Filed:

Mar 16, 1987

Appl. No.:

7/026234

Inventors:

Richard E. Lowery - Tulsa OK
Denton C. Fentress - Pawhuska OK
Don W. Godbehere - Ochelata OK

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

B01F 312
B01J 1300
C01G 3000
F26B 312

US Classification:

2523635

Abstract:

A process is disclosed for producing a powdered antimony pentoxide composition that rapidly disperses on contact with water. The process comprises spray drying the antimony sol at a temperature of from 180. degree. to 210. degree. F.

Appl. No.:

7/420790

Richard E. Lowery - Tulsa OK
Chia M. Fu - Bartlesville OK
Michael K. Maholland - Bartlesville OK

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C10G 1105

US Classification:

208120

Abstract:

A process for reactivating a spent, metal-contaminated zeolite-containing catalytic cracking catalyst composition comprises contacting the spent catalyst composition with an acidified aqueous NH. sub. 4 NO. sub. 3 solution, thereafter with a suitable fluorine compound (preferably dissolved NH. sub. 4 F), and, optionally, additionally with an antimony compound. The thus prepared reactivated cracking catalyst composition is used in a process for catalytically cracking a liquid hydrocarbon-containing feed.

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C10G 1105
B01J 3866

US Classification:

208120

Abstract:

A process for reactivating a spent, metal-contaminated zeolite-containing cracking catalyst composition comprises the substantially simultaneous contacting with a fluorine compound (preferably HH. sub. 4 F) and a metals passivating agent (preferably a compound of Sb or Ca). The thus reactivated cracking catalyst composition is employed in a catalytic cracking process.

International Classification:

B01J 2938
B01J 3866
B01J 3854
C10G 1105

US Classification:

502 26

Abstract:

A process for reactivating a spent, metal-contaminated zeolite-containing catalytic cracking catalyst composition comprises partially demetallizing (preferably by chlorinating and washing) the spent catalytic cracking catalyst composition, and thereafter contacting it with at least one fluorine compound (preferably NH. sub. 4 F) and at least one antimony compound. The thus reactivated catalytic cracking catalyst composition is employed in a catalytic cracking process.
