Ward, J W

A process is described for converting a waxy hydrocarbon feedstock containing a substantial proportion of hydrocarbonaceous material boiling above about 650/sup 0/F into a high quality lube oil stock which comprises: (a) contacting the waxy hydrocarbon feedstock with a dewaxing catalyst in a dewaxing zone under conditions such that the pour point of the feedstock is reduced, the dewaxing catalyst comprising a molecular sieve containing pores defined by 10-membered rings of oxygen atoms; (b) contacting at least a portion of the effluent from the dewaxing zone with molecular hydrogen in the presence of a hydrocracking catalyst in a hydrocracking zone under conditions such that a further reduction in pour point is effected. The hydrocracking catalyst comprises at least one hydrogenation component selected from the group consisting of Group VIB metal components and Group VIII metal components on a support comprising a crystalline aluminosilicate Y zeolite having catalytic activity for cracking hydrocarbons and a porous refractory oxide comprising silica-alumina dispersed in a matrix of gamma alumina; and (c) recovering a high quality lube oil stock from the effluent of the hydrocracking zone.
