TWO-STAGE HYDROCARBON DEWAXING HYDROTREATING PROCESS ABSTRACT The pour point of a hydrocarbon charge stock boiling in the range of 204° to 566°C (400°F to 1050°F), and particularly a lubricating oil charge stock boiling from 316° to 566°C (600°F to 1050°F) is reduced by catalytically dewaxing the charge stock in the presence of a zeolite catalyst and subsequently subjecting at least the liquid portion thereof to hydrotreating in the presence of a hydrotreating catalyst comprising a hydrogenating component and a siliceous porous crystalline material selected from ZSM-5, ZSM-11, ZSM-23 and ZSM-35 zeolites.
