US Patent:

7452846, Nov 18, 2008

Filed:

May 22, 2007

Appl. No.:

11/751996

Inventors:

Bobby G. Cockrell - Bartlesville OK, US
Glenn W. Dodwell - Bartlesville OK, US
Brent J. Bertus - Bartlesville OK, US

Assignee:

China Petroleum & Chemical Corporation - Beijing

International Classification:

B01J 29/06
B01J 20/00

US Classification:

502407, 502 64, 502 66, 502 71

Abstract:

A desulfurization system employing a system of fluidizable and circulatable solid particles to desulfurize a hydrocarbon-containing fluid in a fluidized bed reactor. The solid particulate system includes solid sorbent particles operable to remove sulfur from the hydrocarbon-containing fluid stream and solid catalyst particles operable to enhance the octane of the resulting desulfurized hydrocarbon-containing fluid stream. The solid particulate system can be circulated between a reactor, regenerator, and reducer, to thereby allow for substantially continuous desulfurization in the reactor.

Appl. No.:

10/170953

International Classification:

B01D053/60

US Classification:

502/414000, 423/244020

Abstract:

The attrition resistance of sorbent compositions are enhanced by controlling the pH of the support mixture containing the initial ingredients of the sorbent support. Desulfurization of a sulfur-containing fluid, such as cracked gasoline or diesel fuel, is enhanced by employing a co-feed gas comprising from about 80 to about 97 volume percent hydrogen.
