Abstract
A process and catalyst 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 hydrogenation metals and a support comprising zeolite Y. The hydrogenation metals comprise from about 0.1 percent to about 2.0 percent by weight each of palladium and platinum calculated as a percentage of the catalyst. The zeolite Y further comprises sodium in an amount ranging from about 1.5 to about 8.0 percent of the zeolite Y by weight. The process of the present invention provides substantially improved dearomatization performance, increased desulfurization and denitrogenation, increased distillate product cetane number, and increased distillate volume expansion.
