Abstract
Applicants have synthesized a new crystalline aluminosilicate zeolite identified as UZM-4M. This new zeolite is obtained by treating a UZM-4 zeolite with a fluorosilicate salt to obtain a zeolite having the empirical formula:M1an+Al1-xExSiyOz where M1 is an alkali metal, alkaline earth metal, rare earth metal, hydronium ion or ammonium ion, E can be gallium, iron, boron, indium and mixtures thereof and has a Si/Al ratio of 1.5 to about 10.
