ABSTRACT:
A method is disclosed for increasing the hydrocarbon sorption capacity of a highly siliceous shape-selective zeolite by exposing the zeolite to an aqueous solution having an initial pH ranging between about 10.5 to about 14. The method is particularly useful for treating steam deactivated zeolites.
