    Pretreatment of brown coal in oil was conducted using 1-methyl naphthalene or mixture of tetralin and 1-methyl naphthalene as solvent at temperatures ranging from 300 to 430{degree}C under nitrogen atmosphere. Effects of the solvent properties on the structural change of oxygen-functional groups (OFG) and coal liquefaction were investigated by means of quantitative analysis of OFG and solid state {sup 13}C-NMR measurement. When hydrogen transfer from solvent was insufficient, it was suggested that brown coal molecules loose their hydrogen to be aromatized. While, at lower temperatures ranging from 300 to 350{degree}C, hydrogen contained in brown coal molecules was consumed for the stabilization of pyrolytic radicals, and the deterioration of liquefaction was not observed. When hydrogen transfer from solvent was insufficient at higher temperatures above 400{degree}C in nitrogen atmosphere during pretreatment in oil, crosslinking like benzofuran type was formed by dehydration condensation of hydroxyl group in brown coal, to deteriorate the liquefaction, remarkably. The addition of donor solvent like tetralin decreased the formation of crosslinking like benzofuran type, which suppressed the deterioration of liquefaction. 8 refs., 5 figs.

    For the coal liquefaction, improvement of liquefaction conditions and increase of liquefied oil yield are expected by suppressing the recombination through rapid stabilization of pyrolytic radicals which are formed at the initial stage of liquefaction. Two-stage liquefaction combining prethermal treatment and liquefaction was performed under various conditions, to investigate the effects of reaction conditions on the yields and properties of products as well as to increase liquefied oil yield. Consequently, it was found that the catalyst contributes greatly to the hydrogen transfer to coal at the prethermal treatment. High yield of n-hexane soluble fraction with products having low condensation degree could be obtained by combining the prethermal treatment in the presence of hydrogen and catalyst with the concentration of slurry after the treatment. This was considered to be caused by the synergetic effect between the improvement of liquefaction by suppressing polymerization/condensation at the initial stage of reaction through the prethermal treatment and the effective hydrogen transfer accompanied with the improvement of contact efficiency of coal/catalyst by the concentration of slurry at the stage of liquefaction. 4 refs., 8 figs.

    To investigate the behavior of coal liquefaction reaction in early stage as a part of studies on the coal liquefaction characteristics using NEDOL process 1 t/d process supporting unit (PSU), coal slurry sample was taken from the outlet of slurry preheater located in the upflow of liquefaction reactors, and was tested. Tanito Harum coal was used for liquefaction. Preheater was operated under the condition of pressure of 170 kg/cm{sup 2}, gas flow rate of 64 Nm{sup 3}/hr, and at temperature up to 410{degree}C at the outlet, in response to the standard test condition. The slurry sample was discharged into a high temperature separator with temperature of 250{degree}C. Liquefaction was not proceeded at the outlet of preheater. Solid residue yielded around 80%, and liquid yielded around 15%. Gases, CO and CO2, and water yielded also small amount around 3%. The solid sample contained much IOM fraction (tetrahydrofuran-insoluble and ash), and the liquid contained much heavy oil fraction. Hydrogenation was not proceeded, and the hydrogen consumption was very low showing below one-tenth of that at the usual operation. Hydrogen sulfide gas was formed at early stage, which suggested that the change of iron sulfide catalyst occur at early stage of liquefaction. 1 ref., 5 figs., 2 tabs.

    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.

    In relation to coal liquefaction reaction, the effect of the coexistence of transferable hydrogen (TH) from process solvent on reduction of radical concentration and the effect of pre-heat treatment on average structure of coals were studied. In experiment, change in radical concentration with temperature rise was measured using the system composed of Yallourn coal and process solvent. The results are as follows. Process solvent with a wide boiling point range of 180-420{degree}C is effective in suppressing an increase in radical concentration even at higher temperature. The effect of hydrogen-donating solvent increases with TH. It was also suggested that high-boiling point constituents in solvent stabilize radicals even over 400{degree}C by vapor phase hydrogenation. The experimental results of pre-heat treatment are as follows. Although the conversion improvement effect of TH is equivalent to that of the model solvent, TH tends to produce soluble products with smaller ring numbers. It was thus suggested that pre-heat treatment in process solvent is effective to inhibit retrogressive reactions. 6 refs., 5 figs., 1 tab.

    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.

    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.

    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.

    Discussions were given on features of various kinds of coal liquefaction catalysts exhibited by them in hydrocracking of coal (Taiheiyo coal), and particularly on selectivity of the reaction in its initial stage. Four kinds of catalysts were tested: Adkins catalyst which is an oxide of copper and chromium, Fe2O3+S, Mo-TiO2 and MoS3-Al2O3. Three grams of coal and 0.3 gram each of the catalysts were charged into an autoclave reactor and experiment was conducted under an initial hydrogen pressure of 10 MPa, temperatures from 653 K to 693 K and for durations of 0 to 120 minutes to derive apparent reaction rate constants. The MoS3-Al2O3 catalyst has promoting the reaction apparently in the primary reaction at any temperature, while the other catalysts had the rate constants varied in the initial and the later stages. It was recognized that the temperature dependence of rate constants varies considerably according to the types of catalyst. Particularly the MoO3-TiO3 catalyst has small temperature dependence in the rate constants, and high molecular weight reducing power. 3 refs., 4 figs., 3 tabs.

    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.

    The liquefaction reaction system of an NEDOL process coal liquefaction 1t/d PSU was opened and checked to investigate the cause of the rise of differential pressure between liquefaction reactors of the PSU. The liquefaction test at a coal concentration of 50 wt% using Tanito Harum coal was conducted, and it was found that the differential pressure between reactors was on the increase. By the two-phase flow pressure loss method, deposition thickness of deposit in pipelines was estimated at 4.4mm at the time of end operation, which agreed with a measuring value obtained from a {gamma} ray. The rise of differential pressure was caused by deposit formation in pipelines connecting reactors. The main component of the deposit is calcite (CaCO3 60-70%) and is the same as the usual one. It is also the same type as the deposit on the reactor wall. Ca in coal ash is concerned with this. To withdraw solid matters deposited in the reactor, there are installed pipelines for the withdrawal at the reactor bottom. The solid matters are regularly purged by reverse gas for prevention of clogging. As the frequency of purge increases, the deposit at the reactor bottom decreases, but the deposit attaches strongly to pipelines connecting reactors. It is presumed that this deposit is what Ca to be discharged out of the system as a form of deposition solid matter naturally in the Ca balance precipitated as calcite in the pipeline connecting the reactor. 3 refs., 5 figs., 4 tabs.

    This paper reports the achievements in the Sunshine Project in fiscal 1988 in studies on the studies of the initial process in liquefaction. It is intended to identify the swelling phenomenon in coal particles in the coal slurry preparation and preheating processes, and change in the slurry viscosity associated with the heating. The slurry viscosity starts decreasing from around 300 degrees C at which the liquefying reaction begins, and decreases sharply at around 350 degrees C. Therefore, rise in the viscosity at temperatures below 300 degrees C is caused by factors other than the liquefying reaction. The rise starting at 100 to 120 degrees C is due to absorption of the solvent by coal. The rise starting at 210 to 260 degrees C requires further discussions. The equilibrium swelling ratio was measured on different types of coals by using the hydrogenated anthracene oil solvent. No coals swelled at 100 degrees C. The temperature of 200 degrees C largely divides coals into those swelling and those not swelling. At 300 degrees C, the coals were divided into those shrinking after largely swelling, those not swelling and those swelling monotonously. For consideration of the utilization as an auxiliary solvent, petroleum-based heavy oil was used to perform coal liquefaction to discuss effects of the solvent on the liquefaction rates. (NEDO)

    This program is aimed at development of iron-based catalyst suited for direct hydrogenation type coal liquefaction by elucidating the effects of the catalyst on the liquefaction reactions. The iron-based catalyst seems to act as the radical stabilizer rather than the reaction promoter, because the increased quantity of the catalyst and increased H{sub 2} pressure share the common pattern rather than the catalyst enhances the activity, which is associated with increased reaction temperature or residence time. This is more notably observed when the coal species is changed to brown coal. In other words, recombination of the decomposition products by polycondensation is accelerated in the presence of the catalyst in decomposition of brown coal from bituminous coal, with the result that the catalyst effects are more notably observed. Whether this results from difference in age between brown coal and bituminous coal or content of specific types of ashes should be elucidated, because this point is considered to deeply relate to eventual development of the liquefaction reaction system. The FY 1980 program includes the primary screening of different types of iron compounds and tests of some iron-metal-based catalysts. (NEDO)

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

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

    The reaction velocity constant of coal or the distribution of products in a high-pressure hydrocracking process of coal are found not to be affected by the temperature rise rate. The liquefaction of coal using CO and water is analyzed using a high-pressure differential thermal analyzer. The hydrogen gas generated during the water gas reaction reacts with CO for the formation of alcohols, carbonic acid, etc. The reaction rate is found to be higher when the specimen contains more oxygen. When coals greatly different from each other in terms of thermolytic reactivity, caking property, and intersolubility with medium oils are mixed, synergistic effects are exhibited, positive when active hydrogen supply is abundant and negative when it is short. In the case of the Hokkaido coal which contains 73.0-87.4% carbon, the grain diameter does not affect the liquefaction rate when the coal is crushed to the 48-mesh size approximately. Reaction velocity in direct liquefaction does not relate to hydrogen pressure. Asphaltenes in coal liquefaction are produced at the beginning of reaction, to be reduced in molecular weight due to cleavage of methylene crosslinks with the progress of reaction. Studies are conducted in a 0.1t/d-capable bench plant about liquefaction reaction characteristics and coal liquid properties, and chemical structures. (NEDO)

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

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

    This paper reports the research of coal liquefying technologies in the Sunshine Project in fiscal 1988. The research was performed with importance placed on the fundamentals of coal liquefaction and high value added compounds. Production of n-paraffin in the liquefying reaction occurs from reduction of acidic ester, and this ester structure contributes to cross-linking of aromatic rings. Most of the aromatic rings in coal has long side chains. A hypothesis was assumed that these chains have been produced from reaction of lignin in plants with fatty acid or alcohol. The hypothesis was verified from a synthesizing reaction by model substances. This could be said an initial reaction model for coalification. In order to verify de-alkylating reaction of the liquefied oil, model substances were used to investigate the products. Benzene having long alkyl side chains have the alkyl group dissociated, and on the other hand cyclization progressed producing naphthalene. Melting performance during coking is attributed to a great amount of solvent soluble low molecular constituents contained in coal. These constituents are contained in close contact in a net-like structure, which is loosened only by heating extraction, and extracted. They have no hydrogen donating performance. (NEDO)

    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.

    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.

    Membrane lipids in archaebacteria are different from those of eubacteria and eukaryote which are fatty acid esters of glycerol. Archaebacterial lipids are mainly ether-linked lipids composed of glycerol linked to two molecules of isoprenoid phytanyl groups or of ether-linked glycerol with phytanyl group. This structural feature is one of the origins of survival and growth of archaebacteria in extreme conditions of high temperature, strong acid or alkali. It is considered that geranylgeranyl phosphate (GGPP) is synthesized and attached to glycerol phosphate, followed by reduction of the double bond in the geranylgeranyl moieties to form the diether lipids while the head-to-heat condensation of the phytanyl groups produces the tetraether lipids. Aiming to elucidate the lipid biosynthesis mechanism in a hyperthermophilic archaebacterium, Sulfolobus acidocaldarius, the gene of GGPP synthase was cloned with the aid of carotenoid synthesis in phytopathogenic Erwinia uredovora and its sequence was studied. 29 refs., 9 figs.

    This paper describes the results of liquefaction tests of Mongolian coals using an autoclave and a flow micro reactor. Uvdughudag coal, Hootiinhonhor coal, and Shivee-Ovoo coal were used for liquefaction tests with an autoclave. Oil yields of Uvdughudag and Hootiinhonhor coals were 55.56 wt% and 55.29 wt%, respectively, which were similar to that of Wyoming coal. Similar results were obtained, as to produced gas and water yields. These coals were found to be suitable for coal liquefaction. Lower oil yield, 42.55 wt% was obtained for Shivee-Ovoo coal, which was not suitable for liquefaction. Liquefaction tests were conducted for Uvdughudag coal with a flow micro reactor. The oil yield was 55.7 wt%, which was also similar to that of Wyoming coal, 56.1 wt%. Hydrogen consumption of Uvdughudag coal was also similar to that of Wyoming coal. From these, Uvdughudag coal can be a prospective coal for liquefaction. From the distillation distribution of oil, distillate fraction yield below 350{degree}C of Uvdughudag coal was 50.7 wt%, which was much higher than that of Wyoming coal, 35.6 wt%. Uvdughudag coal is a coal with high light oil fraction yield. 2 figs., 5 tabs.

    The secondary hydroprocessing process in the two-stage hydrogenating liquefaction equipment under development at Nippon Brown Coal Liquefaction Company uses a fixed bed system. This paper describes operation of a bench reaction equipment using catalyst used in the pilot plant to compare it with fresh catalyst, and compare characteristics of the bench scale equipment with those of the pilot reactor. The catalyst is Ca-Ni-No/Al2O. The reaction was carried out in a gas-liquid downward parallel-flow fixed-bed reactor using deashed oil (DAO) with the same material as that used in the pilot plant and the same equilibrium solvent. The experiment result indicates that the used catalyst had its activity fallen below the fresh catalyst, but its temperature dependence was identical, and the selectivity on products of both catalysts was also identical. The result of reactions in the bench scale equipment clarified that the relationship between the DAO conversion rate and denitrogenation activity and the relationship between fa and H/C in the products are in good agreement, and that there is no difference in reaction selectivity. 5 refs., 6 figs., 1 tab.

    The Research Center for Carbonaceous Resources was established in April 1991 for the purpose of developing a comprehensive process for converting carbonaceous resources into clean fuels or into materials equipped with advanced functions. In this report, the track records etc. of the center are introduced. Under study in the conversion process research department is the organization of a comprehensive coal conversion process which will be a combination of solvent extraction, catalytic decomposition, and catalytic gasification, whose goal is to convert coal in a clean way at high efficiency. Under study in the conversion catalyst research department are the development of a coal denitrogenation method, development of a low-temperature gasification method by use of inexpensive catalysts, synthesis of C{sub 2} hydrocarbons in a methane/carbon dioxide reaction, etc. Other endeavors under way involve the designing and development of new organic materials such as new carbon materials and a study of the foundation on which such efforts stand, that is, the study of the control of reactions between solids. Furthermore, in the study of interfacial reaction control, the contact gasification of coal, brown coal ion exchange capacity and surface conditions, carbonization of cation exchanged brown coal, etc., are being developed.

    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.

    Described herein are results of literature survey on brown coal liquefaction reactions and elementary techniques. Liquefaction of brown coal in the presence of CO and steam, or CO, H{sub 2} and steam has been investigated. It is not clear by the literature survey whether it is superior to the normal process which uses hydrogen. Brown coal contains moisture at high contents, and the drying techniques are necessary to be developed for its liquefaction. The future coal liquefaction plant will be much larger than the past one, and there are a number of problems to be solved, such as those involved in the designs of large-sized high-pressure slurry pumps, heat exchangers and preheaters. It is also necessary to develop the materials of and production techniques for large reactors which are serviceable under severe conditions. The solid-liquid separation for liquefaction products involves a number of the elementary techniques characteristic of coal liquefaction processes, and needs many technological developments. The one-stage brown coal liquefaction process is compared with the two-stage process for the secondary hydrogenation of SCR, but no clear conclusions are reached. (NEDO)

    Studied in the research are four iron-based catalysts, which are natural pyrite, synthetic iron sulfide, synthetic iron hydroxide, and catalyst-attached carbon. Tanito Harum coal is treated in a 0.01t/d-capable continuous operation furnace (once-through) under conditions of 450 degrees C and 170kgf/cm{sup 2} with catalyst addition of 1.0, 3.0wt% (catalyst-attached carbon 0.6, 1.0wt%), and a liquid yield of 41.5-48.6wt%-daf coal is achieved. A higher yield results when more catalyst is added. The same yield as achieved by the addition of 3wt% natural pyrite is obtained by the addition of 1.9wt% synthetic iron sulfide, 1.5wt% of synthetic iron hydroxide, or 0.7wt% catalyst-attached coal. The catalyst cost for treating a ton of coal is 4-9 hundred yen, which is far more expensive than the cost set forth as the target. Catalysts whose production process embodiment is now under study are natural pyrite and synthetic iron sulfide, and studies for others are just preliminary. Provided that the practical application of the liquefaction technology realizes in about 2000, then the petroleum price is predicted to be 23 dollars per barrel. Coal liquefaction products will have to be produced at a cost which will enable competition with the said petroleum price. (NEDO)

    Tar sand bitumen is petroleum-based ultra-heavy oil, and has a great amount of reserve like coal. However, there are still a lot of problems for its highly effective utilization. This paper discusses whether the light components in bitumen show independent behavior during the thermal cracking of heavy components, or not. Solvent effect and reaction mechanism during the thermal cracking are also derived from the change of their chemical structures. Athabasca tar sand bitumen was separated into light and heavy fractions by vacuum distillation based on D-1660 of ASTM. Mixtures of the both fractions at various ratios were used as samples. Negative effect of the light fraction on cracking of the heavy fraction was observed with dealkylation and paraffin formation Polymerization of the dealkylated light fraction to the heavy fraction was suggested due to lack of hydrogen in the thermal cracking under nitrogen atmosphere, which resulted in the formation of polymer. 3 refs., 6 figs.

    Recently various studies have been conducted concerning the state changes of materials obtained through mechanical alloying (MA) or mechano-chemical (MC) processing. What is noticeable is the quasi-steady state of almost all the materials obtained through various processes including MA and MC, and that the super cooling, supersaturating and high residue distortion realized under unbalanced conditions have not been clarified. In other words, the tracing capability to the external binding conditions is low. In this report, the appearance of the high temperature phase and high pressure phase obtained through MA or MC processing, the forming of amorphous, the mesomerism of the amorphous materials, the interesting phenomena generated by combination between the mechanical disturbance and chemical reactions were discussed with concrete examples, and a steady dissipative organization theory was approached from the viewpoint of dissipative structure development which is equal to the forming process of the quasi-steady phase. 34 refs., 2 figs.

    This paper introduces the surface photo reaction processes using synchrotron radiation, and its application. A synchrotron radiation process using soft X-rays contained in electron synchrotron radiated light as an excited light source has a possibility of high-resolution processing because of its short wave length. The radiated light can excite efficiently the electronic state of a substance, and can induce a variety of photochemical reactions. In addition, it can excite inner shell electrons efficiently. In the aspect of its application, it has been found that, if radiated light is irradiated on surfaces of solids under fluorine-based reaction gas or Cl2, the surfaces can be etched. This technology is utilized practically. With regard to radiated light excited CVD process, it may be said that anything that can be deposited by the ordinary plasma CVD process can be deposited. Its application to epitaxial crystal growth may be said a nano processing application in thickness direction, such as forming an ultra-lattice structure, the application being subjected to expectation. In micromachine fabricating technologies, a possibility is searched on application of a photo reaction process of the radiated light. 5 refs., 6 figs.

    An electrolytic solution has been recognized as an ion transporting system since the oldest time in the history of electrochemistry, and the chemistry related thereto forms the most basic field of electrochemistry. In this article, the progress of chemistry concerning electrolytic solutions since M. Faraday is briefly stated, and in view of very scanty structural knowledge available on other solutions in comparison with the structure of water on which extensive studies have been made, the respective structures of such non-aqueous solutions as the mixed solvent of N,N-dimethylformamide (DMF)-acetonitrile (AN) and the mixed solvent of dimethylsulfoxide (DMSO)-2,2,2-triphloroethanol (TFE) are studied. In addition, concerning the solvation when ions exist in such a non-aqueous solvent mixed system, the selective solvation of Cu {sup 2+} ions in the DMF-AN and Cu {sup 2+} as well as Cl {sup {minus}} ions in the DMSO-TFE is respectively explained, and the solvent effect, etc. of Cu {sup 2+} ions and Cl {sup {minus}} ions on the complex forming reaction are discussed. 17 refs., 8 figs., 2 tabs.

    Selective composition of optically active compounds by use of biocatalysts is discussed. No search is made for any particular microbes or enzymes, but predetermined ones are used. For an increase in the selective yield of L-type carnitine by reducing 4-chloroacetoacetic acid ester using baker`s yeast, the ester length should be enlarged to that of octyl ester. Just as in this case, steric control by ground substance modification is often effective. Lipase helps on esterification which is contrary to hydrolysis in an organic solvent and, even in the optical division in this process, steric control by ground substance modification (for example by changing the structure of the acyl section) is effective. Immobilization of biocatalysts for use in reaction occasionally exerts some effect on stereoselectivity. Two types of enzymes may be participating in a reaction and inhibiting selectivity, and then a two-layer system of water and organic solvent may be effective in performing steric control over the situation. Another measure is to inhibit the activity of either of the two enzymes by use of a selective inhibitor utilizing enzyme reaction. The kind of solvent is also an influential factor. 11 refs., 7 figs.

    For artificial coalification, condensation reactions of aromatic ring and activated compounds produced by dehydrating reaction of glucose were studied experimentally. In heat treatment experiment in water, three reaction specimens such as glucose, glucose and phenol, and glucose and benzaldehyde were fed into an autoclave together with distilled water, and subjected to reaction at 180{degree}C under spontaneous pressure for 50 hours. In hydrogenation experiment, the specimens were fed into an autoclave together with tetradecane and sulfurization catalyst, and subjected to reaction at 350{degree}C under initial pressure of 9.8MPa for 2 hours for gas chromatography (GC) analysis of products. As the experimental result, the reaction between glucose and aromatic ring in heat treatment in water occurred between aromatic ring and active fragment with a mean carbon number of 4-5 produced by decomposition of glucose. The reactivity was higher in benzaldehyde addition than phenol addition. 3 refs., 4 figs., 1 tab.

    Effort are under way at the environmental research center of Kansai Electric Power Co., Inc., aiming at developing mass production methods for the above-said feeds. The micro-alga feed means planktonic algae among various kinds of phytoplankton, and is fed not only to bivalves but also to lobsters and sea urchins. Out of the micro-alga stock that is owned by the environmental research center, the Pavlova lutheri belonging to the Haptophyceae which is fed at many sites of seed production, is put to mass production utilizing CO2. The product is fed to cockle seeds, and they are found improved in survival rate and growth rate. To ensure stable and efficient mass production of micro-algae, a transparent spiral tube type cultivator is being tested. As a method for stably feeding bivalves from their intermediate growth stage through the stage of grownup parent shells, artificial detritus feeds are being developed, to be produced out of some strains of large sea algae possessed by the environmental research center.

    Investigation was conducted for the purpose of deciding energy-saving vision in the region of Ikeda City, Osaka Prefecture. Ikeda City is lower in the use of electric lights per household than Osaka Prefecture or the whole country, and is higher in the consumption of city gas. The carbon dioxide exhaust of the City is less compared with that of Osaka Prefecture or the whole country. As to new energy, there is a good possibility of the use of solar energy. As a result of energy conservation diagnosis, about 25% energy saving was found possible in the government office building jointly used by the City and the Prefecture, and 21% in Kitateshima Junior High School. From these investigative results, proposals were made for the basic policy of the energy saving vision; they were, for example, to enrich one's life style by promoting efficient use of energy, to build an urban structure having less energy load, to enhance all citizens' consciousness about energy, to change the way of living by the community unit, to take the lead in energy conservation as the city administration to set an example for the whole city, to foster the environmental industry by dealing with energy problems, and to have a long-term outlook and tackle the issue with stress placed on feasible projects.

