Patent 7981273 was granted and assigned to Honeywell UOP on July, 2011 by the United States Patent and Trademark Office.
Catalytic cracking processes such as fluidized catalytic cracking, naphtha cracking, and olefin cracking are catalyzed by the UZM-35 family of crystalline aluminosilicate zeolites represented by the empirical formula:Mmn+Rr+Al(1-x)ExSiyOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the dimethyldipropylammonium cation and E is a framework element such as gallium. These UZM-35 zeolites are active and selective in the catalytic cracking of hydrocarbons.
