Abstract:
1. A method for producing a a diesel fuel, and lubricant basestock, comprising: contacting a hydrotreated feedstock and a hydrogen containing gas with a hydrocracking catalyst under effective hydrocracking conditions to produce a hydrocracked effluent, wherein the hydrotreated feedstock is a vacuum gas oil, cascading the entire hydrocracked effluent, without separation, to a catalytic dewaxing stage, and dewaxing the entire hydrocracked effluent under effective catalytic dewaxing conditions, wherein the combined total sulfur in liquid and gaseous forms fed to the dewaxing stage is greater than 1000 ppm by weight of sulfur on the hydrotreated feedstock basis, wherein the hydrocracking catalyst includes a zeolite Y based catalyst, and wherein the dewaxing catalyst includes at least one unidimensional, 10-member ring pore zeolite, at least one Group VIII metal, and at least one low surface area, metal oxide, refractory binder, and wherein the dewaxing catalyst comprises a micropore surface area to total surface area of greater than or equal to 25%, wherein the total surface area equals the surface area of the external zeolite plus the surface area of the binder.
