United States Patent 2,369,548, Feb. 13, 1945; appl. filed Feb. 25, 1942, in Belgium Mar. 4, 1941 (Cl. 260-449.6). Chem. Abs., vol. 39, 1945, p. 3147. Preparation of an Fe, Co, or Ni carbide catalyst promoted by Cu oxide for the Fischer-Tropsch synthesis. The pure metal in a finely divided state is introduced in a tube made of steel, ceramic, or quartz and heated in an electric oven to 250º-450º C. while passing a gas, CO, CH4, etc., capable of giving up its C or using C itself in a sealed tube and constantly rotating the tube. Then the carbide is cooled, using an inert gas, N2, He, very rapidly to a very low temperature, preferably lower than -190º C., and then crushed and a suitable amount of powdered Cu or alkali metal oxide is added and the carbide is agglomerated under pressure while heating moderately. Using Fe carbide prepared in this manner, 155 gm. of hydrocarbons for each m.3 of water gas used are obtained. |
