Patent number: 7713513Abstract: A family of crystalline aluminosilicate zeolites designated UZM-8HS and derived from UZM-8 have been synthesized. The aluminum content of the UZM-8HS is lower than that of the starting UZM-8 thus changing its ion exchange capacity and acidity. These UZM-8HS are represented by the empirical formula: M1an+Al(1?x)ExSiy?Oz? and are prepared by treatments such as acid extraction and AFS treatments.Type: GrantFiled: January 27, 2006Date of Patent: May 11, 2010Assignee: UOP LLCInventors: Deng-Yang Jan, Jaime G. Moscoso, Susan C. Koster, Lisa M. Knight, Gregory J. Lewis, Mark A. Miller, R. Lyle Patton, Stephen T. Wilson

Patent number: 7446071Abstract: A process is disclosed for enhancing the production of light olefins using a catalyst with small pores. The catalyst comprises a layered zeolite material comprising an inner layer having pores of 8 or 10 membered rings and an outer layer having pores of 10 membered rings. The pores in the outer layer overlaying the pores in the inner layer. The zeolite has a silicon to aluminum atomic ratio of about 20 to about 200 and its surface acid sites external to the pores have been substantially neutralized.Type: GrantFiled: November 17, 2004Date of Patent: November 4, 2008Assignee: UOP LLCInventors: Hayim Abrevaya, Suheil F.

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.

Patent number: 6890511Abstract: An aluminosilicate zeolite and substituted versions designated UZM-15 have been synthesized. These zeolites are prepared using an organoammonium cation as a template in which at least one organic group has at least 2 carbon atoms. An example of such a cation is diethyldimethylammonium cation. The template can optionally comprise other organoammonium cations, alkali metals and alkaline earth metals. These UZM-15 materials can be dealuminated by various processes to provide UZM-15HS compositions. Both the UZM-15 and UZM-15HS compositions are useful as catalysts or catalyst supports in various process such as the conversion of cyclic hydrocarbons to non-cyclic hydrocarbons and olefin oligomerization.Type: GrantFiled: March 21, 2003Date of Patent: May 10, 2005Assignee: UOP LLCInventors: Lisa M. Rohde, Gregory J. Lewis, Stephen T. Wilson, Deng-Yang Jan, R. Lyle Patton, Susan C. Koster, Jaime G. Moscoso, Mark A. Miller, Michael G. Gatter

Patent number: 5365008Abstract: An improved process is disclosed for the isomerization of butenes and/or pentenes using a catalyst comprising a silicoaluminophosphate molecular sieve containing noncondensed silica. It is of particular interest to increase the proportion of olefins containing tertiary carbons in the product with low formation of undesirable by-products.
