Process for preparing a catalyst for reducing carbon monoxide

Abstract

Abstract A catalyst containing iron or a mixture of iron with copper as its active ingredient, made by precipitating a complex salt of the general formula: Me.sub.x [Fe(CN).sub.6 ].sub.y in which Me stands for an iron and/or copper ion, X stands for 1, 2, 3 or 4, and y stands for 1, 2 or 3; separating and drying the precipitated salt, and reducing the salt by contacting it with at least stoichiometric proportions of hydrogen or a mixture of hydrogen and carbon monoxide, for use in the reduction of carbon monoxide by means of hydrogen with the resultant formation of a mixture consisting substantially of C 1 -C 4 hydrocarbons is modified. The modified catalyst is formed (a) by subjecting the precipitated and dried salt to thermal decomposition at a temperature of 200° to 500° C. in the absence of hydrogen or a mixture of hydrogen and carbon monoxide, or (b) mixing the precipitated and dry salt with a carrier, tabletting, pelletizing or extruding the resulting mixture and reducing it by means of hydrogen or a mixture of hydrogen and carbon monoxide, or (c) mixing the precipitated and dry salt with a carrier, tabletting, pelletizing or extruding the resulting mixture and thermally decomposing it at 200° to 500° C. in the absence of hydrogen or a mixture of hydrogen and carbon monoxide.
