Abstract

Reduction of carbon monoxide by means of hydrogen with the resultant formation of a mixture of hydrocarbons having substantially from 1 to 4 carbon atoms in contact with a catalyst containing iron or a mixture of iron and copper as its catalytically active ingredient, the catalyst being made by contacting one or more complex salts of the following general formula: EQU Me.sub.x [Fe(CN).sub.6 ].sub.y in which Me stands for an iron and/or copper-ion, x stands for a number of 1 to 4, and y stands for a number of 1 to 3, with hydrogen or a hydrogen/carbon monoxide-mixture at about 200.degree. to 500.degree. C., under 1 to 100 atmospheres absolute and over a period of about 2 to 20 hours and thereby reducing the complex salts substantially to elementary iron or copper.
