Abstract
A process is provided for the production of hydrocarbons from synthesis gas wherein the synthesis gas is fed to a reactor in which a catalyst acts on the feed at a temperature of between 160° C. and 400° C. and a pressure of between 1 bar and 5 bar. The feed includes a compound containing one or both nitrogen and phosphorus added to the reactor with the synthesis gas. The compound containing nitrogen typically constitutes at least 1 vol % and preferably of the order of 4 to 20 vol % or more of the feed. The carbonaceous gas may be carbon monoxide with a ratio of hydrogen to carbon monoxide in the synthesis gas of from 0.5:1 to 5:1. The catalyst is preferably a supported cobalt catalyst and may be modified with a promoter. The process produces an enhanced proportion of olefins, in the hydrocarbons produced.
