Abstract

Abstract A hydrocarbon conversion catalyst is prepared by mixing about 10-90%wt of channel pore structure zeolite with about 90-10%wt of three-dimensional pore structure zeolite, decationizing the zeolites either before or after mixing to reduce the alkali metal content to less than about 0.5%wt, then incorporating a catalytic amount of a hydrogenation metal component into the mixed zeolites.
