PREPARATION OF HYDROCARBONS

摘要

C5<+> hydrocarbons are prepared from C4<-> hydrocarbons by a two-stage process comprising steam reforming followed by Fischer-Tropsch synthesis over a special cobalt-containing catalyst; a gaseous fraction comprising unconverted H2 and CO as well as C4<-> hydrocarbons and CO2 formed as by-products is separated from the synthesized product and recycled to the steam reformer.
