    The author described the direction to be taken in the coal mining industry .placed under the bad conditions by the energ y revolution.
    In the first chapter, he outlined the Temporary Law concerning Coal Mining Industy Rationalization Measures enforced in 1955. He pointed out too great difference between the initial aim and plan and the practical operation to bring out the available rationalization .
    In the second chapter, he outlined the revised rationalization plan reported by the Coal Mining Industry Council about the year-end of 1959 and the beginning of 1960. He described that scrapping of the olden equipment to concentrate the coal production on the higher effective coal mine, rationalization of circulating process, and modernization of techniques should be performed, and that in 1963 the output of coal shall amount to 55, 000, 000 ton per year, i. e., 26t/man/day, of which cost shall cut down 1, 200yen/t compared with that of 1958. Furthermore, he explained the Revised Coal Mining Rationalization Law available as from September, 1960.
    In the third chapter, from the viewpoint of the modern change of energy situations, he pointed out some parts desirable to revise the said plan, and gave his opinion upon the consequent important problems.

    The author made a tour of Inspection on the coal chemical industries in Eur opeas a member of“Japan Coal Chemical Industry Specialists Team to Europe”this spring. In this paper, he reports the present status of coal tar industry in Europe from various points of view according to this inspection.Namely, he describes in outline the future of coal mining industry, the recent trends on the coal carbonization, the tar industry as an enterprise, the condition of tar products, the recent technology of tar industry and the co-operative system among tar industry in West Germany, England, France and Italy, and he points out the some characteristics of the tar industries of these foreignc ountries as compared with Japanese tar industry.

    The author went to Moscow to lecture on “Tsutsumi Vacuum Cracking Process”at the Department of State Committee for Chemistry and Chemical Industry in U.S.S.R., andinspected on the Chemical industries of the country in last summer.
    In the paper, he describes in outline the petrochemical industries as synthetic fibers, gums and resins, the condition of lives of laboures and scientists, and he emphasizes the necessity of the co-operative system for studies.

    We investigated in this report the ability of Cu system catalyser.
    As the results, we found the facts as follows;In the investigation about Cu-Cr and Cu-Znsystem catalyser, in the former, liquid formation and contained volume of isobutanol in liquid of formation are very low and the life is very short, but in the latter, they are fairly good, however its life is short.
    By addition of Al on Cu-Zn systsm catalyser, its life become long and formation of water is fewer.

  • Studies on the Oxidative Degradation of Coal (IV)
    The Molecular Weight of Humic Acids

    The values of molecular weight of humic acids obtained by the cryoscopic method with organic solvents were discussed in order to re-examine their true meanings.The molecular weight of several compounds, containing carboxyl and/or hydroxyl groups and their derivatives, as the model of humic acid, were measured cryoscopically in organic solvents (p-nitrophenol, acetoamide etc).On the other hand, the appearent molecular weight of humic acids, their derivatives and solvent extracts of bituminous coal were measured fin the same way.From the above experiments, it was conclude that the values obtained as the molecular weight of humic acids was indipendent of the real value.That is, the value (300) obtained as the molecular weigth of humic acids in p-nitrophenol has been considered to be too small than expected from the other behaviours of humic acid, and it seems likely, as R.S.Smith et al suggested, that this small value is obtained as the, result of cleaving of humic acids in this solvent.The value (about 500-600) obtained in acetoamide was considered to be a value which was related to the equivalent weight of active functional groups in this solvent.
    Secondly, the molecular weight of humic acids were estimated from the degree of freezing point lowering of aqueous solution of potassium salt of humic acids and the van't Hoff factor calculated from the degree of dissociation of these salts. In the above treatment there are some points remained undisolved, however, it seems to give an approximate value of true molecular weight of humic acids. According to these experiments and considerations, it is concluded that the real value of molecular weights of humic acids, regenerated from bituminous coal or extracted from lignite, would be an order of several thousands, and the former has somewhat larger value than the latter.

    In order to obtain the foundamental data for ammonia synthesis gas directly from mine gas, i.e., methaneair mixure by partial oxidation and conversion, the author made experiments.
    As for the method of experiments and analysis of the results, he treated the data aim to obtain the foundamental data for development to utilize the pilot plant, which had been built for treating waste gas by-producted in the hydrogenation of coal.
    So, in the analysis of the reaction rate, the interaction was not considered stricktly.The author did not make any relation to the theroretical development of reaction conditions, which were difficult to reduce into theoretical reaction rate because of the experimental conditions and apparatus, but he could get some usuable results for aforesaid purpose.
