ABSTRACT:
Dewaxing processes for hydrocarbon feedstocks are disclosed using novel catalysts comprising non-zeolitic molecular sieves, such as the silicoaluminophosphates of U.S. Pat. No. 4,440,871. The products of the instant dewaxing processes are characterized by lower pour points than the hydrocarbon feedstock.
