Abstract
This invention relates to a hydrocarbon synthesis process comprising the conversion of a feed of H2 and 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 H2:carbon oxide molar ration in the feed of H2 and carbon oxide is at least 2.
Claims8
A Fischer-Tropsch process comprising converting a feed of H2 and at least one carbon oxide to hydrocarbons in the presence of an alkali metal promoted iron Fischer-Tropsch catalyst and an acidic catalyst suitable for converting hydrocarbons, wherein a reaction mixture formed during the conversion contains less than 0.02 mol alkali metal per 100 g iron and the H2:carbon oxide molar ratio in the feed of H2 and carbon oxide is at least 2.
