Abstract

Hydrocarbons are synthesised from hydrogen and carbon monoxide (preferably in a volume ratio greater than 1:2 and at 5-50 atm. and 250 DEG -350 DEG C.) in e.g. a fluidized fixed bed or a slurry system in presence of a solid unreduced alkali-promoted iron oxide catalyst, which has been subjected to at least incipient melting temperature, of particle size up to 200 m (e.g. 100-200 m , 65 m or less, or 5 m or less) which has been subjected to ionizing radiation, preferably at least 103 and particularly at least 105 Roentgens. The following features are preferred: (a) the catalyst is based on an alkali-impregnated steel rolling-mill scale, particularly where the latter is impregnated with potassium carbonate and calcined for 4 hours at 1000 DEG -1300 DEG C.; (b) the radiation consists of either gamma rays, particularly those derived from cobalt 60 and of energies 1,17 and 1,33 MEV or high energy electrons, particularly of energy about 16 MEV; (c) the irradiation is effected in an inert gas such as nitrogen, or air or oxygen, or in carbon monoxide or hydrogen, the irradiation atmosphere being preferably at substantially normal, or less than normal, pressure.ALSO:Hydrocarbons are synthesised from hydrogen and carbon monoxide (preferably in a volume ratio greater than 1 : 2 and at 5-50 atm. and 250 DEG C.-350 DEG C. in, e.g. a fluidised fixed bed or a slurry system in presence of a solid unreduced alkali-promoted iron oxide catalyst, which has been subjected to at least incipient melting temperature, of particle size up to 200m (e.g. 100m -200m , 65m or less, or 5m or less) which has been subjected to ionising radiation, preferably at least 103 and particularly at least 105 Roentgens.