    Discussions were given on early degradation in up to about ten minutes in amorphous silicon solar cells. The experiment has used a model cell of single junction layer for power use with a Glass/ITO/P-i-n:a-Si/Al structure. Test samples were annealed at 130 degC for 30 minutes to eliminate hysteresis of degradation during storage. Xenon was used as an irradiation light source, and the temperatures were varied from 0 to 100 degC and the measurement time was set to 0.1 to 500 minutes. The result of the experiment may be summarized as follows: with regard to time-based degradation pattern for conversion efficiency, the tilt of a pattern to express degradation rate varies with temperature conditions, and changes in 10 to 20 minutes of light irradiation as a boundary; in long-term degradation after 20 minutes, the higher the environmental temperature, the lower the degradation is suppressed, but the rate of initial degradation up to about 10 minutes is higher as the higher the temperature; and the degradation rate increases as the higher the temperature in the initial degradation of about 10 minutes, whereas, corresponding to this fact, it is estimated that a phenomenon is involved, in which carrier recombination defect may increase. 4 refs., 7 figs., 1 tab.

    A 1 T/D solvent-extraction type coal liquefaction test plant was constructed and operated to obtain the technical data for the design of, and establish the techniques for, an efficient coal liquefaction plant. The FY 1980 program includes surveys on the materials for coal liquefaction plants, covering those already developed and under development, to clarify the problematical points; drafting the test schedules; and conceptual designs of the material testing facilities. The major problems involved in the materials for coal liquefaction plants include erosion by fluidizing coal slurry, hydrogen embrittlement of the reactor materials, and corrosion by the liquefaction products (e.g., stress-corrosion cracking of austenitic steel, and corrosion by organic acids). The surveys on materials research trends suggest that USA seems to concentrate their research efforts on the reactor materials. The corrosion tests are mostly of in-plant tests, but the stress corrosion and slurry erosion tests are conducted on a laboratory scale. The conceptual designs are drawn for some testing units, e.g., the loop type material testing unit and basic testing unit for jet-spray type slurry erosion. (NEDO)

    Development has been carried out on a Chinese coal liquefaction technology jointly by Japan and China. The Japanese side fabricated and built a small continuous testing equipment. Shenbei coal produced in Liaoning Province, Tienju coal produced in Gansu Province and Shenmu coal produced in Shaanxi Province were used as test sample coals. These coals were crushed, washed with water, sorted, dried, pulverized below 100 mesh, and used as the test samples. For catalysts, a reagent Fe{sub 2}O{sub 3} and S as an auxiliary catalyst made in China were used. Anthracene oil freed from crystal was used as a starting solvent when making one-through operation and recycling operation. Hydrogen used had purity of 99.5% or higher. The current fiscal year has performed smoothly to the end either of the one-through operation or the solvent circulating operation on RUN-2200, 2300 (Chenbei coal) and 2,400, 2500 (Tienju coal). Operation of 2600, 2700 (Shenmu coal) experienced noise in the stirrer of the reactor, and leakage of the circulating gas from the recycled gas compressor. In addition, the differential pressure during operating the last run has increased to 50 k, when the temperature and pressure were reduced, and substances clogging the reactor inlet line were removed. Three kinds of the liquefied oils were brought back to Japan for detailed analyses. (NEDO)

    A report was made on the result for fiscal 1979 of the development of a coal solvent treatment and liquefaction plant. With the purpose of establishing a technology of making equipment for a coal liquefaction plant by a solvent treatment method, R and D were conducted on a solid liquid separation method and on the construction and operation of an experimental equipment having a scale of the maximum 1 t/day coal processing, providing technical data for the construction of an efficient coal liquefaction equipment. In studying the operation of a centrifugal separator, it was run using heating solvent, dummy slurry and coal extraction slurry, with no abnormality found in each equipment and with knowledge obtained of the separation state of the solid. The machine is capable of obtaining SRC of 0.2-0.3% low ash contents. Water operation was performed for the extraction processing device (agitation tank, heating furnace, compression pump, circulation pump, etc.) of the 1 t/day experimental plant and, as a result, a relation was confirmed between a water flow rate and pressure loss of the piping part. The detailed design, manufacture and installation were completed for a part (pulverizer, solvent tank, feeding pump, etc.) of the equipment for the coal pre-processing slurry making process and the extraction process, with a trial run implemented for adjustment and confirmation of the operation. The cold/hot continuous trial run by a solvent smoothly proceeded, proving the performance to be the same as the specifications. (NEDO)

    Among the EDS, H-Coal and SRC-2 lined up in the coal liquefaction project of the U.S., the SRC is aimed at producing 6,000 t/day as a module for a 30,000 t/day commercial plant. They expect Ash contents (iron, sulfur, etc.) in coal without basically using catalysts. The products are applicable to fuels for electricity and gas for the moment. In the element technology, there are some problems in manufacturing hydrogen by gasification of residuals as well as in slurry systems, reaction towers, etc.. In the 30,000 ton commercial plant, the coal-liquefied oil costs $19.89/bbl (price as of 1978) assuming coal costs $29.47; therefore, the feasibility is strong as a substitute for petroleum. Japan's share for the required funds will be 86.8 billion yen (if 250 yen per dollar). Since the kinds of coal are conceivably increased in number through the improvement of the process, the Pacific rim countries and these which lie on the Indian Ocean are assumed to be the major coal producing countries for Japan. The stability in storage of coal-liquefied oil is experimentally excellent, as is the compatibility with petroleum products for example. Great results can be expected in the technical know-how and the spread of element technology for Japan. (NEDO)

    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.

    Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)

    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.

    An experiment and the examination were carried out in order to elucidate the optimum conditions in the falling liquid film reaction method, in the conversion of solar energy using the decomposition reaction of 2-propanol. The device for the experiment was constituted of a reaction container, tubular pump, cooling pipe, sampling container for effluent from the upper and lower part of the reaction container, and gas burette. Examined in the experiment were various factors such as a fibrous activated carbon (catalyst support), ratio for carrying catalyst, catalytic composition and heating temperature. In the experiment, with the temperature inside the reaction container fully stabilized under prescribed conditions, measurement was done for the hydrogen generation by the gas burette for 10 minutes as well as for the sampling of effluent. The experiment revealed that the heat utilization ratio reached the maximum of about 27% when the heating temperature was 90{degree}C using a catalyst with the ratio of RU and Pt 1 to 1 and the ratio for carrying catalyst 10wt%, so that a great improvement was obtained in the heat utilization ratio at a low temperature. Also obtained was a large inversion ratio of about 15%. 4 refs., 6 figs., 5 tabs.

    As a part of the project for internationalization of coal liquefaction technology, this paper reported on the potential survey for location of Indonesian low grade coal liquefaction (study of applicability of the improved BCL process and survey of hydrogen production technology using coal gasification). The survey was conducted of a locational possibility of a coal liquefaction commercial plant to be located at mine site in South Sumatra for Banko coal raw material. The improved BCL process was applied in which the results of the study by NBCL Takasago Research Institute were reflected. Further, the hydrogen production was studied by gasification of Banko coal, and the comparison was made with the conventional natural gas reforming method. As a result of the study using information/knowledge obtained during the conceptual design of Australian brown coal, the construction cost of commercial scale liquefaction plant with the Banko coal processing amount of 30,000 tons/day became 549.8 billion yen in the case of using natural gas as raw material for hydrogen production. This construction cost is the lowest as compared with 601.7 billion yen in the demonstrative BCL process and with 577.1 billion yen in the advanced BCL process. This is a process making use of features of Banko coal. The process for hydrogen production by the steam reforming method using natural gas has an advantage of increasing the production amount of coal-derived liquid the most of the three other methods.

    Financial assessment is carried out by estimating the liquefaction product cost (selling price) at which the predetermined rate of return on investment is to be earned, which is calculated by the DCF (discount cash flow) method. The cash flow is determined from the net after taxes for each business year, and the balance after the subtraction of long- and short-term borrowings is converted to the present worth as of the operation commencement year at the predetermined discount rate, and a total is calculated for the period. When the difference between the total and the equity does not vanish, the coal liquid selling price is changed, and this process is repeated until the difference vanishes. If a 20% reduction in the plant construction cost is feasible, the coal liquefaction product will be competing with the crude oil in the market in around 2030. Although the financial analysis is a profitability analysis from the fund providers' viewpoint, the benefit as seen from the project siting country needs to be assessed by an economic analysis, and probabilities are that, in the presence of great profits, the project will materialize if the two are found to earn more than average after the profits are impartially divided. Japan's benefits and expenditures are compared and subjected to an economic analysis, and a result of 6-15% is obtained. This means that the project will realize in case EIRR (economic internal rate of return) is higher than the fund procuring cost of 11%. (NEDO)

As a result of the study using information/knowledge obtained during the conceptual design of Australian brown coal, the construction cost of commercial scale liquefaction plant with the Banko coal processing amount of 30,000 tons/day became 549.8 billion yen in the case of using natural gas as raw material for hydrogen production. This construction cost is the lowest as compared with 601.7 billion yen in the demonstrative BCL process and with 577.1 billion yen in the advanced BCL process. This is a process making use of features of Banko coal. The process for hydrogen production by the steam reforming method using natural gas has an advantage of increasing the production amount of coal-derived liquid the most of the three other methods.

    This program is aimed at establishing the techniques for solvent-extraction type coal liquefaction plant by constructing and operating a 1 T/D test plant to obtain the technical data for the efficient plant. The test plant is operated to confirm the effects of temperature and coal slurry concentration on liquefaction conversion by the solvent-extraction for a short time in the furnace for the extraction unit. The extraction type coal liquefaction tests can be conducted for a reaction time of around 1 hour by the test plant. The recycled solvent purification unit is installed, to regenerate the hydrogen donor solvent. For researches on the solvent-extraction type coal liquefaction process, the continuous extraction is conducted, to investigate the effects of extraction reaction rate at relatively low pressure. The optimum hydrogenation conditions are studied for the test plant. It is confirmed that a Mo-based catalyst is suitable for the hydrogenation. The batch type reaction system is operated to investigate the liquid yield of Wandoan coal, and recycled solvent balances and compositions. (NEDO)

    In 1994, a memorandum on the research cooperation was agreed between NEDO and BPPT (The Agency for the Assessment and Application Technology) in Indonesia, based on the request for the coal liquefaction technology cooperation from BPPT. It includes the following items: conference for professionals to be held, invitation and training of Indonesian engineers, activity for joint field survey and potential survey of location of coal liquefaction commercial plant. Further in 1997, the secondary memorandum was concluded for the potential survey for securing the hydrogen required for coal liquefaction by coal gasification. The survey was summarized as the potential survey for location of coal liquefaction. In the testing study for improving economical efficiency of liquefaction process, it was made clear that the higher the Fe content of Banko coal is, the higher the reaction of liquefaction is, and that Fe compounds in coal show catalysis. In the Soroako area in Sulawesi island, there are the nickel mine run by PT. Inco. Soroako limonite is promising as catalyst material for commercial-scale coal liquefaction. In the gasification method, the plant construction cost increases, but the production amount of coal-derived liquid can be increased. That is more profitable than the production of hydrogen from natural gas. (NEDO)

    The research objective is the development of environmentally benign coal liquefaction technology and the studies on internationalization of coal liquefaction technology. Implemented for the former are (1) research on improvement and rationalization of liquefaction process and (2) research on advancement of liquefaction base technology. In (1), studies were made on in-oil preprocessing technology and scale suppressing measures for the purpose of obtaining reform/high grade of coal, and on improvement of liquefied oil collecting ratio, sophistication of coal slurry and attainment of light oil/high grade from liquefied crude oil for the purpose of optimizing liquefaction reactive conditions and improving a solvent. In (2), in developing high activity/high dispersion type new catalysts, catalytic sufurization behavior and activity manifestation mechanism were explored, as were iron hydroxide based iron ore properties and liquefaction reactive characteristics. The initial reactive characteristics of liquefaction for example were investigated for the purpose of collecting basic data for expanding kinds of coal. In order to attain the latter objective of the research, a feasibility study of liquefaction location was conducted, as were the investigation including sampling of iron ore for catalytic material and the investigation of coal gasification technology. After the completion of the Australian brown coal liquefaction project, the development of the coal liquefaction technology commenced in fiscal 1994 produced a number of useful records and ended in 1997.

    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.

    Mechanical grinding (MG) with mechanically stimulated reaction was performed on metal/polymer mixed powders. The starting materials used in this study were the metals of Mg, Ti and Mg{sub 2}Ni powders, arid polymer of PTFE, PVC and PE powders. The MG process was investigated using XRD, IR, SEM and TEM. According to XRD results, magnesium fluoride (MgF{sub 2}, TiF{sub 2}) and chloride (MgCl{sub 2}) were detected from MG products of the Mg/PTFE, Ti/PTFE and Mg/PVC blending systems, respectively. Explosive reaction was found during MG of both Mg/PTFE and Ti/PTFE. It was also confirmed by XRD results that the production of MgF{sub 2} had already been formed just before the explosive reaction in Mg/PTFE system. It was found from IR analysis that C-C single bond in the polymers, not only both in PTFE and PVC but also in PE, changed to double bond C=C. Hydrogen produced due to decomposition of PE on blending Mg{sub 2}Ni/PE was absorbed into C-Mg{sub 2}Ni-H as amorphous solutes. These mechanically stimulated reaction was powerful method for decomposition of engineering plastics. (author)

    Regarding excitation and deexcitation due to collision of electrons and deexcitation due to collision of baryons in nonequilibrium plasma, explanation is made about the general characteristics of the elementary processes involving their formation and disappearance and about the prediction of their sectional areas and velocity constants. As for the process of the formation of excited atoms and molecules by collision of electrons, it may be divided into the direct excitation in the ground state, excitation and light emission toward the resonance state, reexcitation and transformation of excited particles, recombination of electrons and positive atomic ions, and dissociation and recombination of electrons and positive molecular ions. As for the process of the disappearance of excited particles, there exist various courses it may follow, and it is quite complicated because it is dependent on the types of particles involved and the conditions the process proceeds under. Although the skeleton has been built of the theory of derivation of the sectional area of excitation due to collision of electrons and atoms/molecules, yet it is accurate enough only when applied to simple atomic/molecular systems, is far from satisfying in general, and is to be augmented by data from future experiments. 22 refs., 3 figs., 1 tab.

    This paper describes mainly a reactive separation membrane reactor, introducing its principle, history, membrane materials, and permeation mechanism. When a product is removed out of a system, the equilibrium shifts to the product side according to the law of Le Chatelier-Braun. The reaction invert ratio in this case can be explained with an idea that it is based on the equilibrium theory and the velocity theory. Simulations are also performed using numerical analyses. Historically, studies had been made in the 1980{prime}s on reaction velocity theory, permeation mechanisms, and engineering approaches. Reactions as the object of the studies were focused mainly on dehydrogenation react ion. Thereafter, studies have begun on permeation of substances with new membrane other than hydrogen and on biological field. Membrane materials used then were heat-resistant and chemically stable inorganic materials. Recent reports include polymer membranes, hydrophilic and hydrophobic Membrane (in biological field), liquid membranes, and composite membranes. Separation membranes may be divided largely into porous membranes (with micro ports ranging from several {angstrom} to several hundred {angstrom} )and non-porous membranes, each having its specific permeation mechanism. 9 refs., 3 figs., 2 tabs.

    For the purpose of toughening the matrices of fiber-reinforced plastics (FRPs), the effect of thermosetting/thermoplastic polymer alloys based on cyanate ester alloys is investigated. In the experiment, materials are heated and then allowed to set, which are mixtures of 87.0-43.5wt% of cyanate ester resin, 0-43.5wt% of epoxy resin, and 13.0wt% of soluble polyimide. FRP properties are examined by measuring the after-shock compressive strength, flexural elasticity and flaxural strength, and by performing morphology observation. It is then found that a cyanate ester/soluble polyimide system forms a polymer alloy with phase separation, that its glass transition temperature does not drop, and that the rupture strength is increased approximately twice. A carbon fiber-reinforced plastic (CFRP) incorporating this system is twice higher in after-shock compression strength than a CFRP incorporating a cyanate ester. The system withstands high temperatures, retaining at 200degC approximately 90% of the elastic modulus it exhibits at room temperature. 15 refs., 16 figs.

    In relation to coal liquefaction, the effect of inorganic minerals on liquefaction reactivity and the effect of hydrofluoric acid (HF) treatment on organic molecular structure of coals were studied by demineralization of low-rank coals in HCl or HF solution. In experiment, Taiheiyo coal specimen was deashed in HCl solution at 25-70{degree}C for 6 hours while agitating, and in addition, deashed in HF solution. Hydrogenolysis of the deashed coal specimen was conducted using tetralin or methylnaphthalene as solvent under initial hydrogen pressure of 1.96MPa at reaction temperature of 693K for 60min. The experimental results are as follows. The ash content of Taiheiyo coal hardly offers catalysis in hydrogenolysis reaction. Carboxyl group increases in demineralization of coal because of breakage of bridged bonds. Organic structure of coal changes by demineralization in dense HF solution. Change in organic structure of coal by demineralization in dense HF solution is dependent on treatment temperature. 2 refs., 4 figs., 1 tab.

    In order to clarify a humification process in the early stage of coalification, the nitrogen functionality of prepared glucose-glycine condensate was studied experimentally. In experiment, the condensate was prepared by heating the mixture of glucose, glycine and water in a autoclave at 130{degree}C for 50 hours, and furthermore heating the produced solid material in water at 300{degree}C. After the condensate was hydrocracked, the fraction, condensate and hydrocracking residue were analyzed by elementary analyzer, {sup 13}C-NMR, XPS, FT-IR, capillary GC-FID/NPD and GC-MS. As a result, the glucose-glycine condensate could be arranged on the basis of three types of nitrogen such as pyridine, pyrrole and quaternary amine type. Pyridine type nitrogen increased, while quaternary amine type one decreased with an increase in heating treatment temperature. Rich pyrrole type nitrogen and poor pyridine type one were found in light nitrogen compounds in hydrocracked products. 2 refs., 4 figs., 2 tabs.

    It is important to cool a photovoltaic (PV) panel, because increased panel temperature is accompanied by decreased power generation efficiency. The authors have proposed a PV power generation system combined with an adsorption chiller driven by low-temperature heat, and simulated temperature changes during the desorption cycle, where the chiller utilizes endothermic reactions of an adsorbent during the desorption cycle. Described herein are results of the tests carried out to validate possibility of controlling panel temperature increase. The system consists of the PV panel with which a bed packed with an adsorbent is monolithically combined, condenser and evaporator. It generates power during the daytime by sunbeams, and provides low-temperature heat during the nighttime by the evaporator. In particular, ice can be produced when methanol and activated coal are used as the adsorbate and adsorbent. It has an advantage of effective utilization of energy as the heat source, which has been merely dissipated by the conventional system in the air. Such a system is expected to be useful for promoting effective utilization of solar energy and for peak power shaving in summer. The initial targets are achieved by the tests. 4 refs., 10 figs.

    Solvothermal reaction is reaction under high temperature and high pressure, which is expected to fabricate new functional materials. In this study, the materials are classified into two fields, i.e., inorganic materials, metals and their composites and organic materials and their composites. 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. The necessity of a national project for researches on the solvothermal reactions is proposed from the viewpoint of resource, environment and energy. 777 refs., 38 figs., 26 tabs.

    Liquefaction is applied to various biomass wastes and unused biomass to study characteristics of the liquefaction in each case. The paper described the system of the conversion and use of biomass into energy, conducted the positioning of the liquefaction, and outlined a history of the liquefaction chemistry and the study. To obtain basic data of characteristics of the liquefaction of various biomass raw materials, the liquefaction was conducted changing operational factors for the purpose of clarifying the product distribution of oil and by-products and oil properties. A comprehensive consideration was made of the liquefaction based on basic data and literature reports on the liquefaction of various biomass. From the above-mentioned studies, it was concluded that the energy can be recovered in a form of oil by applying the liquefaction to various biomass materials. A series of the study clarified effects of various operational factors on characteristics of the liquefaction as well as effects of classification of biomass materials and composition of the materials on characteristics of the liquefaction. 141 refs., 78 figs., 56 tabs.

    For the purpose of promoting the introduction of new energy and enhancing the awareness of it in Izumi City, Osaka Prefecture, an investigational study was conducted of the structure of energy consumption, existence amount of new energy, subjects in utilization of new energy, etc. The energy consumption amount of the city is increasing mostly in electric power in the residential sector, but is decreasing in the business sector and industrial sector. It is leveling off in the transportation sector, but only the consumption amount of gasoline is markedly increasing. In the potential amount of new energy utilization in the city, the rate of solar energy/clean energy vehicles was high. As a result of the study, the following were made clear: It is effective to introduce new energy mostly used for citizen such as the household use photovoltaic power system/solar heat use hot water supplier/hybrid private car. Of waste energy, wind energy, biomass energy and temperature difference energy, it is effective for city to take the initiative in introducing them. It is effective for city/proprietor to introduce the natural gas cogeneration. (NEDO)

    The feasibility study is conducted for introduction of the district energy-saving measures in City of Aizu Wakamatsu, for which the actual situations of energy consumption and promising energy-saving measures are surveyed. The city has a typical basinal weather, cold in winter and very hot and humid in summer, and tends to have a longer air-condition period in a year. It is considered that there are many wasteful energy consumption items to be studied for reduction. In the area of moving means, dependence on public transportation systems is considered to be relatively low, suggesting that there are much space of reducing transportation energy by the measures such as self-imposed control on use of private cars, promotion of utilizing public transportation systems and fuel-saving type driving throughout the city. The promising energy-saving measures studied to verify the effects include introduction of PVM analyzers for establishing better cost/effect relationship between power consumed by air-conditioners and pleasantness; introduction of garbage power generation, co-generation and high-efficiency illuminators; improvement of power-factor; and demand control for air conditioning, rationalization of power-receiving facilities, introduction of systems for saving flushing water and improvement of air conditioners' outdoor facilities.

    To realize clean diesel exhaust, it is very important to clarify the atomization phenomena of the fuel spray. In this study, the initial stage of the atomization process of a diesel injection fuel spray was analyzed with a high-speed image converter camera under the conditions of atmospheric gas pressure and room temperature. As a result, it was found that the initial spray formation was greatly affected lay the condition inside the nozzle sac. In the case in which fuel existed in the sac, pin-like structure spray formation was observed at the initial injection stage. This phenomenon was not observed in the case in which no fuel was present in the sac, and a widely spread fuel spray formation was observed at the initial injection stage. The relatively low-speed fuel spray injected in the initial low-sac-pressure condition was pushed away by the subsequent fuel spray injected in the high-sac-pressure condition. 7 refs., 12 figs., 1 tab.

