## Abstract

The invention relates to a process for preparing olefins from synthesis gas, wherein the synthesis gas is contacted with a catalyst which contains cobalt, manganese and a third element selected from the group consisting of aluminium, gallium, indium, thallium, tin, lead and bismuth. Further, the invention relates to a process for preparing such catalyst, and to the catalyst so obtained.

## Claims

### Claim 1

Process for preparing olefins from synthesis gas, wherein the synthesis gas is contacted with a catalyst which contains cobalt, manganese and a third element selected from the group consisting of aluminium, gallium, indium, thallium, tin, lead and bismuth.

### Claim 2 (depends on 1)

Process according to claim 1, wherein the catalyst contains cobalt, manganese and tin.

### Claim 3 (depends on 1)

Process according to claim 1, wherein the catalyst is pre-reduced at a temperature within the range of from 400 to 500° C.
