Activity and selectivity of Ni/ZSM-5+Al2O3 catalyst (8 wt.% NiO) containing 30 wt.% Ni,H-ZSM-5 were compared to those of catalysts to which USY zeolite, Ni,H-ZSM-5 zeolite, and heteropoly acid were added (20%). The ZSM-5 containing catalyst modified with heteropoly acid was less active than those modified by zeolite (USY, ZSM-5). N-Hexane conversion was highest for the catalyst contg. 50 wt.% zeolite. The yield of hydrocracking products was higher for the catalyst contg. 50 wt.% ZSM-5 than that of catalyst containing 30 wt.% ZSM-5 and 20 wt.% USY zeolites. Modification of the ZSM-5 containing catalyst did not result in higher yield of isomerization products.