    Among the items of the solvent extraction and liquefaction plant technologies in the Sunshine Project in fiscal 1981, this paper describes the achievements in developing a 1-t/d experimental plant and the solvent extraction and liquefaction process. Basic facilities were completed by giving expansion constructions on the extraction reaction column, gas-liquid separation column, and hydrogenation reaction column. The operation was performed with the primary object placed on verifying the effect of measures on problems that have been extracted, and checking the solvent balance. The conversion rate at an extraction reaction temperature of 450 degrees C was 83%, agreeing with the result of the fundamental study. The solvent has turned light as a result of 153-hour continuous operation, but circulating use was possible. Progress of the reaction has become easily controllable in the hydrogenation system. Fundamental discussions were given on engineering aspects, which require further accumulation of data. In the research of the solvent extraction and liquefaction process, fiscal 1981 has performed discussions on liquefaction catalysts, and on the effect of the hydrogen donating solvents. The discussions were for the fundamental research to establish adequate conditions for the 1-t/d experimental plant by operating a small continuous operation facility to its full extent, and by using a batch type reaction device. Screening was also carried out on catalysts. (NEDO)

    This paper explains the results of development of direct hydro-liquefaction plant under the Sunshine Project in fiscal 1981. As element studies for supplementing and supporting a 2.4 t/day PDU (process development unit), in the research using a 0.1 t/day bench scale continuous type equipment of fiscal 1981, a hydrogenation experiment was conducted for anthracene oil and also, an examination was made on the reaction conditions of Taiheiyo coal and Horonai coal, as well as on the catalyst and reaction ratio and on the product material distribution. A medium oil equalizing test was performed using Taiheiyo coal in order to obtain knowledge about equalized medium oil. Liquefaction characteristics in the preheating process and reaction process were elucidated by means of a semi-batch device. Comparative studies were made between domestic and overseas coals, in coal properties and liquefaction characteristics using a shaking type autoclave. The performance of iron-sulfur based catalysts was also examined. In the research on a solid-liquid separation method, the basic properties of coal liquefied crude oil were measured such as general properties, solid grading distribution and distillation characteristics, with the basic tests carried out for standing separation, filtrating separation and centrifuging separation, providing selected materials of the solid-liquid separation method suitable for the crude oil produced by the direct hydro-liquefaction method. In addition, studies were conducted on the use of residual oil generated by solid-liquid separation, providing knowledge of the viscosity and thermal cracking. (NEDO)

    This paper describes the achievements in the Sunshine Project in fiscal 1981 in development of a solvolysis liquefaction plant. The solvolysis process is characterized by performing the first stage reaction (liquefaction) in a short time by using hydrogenated heavy solvent produced spontaneously in the process. This short-time liquefaction reaction was carried out continuously by using a 1-t/d experimental plant, and a prospect was obtained on smooth operation and realization of the device. A test using a testing device allowing the temperature to rise within several minutes was performed on the effectiveness of a hydrogenated coal based heavy solvent (fractions of a hydrogenated heavy anthracene as a model) as a study on the first stage reaction. Partially hydrogenated materials of polycyclic condensed aromatics in the heavy solvent is largely involved in the initial reaction. In the solid-liquid separation, solids and heavy fractions are selected and removed from the first stage reaction products, and the light fraction is supplied into the second stage reaction (hydrogenation). The solvent deliming process was tested by using a batch type solid-liquid separator, whose effectiveness was verified. Studies were performed by using Australian sub-bituminous coal on operation of a continuous operation device consisted of systems for the first stage reaction (liquefaction), solid-liquid separation, second stage reaction (hydrogenation), and solvent circulation.

    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.

    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.

    Hydrogenolysis of different rank coals as Taiheiyo coal (75.7C%) and Pittston coal (85.4C%) were conducted in the presence of four kinds of catalysts (CuCrO4, Fe2O3+S, MoO3-TiO2 and MoS3-Al2O3) with an addition of tetralin as vehicle. The variation in viscosity in every reaction system was traced in the initial stage of the reaction by a torque meter attached to an autoclave. As a result, in every system, the torque decreased in the initial stage of temperature rise because of reduction of a solvent viscosity. The torque subsequently increased with temperature indicating two peaks before the following gradual decrease. In Taiheiyo coal, both peaks were low, and its coal conversion was more than 85%, while in Pittston coal, both peaks were sharp and high, and both subsequent torque reduction and coal conversion were smaller than those of Taiheiyo coal. 5 refs., 10 figs., 2 tabs.

    This research was intended to find the desirable direction of technological development, by discussing the effects of coal gasification/liquefaction technologies from every angle, for the purpose coping with the social demand for steadily and continuously obtaining clean energy. This year, the examination was conducted not only on the energy conversion technologies of coal gasification/liquefaction, but also on the impact generating from the entire supply system of coal energy from coal mine development to mining, transportation, storage and conversion to secondary energy. For this purpose, while the outline was grasped of coal resources in the world as well as each technology for the mining, transportation, storage, electric power generation by gasification, and high calorie gasification, a case study was made on the assumption that electric power generation and high calorie gasification were conducted by importing 1,000 tons of coal from overseas, extracting the impact on the basis of this case study. In addition, examination was made on the position of coal energy in the energy supply of the future, with an impact investigated on condition that about 300 million tons were imported equivalent to roughly 16% of energy supply in the year 2000 or about.

    Basic research is conducted on the Solvolysis liquefaction process for the purpose of producing from coal an ashless, low-sulfur, pollution-free liquid fuel. In the research on the Solvolysis liquefaction (1st stage liquefaction) of coal using a hydrogenation solvent, the Solvolysis liquefaction of coal is studied, for which a refined Solvolysis pitch containing coal substances and a hydride of solvent refined coal are used as Solvolysis liquefaction solvents for the 1st stage. In the research on the 1st stage liquefaction reaction conditions using a high-temperature closed process, two methods are employed. One is a method that uses a mini-pump type reactor in which a small hermetic container is submerged in a high-temperature solvent for rapid heating and the other is a method that uses a pipe type reactor in which coal slurry is caused to travel through a pipe heated to a high temperature. For the analysis of the 2nd stage liquefaction (hydrogenation) reaction conditions, the properties of the 2nd coal liquid, and the constitution of the 2nd coal liquid, and the for the research on the 1st stage liquefaction capacity, the hydrogenation of anthracene oil and solvent refined coal as recyclable solvent models is studied.

    This paper explains the results of research on direct liquefaction reaction of coal in fiscal 1981. The direct liquefaction is a reaction of three phases, gas-liquid-solid, under high temperature and high pressure. A tube type was employed in order to increase volume efficiency of the reactor, the continuous phase disperse number was decreased in order to bring it close to plug flow, and the paste Re number was increased to some extent in order to prevent sedimentation of coal particles. Hydrogen was supplied from the tube halfway for the purpose of supplementing the lowering of hydrogen partial pressure with the progress of reaction. A gas-liquid separator was installed so that increase in gas quantity was controlled in the rear stage of the reactor. As for catalysts, iron ore-sulfur system was examined which was promising as a disposable catalyst in place of the conventional iron system. Effect of catalytic addition was clearly recognizable in comparison with non-catalytic, with an exothermic peak observed comparable to the coal hydrogenation reaction of 350-420 degree C. Its catalytic effect was also presumable from the high pressure differential thermal analysis curve. The catalytic mechanism in the case where sulfur is added to hematite and limonite is similar to that of Fe{sub 2}O{sub 3} - sulfur catalyst, with the center of activity supposed to be Fe{sub 1-x}S. The catalytic effect is largely dependent on the particle size. (NEDO)

    The research aims to develop a new-type high-efficiency reactor for direct coal-liquefaction from a reaction engineering viewpoint and, at the same time, to settle problems expected to occur in industrializing this technique. The research items are Item 1 on the analysis of characteristics of a tubular continuous reactor and Item 2 on high-activity catalysts. Under Item 1, on the assumption that liquefaction reaction is dominantly a reaction in a continuous phase, a reactor is selected in consideration of homogeneous-phase reaction, and operating conditions are set according to the selected reactor and to the liquefaction reaction characteristics. A somewhat large Re number is assigned to the paste. Since the hydrogen partial pressure lowers with the progress of reaction, hydrogen is resupplied at the middle of the reaction tube. The volume of gas increases toward the final stage of reaction, decreasing the continuous phase holdup. Since it is undesirable to let the decrease stand, a vapor-liquid separator is provided for the control of the gas volume. In this fiscal year, investigation is conducted into details so as to determine if the reactor is equipped with intended characteristics. Under Item 2, the iron ore is deemed to be the most promising as disposal catalysts for liquefaction. In this fiscal year, studies are conducted to disclose the activity etc. of catalysts of this type. (NEDO)

    This paper describes the research achievements in the Sunshine Project in fiscal 1992 in studies on a direct gasification catalyst. The paper summarizes the points where the catalyst research has reached to date. The catalyst surface effective for hydrogenation is the metal surface that can dissociate hydrogen. However, metals having large adsorption heat against hydrogen do not show the activity greatly because these metals are difficult of desorbing hydrogen having high dissociating activity. The coal liquefaction system has the surface oxidized by water content, wherein hydrogen dissociation cannot be expected, and sulfides are suitable. When a sulfide catalyst contacts hydrogen, the catalyst itself is desulfurized, producing H{sub 2}S and becomes a low-order sulfide. When atmospheric H{sub 2}S contacts this sulfide, it dissociates into HS and H, and this H behaves as active hydrogen. However, the liquefaction activity can be recognized even in a sulfuric acid type catalyst containing no sulfide whatsoever, wherein the H{sub 2}S partial pressure in the reaction system becomes extremely low. This fact means that the active hydrogen is not necessarily generated by the dissociation of H{sub 2}S. There is no other way but to think that hydrogen is dissociated directly without going through H{sub 2}S. If this is true, it provides a new guideline in developing and designing the future catalysts. (NEDO)

    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.

    This paper reports the summary of the research and development works in fiscal 1988. The following researches were carried out: as development of a bituminous coal liquefaction technology, studies by using a pilot plant, studies on support of the pilot plant (studies by using an experimental plant (studies by using a 1-t/d PSU, development of an optimal pretreatment technology for coals to be used for liquefaction, studies on improvement in fraction oil distribution in the NEDOL process, and studies by using a 1-t/d plant)), and (studies by using a small device (studies on coal liquefying conditions, and studies on solvent hydrogenation catalysts)). Studies were carried out on operation of the pilot plant, and on support of the pilot plant operation. Materials for auxiliary machinery were developed (including in-plant test of new materials), and so were the devices (including development of a let-down valve) as trial fabrication and development of the plant devices and materials. As coal type selection and survey, coal types were surveyed, and liquefaction performance of Chinese coals was tested. In order to develop applications of coal liquefied products and a refining technology, developments were carried out on up-grading of the coal liquefied oil, a petroleum mixing technology, and a technology to separate hetero compounds in coal liquefied oil, and applications of the compounds.

    Properties of the active gasification catalysts prepared by ion exchange reaction of CaCO3 and coal were studied. Several kinds of Ca-loaded coal specimens were prepared to compare their properties among them by physically mixing coal particles with CaCO3 ones in air, by kneading both materials in pure water while crashing and by impregnating CaCO3 into coal while agitating them in pure water. Although Ca-loading onto the impregnated specimen was nearly one-half that of the kneaded one, its catalysis was equal to the kneaded one. CaCO3 greatly accelerated steam gasification only by mixing it with low rank coal in water, and such a high catalytic activity was caused by ion-exchanged Ca produced by the reaction between CaCO3 and COOH radical in coal. Aragonite of seashells yielded more Ca-loading than calcite of limestone, suggesting one of the useful treatment of seashell waste. 3 refs., 4 figs., 2 tabs.

    Although various chemical reactions are made use of at scenes of chemical industry for the acquisition of desired chemicals, the control of reaction process governing factors, such as temperature, pressure, catalysts, solutions, etc., is found to be carried out only on the empirical basis. At the present time, rational or optimum reaction designs are not to be prepared in a short period of time in the presence of the widespread shortage of knowledge about chemical reactions and of the shortage of understanding of chemical reactions at the micro level. Leading survey and research are conducted for the development of a 'chemical reaction simulator' technology to enable the acquisition of optimum reaction designing guidelines in a short period of time. Using the simulator, a chemical of his choice is inputted by a researcher engaged in the study of an real chemical reaction and then various techniques of computer science are mobilized for the preparation of a huge number of feasible reaction routes, and high-precision simulations are conducted for the feasible reaction routes. The results achieved this fiscal year are reported. The purpose of this research and its ripple effect on new product industry creation are stated. Then the positioning, mission, and concept of such a chemical reaction simulator are described. Finally, the result of research and survey of knowledge databases and the result of research and survey of computational chemistry are stated. (NEDO)

    Activities were performed with an objective to establish fundamental technologies related to photoreactive materials capable of ultra-high density and high resolution indication by controlling structures and assemblies of molecules by using light. The activities were taken in the four fields of elucidation of photoreactive mechanisms and fundamental properties, development of the materials, material processing and constituting technologies, and evaluation technologies. Specifically speaking, the activities were developed on the multiplexing technology applicable to ultra-high density recording, sensitivity responsiveness, and material stability in photochromic materials and photochemical hole burning (PHB) materials. For the photochromic materials, development was performed on photochromic materials to form associations, and on a thin film forming technology by means of the organic molecular beam epitaxial process. For the PHB materials, research was implemented on use of the materials at elevated temperatures, development was made on quinone-based materials, research on enhancement of multiplexity, development on porphyrine-based materials, and research on the organizing technology. In the research of the use at elevated temperatures, development was progressed on a material that can retain under the liquefied nitrogen temperature the status of wavelength multiplexed recording that has been formed under the liquefied helium temperature.

    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.

    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.

    In this paper, bond cleavage reactions are discussed in relation to the softening and solubilization of coal. Were used 9,10-dihydroanthracene (DHA) and 9,10-dihydrophenanthrene (DHP) as models of hydrogen donating compounds in coal, and bibenzyl, 1,2-diethane, benzylphenylether, and 1,5-dibenzylnaphthalene were used as models of bridge structure compounds. They were compared mutually, as to reactivity of coal against DHA and DHP. For the homolytic cleavage of bridges, DHA with excellent radical supplement performance provided excellent hydrogen donating performance. While, for the ipso-position cleavage of bridges, it was found that DHP can act as an effective hydrogen donor. For the reaction between coal and hydrogenated aromatic compounds, cleavage of relatively weak bonds, such as ether linkage and dimethylene linkage, occurred at about 380{degree}C, and hydrogen from DHA or DHP was consumed. On the other hand, the results suggested that the cleavage reaction at ipso-position affected by hydrogen donating solvent is also important at temperature range around 420{degree}C. 2 refs., 3 figs., 1 tab.

    Recently, taste and bioactivation of large number of oligopeptide become clear, and the development of the efficient synthetic method becomes the urgency. In the production process by conventional enzyme reaction which combined the crystallization, because the solubility of the product to the water which is reaction solvent is low, the yield remained at about 60%, and the problem of reaction inhibition of the product by the crystal had also been indicated. In the enzyme synthesis of the aspartame in which he is the representative oligopeptide, it aimed at the establishment of the new synthesis method which can improve yield and reaction rate, while the segregation enzyme was continuously utilized. In this synthetic method, supply of organic solvent which dissolved the substrate, extraction of the substrate from organic solvent to water phase, synthesis reaction by the segregation enzyme in water phase, extraction of the aspartame which is a product from water phase to organic solvent progress, and they continuously progress by one complete mixing reactor. The process which controlled these speeds and yields was quantitatively analyzed, and material balance style considering substrate, enzyme and mass transfer of the product and enzyme reaction speed was deduced. The optimum operating condition for improving yield and productivity of the purpose product using this solution was examined, and optimum supply concentration and agitation speed of aspartic acid which was a substrate were started, and the optimum operating condition which realizes the improvement in high yield and productivity over 90% of the aspartame was clarified. Like this, it is that this research adopts features of liquid Citrus nobilis two-phase partition for the enzyme synthesis of the aspartame, and it is considered that there is a value, because it is the creative research which verified that the productivity can be greatly improved by the utilization of the chemical-engineering technique, and because the industrial contribution is also big.

    It is clarified that the photo-excitation hydrophilic reaction increasing wettability remarkably is induced by changing surface structure of titanium oxide radiated light. There are already many examples being in practical use of coating products applied hydrophilic reaction of titanium oxide surface such as drip-proof side millers for automobiles, self-cleaning building materials, and the like. When surface of titanium oxide having high activities for oxidisation and decomposition is coated organic materials and radiated light, wettability of surface changes as organic materials are decomposed. If it is possible to change wettability shaping pattern drastically by radiating light, the possibility of application for printing materials will be developed. After increasing contact angle by coating water and oil repellent on the titanium oxide thin film, images can be shaped by radiating light into pattern for changing surface of titanium oxide to be ultra hydrophilicity as decomposition of repellent. At that time, contact angle is 150 degree in water, 80 degree in oil, for not radiated aria, and is 0 degree in water and oil for radiated aria. Application for control technology of wettability keeps possibility of broader development to itself, not staying ability of self-cleaning and drip-proof. (NEDO)

    In order to structure a chemical reaction process that does not discharge a large amount of waste by-products or harmful chemical substances, or so-called environment friendly process, investigations and discussions were given based on the results derived in the previous fiscal year. A proposal was made to reduce environmental load on development of oxidized and dehydrogenated catalysts that can produce selectively ethylene, propylene and isobutylene in an oxidation process. In liquid phase oxidation, redox-based oxidation and solid catalyzation of automatic oxidation reaction were enumerated. In acid base catalyst reaction, development of ultra strong solid acid was described to structure no pollution discharging process. In the fine chemical and pharmaceutical fields, the optical active substance method and the position-selective aromatics displacement reaction were evaluated to reduce environmental load. A questionnaire survey performed on major chemical corporations inside and outside the country revealed the following processes as the ones that can cause hidden environmental problems: processes discharging large amount of wastes, processes treating dangerous materials, and processes consuming large amount of energy. Development of catalysts is important that can realize high yield, high selectivity and reactions under mild conditions as a future environment harmonizing chemical process. 117 refs., 23 figs., 22 tabs.

    The baking process in cement production means the process that the raw materials which were mixed and pulverized in the raw material preparation process are charged into a reaction furnace which is called kiln, and clinders (intermediate product of cement) are generated. It is the process which affects quality as well as production cost of cement more significantly than anything else. In this article, an outline of the above baking facilities, how the raw materials change and clinkers are generated therein, and how they are controlled are introduced. Clinkers are composed of such products as alite, belite, aluminate and ferrite, etc. which were generated after decomposition reactions of such raw materials as lime stone, clay, silica rock and iron oxide in the above kiln. The essential ponts of the process control which makes the generation reactions of clinker compounds efficiently are such two points as well balanced raw materials to be charged into the baking facilities and stable operation of such facilities. The quality of cement which is required as finished goods is achieved by the quality control at each intermediate process and the quality tests of cement. 5 refs., 10 figs., 2 tabs.

    Ring-opening of heteroaromatics and heteroatom-removal reaction were studied experimentally using the acidic catalyst containing phosphoric acid for improvement of an upgrading method of coal derived oils. In experiment, some Ru-carrying metal oxide catalysts such as RMZ, RML and RMN catalyst, and MNP catalyst containing phosphoric acid were used as specimens. Nuclear hydrogenation reaction and hydro-denitrogenation reaction of dibenzothiophene and carbazole were compared with each other. The experimental results are as follows. Both RMN and RMNP catalysts offer a superior selectivity in nuclear hydrogenation reaction and hydro-denitrogenation reaction of carbazole. Although both catalysts offer an extremely high nuclear hydrogenation activity at 360{degree}C, these offer the high selectivity of denitrogenation products at 430{degree}C. In comparison of the activities of MN and MNP catalysts with the same Mn2O3:NiO ratio, MNP catalyst offers the higher denitrogenation activity than MN catalyst at 430{degree}C. 1 ref., 3 tabs.

    This project is aimed at establishment of the basic technologies for photo-reactive materials capable of, e.g., superhigh-density, superhigh-resolution display using photo-functions to control structures and associated conditions of the molecules. More concretely, the efforts are directed to realization of the technologies for multiplexing, sensitivity-response and material stability, applicable to superhigh-density recording by photochromic and photo-chemical burning (PHB) materials. For the photochromic materials, the long-chain alkyl derivatives of photochromic compounds, e.g., spiropyran and fulgide, are formed into thin films by the LB method, in order to develop organic, superhigh-density recording devices by controlling their associated conditions, and controlling of the photochromism reactions in the films is studied. Those studied for the PHB materials include improvement of heat resistance of the materials, development of quinone-based materials and improvement of their degree of multiplexing, and development of porphyrin-based materials and of technologies for structuring them. The comprehensive survey/research activities include extraction of the problems involved in the themes mainly related to the committee activities, and related technologies. (NEDO)

    With an objective of developing a room heating system utilizing a solar chemical heat pump, an experimental system was fabricated to evaluate its performance. Steam was employed as a working gas, and for a reaction material, calcium-chloride was used, which has a reaction temperature zone permitting safe use and fitting the purpose among other hydrate systems and has high standard enthalpy in hydration. Water was used as a solar heat transferring medium. The system operates under the following principle: a container I is filled with hydrated salt and a container II with water, the two containers being linked with a pipe interposed with a valve; heat is inputted and outputted by performing charging and discharging alternately; and the role of a heat pump is played by deriving from environment the heat of water evaporation in the container II during discharging. The COP must take into account the electric power consumption of the water circulation pump to transfer solar heat. A COP of 0.256 was derived as a result of the experiment. 3 refs., 5 figs.

The target is to establish the technology of the multiplex recording which is applicable to the super-high density recording in relation to PHB materials/organic photochromic materials which have potentiality of photon-mode recording. PHB materials were developed which have potentiality of 600 wavelength multiple recording and 5 electric field multiple recording in 4.2K and 9 wavelength multiple recording in 77K. Photochromic materials were developed which have high sensitivity and preservation stability and have potentiality of 10 wavelength multiple recording at room temperature. A new photo-recording method was found out by which the orientation of liquid crystal is photo-controlled and potentiality of the multiple polarization was shown. Moreover, the fabrication was successfully made of PHB materials and photochromic materials which make non-destructive readout operation of more than 10{sup 4} times possible. (NEDO)

    This paper describes the results of the experiment in which crystallization of protein of reactive center purified from the photosynthetic film of thermophilic purple sulfur photosynthetic bacterium Chromatium tepidum whose hyrogen donor in photosynthesis is H2S instead of H2O was attempted. Crystallization was carried out by the vapor diffusion method and particularly by using ethylene glycol as precipitator at 4[degree]C after various investigations on the conditions of crystallization. By X-ray diffraction, this crystal was found to belong to the rhombic system, and it was estimated that the lattice constants, a, b, c equal to 140[angstrom], 190[angstrom] and 80[angstrom] respectively. This bacterium is a thermophilic bacterium having the optimum growth temperature of 48-50 [degree]C and utilizes CO2 or H2CO3 as corbon source, ammonium, urea etc. as nitrogen source and thiosulfate as sulfur source. Moreover, another purpose of this investigation was to determine the thermophilic location by elucidating its configuration (although, as a result, the analysis of configuration had no sufficient resolution). It was confirmed that the enzyme system of photosynthetic film and its cytoplasm obtained by ultrasonic spallation of this cell have CO2 fixing activity utilizing light energy. 23 refs., 14 figs., 3 tabs.

