1. A process for the preparation of unsaturated low molecular weight hydrocarbons by hydrogenating carbon oxides in the presence of catalysts, which contain 100 parts by weight of iron, 50 to 100 parts by weight of vanadium, up to 10 parts by weight of magnesium oxide and 3 to 5 parts by weight of potassium oxide, characterised in that they also contain 10 to 150 ppm sulphur (relative to the total catalyst mass). |
