1777. 1777. JOHNSON, E. A., AND BECKER, S. B. (Standard Oil Co. of Indiana). Method and Means for Hydrocarbon Synthesis. United States Patent 2,460,508, Feb. 1, 1949; appl. filed July 30, 1946, Serial No. 687,064; 2 claims (Cl. 260-449.6). Chem. Abs., vol. 43, 1949, p. 3175.

One portion of a mixed stream of CO and H₂ gases, ratio 3:5 is reacted over a Co synthesis catalyst at 340°-500° F. and 1 atm. pressure, and another portion of this stream is reacted over an Fe synthesis catalyst at 400° F. and 5 atm. Residual gas from the Co catalyst zone is supplied to the Fe catalyst zone. At least a portion of the H₂-rich gas recovered from the Fe catalyst zone is supplied after separation of Co₂ to the Co catalyst zone. Increased outputs in hydrocarbons and other conversion products are obtained by this combined process. A flowsheet is included. 1 foreign and 4 United States patents cited.