    The purpose of this study was to investigate a traffic environment that can reduce traffic accidents of elder walker. We focused on the relationship between traffic accidents and elder person`s spatial attention. In this paper, an adolescent subject`s and an elder subject`s pointing movement to a visual target was measured in three conditions. Condition 1: Only target was presented. Condition 2: Auditory stimulation was added at a location the same distance from the center as that of the targets but in the opposite direction. Condition 3: Auditory stimulation was added at the same location as the target. The targets were placed in extra working space with the distance of 1.5 meter from a subject to the targets. In adolescent subjects, results showed that in Condition 3, latency was shorter and the error rate of pointing movements was lower than in the other conditions. In elder subjects, results showed that in all Conditions, ignore ratio to peripheral targets is higher than adolescent subjects. Nevertheless, in condition 3, ignore ratio was lower than in the other conditions. These results suggest that, it is possible to draw elder walker`s spatial attention and to control spatial attention by auditory stimulation. 13 refs., 6 figs., 1 tab.

    Experiment was made on stereo-selective hydrolytic reaction of trifluoroethyl ester of ketoprophene by various kinds of lipase. In addition, study was made on the stability of lipase simply immobilized on porous ceramics under the existence of organic solvent. In the experiment, the hydrolytic activity of 8 kinds of lipase was studied for ketoprophene monochloroethyl ester (1a) and trifluoroethyl ester (1b). The experiment result showed that lipase M originating in mold (Mucor Javanicus) shows a high reactivity and stereo-selectivity for the compound (1a). The lipase immobilized on porous ceramics was easily obtained by a very simple method composed of only throwing carriers into enzyme suspension, agitation and refrigerated drying. The lipase immobilized on porous ceramics 'Toyonite 200-A' synthesized from kaolinite retained the residual activity of nearly 50%, original selectivity and considerable stability after 5 times of repetitive uses. This study result is useful for bio- reactors and bio-sensors for synthesis or decomposition of compounds. (NEDO)

In the experiment, a pellet-like activated carbon-supported ruthenium catalyst was used for the acetone hydrogenation with hydrogen and acetone supplied to the catalyst layer at a space velocity of 400-1,200 or so. In the external pipe of the double-pipe type reactor, a heating medium oil was circulated in parallel with the flow of the reactant, with the heat of reaction recovered that was generated from the acetone hydrogenation. In this experiment, an 1wt%Ru/C catalyst and a 5wt%Ru/C catalyst were used so as to examine the effects of variation in the space velocity. As a result, from the viewpoint of recovering the heat of reaction, it was found desirable to increase the reaction speed by raising catalytic density and also to supply the reactant downstream inside the reaction pipe by increasing the space velocity. 1 ref., 6 figs., 1 tab.

    Processes that contain latent environmental problems are the massive generation of wastes (inorganic salt, acid catalyst, base catalyst, and huge quantities of wastewater), handling of dangerous substances (use of hydrogen fluoride, use of phosgene, and use of substances whose discharge is legally controlled), processes which consume much energy (circulation of quantities of raw materials, use of quantities of solvents, separation of products with difficulties, use of high pressure, and multiple stage reaction), and processes which are expected to use resources now remaining unexploited. As an element technology for the solution of problems, there is the development of a solid redox catalyst for liquid phase oxidation. As compared with a liquid phase homogeneous catalyst, it discharges less inorganic wastes, facilitates the separation, recovery, and treatment of inorganic salts, corrodes structural materials less, and is thermally stable. An alkane partial oxidation catalyst when developed will achieve more energy conservation than an alkene oxidation catalyst. In relation to acid/base reaction, the zeolite catalyst will be improved and ultrastrong acids and ultrastrong bases will be developed, and these will reduce wastes, mitigate corrosion, and facilitate product separation. The development of a process is also expected which will avoid the use of toxic phosgene. (NEDO)

    The operation of a 1t/d PSU (process support unit) was studied for the NEDOL coal liquefaction process. In the modification of facilities, equipment and devices were procured for the product oil reforming facilities and their installation was partly accomplished. In the coal injection operation, a 60-day slurry operation was conducted, using coal types of the upper limit and lower limit qualities, for expanding the scope of coal types applicable to the NEDOL process and for exploring optimum conditions, and another operation of 37 days was conducted using Chinese coal and Chinese-prepared liquefaction catalysts, and the two operations were studied for difference in yields and in operationality. Characteristics of the liquefaction reactors were investigated and basic studies were made relative to the physical property of the yielded coal oil. In the operation for maintenance, the 1st liquefaction reactor was singly operated for an 8-day slurry operation, which was to check the progress of liquefaction in a 1-reactor setup. Concerning the reforming of the product oil, the hydrogenation reactors were checked for their response to temperature control. Moreover, hydrogenation solvents were produced for the PSU and for China. (NEDO)

    With an objective to improve the environment by substituting petroleum energy by coal, and by reducing emission of SOx and NOx, research and development has been performed on coal liquefaction technologies. This paper summarizes the achievements thereof in fiscal 1999. In the disassembling study, wear, corrosion, and wall thickness change were investigated, and non-destructive inspection was performed on the major four facilities, and such newly developed devices as the liquefying catalyst manufacturing facilities, the slurry heat exchanger, and the let-down valves. The sampled test pieces were investigated of changes in the mechanical properties by means of the metallic structure inspection, hardness test, tensile test, and impact test. Deposits in the devices were investigated of their depositing conditions and constituents. The result reveals that the 3 Cr-1Mo-1/4V-Ti-B steel developed for the high-temperature, high-pressure, and hydrogen environment of the coal liquefaction plant showed excellent low-temperature tenacity and maintained good characteristics. No problems were discovered in corrosion resistance if PP using materials are used. The slurry handling centrifugal pump and instrumentation vales were worn out severely requiring replacements during the operation, for which further discussions are desired to be given. (NEDO)

    This paper explains the results of development of a hydrohoist system in a direct hydro-liquefaction plant under the Sunshine Project in fiscal 1981. Coal liquefaction deals with three phases of gas, liquid and solid at high pressures of 100-300 kg/cm{sup 2}. Slurry consisting of coal, catalyst and solvent is once fed into a supply chamber by a low pressure slurry pump. A high pressure slurry formed in a liquefaction reactor, after the separation of gaseous object, is boosted by a booster pump and force-fitted into the supply chamber from the above, discharging the slurry in the chamber to the high pressure reactor side. Since the high pressure product is used as the driving liquid, a force-feeding motive force can be greatly curtailed. It is a motive force recovery type hydrohoist. The product slurry in the supply chamber is discharged from a valve in the upper part; with the inner pressure going down quickly, the discharge valve wears very little. The basic experimental equipment was manufactured in fiscal 1980, with a test research conducted using the improved main equipment in fiscal 1981, and with the conceptual design of the hydrohoist also implemented on the assumption that it was applied to a pilot plant.

    Among researches on solvent extraction and liquefaction technologies in the Sunshine Project in fiscal 1981, this paper describes the achievements in development of a solid-liquid separation technology. In the research of operation of a centrifugal separation device, a solid-liquid separation test was performed on slurry extracted from the Australian Wandoan coal being sub-bituminous coal. The deliming rate has reached 99% equilibrium at an addition rate of 20% by weight of anti-solvent (a kind of normal paraffin, which reduces solubility of part of coal extracts and enhances removal rates of ash and solids by utilizing coagulating action of the extracts). Asphaltene among the liquefaction formed materials may be recovered nearly completely, but the recovery rate for pre-asphaltene was lower. An operation test was also carried out by using slurry extracted in a 1 t/d experimental plant. In the study on operation of a 5-l/h continuous sedimentation and separation device, a maximum effect was derived with addition of anti-solvent at 25% by weight and at a stirring rate of 700 rpm. The solid-liquid separability changes depending on the kind of slurry. The low conversion rate slurry becomes difficult of separation because its viscosity is high and the difference in density between solids and liquid is small. Furthermore, the high conversion rate slurry has become difficult of separation due to small particle size of the solids. (NEDO)

    The above-named plant is constructed, and studies are conducted on its operation. Before the construction of this 2.4T/day-capable research plant, its details were designed in fiscal 1979 when the plan placed the plant at the Chiba establishment of the Mitsui Engineering and Shipbuilding Co., Ltd. The plan was altered in July of fiscal 1980 for the plant to be built at the Keihin steelworks site of the NKK Corporation, and then partial modification was implemented for the basic and detailed designs of the plant for the second year running. Furthermore, a review was made so that the results of the element studies that followed the designing of the details would be embodied, and the changes were reflected on orders placed for equipment and construction work. These processes culminated in the 2.4T/day-capable research plant, now complete and subjected to inspections by the relevant Government offices. In a study of the operation of the plant, an operating procedure is worked out, and water-handling tests are conducted for each of the stages of operation. The plant will be subjected to a full test operation, improved as required, studied for proper operation, and will undergo additional construction work as required, all these in preparation for a continuous operation in the future.

    This paper reports the operation of a pilot plant of a bituminous coal liquefaction technology as the 1/2 report. The operation research of the Run-2 through the Run-4-2 was conducted using, as the material, tanitoharum coal which is operating basis coal. The Run-2 achieved a coal charging continuous operation for 42 days. During the operation of 80% slurry supply load, various data were obtained including material balance under the NEDOL standard liquefaction conditions, with a liquefaction yield of 54% daf coal achieved. Steam blowing into the heating tube was found effective as measures to cope with coking generation in the heating furnace of a vacuum distillation tower. The softening point of liquefaction residuals was improved to 178 degrees C through the extracting adjustment of reduced pressure heavy gravity light oil fraction for washing. The Run-3/4-1 achieved a plant load ratio of 100% and a long-term coal charging continuous operation for 80 days, while the Run-3 achieved a slurry supply load of 100% under the NEDOL standard liquefaction conditions. The Run-4-1 achieved a high liquefaction yield of 58wt% daf coal. Performance was confirmed of a neutron beam source irradiation apparatus/measuring system and a tracer injection equipment. (NEDO)

    This research aims to prepare conceptual designs for a 250t/d-class and 500t/d-class coal liquefaction pilot plants based on the achievement of research on solvent extraction liquefaction of coal. It also aims to define the solvent extraction process and provide decision-making material relative to the development and promotion of coal liquefaction technologies in the future. Development started in 1978 of the technology of solvent extraction liquefaction of coal, and a 1t/d PDU (process development unit) was completed in 1981. Studies through its operation have continued for more than 3000 hours already, and technical data are being accumulated steadily. Techniques acquired through operating the 1t/d PDU have been put together, and rough process conditions are established. A rough process result is achieved of the same conditions. In these two respects, the newly developed process is equal to other processes. The phenomena in this process are roughly grasped. It is deemed that, with the existing technique combined with the technique acquired here, a technological level has been reached where conceptual designs of large pilot plants may be worked out for solvent extraction liquefaction of coal. Under the circumstances, with a view to developing a commercial plant whose main products will be fuel oils, conceptual designs are prepared for large pilot plants, and are compiled into this report.

    This program is aimed at establishment of the techniques for milling of brown coal treated by primary dehydration and slurry adjustment, and secondary hydration plant, as part of the project for developing the techniques for liquefaction of brown coal. Brown coal (Australian Yallourn coal) treated by primary dehydration, solvents (creosote and decrystallized anthracene), and catalysts are used as the stock samples, to investigate the coal characteristics with respect to milling crushability, dehydration and liquefaction reactivity, and the slurries are prepared by changing coal charge rate, solvent and preparation temperature, to collect the data regarding, e.g., coal concentration, coal particle size, moisture level and liquefaction reactivity. It is found that milling crushability tends to decrease as coal charge rate or solvent/coal ratio increases whether creosote or decrystallized anthracene is used as the solvent. Milling crushability is unaffected by slurry preparation temperature. Content of residual moisture in the slurry decreases to 1% or less, when slurry preparation temperature is increased to 100 degrees C or higher. Liquefaction reactivity of the slurry shows slight dependence on slurry preparation temperature, when it is increased to 180 degrees C. (NEDO)

    Among the items of the Sunshine Project in fiscal 1981 for development of a solvent extraction and liquefaction plant, this paper describes the achievements in developing secondary hydrogenation. A small continuous hydrogenation device equipped with three reaction columns that can be filled with catalyst of 50 cc, and a dedicated testing room were designed, and orders were placed with manufacturers. The fabrication, assembly, delivery, installation, piping and wiring were all completed. The device passed a completion inspection based on the high-pressure gas safety assurance law in December 1981. After leakage due to gas and material oil was checked, a trial operation was performed, and verified of normal operation. A screening test was carried out on three kinds of commercially available and prototype catalysts before testing the SRC containing material for studying the secondary hydrogenation. The circulating solvent having a boiling point from 180 to 430 degree C (F56-01) was used as the test sample. In order to investigate the relationship between the kinds of solvent used for the SRC fraction and the secondary hydrogenation capability, solvents were made by treating the spent solvent F56-01. Trial manufacture was begun on the alumina based catalyst as a deliming catalyst, and on the red mud, bauxite and alumina based catalysts as hydrogenation and decomposition catalysts. (NEDO)

    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)

    The present Japan-China joint development project is intended to study liquefaction performance of different types of Chinese coals, select coal types suitable for coal liquefaction, and serve for enhancement in the coal liquefaction technologies employed by the Chinese side. Since a small continuous testing device has been installed in fiscal 1982 and begun with the trial operation in March 1983, the liquefaction test has been performed for about five years, and is scheduled to continue another three years. Chinese coals produced in seven provinces and two autonomous regions have been subjected to the coal type selection, on which discussions were given for liquefying reaction characteristics by using autoclave testing and small continuous testing devices. As a result, circulation tests were performed by the end of fiscal 1987 on five coal types, namely Beisu coal, Texgxian coal, Xianfeng coal, Shenmu coal, and Meihekou coal. Data were acquired during the circulation and at the equilibrium. Comparison of the results of tests on these five coal types with the results having been acquired from the 0.1-t/d BSU in Japan before modification verified the result being nearly reasonable.

In the coal injection operation, a 59-day slurry operation was carried out using Tanito Harum coal, which was for the evaluation of the reforming effect under the product reforming conditions, operationality, and liquefaction characteristics. A 37-day slurry operation was also performed using Chinese coal, which was intended to pursue improved cost performance and to collect the light oil fraction in the flow of reforming operation. In the operation for maintenance, investigations were conducted into conditions for hydrogenation in a 1-through operation involving the solvent hydrogenation process and the normal pressure distillation facilities and into the effect of pre-hydrogenation solvent properties, which aimed at grasping the effect of product oil reforming measures and their influence on operationality. In the survey of environments, the properties of wastewater from the liquefaction process using Tanito Harum coal were studied and toxicity evaluation tests were conducted for activated sludge.

    Among researches on solvolysis coal liquefaction technologies in the Sunshine Project in fiscal 1981, this paper describes the research on realization of solvolysis pitch hydrogenation equipment. In realizing a hydrogenation and decomposition reacting equipment for the second stage reaction process, it is important to stabilize operation by preventing coking and catalytic deterioration in elevated temperature zones. Therefore, a reactor of catalytic fluid system was assumed. Fiscal 1981 has fabricated and experimented a flow testing equipment for the purpose of acquiring data for realization of the equipment. A reactor that can deal with temperatures higher than 400 degrees C was installed in a 0.1-t/d continuously operating equipment. For selecting adequate operating conditions, an operation manual was prepared from the results of the cold model test and the fundamental test on hydrogenation and decomposition. The devices used were verified to have good operability. As the gasification rate increases when the reaction temperature is raised, resulting in reduced oil yield, it is necessary to keep the temperature lower than 430 degrees C. Increased pressure does not increase the oil yield as much as it increases hydrogen consumption, hence pressure of 200 kg/cm{sup 2} or lower is suitable. The secondary hydrogenation solvent requires no proton donation performance, and light fraction should be preferable. Catalysts were also discussed, and a clue to improvements was obtained. (NEDO)

    This paper explains the results of development of coal liquefaction technology under the Sunshine Project in fiscal 1980. As a part of the development of brown coal liquefaction technology, pulverization of the first-dehydration brown coal was technologically established, as were adjustment of slurry and equipment for the second-dehydration process. A 20kg/h high temperature in-oil pulverizer was designed, constructed and made ready for the studies. A high temperature mill was a wet type ball mill, 500mm{phi}(diameter) x 1,500 mm length and 2.2kw. Coal was fully pulverized even in a solvent such as creosote oil and anthracene oil freed from crystal, and was adjustable to a prescribed particle size distribution. The wet type slurry adjustment method offered prospects that solvent/coal slurry moisture could be controlled to a prescribed value. An analysis was made on the mill outlet gas and drain collection liquid at the time of high temperature in-oil pulverization, which provided knowledge of securing safety. An analysis was also made on the influence of the heating temperature rise of the mill on the strength, which provided basic data for examining the strength of the mill. Using brown coal as the raw material, slurry was prepared, which confirmed that the device had functions as planned. (NEDO)

    This paper describes the achievements in 1991 on studies on the bituminous coal liquefaction technology using a pilot plant. Based on the detailed design of the 150-t/d pilot plant, study problems and analysis items were reviewed, and a material balance acquiring method and a reaction column data analyzing method were discussed. Utilization of the liquefaction simulator was attempted. Efficient execution of the pilot plant operation study requires to have the basic and support study achievements reflected on the pilot plant operation, and clarify the roles to be played by the groups. Therefore, discussion items were compiled. The overall process plan for the design and construction was reviewed based on the plan discussed in fiscal 1990. Fiscal 1991 has launched common civil engineering constructions. The operation plans for the main four facilities in the pilot plant, which have been prepared in fiscal 1988, were continued of reviewing to cope with the situation of the decreased construction budget. The budget was reviewed again in fiscal 1991, which would present a prospect of starting the operation in fiscal 1995. Annual reviews on the basic operation plans for the main four facilities and the conceptions taken to date were put into order. The project management system was also expanded and re-arranged, including the information registration and retrieval system. (NEDO)

    Studies have been made for the purpose of analyzing solidification phenomenon of ground in relation to freezing construction method used in subway, water supply, and sewage constructions. Experimental studies have been carried out on solidification process of porous medium saturated with aqueous solution to discover influence of initial concentration of the solution and diameter of beads that constitute a porous medium. The experiment was performed by solidifying the porous medium sequentially from a side wall with lower temperature in a rectangular experimental tank with a height and a width of 100 mm filled with NaCl aqueous solution and beads. As a result, it was discovered that, if the initial concentration is low, the temperature difference is little between the upper part and the lower part of the experimental tank, and natural convection in the liquid-phase region is suppressed because of rising solidification temperature; the natural convection is suppressed in the liquid-phase region; and the boundary face between the mushy region and the liquid-phase region moves quickly. Further, the concentration rise in the liquid-phase region has slowed down despite that the solidification region is large enough. The smaller the mean diameter of beads, the faster the growth rate on the boundary face, hence the natural convection in the tank has been suppressed, and the growth rate on the boundary face has increased. In addition, the concentration stratification in the liquid-phase region does not expand, but is formed only on the bottom. 6 refs., 12 figs.

    This paper reports the study results on technological development for qualitative improvement of a-Si solar cells after initial degradation in fiscal 1994. On the fabrication technology of light-stable a-Si films, the film formation method possible to control combined hydrogen by repetitive formation/treatment was developed. The obtained high-quality light-stable a-Si film was featured by low defect density in a wide optical band gap range, and defect density of nearly 3 {times} 10{sup 16}/cm{sup -3} after light irradiation. The light degradation rate of the cell where the a-Si film was applied to i layer was relatively stable by 10% or less. The a-Si/a-Si double-layer tandem cell fabricated by this technology produced a high conversion efficiency of 10.5%. By applying {mu}c-Si material to photoactive layer as narrow band gap material, the cell with optical sensitivity even in long wavelength ranges more than 1000nm was obtained. The a-Si/{mu}c-Si double-layer tandem cell produced an initial efficiency of 8.0% and an efficiency after degradation of 7.5%. 12 figs., 3 tabs.

    This paper describes the achievements in development of brown coal based solvent extraction in the Sunshine Project in fiscal 1981. Element researches were performed to complement and support the development of a liquefaction technology for brown coal produced in Victoria, Australia by using a 50-T/D pilot plant. For the primary hydrogenation technology, a manufacturing experiment was completed by means of nine cycles using a brown coal balancing solvent in a 0.1-t/day bench scale test. Distribution of the formed materials, the solvent properties, and the SRC properties have become nearly constant after 5 to 6 cycles. A test using a batch type device was performed to derive the relationship among dissolution parameters, SRC recovery rates, and deliming rates by using different solvents. For the secondary hydrogenation technology, SRC being the heavy fraction in a primary hydrogenation system (+420 degrees C) was hydrogenated by using an Ni{center_dot}Mo based catalyst at 360 degrees C and 250 kg/cm{sup 2}. A prospect was attained that the processing is possible by using a fixed bed reactor. A test using a small continuous dehydration testing device was carried out by using creosote oil as the solvent and by varying the evaporator operating conditions. Dehydration rate of 90 to 95% was obtained. Discussions were given on selecting catalysts for the secondary hydrogenation of the fixed bed method, and on factors of activity deterioration. A secondary hydrogenation test reactor of the suspended bed method was completed. (NEDO)

    Research and development is started of materials for constituting a liquefaction reactor which is the primary apparatus in the coal liquefaction process. Tested in the basic research on the designing of alloys for the reactor are Cr-Mo-V-Ti based alloys prepared by adding V, Ti, and B to Cr-Mo based alloys presently in use as materials for pressure vessels. They are melted and 50kg test ingots of steel are prepared, and an alloy with a constitution of Low Si-3%Cr-1%Mo-0.25%V-0.02%Ti-0.002%B is selected. In the designing of alloys to serve as stainless steel overlay welding materials and in the development of basic welding technologies, studies are conducted in search for materials that exhibit excellent durability under the conditions of liquefaction reaction and for technologies in this connection. These are accomplished using a test device installed this fiscal year, which is capable of reproducing high-temperature high-pressure hydrogen atmosphere. As the result, basic technologies are acquired, which will enable the achievement of the goal. In the study of on-site production technologies using medium-size ingots as the materials, an 85-ton medium size steel ingot of a new chemical constitution of Low Si-3Cr-1Mo-1/4V-Ti-B is melted, and a shell which is 400mm in thickness and 2m in internal diameter is forged, and the shell is subjected to a property and performance qualification test.

    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.

    Liquefaction characteristics of coal specimens, collected from many locations across the world, are determined so as to make clear the correlations between coal type and liquefaction reactivity. Conducted for this purpose are the analysis of chemical structures of the specimens, liquefaction tests in an autoclave using various catalysts and medium oils, liquefaction tests in a 0.1t/d bench plant, investigation of the constituents of the generated oil and their separation, and the secondary stabilization treatment for the commercialization of the product. The reaction tower is kept under constant conditions, the state of the liquid mixture in the reaction tower is evaluated by tracking the flow of coal out of the reaction tower after switchover from anthracene oil to coal paste, the gas flow in the reaction tower is estimated by tracking time-wise changes in the concentration level of inert gas at the reaction tower outlet port, the inert gas having been injected in pulses into the reaction system operating under the reaction conditions. For the implementation of the above-mentioned steps, a system is designed and constructed for directly collecting samples from the vapor phase section in the reaction tower operating under given reaction conditions (temperature: 400-450 degrees C, pressure 150-300kg/cm{sup 2}), and experiments are conducted to collect gas/liquid equilibrium data in the reaction tower under the given reaction conditions.

