        Review of the various methods of producing motor fuel from coal, indicating the present state of commercial operation of the Bergius process, the Fischer-Tropsch synthesis process, and extraction processes such as the Pott-Broche and Uhde.  In current Fischer-Tropsch synthesis, the refined liquid products consist of 62% gasoline of low octane number and low lead susceptibility, 26% Diesel oil of very high cetane number, 10% gas, and 2% paraffin wax.  the theoretical yield of liquid products is 13 lb. per 1,000 cu. ft. of gas treated; the actual yield is 7.5 lb. (1.2 gal.) but he modified Fischer-Pichler process yields 9.4 lb.  In 1938 Germany was operating 14 Fischer-Tropsch plants with a capacity of 7,000,000 bbl. per yr.
