ABSTRACT:
A method for enhancing the activity of a porous crystalline zeolite having a framework silica-to-alumina mole ratio of 25 or more which comprises contacting the zeolite with a solution comprising a hydrate of trivalent metal fluoride in aqueous media under conditions sufficient to cause incorporation of said metal in the framework of said zeolite.
