Method Of Protecting Sapo Molecular Sieve From Loss Of Catalytic Activity

View page
US Patent:
6897179, May 24, 2005
Filed:
Jun 13, 2003
Appl. No.:
10/461621
Inventors:
Shun Chong Fung - Bridgewater NJ, US
Stephen Neil Vaughn - Kingwood TX, US
Marcel Johannes Janssen - Kessel-Lo, BE
Luc Roger Marc Martens - Meise, BE
Kenneth Ray Clem - Humble TX, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
B01J027/18
B01J027/182
US Classification:
502208, 502214
Abstract:
Disclosed is a method of protecting the loss of catalytic activity of metalloaluminophosphate molecular sieve, particularly a SAPO molecular sieve, from contact with moisture. The method involves heating the metalloaluminophosphate molecular sieve so as to remove template, and provide a molecular sieve in sufficiently dry form for storage.

US Patent:
7033971, Apr 25, 2006
Filed:
Feb 9, 2004
Appl. No.:
10/774859
Inventors:
Shun C. Fung - Bridgewater NJ, US
Richard B. Hall - Whitehouse Station NJ, US
Hafedh Kochkar - Phillipsburg NJ, US
Karl G. Strohmaier - Port Murray NJ, US
Nicolas P. Coute - Houston TX, US
Kenneth R. Clem - Humble TX, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
B01J 27/182
B01J 21/20
US Classification:
502214, 502 20, 502208
Abstract:
A method for maintaining the activity of silicoaluminophosphate (SAPO) molecular sieve catalyst particles during oxygenate to olefin conversion reactions. After regeneration of SAPO catalyst particles, the regenerated particles are mixed with particles having coke on their surface in a manner that maintains their catalytic activity at a predetermined level.

Regeneration Of Severely Deactivated Reforming Catalysts

View page
US Patent:
57768498, Jul 7, 1998
Filed:
Sep 9, 1992
Appl. No.:
7/942694
Inventors:
Shun Chong Fung - Bridgewater NJ
John Francis Walsh - Houston TX
Gary Brice McVicker - Califon NJ
Kenneth Ray Clem - Humble TX
Assignee:
Exxon Research & Engineering Company - Florham Park NJ
International Classification:
B01J 2938
B01J 3844
B01J 3842
C10G 35095
US Classification:
502 37
Abstract:
The invention is directed a process for regenerating deactivated reforming catalysts comprising at least one Group VIII metal on zeolite L, preferably wherein the catalysts are extruded using a binder material such as alumina or silica. The process includes: a) coke burn at severe conditions to improve the accessibility of the Group VIII catalytic metal particles by transporting them to the outside of the zeolite microchannels; b) catalytic metal redispersion by wet oxychlorination with elemental chlorine and oxygen; c) stripping with a gas stream comprising oxygen and water at low pressure to remove as much residual chlorine as possible; and d) reduction of catalytic metals with hydrogen at low pressure. The process is particularly effective for recovering activity of catalysts which have been severely deactivated.

Fixed-Bed/Moving-Bed Two Stage Catalytic Reforming With Interstage Aromatics Removal

View page
US Patent:
52118380, May 18, 1993
Filed:
Dec 9, 1991
Appl. No.:
7/805334
Inventors:
Stuart S. Goldstein - Ewell, GB2
Paul W. Kamienski - Basking Ridge NJ
Gerrit S. Swart - Westfield NJ
George A. Swan - Baton Rouge LA
Kenneth R. Clem - Humble TX
Assignee:
Exxon Research & Engineering Company - Florham Park NJ
International Classification:
C10G 3504
US Classification:
208 65
Abstract:
A two stage process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock. The reforming is conducted in two stages wherein the first stage is operated in a fixed bed mode, and the second stage is operated in a moving bed continual catalyst regeneration mode. A gaseous stream comprised of hydrogen and predominantly C. sub. 4. sup. - and a C. sub. 5. sup. + liquid stream are produced between stages. A portion of the hydrogen-rich stream is recycled and the and the remaining portion and an aromatics-lean stream, which is obtained during aromatics separation between stages, is sent to second stage reforming.
