Abstract
A process and catalyust are provided for hydrogenation of a hydrocarbon feedstock consisting essentially of material boiling between about 150.degree. F. and about 700.degree. F. which comprises reacting the feedstock with hydrogen at hydrogenation conditions in the presence of a catalyst comprising from about 0.1% to about 2.0% by weight each of palladium and platinum and a support comprising mordenite. The process of the present invention provides substantially improved dearomatization performance, increased desulfurization and denitrogenation, increased distillate product cetane number, increased distllate volume expansion, and utilizes a more durable catalyst.
