Abstract:
1. A process for upgrading a hydrocarbon feedstock containing waxy components and having a cloud point greater than 0° F., an ASTM D2887 end boiling point exceeding 650° F., and a pour point greater than 0° F., wherein at least 10 wt. % of the feed which boils over 650° F. is converted to lower boiling products, and an overall distillate yield of greater than 10 wt. % occurs, said distillate having a boiling range of about 330° F. to 730° F., the product having a pour point and a cloud point which has been reduced by at least 5° F. from that of the feedstock, said process comprising the following steps: (a) contacting said feedstock at superatmospheric hydrogen partial pressure with an isomerization dewaxing catalyst comprising ZSM-48 and a hydrogenation component, the hydrogenation component being Pt, Pd, or mixture thereof, to produce an isomerized product with a reduced wax content; and (b) contacting the isomerized product of step (a) with a distillate selective hydrocracking catalyst which comprises a noble metal hydrogenation component to upgrade said isomerized product with a reduced wax content to distillate.
