Patent number: 7344694Abstract: A series of crystalline alumino-silicate zeolites identified as UZM-12 have been synthesized. These UZM-12 compositions have the ERI topology, a Si/Al>5.5 and can be prepared as nanocrystallites having an average particle size of about 15 to about 50 nanometers and a spheroidal morphology. The UZM-12 composition can be treated to remove at least a fraction of the framework aluminum atoms thereby providing zeolites with a Si/Al>5.75 and identified as UZM-12HS. Both the UZM-12 and UZM-12HS can catalyze various hydrocarbon conversion processes.Type: GrantFiled: October 6, 2004Date of Patent: March 18, 2008Assignee: UOP LLCInventors: Mark A.

Publication number: 20070224113Abstract: A process has been developed to synthesize various zeolites with nano size crystals. The process involves forming an aluminosilicate initiator which exhibits the Tyndall effect. This initiator is then mixed with a clear solution comprising reactive sources of Al, Si, M and R plus water. M is an alkali or alkaline earth metal while R is an organoammonium compound. The resultant reaction mixture is reacted at a temperature and for a time sufficient to produce a zeolite such as zeolite Y with average crystallite size less than 500 nm.Type: ApplicationFiled: March 20, 2007Publication date: September 27, 2007Inventors: Richard R. Willis, Dorothy E. Kuechl, Annabelle I. Benin
