building is a cylindrical water tank of 5 m deep with the concrete used as body. The upper surface of a storage tank is heat-insulated by a stylo-platform of 200 mm, and the lower side surface by a stylo-platform of 100 mm. Calculation when the difference in temperature used in a seasonal storage tank is set to 35{degree}C and 25{degree}C was performed for the system that has two control methods. The overall exhaust heat recovery system is almost the same in energy performance as the partial exhaust heat recovery system. The partial exhaust heat recovery system is more advantageous on the economic side. 4 refs., 6 figs., 3 tabs.

    Bioconsortia are microbial composites composing of more than two kinds of microorganisms with special functions. To utilize their advanced functions, some techniques have been developed for analyzing their functions and interactions, and for identification, separation and incubation of the constituent microbial groups. In FY 1997, an investigation was made on technology trends, domestic researchers, and research topics related to bioconsortia. To manage and promote the progress of research at the National Institute of Bioscience and Human-Technology where the centralized management of this project is conducted, meetings are held once a month to examine the progress at the institute, in which reports are made and discussions are held on how each research item is progressing. In addition, meetings of the committee to promote research are held every other month to consider and examine measures required for promoting the research. Re-entrustment of research has been made on two subjects, i.e., `Studies on biological significance of symbiotic microorganisms` by Prof. Ishikawa of the University of Tokyo, and `Study on the relationship between the biosynthesis of useful terpenic materials of plant origin and the differentiation of plant tissues, and their effective production by plant cell cultures` by Prof. Inoue of Gifu Pharmaceutical University. 27 refs., 13 figs., 1 tab.

    The expression, bioburden, is used by many organizations such as WHO and ISO in the field of pharmaceutical related products and is defined as the number and kind of microorganisms which exist as suspended bacteria attached to the object or in an area under the condition close to the nature. In case when this word is used as a nonexperimental element, in the area of production environment, the measurement of the number and kind of microorganisms related there becomes the main concern and in case when the word is used as the element of experiment, test and research, it is utilized in sterilization, sterile filtration, etc. as microorganism load. This article is a general review with occasional insertion of the author`s own views on the concept and utilization concerning bioburdens in the production environment of pharmaceutical related products (medicine, tool for medical treatment, cosmetics, etc.) and explanation is given on the concept and meaning of bioburden grasping of the current state of bioburden and its analysis, general idea to be borne in mind in measuring bioburden, bioburden and its background, importance of bioburden and measures to cope with internationalization. 15 refs., 1 fig., 5 tabs.

    The paper described the fiscal 1997 result of the study of scenarios for introducing hydrogen to the urban area. In the case of studying it in London, it was found that hythane (mixture of hydrogen into town gas) was effective, but in the case of doing in Tokyo, it was found that the scenario was undesirable because of the increasing infracost. Accordingly, another scenario was studied. It was assessed from the aspects of environmental advantages, infracosts, and potential advantageous values in urban areas associated with hydrogen utilization (hydrogen premium). It is most effective to use hydrogen as a fuel of transportation means from the aspect of environmental merits as the decrease in external cost. In Tokyo, the dependence upon electric power is large, and therefore it is attractive to introduce highly efficient fuel cells which enable the dispersed cogeneration using hydrogen. The value of hydrogen is determined by the avoidance of environmentally influential substances and the surplus generated output by fuel cells (substitution for the existing natural gas). When the high external cost can be assumed, the value of hydrogen becomes large. The paper also considered the arrangement of infrastructures in Tokyo. 187 refs., 14 figs., 18 tabs.

