    Abstract: A process for catalytically dewaxing an oil which comprises contacting the oil at a temperature between 500* and 900* F., a pressure between 300 and 5,000 p.s.i.g., and in the presence of hydrogen, with a catalyst comprising a mixture of mordenite and an amorphous porous inorganic oxide associated with nickel and tin. Preferably the mixture of mordenite and the nickel-tin component is a physical mixture, i.e., preferably the nickel and tin are not supported on the mordenite, as by impregnation or ion-exchange into the mordenite. Preferably, the amorphous porous inorganic oxide associated with the nickel and tin is silica.
