Abstract

Method of activating a catalyst composite comprising particles of a catalytic metals-free crystalline zeolitic molecular sieve dispersed in a gel matrix comprising silica-alumina, a Group VI hydrogenating component and a Group VIII hydrogenating component, which method comprises heating said catalyst composite in an oxygen-containing gas stream at 1200.degree. to 1600.degree. F. for 0.25 to 43 hours, and the catalyst composite so activated.
