US Patent:

56367473, Jun 10, 1997

Filed:

Sep 13, 1994

Appl. No.:

8/305525

Inventors:

William P. Hettinger - Deerfield Beach FL
Howard F. Moore - Catlettsburg KY
Terry L. Goolsby - Ashland KY
A. V. Peppard - Catlettsburg KY

Assignee:

Ashland Inc. - Ashland KY

International Classification:

B03C 100

US Classification:

209213

Abstract:

Optimized utilization of combinations of fluid catalyst magnetic separator, classifier, and/or attriter can be used to achieve lower catalyst cost, and better catalyst activity and selectivity through control of metal-on-catalyst, particle size and particle size distribution. This process is especially useful when processing high metal-containing feedstocks. This provides a catalyst recovery unit (RCU. TM. ) ancillary to an FCC or similar unit.

Appl. No.:

8/804856

Assignee:

Marathon Ashland Petroleum LLC

International Classification:

C10G 900
C10G 2904
C10B 5500
B01J 2390

US Classification:

208106

Abstract:

Magnetic separation of fluid cracking catalyst and magnetic hooks can be improved by adding antimony, in the feed or during catalyst manufacture, to enhance the magnetic susceptibility, thus increasing the separation efficiency of the older less active fluid cracking catalyst from the more desirable fraction for recycle. Antimony can also be used as a tag for determination of age distribution of said catalyst. Concentration levels of 0. 005-15 wt. % antimony (Sb) on the catalyst or sorbent are preferred. The invention is particularly preferred on catalyst and sorbents which comprise at least about 0. 001 wt. %, more preferably above about 0. 01 wt. % iron, because the antimony has been found to enhance the magnetic susceptibility of iron-containing particulates.

Appl. No.:

9/425811

Inventors:

Terry L. Goolsby - Ashland KY
Maurice M. Mitchell - Ashland KY

Assignee:

Marathon Ashland Petroleum, LLC - Findlay OH

International Classification:

B01J 2904
B01J 2987
B01J 2906
B01J 2100
B01J 2900

US Classification:

502 60

Abstract:

A catalytic cracking catalyst comprising zeolite, kaolin, alumina and/or silica, antimony and 100-5,000 wt. ppm Ni is disclosed. The Ni-antimony interact in the environment of a fluidized catalytic cracking reactor to increase the magnetic susceptibility of the catalyst, permitting removal of nickel contaminated catalyst by magnetic separation.
