Partridge, R D; LaPierre, R B

A process is described for increasing the selectivity of the production of higher boiling distillate range product in hydrocracking reactions which can produce gasoline boiling range product and higher boiling distillate range product, which process comprises: contacting a feedstock to be hydrocracked in a hydrocracking, in the presence of hydrogen and under hydrocracking conditions, with a catalyst comprising a hydrogenation component and a zeolite which has a porous lattice structure having pores with a dimension greater than 6 Angstroms and a hydrocarbon sorption capacity for hexane of at least 6 percent and has a framework silica:alumina ratio of at least about 50:1, whereby the selectivity of the process for production of the higher boiling distillate range product is preferentially increased, wherein the distillate selectivity is defined by reference to the amounts of the 165/sup 0/C-343/sup 0/C (330 F-650/sup 0/F) fraction and the total 343/sup 0/C-fraction in the hydrocracker effluent.
