Abstract
An integrated distillate hydrocracking process produces one or more fuel products and one or more lube products from a first reaction stage. Heavy fractions from the first stage, which are not recovered as lube products, are cracked to fuels in a second reaction stage. This invention is intended to provide a full range of lube streams, over a wide viscosity range and a wide viscosity index range, from a fuels hydrocracker, in addition to high yields of high quality fuels.
