ABSTRACT:
A diesel or jet fuel distillate product is recovered from a hydrocracking process in an integrated flowscheme wherein the distillate is removed from the hydrocracking zone product column and then passed into a catalytic dewaxing zone. The once-through hydrogen provided in the catalytic dewaxing zone is the makeup hydrogen for the hydrocracking zone. Large economies are realized in terms or reduced capital costs compared to the conventional flowscheme. In addition the severity of the hydrocracking operation is reduced thus extending the life of the hydrocracking catalyst.
