Process for catalytic dewaxing with mordenite

Patent ·
OSTI ID:5622111
The method of catalytically dewaxing a hydrocarbon base lubricating oil, charge containing a wax fraction, is described consists of: passing a hydrocarbon base lubricating oil charge, at anhydrous dewaxing catalytic conditions, into contact with a dewaxing catalyst, a hydrogen mordenite catalyst, which catalyst has been calcined at 1300/sup 0/F-1500/sup 0/F after contact with water for the last time, having a silica-to-alumina mole ratio of 10:50:1, loaded with a metal of the platinum-palladium group, the catalyst containing activated sites, thereby forming a product dewaxed lubricating oil base stock; and recovering the product.
