2562. ------. [OWEN, J. J.] (Standard Oil Development Co.). Pretreatment of Gases for the Synthesis of Hydrocarbons. United States Patent 2,468,510, Apr. 26, 1949; appl. filed Dec. 14, 1945, Serial No. 635,099; 4 claims (Cl. 260-449.6). Chem. Abs., vol. 43, 1949, p. 7214.

Feed stock of impure CO and H₂ is contacted under suitable conditions with a solid desulfurization agent, such as Cu carried on Al or Mo, which does not form a metal carbonyl under these conditions. The purified feed gas is thereafter directly treated under hydrocarbon synthesis conditions in the presence of a fluidized synthesis catalyst while preventing the entry of desulfurizing agent into the synthesis zone. 1 literature ref. and 5 United States patents cited.
