[Catalytic Production of Hydrocarbons From Carbon Monoxide and Hydrogen.] French Patent 963,475, July 11, 1950: appl. filed Mar. 19, 1948, in United States June 11, 1947. Chem. Zentralb., 1950, II, p. 2271. Operation is preformed with an Fe catalyst at 289º-427º and under 5-50 atm. The catalyst consists of a precipitated, reduced Fe oxide or of reduced pyrite residue, which have been activated by addition of the oxides, hydroxides, carbonates, chlorides, or fluorides of Na or K. Other suitable catalysts are those used in the synthesis of NH3 from N2 and H2 and contain 1.5% of Al2O3. The quantity ratio of CO : H2 in the synthesis gas is 1 : 0.5-3.0. The liquid hydrocarbon oil formed in the synthesis, which contains considerable amounts of unsaturated hydrocarbons, is subjected to a cracking treatment on bauxite at 427º-537º and 1-10 atm., whereby mainly the hydrocarbons of the gas oil series are cracked, and the proportion of light hydrocarbons is increased. The bauxite used for the cracking catalyst is activated by dehydrating at 537º-649º, to a H2O content <10%, preferably <3%. |
