1660. ------. [INTERNATIONAL HYDROCARBON SYNTHESIS CO.] Conversion of Carbon Monoxide With Hydrogen Into Hydrocarbons. British Patent 538,225, July 25, 1941; appl. filed Nov. 6, 1939. Chem. Abs., vol. 36, 1942, p. 2119.

Conversion of CO and H₂ into liquid, solid, or gaseous hydrocarbons is carried out in the presence of Fe catalysts. Compact Fe is treated with oxidizing gases at 700º-900º and for such a long time that the Fe is substantially completely converted into Fe oxide without melting of the Fe of the Fe oxide formed, and, subsequently, the Fe oxide is reduced to metal by treatment with reducing gases to secure the catalyst for the process. The temperature of the aforesaid reduction is 500º. Additions of alkali metal compounds increase the activity of the catalyst. This catalyst may also be used for high-pressure hydrogenation of oil.
