British Patent 496,880, Dec. 5, 1938. Chem. Abs., vol. 33, 1939, p. 3380. Hydrocarbons of more than 1C atom and/or O-containing derivatives of hydrocarbons, for example, alcohols, ketones, esters, acids, and aldehydes, are obtained for bringing CO and H2 into contact at a reacting temperature with a catalyst prepared, before the reaction, by reduction of a compound of an Fe group metal that is reducible to metal <500º with a reducing gas at <500º and treatment of the reduced substance in the absence of an oxidizing gas at such a temperature >500º but < the melting point and for such a time that at least a partial sintering occurs. In an example, precipitated Fe(OH)3 mixed with Al(OH)3 is reduced with H2 at 450º and then heated for about 3 hr. at 850º with N2; it is used for the conversion at about 320º and 15 atm. of CO and H2 in the ratio of 1:2 into mainly gaseous, liquid, and solid hydrocarbons.