    This report describes the fiscal 1998 result on development of genome informatics technology. As comparative analysis technique of genes, the combination of electrophoresis and PCR was used. For improvement of the throughput and reproducibility of the technique, module- shuffling primers were used, and the multi(96)-arrayed capillary fragment analyzer was devised. The system detecting SNPs rapidly was also developed successfully. As analysis technology of DNA sequence by use of triple- stranded DNA formation, study was made on construction of long cDNA libraries, selective subtraction of specific sequences from libraries, and the basic technology of homologous cloning. Study was also made on each reaction step of IGCR technique for fast analysis, and specifications of a fluorescence transfer monitor. As modeling technique of genetic sequence information, the simulation model was developed for gene expression regulatory networks during muscle differentiation, and feedback regulation of period genes. Such support systems as transcription factor prediction and gene regulatory network inference were developed from existing data. (NEDO)

    This R and D project is aimed at stable production of high-quality, important machine members, which are difficult to sufficiently achieve the required properties by a single material, by carburization while minimizing use of expensive alloy metals, where high-temperature carburizing time is reduced by a plasma-aided system to save energy, and, at the same time, the conventional oil-hardening system is replaced by a He gas cooling/recycling system to solve the environmental problems involved in the former. The exhaust gases released from the plasma-aided system are adequately treated to prevent the problems caused thereby. The conditions of the plasma itself and treated surfaces are sensed in-situ, and the data are fed back to the process controlling system, to keep the treated object stable and high in quality, while minimizing energy consumption. The FY 1998 efforts were directed to studies on methods for sensing the plasma and treated surfaces, and specifications of a mini-plant for the demonstration tests, and to collection of characteristic data for development of some new products to be produced.

    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)

    As a part of the WE-NET project, the basic technology necessary for large-scale hydrogen liquefaction facilities was studied. The process efficiency over 40% was targeted, and the plant cost was evaluated by complexity of the liquefaction process. Since the recycling line consumes a large amount of gas, the cost and supply method of gas were evaluated. The refrigerant cost for open inspection and leakage refilling was also estimated. Since the stage of centrifugal compressors decreases with an increase in average gas molecular weight followed by increase in compression ratio, the compressor was evaluated by average molecular weight. The expansion turbine was also evaluated by the same way. The heat exchanger was evaluated by volumetric flow balance. Since the liquefaction line uses combustible hydrogen, the safety of the recycling line was evaluated by combustibility of hydrogen. Five liquefaction processes such as hydrogen Claude, helium Brayton, neon Brayton, mixed refrigerant and nelium Brayton cycles were compared. Based on the relative evaluation result, the former two cycles were selected for the future precise study. 14 figs., 19 tabs.

    This survey clarifies the present situation of the solar heat utilization technology mostly for industrial use, makes a concrete concept of solar heat utilization clear, and extracts items of the technology development and evaluates sociality, economical efficiency, etc. It aims at working out a program for the future technology development. The following proposals were made: 1) technology development program; 2) simulation soft development program; 3) experimental field of the solar heat utilization technology. In 1), concepts of technology development are 'medical use boiling pasteurization,' 'temperature increase in the metal surface treatment process,' 'water purification using photo-catalyst,' 'distributed small power system,' and 'waste water treatment using bio-technology.' In 2), cost reduction is needed for commercialization/merchandising of technology, and therefore, the development of simulation software is studied. In 3), as the experimental field from commercial/residential use system to industrial use system, an large-scale and systematical experimental field is proposed where all that can be substituted for by solar energy among the energies required for the urban function are used. By this, the solar heat utilization system gets accustomed to the people, increases the reliability, and clearly leads to the course to the next stage of the R and D. (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.

    Described herein are the FY 1998 results of the activities for development of extraction and production technologies for the deep-seated geothermal resources, which are expected to contribute to increased geothermal power generation capacity. The program for the PTSD logging technology connects the S probe to PT probe, to simultaneously measure temperature, pressure and volumetric flow, producing the data of good quality even in a high temperature environment over 327 degrees C. Thus, possibility of the commercial system is confirmed. The D probe also produces a density calibration curve showing very good linearity, and operates normally in a high temperature environment of 406 degrees C. The program for the PTC monitoring technology conducts the field tests at Larderello, Italy, to confirm the sampler functions in a high temperature environment. The program for the tracer monitoring technology extracts promising tracers stable at high temperature from those for the liquid, vapor and liquid/vapor mixed phases. Silica is observed to be massively dissolved at 400 to 1,000mg/kg in the fluid under deep geothermal conditions. Scale precipitation rate is minimal for the first 21 days, but increases linearly with time thereafter. The experiments are also conducted for formation and prevention of the Fe-Si-based scales during the flushing period. (NEDO)

