Two synthetic-gasoline plants of the Fischer process are being hastily constructed by the Mitsui Mining Co. at Miike and by the Manchurian Synthetic Fuel Co. at Chinchou. Both plants are of a similar capacity – 30,000 tons of synthetic gasoline per yr. – and it is reported that they are nearly completed. Recently the Hokkaidō Artificial Petroleum Co. was established in cooperation with the Imperial Fuel Industry Co., with a capital of 70 million yen. The plant to be constructed by this concern will have a production of 140,000 tons of synthetic oil per yr. and will be erected by the end of 1940. As a semi-industrial test of the synthesis under pressure, continuous investigations are being carried out by the Imperial Fuel Research Institute on 3 types of reaction chambers made of 4 Fe tubes 25 mm. inside diameter and 560 mm. long, 2 tubes 35 mm. inside diameter and 510 mm. long and 1 tube 55 mm. inside diameter and 520 mm. long were constructed and tested. The reaction chamber was heated by circulating outside the chamber machine oil of high flash point, heated to the desired temperature. The catalyst used was Co-Cu-Th-U-kieselguhr, 100:12.5:2.5:1.25:1.25, prepared by the precipitation method and formed in tablets. The gas velocity was 100 l. per hr. in all cases. Where the inside diameter of the reaction tube was 25 mm. and 35 mm., the yield of gasoline was 98 cc. per m.³ and 78 cc. per m.³, as compared with 110 cc. per m.³ and 101 cc. per m.³ in the small-scale experiments, but it decreased rapidly to 40 cc. per m.³ in the case of the 55-mm. tube. It was concluded that the use of such a large-diameter tube is difficult. Based on the results of the investigation, the capacity of the reaction chamber was enlarged so as to be able to treat 10 m.³ of raw gas per hr. A mixture of water gas and electrolytic H₂ was used, the average organic S content of which was reduced to 1.05 gm. S per 100 m.³ with a Luxmasse-NaOH-Cu(OH)₂ (100:10:10) at about 200° C. The test was continued for about 10 days. The average gasoline yield was 81-85 cm.³ per m.³ (100 cm.³ per m.³ pure base), compared with 120 cm.³ per m.³ in the small-scale experiment.
