PREPARATIONS OF HYDROCARBONS

摘要

C9<+> 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 C8<-> hydrocarbon by-products and steam is separated from the synthesized product and recycled to the steam reformer.
