Abstract:
Crystalline microporous zeolites designated calcined UZM-22 and UZM-22HS have been synthesized. The calcined UZM-22 is represented by the empirical formula: M1′mn+Al1-xExSiyOz and UZM-22HS has an empirical formula of: M1an+Al(1-x)ExSiy′Oz″ where M1 and M1′ are exchangeable cations such as lithium or strontium and E is a framework element such as gallium. Both zeolites are obtained from an as synthesized microporous crystalline composition having an empirical formula of: Mmn+RrAl1-xExSiyOz either by calcination for UZM-22 or by various treatments such as ammonium hexafluorosilicate treatment for UZM-22HS.M is an alkali, alkaline earth, or rare earth metal such as lithium and strontium, R is a singly charged organoammonium cation such as the choline cation and E is a framework element such as gallium.
