881. ------. [GRIFFIN, L. I., JR.] (Standard Oil Development Co.). [Catalytic Production of Hydrocarbons From Carbon Monoxide and Hydrogen.] French Patent 954,643: appl. Filed Oct. 24, 1947. issued Dec. 28, 1949. in United States Nov. 9, 1946. Chem. Zentralb., 1950. II, p. 488.

Hydrocarbons are synthesized from CO and H₂ with simultaneous introduction of steam. Fe, Ni, or Co in suspended fluidized form is used as the catalyst. Fe being preferred. A part of the catalyst is removed from the reaction zone during the synthesis, regenerated, and returned to the process to avoid as far as possible the deposition of C on the catalyst. The operating temperature lies 260°-399° and at a pressure of 52.5 atm.
