ABSTRACT:
The product of Fischer-Tropsch Synthesis is separated to recover a C.sub.5 -400.degree. F liquid fraction which is thereafter hydrogenated in order to saturate diolefins and contacted with a ZSM-5 type zeolite under conditions of elevated temperature and pressure so as to obtain gasoline of a higher octane rating. The contact with the ZSM-5 zeolite is preferably in the presence of added hydrogen.
