Abstract
A method for performing synthesis gas conversion is disclosed which comprises contacting synthesis gas with a hybrid Fischer-Tropsch catalyst formed by impregnating a ZSM-12 zeolite extrudate using a solution, for example, a substantially non-aqueous solution, comprising a cobalt salt and activating the impregnated zeolite extrudate by a reduction-oxidation-reduction cycle. The method results in reduced methane yield and increased yield of liquid hydrocarbons substantially free of solid wax.
