The effect of decationized forms of zeolites (ZSM, NaY and clinoptilolite) on the hydrocracking and hydroisomerization activity of alumina catalysts modified by metals in the n-decane conversion has been shown. The synthesized catalysts were studied in a laboratory flow reactor at temperature of 350-500C and P= 2.0 MPa and feeding flow rate = 2.0-6.0 hr-1. It has been established that both n-decane conversion and selectivity of isomer formation depend on the nature of modified additives. The GK-3 catalyst synthesized on the base of high silica ZSM-zeolite has the most cracking and isomerization activity.
