Using A Catalyst Having Two Different Zeolites For Transalkylation Of A C9+ Aromatic Feed

View page
US Patent:
7485763, Feb 3, 2009
Filed:
Nov 3, 2006
Appl. No.:
11/592832
Inventors:
John Scott Buchanan - Lambertville NJ, US
Ronald J. Cimini - Friendswood TX, US
Robert A. Crane - Lumberton TX, US
Wenyih F. Lai - Bridgewater NJ, US
Jose G. Santiesteban - Baton Rouge LA, US
David A. Stachelczyk - Houston TX, US
David L. Stern - Annandale NJ, US
Hye-Kyung C. Timken - Albany CA, US
William A. Weber - Burlington NJ, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
C07C 6/12
US Classification:
585475
Abstract:
In a process for converting C+ aromatic hydrocarbons to lighter aromatic products a feed comprising C+ aromatic hydrocarbons is contacted under transalkylation reaction conditions with a catalyst composition comprising (i) a first molecular sieve selected from the group consisting of ZSM-12, mordenite and a porous crystalline inorganic oxide material having an X-ray diffraction pattern including d-spacing maxima at 12. 40. 25, 6. 90. 15, 3. 570. 07 and 3. 420. 07; and (ii) a second molecular sieve having a constraint index ranging from 3 to 12. At least the first molecular sieve has a hydrogenation component associated therewith and the first and second molecular sieves are contained in the same catalyst bed. The C+ aromatic hydrocarbons are converted under the transalkylation reaction conditions to a reaction product containing xylene.

US Patent:
7553791, Jun 30, 2009
Filed:
Nov 5, 2004
Appl. No.:
10/982487
Inventors:
Timothy Edward McMinn - Houston TX, US
David Anthony Stachelczyk - Houston TX, US
Assignee:
ExxonMobil Chemical Patents Inc. - Houston TX
International Classification:
B01J 29/06
US Classification:
502 64, 502 60, 502 63, 502 74, 502 66, 502 77, 502 67, 502 69, 502 71
Abstract:
A catalyst composition, a process for producing the composition and a process for the conversion of a feedstock containing C+ aromatic hydrocarbons to produce a resulting product containing lighter aromatic products and less than about 0. 5 wt % of ethylbenzene based on the weight of Caromatics fraction of the resulting product. The C+ aromatic hydrocarbons are converted under the transalkylation reaction conditions to a reaction product containing xylene. The catalyst composition comprises (i) an acidity component having an alpha value of at least 300; and (ii) a hydrogenation component having hydrogenation activity of at least 300. The composition can be produced by to incorporating at least one hydrogenation component into an acidity component having an alpha value of at least 300.
