    After a brief retrospection about the import of crude oils into Japan before the late War and the properties of those imported crudes, the author presented the test results of the Arabian (Ahquaiq) crude which had been firstly imported by the Nihon Oil Co.after the War, and also the operation data with that crude at the Kashiwazaki refinery of the same company.
    The, author said that the Arabian crude was paraffinic and rich in sulphur, its gasoline fraction had a lower octane number, its gas.-oil fraction was of good quality as Diesel fuel, the paraffin wax-which yield being about 2% of the crude-was rich in the component of higher melting point, the lubricating oil of high viscosity index was obtained by dewaxing followed by sulphuric acid and clay treatment from the residual oil, and the asphalt was inferior.The attempt of protecting equipments from the corro-sion with the sulphur compounds in the crude was explained.The analytical results of these compounds in the gasoline and kerosene fractions were showed.
    Then, it was briefly described about the permission of G.H.O.for the reopening of the Pacific coast refineries as well as the import of crudes, and the recent plan for the import and refining of crudes.Several problems about these items, i.e., the comparison of Japanese crudes with Arabian crudes in price and quality, the refin-ingequipments and their management etc., were also discussed.

    Before the late War a considerable amount of the Middle East crude oil, namely Bahrein, Saudi Arabia or Iran crude, had been imported for refining in this country.The property of the Middle East crude oil is characterized by some, differences from that of the other area's oil. As a rule, that crude oil is of inter-mediate base and rich in sulphur, gasoline fraction has low octane number, kerosene fraction is good for lump use, gas-oil fraction is of high cetane number, lubricating-oil of high viscosity index is obtained from residual oil, and the cracked gases of naphtha and kerosene are to be used for the purpose of alkylation, polymerization and petrochemicals making.The Kuwait crude oil, as the crude oil of the first commercial import after the War, was delivered to the Kawasaki Refinery of Showa Oil Co.on Jan.15, 1950.The results of the laboratory test and actual topping operation (4, 000 bbl/D) with that crude were showed. Finally, judging from the current world situation of demand and supply of crude oils, the author presumes that the Middle East oil fields will be the very source from which Japan can be provided with crude oil for the forthcoming several rears.

    The comparison of the evaluation method of oils by U.O.P.charac-terization factor, viscosity-gravity constant and viscosity index with the classification method of crude oils proposed by U.S.Bureau of Mines was carried out Then, the author showed the diagram drawn by him for determining the“base”of petro-leum by the gravity and boiling temperature or viscosity, and described its application.The change of nature of crude with the geological age and the depth of well, from which it was obtained, was explained according to the data of the oil fields in the world.
    Lastly, the importance of investigations at the refineries in this country was pointed out, and a way to improve the present situation was proposed.

    The author described on the details of the characteristics of synthetid lubricating oils from the olefines which were prepared by the decomposition and refining of the fatty acids of coconut, palm and chrysalis oil, and also discussed the optimum conditions of preparation.
    The decompositions were carried out on the following conditions: the reactions: -vapour phase, pressures: -atmospheric, decomposition agents: -the mixture of 100% active clay and 25% calciumoxide or bariumoxide, and temperatures: -about 450-500°C.The polymerization agent of refined olefine was anhydrous aluminium chloride.
    The stabilities of these synthetic lubricating oils were examined in detail and they were recognized as the good lubricating oil for automobile or other internal com-bustion engines.

    After describing the differences between the petroleum gas wet gas and the natural gas (dry gas) in Japan-the developement of the latter having been promoted eagerly after the 2nd Warsthe author explained the geological suroundings of the methane bearing strata, the formation condition of the deposit and the clas-sification of its structure upon the gasfield in various districts.The methane reserve in Japan is 75×109m3 and its availavility is very promising.The most important problem is the improvement of the excavation technique.The yield of the gas has suddenly increased after the War, particularly in Niigata Prefecture, and about the third of itas consumed as motor fuel.Among the other possible uses, the new chemical applications, such as the synthesis of vinyl acetate and ethanol are taken into consideration.

    The author described on the details of the laboratory and pilot plant tests on the electric Arc decomposition of the natural gas, their capacities being 100 KW and 1, 000 KW as electric povier.The chemical engineering, problems of the de-composition vessel, especially the relations between diameter, number and position of nozzle or between diameter and length of the reaction tower were elucidated.The exit gas containing 15% of acetylene was purified to 96% by scrubbing with Water at 20 atm and exhausting of hydrogen at 5 atm. The crude hydrogen from the exhaust tower was separated into hydrogen and hydrocarbon after hydrogenation.
    Then, the author discussed the low cost of acetylene by the electric process, saying that it should be about 18.2 Yen per m3, markedly cheaper than that by the caibide process, about 52 Yen per m3, on the assumption that the new plant had been constructed in Niigata district.
