      969.  ------.  [HEMMINGER, C. E.]  (Standard Oil Development Co.).  [Catalytic Synthesis of Hydrocarbons From Carbon Monoxide and Hydrogen.]  French Patent 960,868, Apr. 26, 1950: appl. filed Feb. 9, 1948, in United States Mar. 21, 1947.  Chem. Zentralb., 1950, II, p. 2270.

            Synthesis is carried out under pressures of 10.5-105 atm. and at temperatures 370º-425º, preferably 370º-400º.  The fluidized Fe catalyst contains 0.1-1.5 wt. % of K2O reckoned on the Fe2O3.  The ratio of CO : H2 = 1.9 : 0.7 at a throughput of synthesis gas of 1.24-3.12 l. per kg. of catalyst per hr.  The Fe catalyst has the following composition, in parts by weight : Fe, 67.1 : O2 (combined with the Fe), 26.1 : Al2O3, 2.57: SiO2, 1.37; MnO, 0.85; K2O, 0.90; MgO, 0.11; CuO, 0.10; NiO, 0.05; particle size 0-20μ 20%, 20-40μ 17%, 40-80μ27%, and more than 80μ 36%; conversion of CO 92.5-95.2%.  The products consist of 6.1% C1-, 8.4%  C2-, 95.2%.  The products consist of 6.1% C1-, 8.4% C2-, 11.1% C3-, 65.4% C4-hydrocarbons, and 9.0% oxygenated compounds.  The C4-fraction consists of 25% C4-, 63% C5-hydrocarbonsm with a boiling point up to 204º and 12% above 204º.  The octane No. is 75.7.
