Two-stage hydrocarbon dewaxing hydrotreating process

Patent ·
OSTI ID:6641823
The pour point of a hydrocarbon charge stock boiling in the range of 400/sup 0/ F. to 1050/sup 0/ F., and particularly a lubricating oil charge stock boiling between 600/sup 0/ F. and 1050/sup 0/ 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 from the class of ZSM-5, ZSM-11, ZSM-23 and ZSM-35 zeolites.
