296. CAIN, V. L., AND HEMMINGER, C. E. (Standard Oil Development Co.). [Catalytic Production of Hydrocarbons From Carbon Monoxide and Hydrogen.] French Patent 963,531, July 12, 1950: appl. filed Mar. 22, 1948, in United States May 9, 1947. Chem. Zentralb., 1950, II. P. 2271.

Operation is carried out with a Fe catalyst, such as us used for NH₃ synthesis, under a H₂ partial pressure of 10.5-19 atm. with a synthesis gas that contains H₂ and CO in proportions of 2:1. The temperature in the reaction zone is kept high enough to form essential amounts of olefins. The fluidized catalyst is pretreated before us e with a CO-rich gas at temperature about 55º below the synthesis temperature.
