Abstract
Methods are provided for processing a gas oil boiling range feedstock, such as a vacuum gas oil, in a single reaction stage and/or without performing intermediate separations. The methods are suitable for forming lubricants and distillate fuels while reducing or minimizing the production of lower boiling products such as naphtha and light ends. The methods can provide desirable yields of distillate fuels and lubricant base oils without requiring separate catalyst beds or stages for dewaxing and hydrocracking. The methods are based in part on use of a dewaxing catalyst that is tolerant of sour processing environments while still providing desirable levels of activity for both feed conversion and feed isomerization.