    With an objective to develop geothermal resources, research and development has been performed on the production technologies for the deep-seated geothermal resources, such as pressure, temperature, flow speed and density (PTSD) logging technologies. This paper summarizes the achievements in fiscal 1999. In the actual well test on the developed D-probe, it was verified that the probe operates normally under high temperature environment (342 degrees C) which exceeds the measurement limit of conductive cables (315 degrees C). In developing the PTC monitoring technology, the downhole sampler was improved, and a test was performed in the actual hole in the Hijiori area in Yamagata Prefecture. As a result, collection of hot water of about 900 mL has become possible. In developing the high-temperature tracer monitoring technology, simulation was performed keeping in mind charging the tracer into the Hijiori geothermal area, whereas specifications for charging and collecting the tracer were determined. In developing the scale monitoring technology, experiments were carried out on the fluid systems under deep geothermal conditions by using scale forming devices, by which it was indicated that silica is the important scale constituent.

    At COP3 in 1997, an agreement was made to the innovative technical development/promotion by international cooperation, and the promotion of transfer of environmental technology to developing countries. Under the agreement, a feasibility study of international cooperation was made, and especially a study was conducted of the utilization/development of solar energy by the innovative solar thermochemical process. The main reason for global warming is emissions of a large amount of CO2 caused by the direct combustion of fossil fuels. Therefore, a CO2 recycle system taken up in the study enables a more substantial decline in CO2 emission (kg/kWh) per unit generation than the conventional thermal power system by composing solar methanol or solar dimethyl ether using fossil fuels including coal, water, CO2, etc. as raw materials and using solar energy as heat source, and by using this as fuel (solar fuel). CO2 can be reduced by 13% to 14% by substituting solar methanol or solar dimethyl ether produced from petroleum/methane equivalent-mol mixed raw materials for the equivalent mol coal and natural gas of the thermal power plant (CO2 recovery is not necessary). 34 refs., 47 figs., 34 tabs.

    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.

    For the purpose of effectively utilizing medium and high temperature geothermal water type geothermal resource as unused resource, the paper described the development of the binary cycle power generation which generates electric power by heat-exchanging thermal energy of geothermal water with secondary medium using heat exchanger. The development was commenced at the same time as the fiscal 1974 Sunshine Project started, succeeding in constructing/operating a 1000kW class 2-system pilot plant by up to fiscal 1978. After that, the element research for the development of a 10MW demonstrative plant was commenced in fiscal 1979. For the purpose of effectively using geothermal water sleeping as unused resource which is weak in spontaneous welling, the development of the well submersible motor driven downhole pump was also commenced in fiscal 1983, and the development of the pump of demonstrative size (200t/h, 380m, 400kW, 200degC) was finished in fiscal 1992. In the Houhi Sugawara area, a typical medium/high temperature geothermal resource area, reservoirs were assessed starting fiscal 1985 to confirm the amount of geothermal resource by drilling test wells and by production/injection tests.

    In relation to the conceptual design of the total system of hydrogen utilization, the paper described the fiscal 1997 result. The study was conducted having no relation with the conventionally assumed large-scaled/centralized utilization based on the hydrogen produced from renewable energy. Costs of coal gasification and natural gas reforming hydrogen production become lower than that of the hydrogen from the hydroelectric power utilization overseas. However, the processing of CO2 fixation is at a developmental stage, and it is required to see and watch it in the future including the time of the commercialization and economical efficiency. Further, the hydrogen recovered from industrial complexes has a possibility of becoming sources for the distributed utilization (hydrogen diesels, fuel cells, and hydrogen cars). The pipeline transportation of hydrogen gas via the East China Sea from China can be expected. The CO2 emission unit requirement of the power system by liquid hydrogen transportation/ammonia transportation is equal to that of the renewable energy power system and low in environmental loads. The unit requirement of the methanol transportation power generation, in which coal is used, is the same as that of the LNG fueled power generation and inferior in environmental characteristics. The combination with the CO2 fixation processing technology is indispensable. 25 refs., 53 figs., 60 tabs.

