Claims
- 1. In a process for the production of hydrocarbon mixtures containing predominantly olefins comprising catalytic conversion of a feed gas comprising carbon oxides and hydrogen in the presence of a catalyst containing iron and those oxides of vanadium and/or manganese which are difficult to reduce at elevated temperatures and pressures, the improvement which comprises carrying out said conversion at a temperature of 250.degree. C. to 350.degree. C. and under a pressure of 10 to 30 bars, in the presence of a catalyst consisting essentially of 100 parts by weight of iron, and 50 to 100 parts by weight of an oxide of manganese and/or vanadium, said oxide being difficult to reduce, said catalyst including 3 to 5 parts by weight of K.sub.2 O, and 5 to 15 parts by weight of ZnO.
- 2. The process according to claim 1 wherein said oxide is of manganese.
- 3. The process of claim 1 wherein said catalyst further comprises at least one carrier.
- 4. The process according to claim 1 wherein there is a carrier present selected from the group consisting of silicic acid, kieselguhr, aluminum oxides, aluminum oxyhydrate, and silicates.
- 5. The process according to claim 1 wherein magnesium oxide is present as an additional promoter.
- 6. The process of claim 1 wherein said olefins contain 2 to 4 carbon atoms.
- 7. The process according to claim 4 wherein said silicates are selected from magnesium silicate, aluminum silicate, or pumice.
