3857. WALDEN, G.H., PIERCE, J.A., SEGURA, M.A., WATTS, R.N., AND SPICER, W.L. (Standard Oil Development Co.). [Catalytic Production of Hydrocarbons From Carbon Monoxide and Hydrogenation.] French Patent 952,815, Nov. 24, 1949, appl. filed Sept. 9, 1947; in the United States, Nov. 27, 1946. Chem. Zentralb., 1950, II, p. 961.

To produce hydrocarbons from CO and H₂, a reduced fluidized catalyst of Fe, Ni, or Co metals is used. When using Fe, KF, or K₂CO₃ is added as promoter. To produce an active catlyst, it is oxidized at 1,650° -1,925° to form the oxide and then reduced at about 480° . A suitable catalyst contains, for example, 96% powdered Fe, 3% Al₂O₃ and 1% K₂CO₃, or 91% powdered Fe, 4.45% KMnO₄, 2.27% SiO₂, and 2.27% TiO₂.
