508. D’OUVILLE, E. I. (Koppers Co., Inc.). Manufacture of Hydrocarbons. United States Patent 2,499,372. Mar. 7, 1950; appl. filed Mar. 9. 1946, Serial No. 653,406: 7 claims (Cl. 260-449.6).

CO and H₂ are passed into contact with a sintered FE catalyst at 300°-350° C. at a pressure 10-50 atm. and a velocity 300-5,000 vol, synthesis gas per vol. catalyst per hr. The synthesis gas is CO: H₂:4:3 or 2:1 or 1:1. A final synthesis gas containing CO and H₂ in a ratio not greater than 1:0.65 nor less than 1:1 will produce a residue gas having a CO₂ content useful for production of 2 synthesis gases. 1 by reaction of residue with CH₄ and steam and the other by reaction of the residue gas with coke. The 2 synthesis gases are mixed. 1 foreign and 8 United States patents cited.
