Ward, J W

A process is described for hydrocracking a hydrocarbon feedstock to produce a product of lower average boiling point. The process comprises contacting the hydrocarbon feedstock with molecular hydrogen under ammonia-deficient hydrocracking conditions in the presence of a catalyst comprising an intimate mixture of a porous refractory oxide component and a type Y crystalline aluminosilicate zeolite containing a rare earth metal and a Group VIII hydrogenation metal. The zeolite is prepared by a process comprising: (a) cation-exchanging a type Y crystalline aluminosilicate zeolite with rare-earth containing cations; (b) calcining the resultant rare earth-exchanged zeolite in the presence of water vapor at a water vapor partial pressure of at least about 0.2 psia; (c) ion-exchanging the calcine zeolite from step (b) with ammonium ions; and (d) ion-exchanging the ammonium-exchanged zeolite from step (c) with Group VIII metal-containing cations.