    The basic experimental researches were carried out for coal liquefaction by solvolysis. The studied items include hydrogenation conditions for treating the primary liquefied products, asphalt, pitch and model solvents (e.g., anthracene oil) in the presence of a commercial catalyst, solvolysis conditions for finely divided, molten coal using a hydrogenation recycled solvent, hydrotreating solvents, analysis of solvolysis-liquefied products, and liquefaction capacity of fractionated solvents for finely divided, molten coal. The studied items for separation of minerals include settlement at high temperature of the solid residue from the first liquefaction stage, and changed coal particle size distribution as a result of the first-stage liquefaction reactions in the presence of a hydrogenation solvent. The experimental study results indicate that conversion of finely divided molten coal into asphaltenes and preasphaltenes is notably accelerated in the phase-II coal liquefaction process by solvolysis, when a hydrotreating solvent is used for the first stage solvolysis process.

    It is intended to extract patents related to the Sunshine Project, and identify movements in research and development as seen from the patent aspect. This paper describes the summary and technological trends in patents on the coal related new technologies disclosed during fiscal 1986. While the total number of patents was the same as that in the last year at 334 patents, the contents show marks of remarkable progress in several points. The first point is that the patent application fields are concentrated, where the majority is accounted for by patent applications in liquefying devices related to solvent, catalyst and reaction for the direct hydrogenation liquefaction in the field of liquefaction; preparation of CWM and surface active agent in the field of mixed fuels; and jet flow bed gasification furnaces in the field of gasification. The second point is that the patent application has increased in element technologies and system technologies based on actual records in each department, showing the marks of steady progress in the development stage. The third points is that the patent applications are systematized and performed in correspondence with issue points, which are the common trends among the applying companies. While this is thought because of technological levels in the companies having risen, the focuses of applications have become considerably clear. (NEDO)

    This paper describes the achievements at the Government Industrial Development Laboratory, Hokkaido in the Sunshine Project in fiscal 1990. Surveys were carried on different catalytic activities for co-liquefaction of various types of coals. The Ru system was found preferable in acquiring fatty family products of low boiling points. Reactions of co-liquefaction constituents do not progress independently, but have positive interaction. Adding Ru is effective in accelerating hydrogenation of condensed aromatic rings and hydrogenation of cleaving nucleus, but in view of the hydrogenating decomposition capability, the Mo-system may be better. In a liquefaction plant test, diesel oil was manufactured by reforming and improving the Yallourn coal light oil. However, the oxygen content was too high, aggravating the temperature distribution control in catalyst bed, and not having achieved the intended denitrification rate. Discussions were given on co-liquefaction of the depressurization residues of Cold Lake (CLVB[vacuum bottom])/Athabasca (ATVB) and Battle River coal. The CLCVB and ATVB were turned into lower molecules easily through hydrogenation treatment. The reaction characteristics reflected the characteristics of medium oil. Depolymerization of coal has progressed faster in ATVB. In the study on the engineering property values, discussions were given on behavior of solid particles in a bubble column, and gas hold-up of slurry. (NEDO)

    The relationship between coal properties and liquefaction or gasification characteristics was analyzed by using the analysis and test results and liquefaction characteristics in the coal data base. On liquefaction reaction, the close relation between an oil yield and coal constituent composition or a coal rank is well-known. Various multivariable regression analyses were conducted by using 6 factors as variables such as calorific value, volatile component, O/C and H/C atomic ratios, exinite+vitrinite content and vitrinite reflectance, and liquefaction characteristics as variate. On liquefaction characteristics, the oil yield of dehydrated and deashed coals, asphaltene yield, hydrogen consumption, produced water and gas quantities, and oil+asphaltene yield were predicted. The theoretical gasification efficiency of each specimen was calculated to evaluate the liquefaction reaction obtained. As a result, the oil yield increased with H/C atomic ratio, while the theoretical gasification efficiency increased with O/C atomic ratio. 5 figs., 1 tab.

    Development of a bituminous coal liquefaction technology (NEDOL method) can be judged appropriate as a national project in the comprehensive view with the 21st century just around the corner. It is a fact that this project has spent the national budget not in a small amount. There is no prospect of the technology to be put into practical use in Japan at the present time. The coal liquefaction technology is a technology required inevitably in the situation where shortage of crude oil supply may endanger the existence of a nation. Therefore, there is sufficient significance in having demonstrated the effectiveness of the NEDOL method which can be applied to a large number of coal types and expected of high liquefaction yield. The contents of the 'technological package' to be prepared are so demanded that its usefulness can be retained until the time of a demonstration plant design and operation will come in the future. It is also desired that the human resources and the testing devices will be kept ensured, and the technologies developed under this project will be maintained and expanded. The present technology has low necessity of immediately putting into practical use in Japan at the present time. However, the technology should be kept available for use at any time, and retained for use in an urgent situation. (NEDO)

    This report is the summary of the 'investigation results concerning development policy and position of various coal liquefaction processes in Japan'. The purpose of this investigative research is primarily to clarify the position of coal energy in the future energy supply, technologies of converting coal to clean fuel as the form of coal energy utilization most suitable for Japan, and the position of coal liquefaction in such converting technologies, and also to decide on the policy of R and D on coal liquefaction process in Japan at present. Accordingly, this paper investigates the status quo of various liquefaction processes including the coal liquefaction technologies for which R and D are conducted under the Sunshine Project; making analysis/assessment from such viewpoint as clean process as environmental safeguard and a precondition for coal energy utilization, technical problems concerning coal import and transportation, and suitability for the present energy consumption structure centering on oil; and further, examining the position of coal liquefaction in the general effective utilization of coal as organic carbonaceous resources in the distant future.

    Surveys are carried out on the current status of information control systems for development projects being performed or planned in developing coal liquefaction technologies. The conception for structuring a coal liquefaction database (CLDB) is made clear to manage comprehensively and utilize effectively the information in the systems. Section 3 investigated and analyzed the current status of data processing for experimental plants. The data for each experimental plant are processed individually. Therefore, it is preferable that the CLDB shall be provided with accommodating locations to receive respective data. Section 4 put into order the flows of operation and information in the coal liquefaction research, and depicted an overall configuration diagram for the system. Section 5 discusses problems in structuring this system. There is a large number of problems to be discussed from now on, not only in the technological aspect, but in analyzing the organizational roles of NEDO and commissioned business entities, and the needs of users. The last section summarizes the steps and schedule for developing this system. The development steps should preferably be implemented stepwise along the progress of the experimental plants, in such an order as the fundamental database, analysis database and engineering database.

    The operation of a 1t/d PSU (process support unit) was studied in the NEDOL coal liquefaction process. Modification was made, which involved the installation of a high-temperature/high-pressure sampling device for observing reaction and fluidity in the liquefaction reactor, a differential pressure measuring device, and a neutron attenuation-aided measuring device. Relative to coal injection, a 49.5-day and 49.3-day slurry injections were carried out using Tanito Harum coal, when impacts on the product yield and the operability of the unit were examined. A verification test was conducted for an improved hydrogenation catalyst, and liquefaction reactor characteristics were investigated. During a 19-day operation for the study of maintenance, newly installed equipment and devices were verified for function, and operating methods were probed into. In the survey of environments, characteristics were examined of the wastewater discharged from the Tanito Harum coal liquefaction process, and wastewater treatment methods were studied. The air, odor, and tar mist were examined with the PSU in operation, and the measured values were found to be below the management limits showing that its operation did not pose any problems relating to working environments.

    The removal treatment of free cyanide in waste water was tested by complexation with Fe(2) ion followed by alkaline chlorination and precipitation of residual iron cyano complex to study saving of sodium hypochlorite (NaClO) for alkaline chlorination. The complexation with Fe(2) ion was studied in batch treatment under the coexistence with zinc ion assuming plating waste water, while the relation between the complexation and effective chlorine consumption in alkaline chlorination was studied in continuous treatment. As a result, the effective chlorine consumption was greatly decreased by pretreatment, and a cyanic acid ion (CNO{sup {minus}}) concentration was also lower than that in conventional methods. In the case of free cyanide with lower initial concentration, the total cyanide concentration in final treated water offered sufficiently low values only by adding zinc salt, while in higher initial concentration, it reached 1 ppm or less through precipitation by adding a reductant together with zinc salt. 9 refs., 7 figs., 2 tabs.

    We report photo-generation of highly hydrophilic surface of titanium dioxide. The photo-induced hydrophilicizing is achieved by photo-generation of Ti{sup 4+} to Ti{sup 3+} at definite sites on the surface, resulting in preferential adsorption of hydroxyl groups on corresponding oxygen vacant sites. We also report the photo-generation of titanium dioxide amphiphilic surface on definite photo illumination condition. The unique character of this surface is ascribed to the microstructure of hydrophilic and oreophilic domain. The hydrophilic or amphiphilic titanium dioxide coating can be applied for antifogging mirror or glass and also self-cleaning paint for various industrial materials. Several commercial applications including antifogging automobile side-view mirror or self-cleaning exterior ceramic tile has been starting to hit the market. (author)

    This paper discusses effects of surface reaction on deactivation of excited molecular oxygen in {sup 1}{Delta}g condition. Gaseous oxygen containing excited oxygen generated by microwave discharge at a concentration of less than 1% is flown into several kinds of tubes to be measured such as quartz tubes (with an inner diameter of about 10 mm), and the light emitting intensity of the excited oxygen was measured upstream and downstream of the tubes to be measured (with in-tube pressure of 1 Torr or 2 Torr) to derive its concentration change. The surface reaction on the tube wall was regarded as a primary reaction, and the concentration change of the excited oxygen in flows in the round tube (attributable to the surface reaction) was analyzed. With respect to effects of tube wall materials on deactivation of the excited molecular oxygen, the surface deactivation probability in the case of using low-activity materials has decreased in the order of Pyrex, PVC, quartz, PFA and PTFE. The surface deactivation probability in the case of using a metallic material, SUS316L, was about 1000 times larger than that in the quartz. 14 refs., 7 figs., 1 tab.

    For the cleavage of carbon-chlorine connection and decomposition of benzene rings which are hazardous causes of the environmental pollutants represented by dioxins, the photolysis of gaseous phase chlorobenzene used as a model compound was made using KrF and ArF excimer laser. The decomposition is high efficiency, and ArF shorter in wavelength can be compounded twice-four times as fast as KrF. It was found out that in the system where oxygen exists, carbon monoxide, carbon dioxide, acetylene, hydrogen chloride, etc. are produced as decomposition products. From the results of the gaschromatographical analysis, chlorine compounds were detected as solid phase decomposition products. However, by the oxygen existence effect and laser shorter wavelength effect, the formation of polychlorinated aromatics was controlled, and chlorine compounds were made non-pollutant together with the composition. It was indicated that the environmental clean-up technology using laser is effective for making low-concentration environmental pollutants non-pollutant, and it is a method to clean up the environment which has a wide range of the application field.

    It was intended to darify long-term performance of a secondary hydrogenation catalyst used for about one year in a 50t/d brown coal liquefaction pilot plant built in Australia. A catalyst used for about 3,400 hours in the pilot plant was used to perform a life test of 7,800 hours in total to investigate the catalyst deactivation behavior, ashed metal and carbonaceous material deposition behavior, and changes in catalyst properties. A catalyst is considered to deactivate mainly because of deposition of carbonaceous materials on the catalyst in the initial stage of reaction and accumulation of alkaline metals (Na and K). The catalyst activity is estimated to reduce to about half the initial activity in about 1,000 hours, but it was found that the activity reduces and the properties change very little thereafter. From the fact that changes in selectivity to reaction associated with reduced activity and in product properties are small, and so are in the apparent activation energy, it was made clear that Cu-Ni-Mo/Al2O3 catalyst can be used for about one year. 3 refs., 9 figs., 1 tab.

    The secondary hydroprocessing process in the two-stage hydrogenating liquefaction equipment under development at Nippon Brown Coal Liquefaction Company uses a fixed bed system. To elucidate causes of catalyst activity degradation related therewith, catalyst used for about 1000 hours in a S -t/d pilot plant was collected to investigate deposition behavior of cokes and ashed metals and changes in catalyst properties. The catalyst is made of Ca-Ni-Mo/Al2O3, which was recovered from baskets placed in each layer in a reactor, washed in a predetermined manner, dried, and analyzed. In addition, in order to investigate remaining activity, 1-methylnaphthalene was hydrogenated, and deashed oil (DAO) was hydrocracked. The result may be summarized as follows: The major cause for the catalyst activity degradation is deposition of carbonaceous materials and ashed metals on the catalyst; and especially alkali metals (Na and K) were considered to be the major cause for the catalyst deactivation with time. 2 refs., 8 figs.

    With an objective to clarify causes of deactivation of catalysts used in brown coal liquefaction process, discussions were given on catalysts recovered after use of 3400 hours as to their behavior of accumulating ash metals and carbonaceous substances, changes in the catalyst properties, and remaining activity. The catalysts used were Ca-Ni-Mo/Al2O3. Metals in the catalysts were quantitatively analyzed using ICP emission spectral analysis and atomic absorption analysis, and the C-amount using a CHN coder. The surface area was measured using the BET process and the pore volume using a porosimeter. The remaining activity in the used catalysts was evaluated by modelled hydrogenation of 1-methylnaphthalene. The results may be summarized as follows: Metals deposited on the catalysts are Mg, Ca, Fe, Na, Si and K, identically with the case of 1000-hour used catalysts; carbonaceous mass on the catalysts would range from 10% to 15%; the catalyst surface area and pore volume decrease with increasing carbonaceous matter accumulation; and hydrogenation activity was found decreased in the model hydrogenation, which should be because the activity has correlation with alkaline metal accumulation, and the metals enter fine pores to poison activity points. 3 refs., 6 figs.

    In polymerization involving a rapid exothermic reaction, it is necessary for the generated heat in this operation to be removed from the reactor by a cooling coil or jacket to control the reaction temperature. But, fluid in the reactor is gets stagnant as the reaction proceeds, because the viscosity is increasing due to monomer convection, therefore the reactor often has induced uneven temperature distribution. In this work, radical addition polymerization was carried out in a reactor using several types of impeller-paddle, anchor, helical screw and helical ribbon, Under these conditions, local temperature distribution was measured in detail using our prototype real-time and multi-point temperature measuring instrument which is able to measure simultaneously changing temperature at local positions via many thermocouples. As a result of these experiments the condition of changing local temperature and the obtained polymers were found to be related to the type of impellers. We found the high temperature areas in the reactor produced polymers composed of undesirably short chain length molecules. As the cooling condition of the reactor was found by measuring local temperature, we could also find a suitable position for the control sensor of temperature for lowering local higher temperature in the polymerization under the set value. 15 refs., 8 figs., 2 tabs.

    In radical additional solution polymerization, the viscosity increases with reaction progress. It is important to evaluate beforehand the cooling capacity of the reactor, which worsens with the process. In this study, a stirred batch reactor with both a paddle and a helical screw impeller were studied, and measurements were made for the dynamic changes of the film heat transfer coefficient of the cooling coil with progress of the polymer reaction. We found the change could be evaluated by the calculating heat balance of the generated heat, the viscous dissipation energy and the sensible heat change under conditions of monomer conversion and changing viscosity. 11 refs., 7 figs.

    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.

    A solar chemical heat pump is intended to attempt multi-purposed effective utilization of solar energy by raising low temperature solar heat of about 100 degC to 150 to 200 degC by utilizing chemical reactions. The chemical heat pump under the present study uses a 2-propanol (IPA)/acetone/hydrogen system which can utilize low-temperature solar heat and has large temperature rising degree. It was found from the result of experiments and analyses that IPA dehydrogenation reaction can improve more largely the heat utilization rate in using a falling-liquid film reactor than using a liquid phase suspended system. As an attempt to improve further the heat utilization rate, this paper reports the result of experimental discussions on inclination angles of a reaction vessel and feed liquid flow rate which would affect the fluid condition of the liquid film. As a result of the experiments, the initial deterioration in the catalyst has settled in about 15 hours, and its activity has decreased to about 60% of the initial activity. It was made clear that the influence of the inclination angle of the reaction vessel on the reaction is small. 5 refs., 7 figs.

    Research and evaluation was performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the basic characteristics of photochromic materials, a non-destructively readable recording system was proposed and demonstrated, highly durable and high-functional photochromic compounds were developed, and a number of material design guidelines were accumulated to realize characteristics required in light-beam recording. With regard to development of the photochromic materials, realization of photochromic thin films that can record wavelengths in multiplex manner has become more realistic. For elucidating basic characteristics of PHB materials, a method for evaluation from a number of directions including the time method for photon echo was established in addition to the conventional frequency recording characteristics. Regarding the elucidation of the PHB phenomenon, demonstration was carried out on intermediate zone structure control in diversified material systems including living organism substances, where a large number of findings were accumulated.

    This is a prompt report. These days the importance of acquiring knowledge about the structure from the lower crust down to the upper mantle is often discussed with reference taken to Hyogo-ken Nanbu Earthquake. The Hidaka collision belt where the lower crust is exposed on the surface is a rare phenomenon in the world and has been the subject of seismic survey. As a part of the survey, experiments are conducted by the use of vibrations produced by Vibroseis and dynamite sources. Every one of the shot records (20-second record) from the two types of vibration sources contains a clear echo in the vicinity of 16 seconds supposedly from a level deeper than 40 kilometers, not to mention reflections from shallow levels. Although some studies have to be conducted before the reflecting geological boundary (possibly the upper mantle) of the echo near the 16-second point can be identified, yet this is probably the reflection from the deepest level ever obtained in the seismic reflection survey conducted in Japan`s land area. It is proved by this experiment that vibration from a vibrator can reach as far as that from explosion if the vibrator specifications are rightly chosen. 4 refs., 3 figs.

    Research, development and evaluation were performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the mechanism of light deterioration reaction of photochromic molecules, it was disclosed that 6-nitrospirobenzopyran has the light deterioration caused from the excitation triplet state. This disclosure presents a possibility of preventing the light deterioration. New derivatives that show photochromism were synthesized, and thin films were produced by using the LB process. This indicates a possibility of producing the photochromic materials as the high multiplex recording material. With regard to PHB materials, an evaluation technology having spectrum resolution of the world's highest level was established and measurements were performed. Hole formation was verified for the first time in the world at the temperature higher than the liquid nitrogen temperature by using a PHB material of ionic porphin/polyvinyl alcohol systems. This verification indicates a feasibility of practically usable PHB materials. (NEDO)

    TiC-TiO{sub 2} composite powders were prepared by in-flight oxidation of titanium carbide powder in RF induction thermal plasmas. Original titanium carbide powder of 20 - 38 {mu}m in particle size was axially injected into the center of argon-oxygen plasma. The powders were partially spheroidized and evaporated through the plasma treatment. X-ray diffraction of plasma-treated powders showed the formation of titanium dioxides, both rutile and anatase phases. The phase content of the plasma-prepared powders strongly depended on the plasma conditions, such as the plasma generating pressure and the oxygen flow rate in plasma generating gas. Especially, the increase of oxygen flow rate in plasma gas gave rise to the increase of heat transfer from plasma to powder particles, exothermic heat of oxidation reaction and cooling rate of plasma, giving the increase of spheroidization ratio, formation ratio of titanium dioxides, and content of anatase phases.

    The reactive sintered compacts of Ti-W-Cr-B mixed powders were manufactured by a pulse electric current technique. Identification and characterization of the resulting boride phase were done using EPMA, XRD and other methods. The density of the sintered compacts rose rapidly with sintering temperature up to 1,773 K, at which temperature the relative density was 94%. Above this temperature, the density rose only slightly with increasing sintering temperature. The borides of Ti and W were synthesized from mixed metal powders by this method. The type of boride formed and its composition depended on sintering temperature. Compacts sintered at lower temperatures consisted of WB{sub 2} and TiB{sub 2} phases, but at the highest sintering temperature, 2,173K, the main phase was (Ti, W, Cr)B{sub 2} solid solution, in which W and Cr were dissolved in TiB{sub 2}. There was also a very small amount of {beta}-(W, Ti, Cr)B phase. By annealing compact sintered at high temperature, the (Ti, W, Cr)B{sub 2} solid solution phase decomposed and the amount decreased.

    An ultrafine iron particle preparing process was developed, which wses gaseous phase pyrolysis in magnetic field of iron pentacarbonyl, Fe(CO){sub 5}, based on the fact that Fe(CO){sub 5} has peculiar characters that its boiling point is as low as 103{degree}C, and starts decomposing in a low temperature zone of 100{degree}C or lower. Vaporizing and introducing into a reactor an fe(CO){sub 5}, andPyrolyzing it at 200-600{degree}C while being diluted with nitrogen and applied with a magnetic field produced uitrafine iron particles of a necklace-like chain comprisinh primary particles having diameter of 15 to 25 nm with 10 to 40 of them linked in a straight chain. It was found that the specific surface area is 30-50 m{sup 2}/g, with the diameter converted from the specific surface area being relatively close to the average diameter obtained from TEM photograph, and that the particle has few pores. Magnetically the iron powder has a coercivity of 123-131 KA/m and a specific saturation magnetization of 120-140 Am{sup 2}/kg, and is expected to be applied as a high density magnetic recording medium. 5 refs.,8 figs., 3 tabs.

    With the purpose of converting solar heat energy to an industrial heat energy, an examination was carried out empirically on the case of using a heteropoly-acid photo catalyst for the decomposition reaction process of 2-propanol. The experiment was performed in Florida Solar Energy Center, in the U.S.A.. The device for the experiment was constituted of a reaction part, distribution manifold for feeding from the lower part of the reaction part a 2-propanol solution for which a photo catalyst was suspended, storage tank served also as a gas-liquid separating container, and circulating pump. Silica-tangstic acid was used as the photo catalyst. In an outdoor experiment using solar radiation, the quantity of inclined global solar radiation was 530-950W/m{sup 2} in clear days and 100-600W/m{sup 2} in cloudy days, with temperatures between 17 and 26{degree}C throughout the experiment period. In addition, an indoor experiment was also conducted using an artificial light source (UV light). As a result of the experiment, the energy conversion efficiency was at most about 1% of incident UV light, a low figure compared to a heat utilization ratio of approximately 15% with a thermal catalyst. 6 refs., 8 figs.

    To establish the inhomogeneous solid combustion control technology, effects of the strong magnetic field on the solid combustion were examined. When applying the sufficiently strong magnetic field, it is possible to control the air flow in combustion field by utilizing the force applying to constituent oxygen with large susceptibility. Based on this possibility, combustion experiments of expanded polystyrene plates were conducted between the magnetic poles of electro-magnet having the maximum flux density of 1 T and the maximum magnetic field gradient of 0.5 T/cm. To observe the effects of magnetic field without the effects of natural convection, combustion experiments of acrylic sheets were conducted between the magnetic poles of electro-magnet having the maximum flux density of 0.6 T and the magnetic field gradient of about 0.1 T/cm under the microgravity conditions between 10{sup -4} and 10{sup -5}g using a microgravity test facility. Consequently, prospective combustion results could be obtained, in which the force of flame received from the magnetic field is almost equivalent to the buoyancy of flame. It was demonstrated that combustion can be controlled by the magnetic field. 1 ref., 3 figs., 1 tab.

