    The author described the status quo of shale.oil industry-and coal hy-drogenation in U.S.A.and discussed the possibility of the economical development of these processes.
    Shale oils are produced in the scale of 3, 000bbl/day per one plant now, and if the scale is extented to 10, 000bbl/day and 60 percent of its products is the fuel for jet engine, it may cost 9 cent/gal.It is cheeper than that from petroleum.
    The pilot plant of high pressure hydrogenation of coal which capacity is 200 to 300bbl/day was constructed recently at Louisiana in Missouri SThte. Concluding from its operation result, when a plant of 30, 000bbl/day is operated, motor gasoline being produced mainly, its price may be 14.5cent/gal and dearer than that from petroleum but when aviation gasoline is main product, its price may be 16.6 cent/gal, so a considerable depression of cost be attained by mechanization of mining, improvement of catalyst, etc.
    From his experiences at the Agochi coal hydrogenation plant in war time, the author presented some technical advices on the operation of the Lousiana plant.

  • On the Combustion of Solid Fuel

    The author Classified the combuston of solid fuel from comparing the burning velocity into three types of (i) surface combustion, (ii) decomposing com-bustion and (iii) evaporating combustion.
    Coke, anthracite, charcoal etc. have less volatile matter and their combustion be-longs to type (i).They are not pure carbons but rather a sort of carbon compounds nevertheless their initial reaction could be considered as one of the combustion of solid carbon.
    In the decomposing combustion of solid fuel such as coal, lignite, wood etc., they are dehydrated at the initial stage, then slowly oxidized and finally ignited.They are thermally decomposed at the ignition point, then combustion of gases formed occurs accompanying the combustion of solid fuel material.These combustions are situated between those of solid carbon and hydrocarbon but the initial reactions may be simillar to that of higher hydrocarbon. Paraffin gives an evaporating combustion which is characteristic to the combustion of hydrocarbon.
    The burning velocity of solid fuel is controlled by the rate of chemical reaction at low temperature and by the diffusion velocity of air at high temperature.These results have been showed by the other researches, but at higher temperature the greater parts of solid fuel must be changed to solid carbon and at the same time the graphitization of amorphous carbon must occur, so the mechanism of combustion at higher temperature must be entirely different from the one at low temperature and the burning velocity is again controlled by the reaction rate.The reaction has a tendency to be disturbed by the poisonous action of combustion products at more higher temperature.

  • Complete Gasification under Pressure with Steam and Oxygen

    Theoretical considerations indicated and laboratory experiments proved that, if carbon is gasified with steam and oxygen under pressure, not only the oxydes of carbon and hydrogen are formed, but also methane.Therefore the gas has a cons-iderably higher heating value than ordinary water gas. These considerations confirmed by laboratory experiments resulted in the unique process of pressure gasification de-veloped by the “LURGI” in Germany.The first industrial scale plant by this process was built in 1936, the second one in 1940 with the daily production capacity of 465, 000m3 gas and the third one in 1942 with the daily production capacity of 250, 000m3 gas.Brown coal is used as raw material in these plants and the only pro-duct of the gasification, beside some tar and light oil, is gas with a heating value of 3, 900kcal/m3 on the avarage.Full scale tests sho wed that not only brown coal, but also bituminous coal and even anthracite can be used as raw materials.The process would have a great importance in Japan, it allows the making of a high calorie gas without using caking coal, but from a low grade coal and having only tar and light oil as by-products.Such gas is suitable as utility gas, as industrial heating gas and as starting material for the making of sythesis gas.
