Abstract
High-silica pentasil zeolites with the silicate module from 20 to 200 were synthesized. Basing on them, catalysts have been prepared those contain nickel, zirconium and platinum introduced using various ways. An effect of the zeolite silicate modulus and modifying exerted on the acidity and activity of zeolite catalysts in the course of n-octane isomerization were studied. Optimal conditions for the isomerization of n-octane in the presence of catalysts under investigation have been determined.