    Selective oxidation of lower alkanes by use of heteropolymeric compounds is studied. Alkanes are activated on Cs2.5H0.5PW12O40 serving as catalyst, and their activity and selectivity improve when the catalyst is developed into a dual function catalyst in which Cs and Pt are combined. A success is reported of the synthesis of a heteropolymeric acid in which two molecules of the coordination element wolfram are replaced with a transition metal of the first period, on which acid the oxidation of cyclohexane is enhanced. Cs2.5Ni0.08H1.34PVMo11O40 as a metal/heteropolymeric acid dual function catalyst enables the direct oxidation (9% recovered at 340{degree}C) of isobutane into a methacrylic acid, which is attributed to the harmonious coordination of the oxidizing work of the catalyst and acidity. It is possible to oxidize propane into the acrylic acid, but not ethane into the acetic acid. In the case of Pd/Cs2.5H1.5PVMo11O40, the formic acid, methanol, etc., are produced upon addition of hydrogen to the system. This reaction in the hydrogen/oxygen system is supposed to take place via activated oxygen seeds as in the case of oxidation by hydrogen peroxide. 10 refs.

    The molten salt system electrochemical cycle was proposed to reproduce pure Al from scrap Al. The cycle is composed of production of rough AlCl3 by chlorination of scrap Al, refining of rough AlCl3 mainly by sublimation, and electrolytic reproduction of pure Al from refined AlCl3. In production of AlCl3, the Al-Cl2 molten salt system cell composed of anode dissolution reaction of Al and cathode reduction reaction of chlorine gas can generate electric power for the electrolytic reproduction. Chlorine gas can be recycled as anode product. Various experiments were carried out to improve molten salt system cells. In analysis of cell output, voltage drop from open circuit voltage was divided into that due to electrolytic bath resistance, and that due to reaction resistance. The electrolytic bath resistance could be determined from transient characteristics of voltage change just after cutoff of output current. The product of the obtained reaction resistance and a meniscus length was constant regardless of a meniscus length, and useful to predict scale-up cell performance. Output characteristics dependent on meniscus position were also obtained. 16 refs., 11 figs.

    To effectively utilize unused sea weeds having ingestion obstructing activities for feed, the treatment by oxygen added enzyme has been investigated. Undaria pinnatifida was pasted and solidified with agar, to prepare the standard feed. Individuals of Holiotis discus hannai Ino were bred in the cistern. Extracts from ten kinds of sea weed distributed in the Sanriku Coast were added to the feed, which were compared with the standard feed to determine the ingestion obstructing activities. A testing method using cellulose painted aluminum sheet was also employed. All of the extracts from sea weeds having the ingestion obstructing activities exhibited the strong phenol reactions. The sensitivity of individuals of Holiotis discus hannai Ino depended greatly on the derived species and the chemical structures of phenolic substances. The {alpha}-hydroxymuconic acid semialdehyde (HMS), an enzyme decomposition product of catechol, provided no ingestion obstructing activity, and showed a little ingestion accelerating activity. This was considered to become ingestible through the biodegradation of phenolic substances. The HMS, a decomposition product of catechol 2,3-oxygen added enzyme derived from the petroleum decomposition bacteria, was prospective as a highly functional compound synthesizing material. 10 refs., 34 figs., 10 tabs.

    For effective use of unused seaweeds, efficient search of available microorganism systems and their conversion for effective use were studied. Since generally found Phaeophyceae includes a large amount of polyphenol such as phlorotannin, it is refused by plant-eating animals, inhibits protein from effective absorption, and is inadequate for livestock feed because of tasteless. Bacteria Rhodococcus sp. PG7-2 was isolated which can be effectively increased using phloroglucinol as substrate. Participation of oxygen- adding enzyme was suggested in the initial stage of decomposition which adds molecular oxygen to aromatic rings. In the experiment using combinations of extracted and isolated enzymes and various coenzymes, no significant decomposition was observed. Since phlorotannin of Phaeophyceae is the polymer which shows a matrix-like extent through difficult-to-decompose bond such as biphenyl bond and phenyl ether bond, its decomposition by one kind of bacterium is extremely difficult. Search of decomposition systems of polymer remains as the future issue. 15 refs., 30 figs., 5 tabs.

    The present developmental conditions and issues of new energies are systematically arranged for effective promotion of their diffusion. One hundred and forty six general waste power generation facilities of 558,000kW are in operation in 1995, and among them 89 facilities supplies 1,080 GWh to power companies. 50 industrial waste power facilities of 247,000kW are in operation. 20,000 solar systems and 180,000 hot water heaters are in operation in 1995. Commercial geothermal power generation facilities of 490,000kW and private ones of 36,000kW are in operation. Introduction of expensive clean energy vehicles is making very slow progress.

    The R and D program was implemented for a hydrohoist system, with the objectives to reduce wear and power requirements in the direct hydrogenation type coal liquefaction plant. Direct hydrogenation, operating at elevated pressure in the presence of catalyst, is suitable for liquefaction of coal to produce light liquid products, which are in great demand. However, there are many mechanical problems to be solved, because the plant is operated under very severe conditions. The proposed hydrohoist system combines supply of the feed slurry with the let-down step for the slurry effluent as the product of the high-pressure system, to save energy by recovering power from the effluent slurry and, at the same time, reduce wear of the pumps and let-down valves, for the direct hydrogenation plant operating at 150 to 300 kg/cm{sup 2} in the presence of catalyst to liquefy coal. Such a system has been already commercialized for transferring coal and other minerals. In the FY 1980, basic tests are conducted using a small autoclave, to extract the problematical points for the test system. The results serve as the bases for designs and construction of the basic test system by which the hydrohoist system is to be studied and evaluated. (NEDO)

    The industrial capability and construction capability of Australia are surveyed in relation with the project of constructing a brown coal liquefaction plant there. Australian heavy industry is conspicuously advanced in the field of mining machinery involving coal, iron ore, and other mineral resources. On the other hand, in the fields of general-purpose machinery for plants and of civil engineering machinery, it is behind other countries in terms of technology and cost because of the small market. When an industrial project is implemented in Australia, consulting firms, engineering contractors, etc., operate independently from each other, and the project is propelled forward under a perfect specialization system. Labor-related problems in the civil engineering and construction industry are the recruitment of laborers which is difficult and the delay in and suspension of construction due to labor disputes that take place very frequently. In Victoria State where a brown coal liquefaction plant is under construction, the availability of laborers specializing in construction is rather higher than in other states, and there is no important problem in this respect. One cannot be too prudent in Victoria State, however, since it includes a region which is the most notorious in Australia in terms of labor-management dispute. (NEDO)

    Hydrogen gas as material is produced mostly by steam reforming of hydrocarbons, and includes a considerable amount of impurities such as carbon dioxide, nitrogen and oxygen. The concentration of impurities in the refined gas is approximately 1ppm. In the liquefaction process of hydrogen liquefaction plant, the gases entering the low temperature portion near the free expansion valve (J-T valve) are mostly oxygen and nitrogen. When oxygen is solidified, attached, accumulated near J-T valve, it incurs a possibility of exploding for reason of impact force, etc. by contact with the valve portion. A mixture of hydrogen and oxygen ignites at the minimum value of approximately 0.02 milli-joule, and therefore it has great danger of explosion. As viewed from a point of danger prevention, there is a possibility of explosion when the hydrogen-oxidizing agent mixture is formed. Accordingly, it is necessary to conduct an experiment for confirming the explosion at J-T valve portion. From viewpoints of prevention of explosion accident and running operation, it is necessary to experimentally grasp the definite allowable oxygen concentration. Further, it is necessary to establish a technology to continuously and accurately measure the concentration of trace impurities in hydrogen gas. (NEDO)

    With an objective of putting into practical use the wavelength multiplex recording system applied with the PHB phenomenon, research and development has been performed on material systems making high quality hole production possible at high sensitivity and high density. This paper summarizes the achievements in fiscal 1989. In the discussion of PHB materials, measurements were performed on the triple state of zinc, magnesium, copper and iron complexes of tetra-phenyl porphin and the triple state spectra by using the flash decomposition method in order to develop new photo-gate type material systems. Correlation was discovered between the free energy change in the reaction and the PHB reactivity from the result of the experiments, whereas important findings were obtained for designing the photo-gate type PHB material systems. In the discussion of the wavelength multiplex recording, an optical system was designed and fabricated to perform scanning and detection on sample surface by using laser beam squeezed to a diameter of 100 {mu} m. Discussions were given on the wavelength multiplex recording, position multiplex recording, and high-speed recording using this optical system. As a result, position multiplex holes were produced successfully by using the laser beam squeezed to a diameter of 100 {mu} m on four different positions on the sample surface, when the tetra phenylporphin derivative was used.

    As a result of search for systems which have aggregate structures, the displacement reaction products of Ti with CoO or NiO are found to have aggregate structures in which the produced oxides and metals are entangled with each other. The displacement reaction of Ti with CoO or NiO is investigated at the temperature of 1273K. In the reaction of either couple, aggregate products are produced, and reacted layer is observed in the TiO2 matrix wherein Co or Ni phases are three dimensionally entangled in finely dispersed state of micron order. 2 layers of cavitated and dense TiO2 layers are found in the reacted layer. The thicknesses of the reacted layer are not constant according to locations, but thick portions are grown obeying the parabolic rate law. As a result of the study on the possibility of fabricating cermet by the reaction between powders, finely mixed characteristic structures are found to be easily obtained using systems which can produce aggregate structures. 24 refs., 9 figs.

    It is known that infrared reflection absorption spectroscopy (IRAS) on semiconductor or insulator surfaces becomes practicable by using buried metal layer (BML) substrates, in which the metal thin film is buried order semiconductor or insulator films. In this work, IRAS has been measured for Langmuir-Blodgett films deposited on the BML substrate with SiO2/Al/Si(100) structure and the observed spectrum intensity has been quantitatively compared with the calculation assuming the ideal multilayer structure for the BML substrate. The BML-IRAS using CoSi2 has been adopted to the detection of SiHn on the Si (100) substrate during synchrotron radiation (SR) stimulated Si2H6 gas source molecular beam epitaxy. It has been found that SiH2 and SiH3 on the Si (100) surface are easily decomposed by SR, but SiH can`t be decomposed. From these experiments, it has been concluded that the BML-IRAS is an useful in situ observation technique for the photo-stimulated surface reactions. 26 refs., 9 figs.

    For the purpose of reducing CO2 emitting together with the consumption of fossil fuels, study was conducted on the use of CO2 by converting it to chemical substances such as methanol, etc., and the FY 1999 results were outlined. In the development of the CO2 separation membrane technology, data were obtained on effects of scaling-up by module with a membrane area of 4.9m{sup 2} and on design conditions. Further, in the experiment using mock exhaust gas, it was confirmed that the performance had been kept up for 3,000 hours or more. In the development of catalytic hydrogenation technology, the basic data for enlargement were accumulated. Moreover, the activity stabilized about 18,000 hours was confirmed, and the catalytic life was estimated at more than 3 years. In the development of large quantity hydrogen production/supply technology, assembly/operation of 7,500cm{sup 2} x 6 electrolytic cells were conducted, and it was confirmed that the hydrogen production capacity per cell was 3Nm{sup 3}/h. The final target for enlargement was achieved.

    In a flow system for vapor/solid catalytic reactions, there is a concentration distribution along the external catalyst surface, observed in the vicinity of the surface. Change in the reaction rate constant is followed for the case where the concentration distribution varies by flow. A 2-dimensional numerical model in which flow field and property conditions are simplified is used to analyze the change on the assumption that high-activity and low-activity sites are regularly distributed over the external catalyst surface. The transport equations for the reactants are numerically solved for given flow fields. It is found that the concentration distribution shape and equivalent reaction rate constant are almost the same as those in a stationary system at Pecret number of around 10 or lower, the concentration distribution gradually becomes uniform whereas equivalent rate constant increases as flow rate increases at Pecret number in a range from around 10 to 10{sup 6}, and they are almost constant at Pecret number beyond around 10{sup 6}. 3 refs., 11 figs., 1 tab.

    Molibdophosphoric acid (PMo) reacts with malachite green (MG{sup +}) to form a colored ion associate (MG{sup +}- PMo) in an acidic solution according to the formula : HMG{sup 2+}+H{sub 3}PMo{sub 12}O{sub 40}{yields}(MG{sup +})H{sub 2}PMo{sub 12}O{sub 40}+2H{sup +}. A protonated form HMG{sup 2+} is yellow (the absorption mximum at 446 nm), whereas the ion associate MG{sup +} is blue green (the absorption maximum at 650 nm). MG{sup +} is found to accelerate the formation of PMo. Water-miscible organic solvents such as methanol,ethanol and propanol also accelerate the formation of PMo as well as the formation of MG sup + - PMo. Some anionic surfactants decelerate the reaction, however, contribute to the suppression of the baseline drift in a flow injection analysis (FIA). By the use of the proposed reaction accelerator and surfactant. a highly sensitive FIA system is established for,orthophosphate up to the range of several ppb. 16 figs.. 11 refs.

    With an objective of creating ultra-high density organic photo recording elements for photon mode recording and rewritable wavelength multiplex recording by utilizing control of association status of photochromic compound, research and development has been performed. This paper summarizes the achievements in fiscal 1989. In developing the materials, verification was made on effectiveness of the newly structured positive polarity model. The method was used to attempt synthesis of four kinds of new spiropyrane, among which it was discovered that BSP1822 forms J-association complex in the long wavelength region. In the thin film forming technology, the J-association complex of BSP1822 was stabilized successfully in the film mixed with bi-molecular film forming material. In order to develop a technology to form dry photochromic thin films, an organic molecular beam epitaxial device and a thin film structure analyzer were introduced. In the elucidation and research on fundamental properties, discussions were given on properties of the SP1822LB film revealed by the steady-state light and laser pulse light. Furthermore, the molecular orientation of the SP1801 on the air-water interface was investigated, and molecular models on the air-water interface were considered. (NEDO)

    With an objective of establishing the fundamental technologies related to photo reactive materials that can be used for ultra-high density recording, high-resolution indication, and photoswitches by controlling structures and association status of molecules by using actions of light, research and development has been performed. This paper summarizes the achievements in fiscal 1989. In the research of synthesis and evaluation of PHB materials, a possibility was verified to form holes at temperatures higher than the liquid nitrogen temperature on all the materials in which six kinds of ionic porphin derivatives were dispersed into polyvinyl alcohol. Stability of holes in the tetra-alkyl pyridinium porhpn/polymer system was evaluated, the hole half-width was measured accurately by using ring die laser, and the hole forming characteristics were evaluated by means of high-power density and brief laser light irradiation. In search of new guests, a two-photon absorption spectrum measuring instrument was assembled to measure samples having zinc tetra-phenylporphyrin derivative as the guest. In addition, hole formation was discovered in samples having indomethylene based coloring matter as the guest. (NEDO)

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

    Research and evaluation was performed with an objective of establishing the basic technology related to light-reactive materials that control the structures and status of aggregation of molecules by using actions of light, and can be used for ultra-high density recording, high resolution indication and light switches. In elucidating the basic characteristics of photochromic materials, a non-destructively readable recording system was proposed and demonstrated, highly durable and high-functional photochromic compounds were developed, and a number of material design guidelines were accumulated to realize characteristics required in light-beam recording. With regard to development of the photochromic materials, realization of photochromic thin films that can record wavelengths in multiplex manner has become more realistic. For elucidating basic characteristics of PHB materials, a method for evaluation from a number of directions including the time method for photon echo was established in addition to the conventional frequency recording characteristics. Regarding the elucidation of the PHB phenomenon, demonstration was carried out on intermediate zone structure control in diversified material systems including living organism substances, where a large number of findings were accumulated.

    Considerations were given on the spark generating mechanism of graphite particles in molten salt polysulfide through experiments on Japanese sparklers. The firework composition mixed consisted of two kinds: KNO{sub 3}, S, amorphous carbons, charcoal and lamp black, and K{sub 2}CO{sub 3}, S, charcoal and lamp black. The main constituent in fire balls is molten salt polysulfide. The O{sub 2} generated from combustion oxidizes C and S, whereas the generated K{sub 2}CO{sub 3} reacts with S to produce K{sub 2}Sn. In the KNO{sub 3} system, the calorific power reaches the maximum with lamp black contained at 10-15%. This is thought because the K{sup +} expands the space between the graphite crystal layers making the oxidation to take place more easily into their inner sides. On the one hand, the calorific power reduced with the lamp black at more than 16% would be because the lamp black clogging the crystalline spaces restricting the oxidation. It is thought that condensation and decomposition of micro graphite crystals occur simultaneously in the fire balls. It is also believed that the micro graphite crystals jumped out as a result of gas pressure from inside the crystals generated with the progress of oxidation break off at once because of the resistance of air together with the effect of the K{sup +} in the salt polysulfide (mutual separation of each layer). 9 refs., 6 figs., 1 tab.

    Research was conducted on conversion of coal to petroleum for the purpose of securing substitute liquid fuel. Recovery of hydrogen from the waste gas from the conversion process was explained, as were the conversion results from various coals produced in Japan. In coal liquefaction researches with the aim of manufacturing artificial petroleum, a report was made on each of the researches, i.e., the experiment results of coal liquefaction using various catalysts, manufacture of hydrogen by water gas reaction, catalytic action against coal paste, action of mixed oil and pressure against coal paste, result of hydrogen adding test for coal paste using an intermediate scale device, test result of secondary hydrogen addition for coal liquefied oil, and the test result of continuous secondary hydrogen addition for the liquefied oil. In the manufacture of fuel oil by hydro-cracking of coal or tar, a report was made on high pressure liquid phase hydrogenation of coal using a continuous testing device. Aromatic chemicals useful as chemical materials are supposed to be obtained by cutting inter-polymerized-unit bonding to make low molecules from the chemical structure of coal, removing surrounding radicals and simplifying it. A report was also made on the experiment of manufacturing coal chemicals by combination of high pressure liquid phase hydrogenation and hydro-dealkylation. (NEDO)

    Together with the progress of technology development, policies for the introduction/promotion of new energy technology are being developed such as promotion of the commercialization development, revision of the law system, and expansion of the subsidy system for promotion. To push the introduction/promotion forward more effectively, it is necessary to arrange various kinds of data comprehensively/systematically and to make them the basic data for contribution to the spread/education. As to the six fields of the waste power generation, solar heat utilization, geothermal power generation, clean energy cars, coal liquefaction, and coal gasification of the technology fields of new energy, this report collected/arranged the data made public recently in terms mainly of the following: trends of the introduction in Japan and abroad, policy/law/subsidy system in Japan and abroad, cost, system outline, basic terms, a list of the main affiliated companies and groups, and the nation's outlook for energy introduction and policies of each new energy technology in Japan and abroad, and the trends.

    The depression of the reaction between SiC and Ni, by adding TiO2 powder in spraying powder which has caused uniform dispersion in spray coating and reduction of TiO2 by the reaction during spraying, was studied. The mass ratio of the mixed components has been, SiC:Ni:TiO2=3:2:1. The spray coating was examined by electron prove microanalysis as well as X-ray diffractometry, centering mainly to the SiC-metal interface reaction. The formation of Ni-Si compounds have been depressed by the addition of TiO2 to spraying powder and by using plasma gas containing H2. Reason for this has been that the TiC formed in the SiC-Ni interface has depressed the reaction at the SiC-Ni interface. Further, TiO2 is reduced during spraying, and TiC is thought to be formed by the reaction between Ti and SiC or reaction between TiO2 and SiC. 8 refs., 6 figs., 1 tab.

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

    Full Text Available La diffusione del pentecostalismo e la crescita degli aderenti ha assunto negli ultimi decenni dimensioni considerevoli che ne hanno fatto il movimento cristiano a più altro tasso di crescita a livello mondiale. Sebbene conosca una sua diffusione anche nelle aree rurali, è in quelle urbani che conosce uno sviluppo maggiore. Tra i fattori che ne hanno favorito la diffusione vi è certamente la flessibilità dell'idioma pentecostale che permette di adattarsi ai vari contesti locali. Diversi studiosi hanno evidenziato come versioni oggi più in crescita del pentecostalismo presentino nella dottrina, nelle predicazioni e nelle pratiche elementi coerenti con la prospettiva neoliberista oggi egemonica in larga parte del pianeta. Partendo dagli articoli presenti in questa sezione, il contributo intende riflettere su queste questioni, concentrandosi principalmente sul fenomeno per come si presenta nelle aree urbane.

    As a famous historian and Oriental history scholar in modern Japan, Ikeuchi Hiroshi made great achievements in his life, especially in the fields of Manchu history and Korean history. He is the pioneer who studied Japanese history and Oriental history through new methods of historical research in Europe and America. His ideas of ' doubt ' and ' distinguishment ' towards historical materials in "Studies in the Ancient History of Japan" provided guides for historical research. However, there were some questions in the book as well, because of the times ' and personal limitations. For example, both "Nihon Shoki" and the national power of Japan in fourth century lacked enough textual research on annals.%日本近代著名的历史学家、东洋史学家池内宏在《日本上古史研究---日鲜关系与日本书纪》中体现出的对史料的质疑与辨伪的思想,对史学研究具有重要的指导作用。但由于时代及个人局限,书中同样存在一些问题。如对《日本书纪》中纪年考辨不足,对四世纪日本国力考辨不足等。

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

    Directory of Open Access Journals (Sweden)

    Catharina Blomberg

    2003-01-01

    Full Text Available The earliest written records extant in Japan were compiled during the Nara period (710-781 A.D.. They are the Kojiki, "Record of Ancient Matters", 712 A.D.; the Nihongi or Nihon Shoki, "Chronicle of Japan", 720 A.D.; and the Many ōshū,"Collection of a Myriad Leaves", an anthology of poetry first published in 759 A.D. but also containing material from the Asuka period(ca 500-700 A.D.. Prior to these writings, the only existing evidence of practices which may be defined as rites of passage is archaeological. From the Neolithic Early Jōmon period (4500-3000 B.C. there are indications of a systematic extraction of teeth among a sizeable proportion of the population, the ratio being about 70 per cent males and 30 per cent females, with considerable regional variations (Blomberg 1990: 243. In its most drastic form this comprised the removal of the canines and incisors of both maxilla and mandible. This kind of mutilation eventually came to include an equally systematic filing down of the maxillary incisors into a fork or trident shape, with examples of both practices in the same individual. From the evidence of burnt clay figurines dating from the Jōmon as well as theYayoi period (ca 250 B.C.—ca 250 A.D. it appears that some kind of facial adornment existed. Whether this took the form of scarring, tattooing or painting is of course impossible to ascertain, but it may have been another means of indicating individual distinction or social position

    Directory of Open Access Journals (Sweden)

    Elisabetta Biffi

    2015-09-01

    Full Text Available Il presente contributo intende riflettere sull’utilizzo di una tecnica artistica, il collage, all’interno della formazione degli insegnanti e degli educatori. Si tratta di una differente modalità di azione da parte dei formatori che è inserita nell’ambito dell’art-based research (McNiff, 2008, e dell’arts-informed research (Cole & Knowles, 2008. Per comprendere in modo approfondito questa scelta è necessario conoscere la nascita di questa tecnica e l’utilizzo che di questa hanno fatto vari artisti. Questo consente di delineare alcuni processi cognitivi riflessivi connessi alla pratica del collage che lo rendono strumento efficace in contesti formativi, soprattutto quando rivolti a insegnanti ed educatori. In chiusura, pertanto, si andranno presentando alcuni esempi di esperienze formative che hanno visto il ricorso al collage come strategia riflessiva.