    In the fiscal 1995 study, items were searched which are keys to the design of a liquid hydrogen tanker of a capacity of 200,000m{sup 3}. Among those, the basic concepts were summarized which are necessary for the design of a liquid hydrogen tanker in terms of safety, and the extraporation of the existing low temperature technology into the large liquid hydrogen tank was studied. When adopting safety conditions of IGC Code applied to LNG to the liquid hydrogen tanker, it is necessary to limit the discharge amount of hydrogen to 3 kg/s. When considering safety at fire, for keeping safety of the same level as that of the LNG tanker, it is not appropriate to adopt the conventional vacuum insulation liquid hydrogen tank. In the fiscal 1995 study, 7 kinds of concept of the insulation structure were assumed, and it was concluded that BOR of 0.04-0.23/d was obtained. Also in fiscal 1996, the large liquid hydrogen tank was studied. For insulation of the large liquid hydrogen tank, the structure is most promising where AEROSIL bag or homogeneous AEROSIL is substituted for a forming heat insulating material of 4 design, but further study is needed for selection of the optimum heat insulating structure. 9 figs., 6 tabs.

    For the purpose of the effective international research cooperation, the paper surveyed in fiscal 1997 the effective use technology of saturated hydrocarbon, technology against the surplus aromatic hydrocarbon and technology of high grade treatment of petroleum coke. In the survey of the effective use technology of saturated hydrocarbon, trends of FT synthesis technology and DME synthesis technology were studied as trends of technology to produce synthetic gas, and a project was proposed for technical development of using natural gas as liquid fuel in Japan. In the survey of technology against the surplus aromatic hydrocarbon, studied were the benzene law regulation and the supply/demand trend of aromatic hydrocarbon, process to reduce production of aromatic hydrocarbon as much as possible, process to reduce aromatics of the produced petroleum products, and process to effectively use aromatic hydrocarbon as chemical raw material. In the survey of high grade treatment of petroleum coke, studied were a possibility of using HS petroleum coke in the DIOS method, iron bath gasification, and copper bath gasification technology. 108 refs., 146 figs., 103 tabs.

    test in Tokyo: Hideo MAEDA (Bureau of Social Welfare and Public Health, Tokyo Metropolitan Government). 2. Contact investigation of a tuberculosis outbreak: Kenichi MIYAMOTO (Takaido Community Health Center). We have experienced a TB outbreak in integrated junior and senior high school in Tokyo. Index patient was a student with persistent respiratory symptoms for six months before diagnosis of sputum smear-positive TB. Public health center started contact investigation immediately. QFT-positive rates were high in close contacts, especially in classmates. Additionally, a student outside of contact investigation was diagnosed as TB and considered to be infected from the first patient by VNTR analysis. Therefore, public health center expanded QFT-tests to all students and teachers in this school. Finally, 9 students and 2 teachers in this school were diagnosed as sputum smear-negative TB by contact investigation. 3. Utilization of molecular epidemiological procedure in contact investigation in Kyoto City: Masahiro ITO (Public Health Center of Kyoto City) Molecular epidemiological procedure using VNTR analysis has been used for contact investigation of tuberculosis since January 2011 in Kyoto City. One hundred forty four strains of Mycobacterium tuberculosis from patients with tuberculosis were investigated and 130 strains were fully analyzed. Fourteen clusters were found and the number of strains included in the cluster was ranged from two to 11. Epidemiological relationship between patients in one cluster was found, however, significant relationship in another clusters was not demonstrated. It was suggested that VNTR analysis is useful for molecular epidemiological analysis of tuberculosis. 4.
