676. ------. [FISCHER, F., AND PICHLER, H.] (Hydrocarbon Synthesis Corp.), Hydrocarbons From Gases Containing Carbon Monoxide and Hydrogen. United States Patent 2,257,457, Sept. 30, 1941; appl. filed July 23, 1938, Serial No. 220,919, in Germany July 31, 1937; 9 claims (Cl. 260-449). Chem. Abs., vol. 36, 1942, p. 250.

Process of producing aliphatic solid, liquid, or readily liquefiable hydrocarbons from gas mixtures containing CO and H₂ in the presence of an Fe catalyst comprises passing a mixture of CO and H₂ under an operating pressure of 2-100 atm. and at 220º-320º over an Fe catalyst that has been subjected to a preliminary treatment with CO under a pressure considerably lower than the operating pressure subsequently employed.