  14. Primo Levi and Ivan Denisovič: The Literary Act between Representation and Expressive Capacity

    Directory of Open Access Journals (Sweden)

    Pietro Tosco

    2011-11-01

    Full Text Available Se questo è un uomo di Primo Levi e Una giornata di Ivan Denisovič di Aleksandr Solženicyn sono due “atti letterari” che hanno contribuito in modo significativo alla conoscenza storica del XX secolo: il primo nell’Occidente dei campi di concentramento nazisti, il secondo nell’Oriente del Gulag. Perché sono così famosi? C’è qualcosa che li accomuna? Questo saggio si propone di analizzare la forza della letteratura come luogo di conoscenza e autocoscienza. Se le opere di Levi e Solženicyn hanno un grande valore come testimonianze, in esse la forza della testimonianza è data dal “gesto letterario” che le ha create, un gesto che produce una conoscenza sintetica in cui gli universali esistono solo nel particolare.

  16. he ‘Fabulous Dragon’s Teeth’: Censorship and Self-Censorship in the Italian Translation of Paradise Lost

    Directory of Open Access Journals (Sweden)

    Daniele Borgogni

    2015-05-01

    Full Text Available Il presente contributo discute le molteplici prassi che, sotto forma di espurgazioni religiose, adattamenti neoclassici, mutilazioni stilistiche, hanno caratterizzato le traduzioni italiane del Paradise Lost di John Milton. La difficoltà nell’accettare  l’eterodossia stilistica e religiosa del grande poeta inglese ha tradizionalmente favorito una serie di versioni infarcite di “migliorie” che hanno  offuscato o travisato il testo miltoniano anche in tempi recenti. Il contributo discute in dettaglio l’atteggiamento idiosincratico nei confronti di Milton e del suo capolavoro, nonché i pregiudizi, le pratiche di autocensura e le strategie più o meno vincenti adottate dai traduttori. La traduzione viene dunque utilizzata  come indice culturale ampio, strumento di indagine privilegiato in quanto fisiologicamente legata a pratiche di censura, ri-creazione e ri-mediazione dell’oggetto letterario nel suo passaggio tra sistemi culturali diversi.

  17. Camões e Tasso: l’Oriente nel poema eroico

    Directory of Open Access Journals (Sweden)

    Anna Cerbo

    2011-11-01

    Full Text Available Questo contributo si è proposto lo studio della presenza dell’Oriente nel poema epico europeo del Cinquecento. La struttura e l’elaborazione del discorso si sono basate soprattutto sul confronto di due opere: la Gerusalemme liberata di T. Tasso e I Lusiadi di L. de Camões . L’analisi testuale e la metodologia comparatistica hanno portato alla conoscenza storico-ideologica, culturale-letteraria e linguistica dei due poemi, e hanno consentito di rilevare le affinità e le differenze nel rapporto con l’’altro’ e nella rappresentazione dell’‘altro’ da parte dei due Poeti, entrambi attenti allo sguardo incrociato dell’Occidente e dell’Oriente. Tra i risultati conseguiti aggiungiamo che  è stato possibile individuare una comune retorica dell’‘alterità’ nella letteratura europea del Rinascimento.

    1997-01-01

    Abbiamo spesso un'idea confusa di quelle che sono state le vite degli uomini che hanno consacrato all'impresa scientifica le loro migliori energie. Eppure, non solo nell'arte e nella filosofia, ma anche nella scienza "lo stile è l'uomo" e la psicologia del singolo scienziato può rivelarsi il miglior aiuto per capire la logica della scoperta scientifica. Questa è una "storia della scienza raccontata agli amici davanti al caminetto", come l'autore stesso definisce la propria opera. Che non è soltanto una ricostruzione puntuale delle svolte principali che hanno portato alla scienza contemporanea, ma un racconto delle vicende personali di tutti quegli scienziati che sono stati divorati dalla passione del conoscere.

Sono stati selezionati dieci lavori, pubblicati tra il 2006 e il 2013, che hanno trattato la figura dell’e-tutor nei diversi contesti formativi italiani (università, scuola, Pubblica Amministrazione, e che hanno fornito evidenze empiriche su ruoli, funzioni e competenze, nonché sulle modalità di selezione, formazione e valutazione. Le analisi condotte sono state sia di tipo quantitativo (mediante questionari e successive elaborazioni statistiche sia qualitative (analisi del contenuto dei messaggi su forum di discussione. Risultano ancora pochi i contributi scientifici sull’e-tutor, a causa, come sottolineato da diversi autori, della difficoltà di realizzazione di ricerche empiriche o sperimentali. Vengono discussi limiti e alcuni spunti per le future ricerche.

Mancavano infatti brani audio prodotti dalla comunità locale. In realtà, però, la competenza tecnica necessaria a trasmettere i contenuti nel parco e in rete è minima (upload da CMS wordpress e anche le tecnologie per registrare e arricchire l’audio con effetti sonori sono alla portata di tutti, se opportunamente guidati da esperti. Da queste osservazioni è nato il progetto WiFiabe. Nel corso dell’anno scolastico 2010/2011 20 bambini tra 6 e 13 anni, coordinati da un’educatrice durante l’attività di doposcuola del Comune, hanno lavorato in gruppi e creato storie di fantasia. In seguito, alcuni studenti dell’Università di Siena, con l’aiuto di un musicista per la parte degli effetti sonori, hanno assistito i ragazzi nel diventare autori digitali e apprendere in prima persona come trasformare le loro storie in contenuti audio. In questo modo i partecipanti hanno interagito con il web non in quanto fruitori ma come autori, e messo in moto un processo per rendere WiRoni uno strumento per dare voce alle varie anime della comunità.

    Full Text Available ‘Il pareggio elettorale è la vita’: Boris e la satira dei mass media italiani e dell’industria culturale odierni  Nel 2007 il network satellitare Fox Italia ha cominciato la produzione di Boris, una serie comica del genere mockumentary messa in onda sui canali Sky Italia dal 2007 al 2010. La trama di Boris narra le peripezie di una troupe televisiva alle prese con la produzione di una soap-opera per la RAI. In Italia la serie è presto diventata un prodotto ‘cult’. Nella serie Boris i pigri e opportunisti membri della troupe televisiva fittizia sono rappresentati come succubi delle ripercussioni che gli sviluppi politici nel Paese hanno sul servile network per il quale lavorano. Gli attori nella soap-opera fittizia vengono rimpiazzati e la trama stessa della soap-opera viene riscritta a seconda delle nuove coalizioni che vengono formate in Parlamento e i membri della troupe sono costantemente alla ricerca di raccomandazioni e protezione politica. Per quanto satirizza lo stato del Paese, Boris mette anche in discussione il fatto stesso che l’industria culturale Italiana corrente possa produrre un discorso significativo. Con riferimento alla teorizzazione della ‘parodia’ da parte di Linda Hutcheon, questo articolo discute la rappresentazione che Boris ha tratteggiato dell’industria culturale, analizza il rapporto esistente tra la serie e tradizioni comiche Italiane che l’hanno preceduta (la ‘commedia all’italiana’ e il modo in cui l’ironia implementata dalla serie ricalca e/o diverge da quella tipica delle serie mockumentary estere che l’hanno ispirata (Arrested Development e The Larry Sanders Show.

    Experimental studies have revealed in drinking water the presence of mutagenic/carcinogenic compounds, such as pesticides, organic solvents, heavy metals and disinfection by-products and epidemiological studies have found cancer risk for populations exposed to these contaminants. Moreover, researches have shown reproductive and developmental hazards for people who consume drinking water containing endocrine disrupting chemicals. The aim of this review is to describe and evaluate the health hazards arisen from the human exposure to these drinking water pollutants potentially able to damage DNA and produce adverse reproductive effects. [Italian] Il monitoraggio delle sostanze genotossiche nelle acque potabili e' ormai una tecnica matura, applicata in numerosi laboratori in tutto il mondo che analizzano di routine le acque potabili. Gli stessi Standard Methods for Examination of Water and Wastewater statunitensi nel 1995 hanno introdotto per la prima volta l'indicazione del test di Ames come test di riferimento per condurre indagini di mutagenesi nelle acque. Negli ultimi anni ricerche sperimentali ed epidemiologiche hanno messo in luce un nuovo problema legato all'inquinamento idrico: la presenza di composti che producono effetti dannosi sulla salute riproduttiva umana. Grazie anche all'incremento degli studi sperimentali di tossicologia della riproduzione, un numero crescente di composti sono stati identificati come possibili fattori di rischio per la fertilita' e lo sviluppo. Inoltre alcune indagini epidemiologiche hanno rilevato possibili effetti dannosi sulla salute riproduttiva in gruppi di donne esposte a contaminanti idrici. Metodiche biologiche sempre piu' sofisticate sono in fase di sperimentazione e si spera che in futuro possano essere applicate anche per il monitoraggio degli inquinanti idrici tossici per la riproduzione umana.

    Obiettivi: l’associazione fra stato socio-economico (SES ed attività fisica è poco indagata. Obiettivo del presente studio è quello di valutare la relazione tra attività fisica extra-scolastica di adolescenti scolarizzati e lo SES della famiglia di provenienza.

    Metodi: l’indagine ha previsto la somministrazione nel corso dell’anno scolastico 2002-2003 di un apposito questionario anonimo autocompilato, già validato in uno studio pilota, ad un campione di studenti delle scuole medie inferiori del Lazio (province di Roma, Frosinone e Latina.

    Risultati: hanno partecipato allo studio 1486 studenti di cui 756 maschi (50.9% e 730 femmine (49.1%. L’età dei partecipanti varia fra gli 11 ed i 15 anni (età mediana 12 anni. Il 72.7% degli studenti dichiara di svolgere attività fisica al di fuori della scuola. Il livello di istruzione dei genitori e la loro attività lavorativa sembrano avere un peso notevole sui determinanti dell’attività fisica negli studenti. Infatti, svolgono prevalentemente attività fisica extra-scolastica i figli di genitori manager/libero professionisti (OR = 3.29 e con un elevato livello educativo (OR = 10.38 per i figli di genitori laureati.

    Conclusioni: i risultati confermano quanto la situazione socio-economica delle famiglie sia in netta relazione con l’attività fisico-sportiva dei giovani. Tali risultati potranno essere utili per gli operatori scolastici e gli amministratori nell’ispirare e realizzare azioni volte a diminuire il divario esistente fra i giovani che hanno le possibilità economiche e svolgono attività sportiva extra-scolastica e quelli che, invece, appartenendo a famiglie svantaggiate, hanno minore accesso a tali attività.

  12. La città sotterranea e il suo ruolo nella mobilità urbana

    Directory of Open Access Journals (Sweden)

    Giuseppe Mazzeo

    2008-12-01

    Full Text Available La città sotterranea è un elemento fondamentale nella struttura urbana. Soprattutto nelle grandi città essa assume connotazioni rilevanti nella pianificazione urbana in considerazione del fatto che rappresenta una risorsa e il suo impiego può incidere significativamente sull’efficienza del sistema urbano. Alcune città, a causa soprattutto della rigidità del clima, hanno progettato città sotterranee di grande complessità funzionale; esempi significativi sono Montreal, Toronto e altre città del Nord America. In Europa occidentale le realizzazioni associabili al concetto di città sotterranea sono più limitate e sono relative soprattutto alla realizzazione di infrastrutture per la mobilità urbana, come le reti metropolitane, i passanti ferroviari, i tunnel stradali e i parcheggi sotterranei. La funzione primaria di questi spazi è la riduzione e lo spostamento dalla superficie di quote di traffico e la trasformazione di ampie parti della città in aree verdi o in aree a maggiore qualità ambientale. In ogni modo è possibile sostenere che l’uso degli spazi sotterranei è ormai entrato a far parte della vita delle città moderne. L’articolo analizza alcuni dei fattori principali nella costruzione di questi spazi urbani; i costi e i benefici dell’uso di spazi sotterranei sono messi in relazione con gli aspetti psicologici e con la costruzione di modelli per la previsione dei percorsi degli utenti. La seconda parte dell’articolo mostra alcuni casi studio evidenziando le diverse necessità che hanno spinto e hanno guidato verso la scelta degli spazi sotterranei; una analisi più dettagliata è svolta sul caso di Montreal, che può essere considerato archetipo della citta sotterranea.

    2008-03-01

    Full Text Available Con Amati cani ci discostiamo per una volta dalle pubblicazioni a carattere scientifico, per dare il giusto risalto ad un’interessante raccolta di narrativa che esplora il rapporto tra l'uomo e il suo miglior amico. José Jorge Latria, noto soprattutto per essere un esponente di spicco della canzone politica portoghese e per le sue opere poetiche, teatrali e di letteratura per ragazzi, nello scrivere questo libro compie un vero e proprio atto d’amore verso i cani, con il preciso intento di costringere i lettori ad eliminare dal proprio vocabolario il gratuito modo di dire ‘mondo cane’. L’Autore delinea brevi ritratti di cani che, da Argo in poi, hanno accompagnato da amici veri i loro celebri padroni nella buona e nella cattiva sorte: racconta cioè la storia di quei cani che non sono sprofondati nella voragine dell’oblio perchè i loro padroni hanno raggiunto la celebrità nel mondo della letteratura, della politica, del cinema, delle scienze o della musica. Con a fianco un amico fedele come un cane, la vita ha avuto un sapore diverso per Ernest Hemingway, Isaac Newton, Sigmund Freud, Buster Keaton, Marilyn Monroe, Pablo Picasso, John Steinbeck, Lord Byron, Tim Burton e altri ancora, tutti personaggi che sono presenti in questo libro grazie ai cani che hanno condiviso con loro la vita e le memorie. La lettura di Amati cani dà piacere poichè in ognuno di questi racconti batte, affettuoso e delicato, il cuore di un cane; ma dà anche un pò da pensare in quanto celebra in maniera molto tenera l’amore, la fedeltà e la solidarietà tra l’uomo e il suo speciale amico a quattro zampe.

    Gli studi degli anni Ottanta sulla leadership femminile nera, raramente di carattere storico, ne hanno evidenziato soprattutto i connotati simbolici, in cui spesso i confini tra vite personali e ruoli organizzativi sono assai sfumati. L'immagine di una leadership debole da essi proposta è stata tuttavia smentita dalla storiografia più recente, che peraltro appare ancora ad uno stadio embrionale. Tutto ciò spiega almeno in gran parte perché sia tanto a lungo stata trascurata la figura di Mary ...

    Full Text Available Questo saggio si propone di dimostrare che il femminismo non si riduce all’umanesimo, essendosi spinto fino alla critica radicale dei suoi concetti-chiave. Si indaga quindi il modo in cui le analisi femministe e postcoloniali, grazie all’impulso del poststrutturalismo, hanno messo sotto esame il modello dell’“Uomo di ragione” ed elaborato visioni alternative dell’umanità, centrate su zoe come principio guida, capaci di andare oltre il genere, senza dimenticare le variabili di sesso, razza e classe. In conclusione si spiega come tali teorie rappresentino i presupposti della filosofia femminista postumana, riassumendo in quattro tesi le sue peculiarità principali.

  6. La fisica del Novecento per un bilancio critico

    CERN Document Server

    Selleri, Franco

    1999-01-01

    Ma chi ha detto che la fine della fisica è vicina? Che tutto quello che c'era da scoprire è già stato scoperto? E che le generazioni future potranno solo precisare e raffinare, e mai negare o arricchire le attuali teorie? Questo libro si contrappone a pensatori come Heisenberg, Feyman e Hawking che hanno predetto la morte della fisica. L'autore sostiene che grandi progressi sono possibili, ma che il prezzo da pagare per realizzarli è una modifica radicale delle basi della fisica moderna, in particolare abbandonando l'indeterminismo, la non località (paradosso di Einstein, Podolsky e Rosen) e lo stesso principio di relatività.

Gli strumenti di pianificazione utilizzati nel passato si sono rivelati inefficaci ed hanno prodotto una città in larga parte illegale che oggi appare ingovernabile. Tuttavia anche i nuovi strumenti del piano strategico e del progetto urbano sembrano mostrare i propri limiti. Una maggiore integrazione tra politiche urbane ancora troppo settoriali può contribuire alla definizione di approcci realmente innovativi.

    L'anomalia regionale è dovuta all'effetto delle strutture profonde

In alcuni casi è inevitabile, altre volte no, ma sempre più spesso ci sentiamo costretti a cercare di fare più cose simultaneamente. Possiamo veramente dividere la nostra attenzione conscia tra due compiti impegnativi, come leggere e scrivere? In questo articolo si riportano risultati sperimentali che hanno dimostrato che il risparmio di tempo può essere illusorio e che la performance ha un decadimento rispetto alle situazioni in cui è possibile svolgere i compiti in sequenza.

In molti casi, beninteso, non è che il potere in altre forme, che interferisce con se stesso: pensiamo ai bandi affissi agli angoli delle città, o le lettere d’indulgenza papali -spesso impreziosite da miniature al punto da poterle considerare antenate dal manifesto- che nel corso del medioevo venivano affisse sulle porte delle chiese.

    RIASSUNTO. Il fenomeno delle persone senza fissa dimora sta assumendo in questi anni una rilevanza sociale devastante, con una prevalenza stimata in USA e in Europa compresa tra il 5,6% e il 13,9%. Queste persone hanno una scarsa qualità di vita, una limitata o assente vita sociale, sono spesso disoccupate o lavorano solo saltuariamente. Sono a rischio di problemi con la legge, sono spesso affette da dipendenza da droghe, da patologie psichiatriche e internistiche. L'alcol spesso non rappresenta la causa della loro condizione sociale, ma solo la conseguenza, contribuendo in questo modo al loro degrado bio-psico-sociale. Nel 2009 lo US Department of Housing and Urban Development's Homelessness Assistance Programs e nel 2010 la European Consensus Conference on Homelessness hanno segnato un grande passo avanti nella riabilitazione sociale di queste persone, utilizzando il concetto del "case management". In particolare lo Standard Case Management si è dimostrato in grado di migliorare la stabilità abitativa, di ridurre l'uso di droghe e di rimuovere le barriere lavorative. L'Assertive Community Treatment si è dimostrato, invece, in grado di migliorare la stabilità abitativa e ha un rapporto costo/beneficio migliore per i pazienti affetti da doppia diagnosi.

    Full Text Available Da oltre un ventennio, il tema della guerra da corsa e quello del commercio dei captivi nel Mediterraneo di età moderna, ad esso strettamente connesso, sono oggetto di rinnovato interesse da parte della storiografia internazionale. Soprattutto in Italia, Spagna e Francia (ma anche altrove, ricerche sistematiche hanno permesso di ricostruire diversi aspetti della schiavitù nel Mediterraneo di età moderna: modalità della cattura, condizioni di vita dei prigionieri, riscatti, conversioni. Non solo storici, ma anche antropologi, economisti, storici delle religioni e del diritto hanno dato il loro contributo alla ricerca, tradottosi in raccolte di saggi o in volumi monografici; tale abbondante produzione ha innanzitutto mostrato chiaramente come la guerra da corsa e il commercio dei captivi abbiano rappresentato a lungo un elemento cruciale della storia dei paesi che si affacciano sul Mediterraneo, dal medioevo all’età moderna, giungendo fino ai primi decenni del secolo XIX. Nelle prossime pagine proveremo a ricostruire, a grandi linee, l’evoluzione del dibattito storiografico sull’argomento, in modo da far emergere le questioni ancora aperte e di individuare nuovi possibili percorsi di indagine, che sfruttino in particolare le serie documentarie ancora scarsamente utilizzate o meritevoli di ulteriori ricerche.

    Full Text Available L’articolo stabilisce un confronto fra la cortigiania, ovvero la filosofia del comportamento raffinato dell’uomo cortese proposta dal testo Il cortigiano di Baldassare Castiglione, e la cortesana filosofia presente in tutta l’opera di Gracián. Questi due autori, che hanno vissuto in paesi e luoghi differenti, hanno dei principi filosofici, antropologici e religiosi molto diversi. Si distinguono dunque sia dal punto di vista letterario sia per il loro approccio teorico. Il primo offre un nuovo modello sociale di comportamento legato alla struttura particolare della corte all’inizio dell’epoca moderna; il secondo si propone esplicitamente di creare un «prodigio», un uomo «artificiale» che sappia far fronte alla realtà ingannevole, che sappia sopravvivere in un mondo ostile. Egli annuncia in un certo senso il passaggio dalla tradizionale società d’ordini, in cui ognuno ha sin dalla nascita il suo posto assicurato nella società, al mondo dell’«individualità astratta»

    Full Text Available I film hanno rappresentato l’evoluzione del paesaggio italiano per gran parte del novecento. Negli ultimi due decenni i film italiani hanno però smesso di esplorare le trasformazioni del territorio. La debolezza dell’industria cinematografica spiega in parte l’assenza del contemporaneo dagli schermi. Inoltre il diffuso ricorso al supporto economico degli enti pubblici, che spesso vedono i film come strumenti di promozione turistica, sembra influenzare le modalità di rappresentazione del paesaggio. Il contributo presenta una ricerca condotta sui film di maggior successo tra il 1990 e il 2014 alla ricerca dell’immagine del paesaggio italiano in essi prevalente e evidenzia alcune cause alla base di questa rappresentazione omogenea. Films have portrayed the evolution of the Italian urban landscape in the last 100 years. Nevertheless, contemporary movies partially ignore the recent transformations and represent instead a stereotyped image of Italian landscapes. The structure of the local movie industry could provide a first explanation of this phenomenon. Moreover, the financial support of productions provided by local government influences the choice of including or excluding elements of the landscape in the movies screen. The paper explores the new representations of landscape in Italian movies, in order to show which features of the changing contemporary Italian landscapes are visible and which are hidden.

In particolare, durante il progetto gli autori del libro hanno sviluppato un percorso didattico modulare sulla matematica del gioco d'azzardo che gli insegnanti di matematica delle scuole secondarie possono utilizzare sia per introdurre gli strumenti di base del calcolo delle probabilità sia per sensibilizzare sui rischi legati al gioco d'azzardo. Il libro descrive i pilastri metodologici e concettuali che hanno guidato la concezione e dato forma al percorso didattico, ovvero la centralità del ruolo dell'insegnante, l'uso dei simulatori di gioco, l'importanza delle attività di gruppo e il ruolo delle emozioni nell'affrontare e comprendere nuovi concetti matematici. Nel libro, ciascuno di questi pilastri è trattato sia mediante ...

