Abstract
A process for the preparation of a composition comprising oxygenates and hydrocarbons by means of a Fischer-Tropsch synthesis reaction, said process comprising contacting a mixture of hydrogen, carbon monoxide, and carbon dioxide gases with a supported Co—Mn Fischer-Tropsch synthesis catalyst, wherein the supported synthesis catalyst comprises at least 2.5 wt % of manganese, on an elemental basis, based on the total weight of the supported synthesis catalyst; the weight ratio of manganese to cobalt, on an elemental basis, is 0.2 or greater; and, wherein carbon dioxide is present in the Fischer-Tropsch synthesis reaction is at least 5% v/v.
