PROCESS FOR THE PREPARATION OF HYDROCARBONS HAVING AT LEAST NINE CARBON ATOMS PER MOLECULE FROM HYDROCARBONS HAVING AT MOST FOUR CARBON ATOMS PER MOLECULE

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.