  19. La crisi energetica nel mondo e in Italia da Enrico Fermi ed Edoardo Amaldi a oggi

    Enrico Fermi e il suo allievo Edoardo Amaldi, grandi padri della Scuola di fisica nucleare italiana, hanno promosso l'impiego pacifico dell'energia nucleare: Fermi con il primo reattore a Chicago nel 1942, Arnaldi con i suoi contributi a tutti gli usi pacifici, dalla medicina alla produzione di energia. L'Italia, però, ha fatto eccessivo ricorso al petrolio, di cui non è produttrice. La ricerca è rimasta molto indietro rispetto a quella degli altri paesi e la politica sta dedicando pochissimi sforzi a questa gravissima situazione. Ragioni economiche, nonché ambientali, esigono ora una revisione e una ricontestualizzazione del problema. Durante un importante Convegno, tenutosi a Roma il 15 e 16 maggio 2007, alcuni tra i più noti ed esperti fisici italiani e stranieri hanno discusso proprio di questo problema. L'intento del volume, che raccoglie gli interventi del Convegno romano, è quello di fornire dati e informazioni che mettano il lettore in condizione di farsi un'idea propria, libera da pregiudizi, s...

  20. Fisica e filosofia come la scienza contemporanea ha modificato il pensiero dell'uomo

    Heisenberg, Werner

    2003-01-01

    Nel corso del Novecento le scoperte della fisica – dalla meccanica quantistica alla teoria della relatività, dalle ricerche sul cosmo all’energia nucleare – hanno travolto le precedenti nozioni di spazio e tempo e rivoluzionato la percezione che l’uomo aveva di sé, investendolo inoltre della responsabilità di una possibile autodistruzione. Figura geniale e controversa, Werner Heisenberg è stato un protagonista assoluto dell’epopea scientifica del secolo scorso, insieme a Bohr e Fermi, Einstein e Planck. Fisica e filosofia esplora la complessità di quello snodo offrendo risposte chiare a domande che non hanno mai perso la loro centralità. Cosa affermano le teorie della fisica contemporanea? In che modo investono la concezione che l’uomo ha di sé? Quali sono i limiti etici delle loro applicazioni tecnologiche? E quale sarà l’influenza politica della scienza su scala planetaria? Affrontando quesiti di portata universale, Heisenberg si dimostra consapevole della necessità di ristabilire la ...

    Full Text Available La presenza di un’importante stratificazione archeologica nella città di Milano è fatto noto da molto tempo e i cantieri che si sono succeduti, segnando la trasformazione urbanistica della città a partire dal secolo scorso, ne hanno dato ampia testimonianza, anche se spesso non accompagnata da adeguata valorizzazione. Le ricerche e gli studi hanno chiaramente individuato i capisaldi urbanistici di Mediolanum, sviluppatasi in vero e proprio centro urbano da un insediamento celtico, a partire dall’epoca augustea, quando furono eretti quegli edifici monumentali (il foro con i suoi annessi, il teatro, le mura, l’anfiteatro necessari allo svolgimento della vita politica, religiosa, economica e sociale dell’epoca. Il panorama monumentale della città si arricchì ulteriormente alla fine del III secolo d.C. quando Mediolanum fu scelta da Massimiano quale sede imperiale, ruolo svolto fino agli inizi del V secolo d.C.: l’ampliamento delle mura, la costruzione del complesso palazzo imperiale – circo e l’edificazione di un imponente complesso termale (Fig. 2 – resero Milano uno delle più importanti città dell’impero romano d’Occidente.

    Full Text Available Questo contributo ruota intorno ai risultati di una ricerca collettiva che riguarda i rapporti fra alcuni oggetti della casa e le memorie di chi li raccoglie. Il tema di sfondo della ricerca è molto ampio. Nelle case ci sono mobili e soprammobili, fotografie e manifesti, quadri, e infiniti altri oggetti. Possiamo dire che la casa intera è un deposito di “mnemoteche”, di teche della memoria, che è la stessa disposizione dello spazio domestico a fungere da dispositivo mnestico. Rispetto a tutto ciò, abbiamo scelto quelli che hanno a che fare con il mondo dei media. Ci siamo occupati cioè di come vengono raccolti, selezionati, conservati, usati e scartati oggetti come libri, dischi, videocassette, CD e DVD, e anche file sui computer, telefonini e lettori portatili (audio-video. Si tratta di un insieme di oggetti la cui analisi consente di comprendere sia diversi aspetti dei rapporti che le persone intrattengono con le proprie memorie, sia alcuni dei modi in cui spazi privati e pubblici si interconnettono. Poiché questi prodotti hanno a che fare con le industrie mediali, abbiamo chiamato l’insieme di questi oggetti mediateche domestiche.

    Full Text Available Obiettivo di questo lavoro è quello di fornire le principali linee di orientamento teorico dell’approccio psicodinamico relative alla funzione del sogno. In tal senso ci si avvarrà della metapsicologia Freudiana, ma anche dei prestigiosi contributi sul carattere del sogno portati da Wilma Bucci. In particolare, si proporrà un parallelismo tra la metapsicologia e la teoria del Codice Multiplo. La teoria energetica di derivazione psicoanalitica mette in risalto alcuni punti cardine sul ruolo del sogno: 1 il sogno deriva dall’energia di un desiderio inconscio; 2 i sogni hanno la funzione di preservare il sonno; 3 la nozione di un censore che si attiva per distorcere e mascherare i contenuti latenti; 4 i contenuti manifesti hanno la funzione di nascondere il reale significato del sogno. Secondo la teoria del codice multiplo, il sogno ha un valore là dove fornisce l’accesso al significato emotivo che è stato dissociato, ma la funzione dell’elaborazione dell’informazione emotiva nel sogno è sovrapponibile a quella dell’elaborazione dell’informazione emotiva durante la veglia, in particolare per quanto riguarda il sonno REM.

    2007-01-01

    La teoria delle stringhe, "eterna promessa" della fisica teorica, sembra oggi giunta alla resa dei conti, e molti studiosi si stanno da tempo interrogando sulla sua reale validità. Un certo malcontento già serpeggiava nei corridoi delle università e in alcuni scritti quasi clandestini ma ora giunge dagli Stati Uniti la voce di Peter Woit, ferma e decisa nel lanciare un messaggio chiaro: questa presunta "teoria del tutto" che pretendeva di unificare le leggi della fisica, si è rivelata alla fine una "teoria del niente", incapace di dimostrare anche uno solo dei suoi enunciati. Dopo una dettagliata panoramica sugli sviluppi della fisica che hanno portato, nella metà degli anni Settanta, alla nascita e al successo del Modello standard, Woit giunge quindi al cuore del suo libro. L'accusa è pesante: non solo i teorici delle stringhe non fanno scienza, ma hanno goduto di un predominio eccessivo per vent'anni, monopolizzando il reperimento dei fondi economici pubblici e privati e impedendo di fatto un sano pro...

  7. Le narrazioni come metodo di indagine sociologica

    Full Text Available L'incontro trentino ha dimostrato l'interesse crescente dei giovani sociologi per lo sviluppo dei metodi narrativi e la capacità che questi hanno di essere efficaci nell'analisi di svariati temi, dai racconti di malattia alle narrazioni identitarie, dallo studio di lavoro e organizzazioni a quello delle migrazioni, di genere e memoria. Tuttavia, l'interesse della sociologia italiana va visto in un quadro di sviluppo più ampio a livello europeo e americano dove, a partire dagli anni '90, l'intervento di alcuni autori come Lyotard, Bruner e Macintyre, ha sancito quella che alcuni autori hanno definito svolta narrativa. La sociologia, infatti, tende sempre più a valorizzare la narrazione come processo di conoscenza peculiare che è attivato costantemente nella vita quotidiana; la "rivoluzione" risiede nel fatto che la narrazione diventa oggetto della sociologia e la disciplina stessa valorizza il suo uso sia come strumento di indagine scientifica, sia come modo di conoscere che come modo di comunicare, rivendicando la legittimità scientifica all'ascolto della parola diretta degli individui coinvolti all'interno delle ricerche di stampo sociologico.

    2015-11-01

    Full Text Available Il saggio considera l'esperienza politica degli intellettuali cinesi e americani in Chinese Opera (1998, romanzo breve dello scrittore americano di discendenza cinese Alex Kuo. Il suo protagonista, compiendo un viaggio dagli Stati Uniti alla Cina nei mesi immediatamente precedenti alle dimostrazioni di piazza Tiananmen, intraprende un cammino alla ricerca della sua storia familiare, e delle ragioni che hanno spinto il padre all'esilio. Intellettuale e musicista, a cavallo tra due realtà di attivismo politico che hanno esercitato il loro peso nel definire o nello smantellare, a seconda delle prospettive, proprio i concetti di appartenenza, il protagonista sceglie e fa proprio l'impegno sul piano transnazionale, ma a partire da una consolidata quanto rivendicata consapevolezza della propria individualità. La letteratura e l'arte sono il punto focale in grado di esprimere una tensione tra l'individuo e la collettività che ritorna con una declinazione diversa in entrambi i sistemi socio-politici. Il romanzo, dunque, propone un soggetto politicizzato ma non contenibile all'interno di alcuna coordinata discorsiva pre-scritta. A sua volta, il discorso politico nel testo letterario, costruito nel senso della double critique di Khatibi, intreccia la dimensione pubblica e privata dell'intellettuale con le significazioni etniche, nazionali e transnazionali.

    Full Text Available Questo saggio prende in considerazione i retaggi della educazione dell’apartheid e le nuove direttive entrate in vigore dal 1994, innanzitutto problematizzando il concetto di retaggio dell’apartheid e poi esaminandolo all’interno del più vasto contesto storico che vede l’emergere di un sistema di scolarizzazione di massa differenziato su base razziale, nelle particolari condizioni politiche ed economiche del Novecento. I principali retaggi che la nuova politica del periodo post-apartheid si proponeva di affrontare comprendevano: 1 i finanziamenti, l’organizzazione e le risorse diseguali riservati alle diverse razze; 2 la scarsa qualità dell’istruzione per la popolazione nera; 3 l’alto livello di disoccupazione giovanile; 4 i bassi livelli di partecipazione all’educazione degli adulti e all’istruzione tecnica e superiore. Il saggio mostra come le nuove iniziative per la riorganizzazione dell’istruzione, la politica sul personale docente, il curriculum, lo sviluppo delle compe- tenze e l’istruzione superiore siano state prese in condizioni economiche e politiche particolari e dimostra che non hanno modificato marcate diseguaglianze e non hanno segnato una discontinuità rispetto ai risultati dell’apprendimento. Contrariamente alle posizioni di chi nega l’apartheid, questa contraddizione è spiegata in rapporto alla forte presenza del passato nel presente, alla contraddizione fra intenti educativi e risultati, e al ruolo subordinato dell’istruzione in qualunque ordine sociale.

    Full Text Available Le tecnologie visuali, e il disegno in particolare, mirano spesso a documentare gli impatti di interventi futuri, essendo esse, per natura, dei mezzi di comunicazione equiparabili al linguaggio, e dunque preposti a descrivere e dimostrare ciò che sta accadendo. Il disegno è, da sempre, il linguaggio universalmente valido e conosciuto: questa sua peculiarità deve far riflettere sulle sue potenzialità. Se da un lato ha la valenza di strumento chiarificatore dall’altro può essere visto come supporto e mezzo preventivo a un miglioramento di interventi futuri, architettonici o ambientali. Come i pittori, da Cimabue a Giotto, da Mantegna a Leonardo, a Raffaello, hanno creato con le loro tele, elevando il livello artistico e culturale del tempo, o i grandi architetti, da Palladio a Bramante fino a Le Corbusier hanno costruito con i loro progetti, così il disegno, material prima di pittori, di architetti, o di chiunque si accinga a realizzare un’idea in fieri, deve assumersi la responsabilità e il compito di “essere un bel disegno”, per migliorare ciò che più riguarda l’uomo: l’ambiente in cui vive.

Nel periodo post-riproduttivo (luglio, i censimenti sono stati condotti lungo 20 percorsi supraforestali fissi, con l’obiettivo di stimare le variazioni nelle dimensioni, rapporto sessi, struttura e produttività della popolazione nell’area protetta. La densità media è risultata pari a 6,7 camosci km-2, il rapporto sessi circa 1:3 in favore delle femmine, mentre la produttività è stata pari a 0,6 juvenes per femmina adulta. La proporzione di animali indeterminati durante i conteggi è diminuita significativamente nel tempo, probabilmente in seguito al progressivo training degli operatori. Nel periodo di studio, le dimensioni della popolazione sono fluttuate significativamente. Sebbene le cause di tali variazioni siano ancora da approfondire, le successive epidemie di cheratocongiuntivite infettiva e Pestivirus che hanno colpito la popolazione hanno probabilmente svolto un ruolo determinante. Si raccomanda di sviluppare un piano di gestione dell’intero massiccio montuoso, che includa regolari monitoraggi sanitari e conteggi autunnali.

Per ovviare ai limiti del paradigma psicometrico, che si è focalizzato prevalentemente sui processi cognitivi trascurando il contesto sociale nel quale la persona è inserita, il presente studio si è proposto di esplorare il contenuto e il campo delle rappresentazioni sociali del rischio ?uranio impoverito?. Si è fatto ricorso alla tecnica delle associazioni libere, chiedendo ai partecipanti (N= 1158, età media 26.7 anni, DS = 11.04, 42% uomini, con diverso orientamento politico di esprimere fino a 3 parole pensando a ?uranio impoverito? e di valutarne la positività/negatività su scala a cinque punti da 1 (molto positiva a 5 (molto negativa.

Metodi: l’indagine, svolta nell’ottobre 2002, ha previsto la compilazione di un questionario, riguardante gli aspetti strutturali, impiantistici, organizzativi e gestionali, e l’effettuazione di un monitoraggio microbiologico ambientale nelle diverse aree del blocco operatorio. La carica microbica dell’aria è stata valutata utilizzando piastre di sedimentazione per la rilevazione dell’Indice Microbico Aria (IMA mentre per le superfici sono state impiegate membrane di nitrocellulosa. I campionamenti sono stati effettuati prima dell’inizio e durante l’attività chirurgica. Risultati: i dati ottenuti per mezzo del questionario hanno evidenziato condizioni generalmente buone, sia dal punto di vista strutturale che gestionale del comparto operatorio studiato. Per quanto riguarda il controllo microbiologico, nelle sale operatorie, in tutte le rilevazioni prima dell’attività si sono ottenuti valori di IMA uguali a 0; durante l’attività, si è registrato un valore massimo di IMA di 4 in quelle a flusso laminare e di 19 in quelle con flusso turbolento, al di sotto dei valori limite, rispettivamente di 5 e 25; i valori di contaminazione microbica delle superfici prima dell’attività hanno oscillato da un minimo di 0 ufc/cm2 a un massimo di 0,20 ufc/cm2; durante l’attività, solo in una rilevazione si è registrato un valore di 0,58 ufc/cm2, superiore al valore soglia stabilito. Anche negli altri ambienti del comparto operatorio la contaminazione microbica è risultata complessivamente al di sotto dei limiti di riferimento. Conclusioni: il questionario si è rivelato un valido strumento

    Full Text Available Abstract Over the last decades, dramatic changes in agricultural practices have led to important modifications of land-use, as well as landscape structure, and to a general biodiversity loss in agro-ecosystems. During 2008 we investigated the small mammal communities of Short Rotation Forestry (SRF stands in Northern Italy. We live-trapped small mammals, during summer and autumn, in different types of SRF stands and surrounding habitats and compared capture rates. We evaluated the influence on small mammals abundance of the distance between the stands and other habitats offering woody or bushy cover. Our results showed that SRF plantations are widely exploited by small mammals, especially in autumn and that capture rate is the highest in “double-row” stands. The distance from woods or other arboriculture stands was negatively correlated to small mammals abundance. We conclude that SRF plantations can be considered a suitable habitat for small mammals and may work as a “corridor habitat” between fragmented patches of suitable habitats.
    Riassunto Uso degli impianti a turno breve da parte dei micrommamiferi, in relazione alla loro struttura e isolamento Negli ultimi decenni profondi cambiamenti nelle pratiche agricole hanno causato modifiche nella tipologia di uso dei terreni, così come nella struttura del paesaggio, che hanno portato a una generale perdita di biodiversità negli agroecosistemi. Nel corso del 2008 abbiamo studiato le comunità di micromammiferi nelle piantagioni di pioppo per la produzione di biomassa (SRF nel Nord Italia. Con l’uso di live-traps abbiamo effettuato due sessioni di cattura, una estiva e una autunnale, nei diversi tipi di impianto delle SRF e negli ambienti circostanti, per comparare le frequenze di cattura. Abbiamo quindi analizzato l’influenza che la distanza tra i diversi ambienti con copertura arborea ha sull’abbondanza dei micromammiferi

Summary: Locating, cleaning and shaping the entire root canal system may represent a difficult challenge particularly in mandibular premolars, because of their complex canal systems.For this reason mandibular premolars are often considered the most difficult of all teeth on which to perform successful endodontic treatment. Vertucci stated that the second premolar has one root canal at the apex in 97.5% of the teeth studied and two canals in only 2.5%.1 The following case report describes the diagnosis and retreatment of a second premolar with two canal in two roots.Key learning points: (1 The major cause of failure in root canal therapy is the inability to localize and treat all of the canals of the root canal system. (2 Mandibular premolars have complex canal systems. (3 Mandibular premolars have a high risk of missed anatomy. (4 Preoperative radiograph interpretation is essential to evaluate and detect uncommon anatomies. (5 The operating microscope and CBCT interpretation are fundamental in confirming and preventing mistakes about the configuration of mandibular premolars. Riassunto: Obiettivi: Presentare un caso clinico di ritrattamento canalare di un secondo premolare mandibolare con due canali e due radici. Riassunto: Individuare, sagomare, detergere l’intero sistema radicolare presenta una sfida difficile in ambito endodontico e in particolar modo nei premolari mandibolari per il loro complesso sistema canalare. I premolari mandibolari sono spesso considerati i denti più difficili in cui effettuare una terapia endodontica.Vertucci riscontrò che i secondi premolari mandibolari hanno una radice e un canale nel 97.5% e due canali in solo il 2.5%.1Il case report seguente descrive la diagnosi e il ritrattamento di un secondo premolare con due canali in due radici.Punti chiave di apprendimento: 1.

    Full Text Available La teoria delle obbligazioni rappresenta un significativo esempio di come un insieme di tecniche logiche possa essere applicato, in maniera feconda, a contesti disputazionali in cui la dimensione dialogica e l’interazione tra soggetti coinvolti in un confronto dialettico hanno un ruolo di primo piano. L’attenzione che numerosi studiosi hanno manifestato nei confronti di questa parte della logica modernorum negli ultimi quarat’anni testimonia la profondità e la difficoltà dei problemi teorici che stanno alla base della teoria. Molte interpretazioni sono state avanzate circa le motivazioni che spingono i logici medievali a scrivere trattati in cui il portato delle loro dottrine logiche – come, ad esempio, la teoria delle consequentiae - viene declinato ed elaboratamente applicato al gioco dialettico tra due disputanti. La gamma di tali letture comprende differenti ipotesi: la teoria delle obbligazioni potrebbe fornire un nucleo di regole per l’impostazione di un metodo assiomatico rudimentale così come rappresentare un tentativo di elaborare esercizi volti a valutare le capacità logiche degli studenti o, ancora, un gioco teorico, svincolato dall’effettiva applicazione a contesti concreti, la cui finalità sarebbe il mantenimento della coerenza logica. E’ stata sostenuta da più interpreti la funzione pedagogica svolta dalla teoria, al di là del fatto che si tratti o meno di un metodo per la conduzione effettiva di dispute reali. Un’altra linea interpretativa collega la teoria delle obbligazioni al contesto della letteratura dei sophismata e degli insolubilia, dal cui repertorio, in effetti, sono spesso tratti molti degli esempi che si incontrano nella lettura dei trattati de obligationibus. In questo senso, la teoria offrirebbe regole e schemi di risposta che un interlocutore deve utilizzare per risolvere o rispondere a enunciati problematici o paradossali. Non si può escludere, inoltre, che nella teoria si realizzi un

La raccolta dei dati si è svolta in tre giornate: nella prima le partecipanti hanno scritto un testo collaborativo a partire da una storia per immagini; nella seconda i testi, corretti con un intervento di feedback implicito, sono stati riconsegnati e la coppia ha prima analizzato le segnalazioni ricevute e poi riscritto il testo; nella terza le apprendenti hanno prodotto testi individuali a partire dallo stesso stimolo visivo. Oltre a confrontare le diverse stesure del testo, si analizzano le interazioni avvenute tra le apprendenti durante il lavoro di coppia finalizzato a utilizzare il feedback per produrre il secondo testo collaborativo. I risultati mostrano da un lato che un elevato livello di coinvolgimento nell’elaborazione del feedback non ne garantisce un utilizzo efficace, dall’altro che hanno un peso non trascurabile anche fattori più “personali” come le convinzioni sulla lingua bersaglio e l’atteggiamento nei confronti del lavoro di coppia.  A case study on the development and use of written feedback in Italian L2 learners  Through a case study involving two female elementary/intermediate Italian L2 students, we examine some of the factors that may affect the use of written feedback by the learners. Data collection took place over three days: on the first day, the participants wrote a collaborative text from a picture story; on the second the texts, corrected using implicit feedback, were returned, and the students first analyzed the reports received and then rewrote the text; on the third day the learners produced individual texts from the same visual stimulus. In addition to comparing the various drafts of the text, we analyzed the interactions between the learners during pair work aimed

    Full Text Available Nel 2001 e 2002 in provincia di Gorizia (loc. Isola della Cona, Riserva Naturale Regionale Foce dell?Isonzo due giovani maschi di volpe sono stati marcati con radiocollari, al fine di raccogliere dati sulla loro dispersione. L?area di studio, di circa 20 km², presenta zone boscose, boscaglie golenali, prati umidi, canneti e barene, inserite, comunque, in un territorio soggetto ad agricoltura intensiva. Gli animali sono stati seguiti per 12 ore/notte nella prima fase e successivamente per 12 ore/settimana, suddivise in 3 turni tali da coprire l?intero arco della notte. La posizione è stata rilevata ogni 20 min. Il primo individuo (M1 è stato seguito dal 15.11.01 al 10.12.01 per 140 ore; il secondo (M2 dal 14.06.02 al 22.03.03 per 580 ore; la dispersione è iniziata il 17.11.01 per M1 e il 10.11.02 per M2. Entrambi hanno attraversato il fiume Isonzo, in un tratto ampio 145 m, in direzione Sud/Est, raggiungendo una zona agricola. In seguito non hanno mostrato la tendenza a tornare indietro, probabilmente a causa della presenza di un maschio territoriale. Durante il giorno non si sono verificati spostamenti apprezzabili. La massima area coperta per notte (metodo del Minimo Poligono Convesso è stata di 10,7 km² per M1 (settima notte e di 5,1 km² per M2 (diciassettesima notte. I punti più distanti raggiunti in linea d?aria rispetto a quello di attraversamento del fiume sono stati di 9,2 km per M1 e di 9,9 km per M2. La direzione e alcune delle traiettorie percorse sono risultate sovrapponibili per i due individui. Le convergenze di eventi che emergono dai risultati, raccolti a distanza di un anno, suggeriscono una certa obbligatorietà nei percorsi che potrebbe essere dovuta sia alla struttura territoriale che alla densità della popolazione di volpi (stimata tramite conteggio delle tane attive in 10-12 individui in periodo primaverile e in 27-30 individui in periodo autunnale. Si ipotizza una certa stabilità dei territori degli individui
