ABSTRACT:
A process is described for producing gasoline from a paraffinic hydrocarbon feed wherein the feed is catalytically cracked and then reformed. In the process a novel porous hydrocracking catalyst composite is employed. This catalyst comprises a silica-alumina cracking base component and a noble metal hydrogenation component. It is stabilized as a result of a unique method used for introducing the noble metal in the form of a highly dispersed gravimetric precipitate into a gelatinous silica-alumina cogel precursor of the cracking base component. An organic gravimetric reagent is used for the precipitation. The resulting crackate is reformed by ordinary methods.
