1. A catalyst system, comprising:
a hydrocarbon synthesis catalyst comprising 5.0 wt % or more cobalt on an oxide support, relative to the weight of the oxide support; and
an acid catalyst having an Alpha value of 2.0 to 100 comprising an amorphous oxide, a zeotype framework with a pore channel size of 6.5 Angstroms or more, or a combination thereof,
the hydrocarbon synthesis catalyst and the acid catalyst comprising a catalyst mixture having a weight ratio of the hydrocarbon synthesis catalyst to the acid catalyst between 0.1 and 9.0,
wherein the acid catalyst further comprises 0.1 wt % to 5.0 wt % of a hydrogenation metal supported on the acid catalyst, relative to the weight of the acid catalyst or wherein the hydrocarbon synthesis catalyst further comprises 0.05 wt % to 2.0 wt % of a promoter metal relative to the weight of the hydrocarbon synthesis catalyst or a combination thereof.
