ABSTRACT:
A process for preparing and using a cobalt slurry phase Fischer-Tropsch synthesis catalyst includes introducing a modifying component Mc into a catalyst support precursor, followed by shaping and calcination, to obtain a catalyst support. The catalyst support is impregnated with an aqueous solution of a cobalt salt, to form an impregnated support which is partially dried and calcined, to obtain a catalyst precursor. The catalyst precursor is reduced to form a cobalt slurry phase Fischer-Tropsch synthesis catalyst. A synthesis gas is contacted with this catalyst in a slurry phase Fischer-Tropsch synthesis reaction at elevated temperature and elevated pressure, and a clean wax product that contains less than 50 mass ppm submicron particulates of cobalt is obtained.
