    The author inspected mainly the coal tar industry for four months from Aug. to Nov.1951, and 62 works which are related to coal tar distillation, coke oven and its by-product, wood preservation, fire brick as well as special grease were inspected. As for coke over, the types. used at present day and their capacity and proceeding of technique were reported. As for treatment of by-product, modern installation and proceeding of technique related to decanter, saturator, dryer, recovery of benzene, coal tar distillation, coal tar pitch, etc. were summarily described.

  • On the Combustion Test of Flame Counter Flow Type Stoker

    The author describes the results of the combustion test with the flame counter flow type stoker for low grade coal which has been consturched by the Nagasaki Dockyard of the West Japan Heavy Industry Co.
    The stoker has an inclined long arch which is almost parallet to step grate, and as the derivery of exhaust gas is being situated near the inlet of coal, the suface of coal on grate can be always heated with flame. Some results obtained with this stoker are as follows: When 4, 000 kcal/kg Joban coal was used, the grate was damaged by over heating, but the coal having a calorific value of 3, 700kcal/kg showed the good results.Nevertheless, the low gradw coal of 2, 000kcal/kg could be burned almost perfectly, being CO2 in flue gas 12% and boiler efficiency 63%.

    The authors had reported the manufacturing methods, of the ion exchangers by the sulfuric acid treatment of the coaly matters and their some behaviours in the previous reports.In these reports, the results of the experiments in which they were used as the catalysers of esterification of higher fatty acids, and as the exchange columns of hard water in the percolating method for the desalting are described In the 3rd and 4th reports, the coaly cation exchangers were used as the Catalysers of ethyl and butyl esterification of wholly hardered soyabean oil fatty acids and it Was recognized that the sulfonic acid groups of the exchangers had the catalytic activity.The conditions of esterification, the variations of activity of, catalyser in the successive uses, the esterification method in which the evolved water was removed as the boiling mixture from the reaction system, continuous esterification method, etc, were studied and the good results were obtained.In the th and 6 th reports the desalting tests of the artificial hard water in the percolating method were carried out, the pH values of effluents being measured, and the variation of the pH values of supplied water as well as the variation of activity of the exchanger in the successive employments being, studied.The results were evaluated by the neutralising curves of the coaly cation exchangers, which were designed by the potentiornetric titration of them.

  • Oxidation of Coal and Its Ignition Temperature
    Masatake Maezawa

    Analysing the various factors influencing the ignition or kindling temperatuae of coal, the author defined the latter as a temperature which might be determined from activation energy A relating to the chemical properties of coal and constant C relating to frequenecy index and coefficient of thermal conductivity, which, in turn, depend on the physical conditions.Then, the author assumed that activation energy has an intimate relationship with the degree of coalification of the sample coal and might be used as an index for classification, of coal as well as a characteristic for judgment of ignitibility, reactivity and other properties of coal or coke.

    After World War II, petroleum and natural as have been closing up as objects for materials in organic chemical industry throughout the world.Hereto- fore, these materials have been obtained from coal tar and agricultural products, how-ever, continuous wars and increasing tendency of populations have led the manufa-ctures of organic chemicals turned attentions to the petroleum and natural gas.In the technical point of view, it is presumed that during World War II, all of institu- tes and refineries in every country concentrated their efforts to obtain high octane fuel, but after the war their studies and techniques have changed toward the petro-chmicals.
    As the petrochemical products and their semiproducts are now being imported into this conutry, it would be also necessary for us to study on the line of petrochemical and then into practice for production.Such being the case, the writer have explained the history and the present situation of petrochemical in Europe and U.S.A.and on the materials, namely, refinery gas and natural gas, on the planning and purity of gas.Regarding petrochemical reactions and processes which are now being indu-strialized, the writer explained in details, showing examples on oxidation, ethylene manufacture, arornatization, alcoholization and especially processing of Shell Chemical Company's“Teepol”.
    In conclusion, petrochemical industiy is progressing day by day at the top level of technique in petroleum.refining and require extremely much amount of capitals to be invested and also much amount of crude oil, cracking gas or natural gas.It would also be necessary to take into consideration for market of products.Under the circumstances and in view of the nature of the business, the writer has concluded that it would be wise to introduce western techniques into this country.Another idea is that intermediate materials would be imported for actual production of finish products and, having had succeeded the enterprize, then the manufacturing of intermediates would also be set up.
