Patent number: 7977273Abstract: A catalyst for converting methanol to light olefins and the process for making and using the catalyst are disclosed and claimed. SAPO-34 is a specific catalyst that benefits from its preparation in accordance with this invention. A seed material is used in making the catalyst that has a higher content of the EL metal than is found in the principal part of the catalyst. The molecular sieve has predominantly a roughly rectangular parallelepiped morphology crystal structure with a lower fault density and a better selectivity for light olefins.Type: GrantFiled: April 28, 2009Date of Patent: July 12, 2011Assignee: UOP LLCInventors: Wharton Sinkler, Robert W. Broach, Natasha Erdman, Thomas M. Reynolds, John Q. Chen, Stephen T. Wilson, Paul T. Barger

Publication number: 20100081851Abstract: This invention involves the use of a more effective adsorbent to dehydrate ethanol. The most common use for the ethanol is an additive to gasoline. The preferred adsorbent is a type 3A adsorbent that has been ion exchanged with potassium at a level of about 0.6. Surprisingly, this adsorbent has a significantly improved resistance to damage by water upset events.Type: ApplicationFiled: September 10, 2009Publication date: April 1, 2010Applicant: UOP LLCInventors: Alan P.

Patent number: 6207872Abstract: A catalyst for converting methanol to light olefins along with the process itself are disclosed and claimed. The catalyst is a metalloaluminophosphate molecular sieve having the empirical formula (ELxAlyPz)O2 where EL is a metal such as silicon or magnesium and x, y and z are the mole fractions of EL, Al and P respectively. The molecular sieve has predominantly a plate crystal morphology in which the average smallest crystal dimension is at least 0.1 microns and has an aspect ratio of no greater than 5. Use of this catalyst gives a product with a larger amount of ethylene versus propylene.Type: GrantFiled: May 6, 1999Date of Patent: March 27, 2001Assignee: UOP LLCInventors: Paul T. Barger, Stephen T. Wilson, Thomas M. Reynolds

Patent number: 5516957Abstract: This invention presents a novel MgAPSO molecular sieve, containing a critical range of magnesium in the sieve framework and having a small crystallite size, which is particularly active for hydrocarbon conversion. The sieve advantageously is incorporated, along with a platinum-group metal, into a catalyst formulation which is useful for isomerization. When utilized in a process for isomerizing a non-equilibrium mixture of xylenes containing ethylbenzene, a greater yield of para-xylene is obtained compared to prior-art processes.Type: GrantFiled: May 17, 1995Date of Patent: May 14, 1996Assignee: UOPInventors: Hermant W. Dandekar, David A. Lesch, Thomas M. Reynolds, Robert L. Patton, Stephen T. Wilson, Gregory J. Gajda
