HYDROCARBON SYNTHESIS PROCESS USING AN ALKALI PROMOTED IRON CATALYST

摘要

This invention relates to a hydrocarbon synthesis process comprising the conversion of a feed of HSUB2 /SUBand at least one carbon oxide to hydrocarbons containing at least 30% on a mass basis hydrocarbons with five or more carbon atoms. The conversion is carried out in the presence of an alkali-promoted iron hydrocarbon synthesis catalyst and an acidic catalyst suitable for converting hydrocarbons. The reaction mixture formed during the conversion contains less than 0.02 mol alkali per 100 g iron and the HSUB2/SUB:carbon oxide molar ration in the feed of HSUB2 /SUBand carbon oxide is at least 2.
