US Patent:

53244168, Jun 28, 1994

Filed:

Jun 27, 1991

Appl. No.:

7/722048

Inventors:

William E. Cormier - Ellicott City MD
Gerald M. Woltermann - Westminster MD
John S. Magee - Ellicott City MD
Fred J. Baars - Leiden, NL
Lawrence L. Upson - Barrington IL

Assignee:

W. R. Grace Co.-Conn. - New York NY

International Classification:

C10G 1102

US Classification:

208113

Abstract:

An FCC catalyst system and a process using the catalyst system are disclosed. The catalyst system comprises a metal trap component, such as bastnaesite or barium titanate, and a sulfur oxide acceptor such as a magnesium spinel in addition to a zeolite. The metal trap and sulfur oxide components are preferably in separate particles. The catalyst formulation results in improved activity believed to result from the sulfur oxide acceptor protecting the metal trap component from the harmful effects of sulfur oxides such as the formation of stable metal oxides.

Filed:

Oct 1, 1979

Appl. No.:

6/080959

Inventors:

David E. W. Vaughan - Columbia MD
Roger J. Lussier - Ellicott City MD
John S. Magee - Ellicott City MD

Assignee:

W. R. Grace & Co. - New York NY

International Classification:

B01J 2116

US Classification:

252455R

Abstract:

Pillared interlayered clays are reacted with a base such as ammonium hydroxide to increase the ion exchange capacity thereof. The pillared interlayered clays are prepared by reacting a smectite clay, such as bentonite, with a metal complex polymer, such as chlorhydrol, and calcining the resulting product.

International Classification:

B01J 3702
B01J 2906

US Classification:

252453

Abstract:

An amorphous hydrocarbon cracking catalyst of high activity is prepared by mixing solutions of sodium silicate and sodium aluminate, allowing the gel and age, acidulating said gel to precipitate the excess aluminate and ion exchanging after drying to accomplish removal of the alkali metal.

Inventors:

David E. W. Vaughan - Columbia MD
Roger J. Lussier - Ellicott City MD
John S. Magee - Ellicott City MD

Assignee:

W. R. Grace & Co. - New York NY

International Classification:

B01J 2906

US Classification:

252455Z

Abstract:

Stable pillared interlayered clay compositions are prepared by reacting smectite type clays with polymeric cationic hydroxy metal complexes of metals such as aluminum, zirconium, and/or titanium. These novel interlayered clay compositions which possess substantial surface area in pores of less than 30 A in diameter are used as catalysts, catalytic supports, and sorbents.

Appl. No.:

5/609318

International Classification:

C10G 1104
B01J 2912

US Classification:

208120

Abstract:

Uranium oxide or uranium and silver oxides in combination with hydrogen or rare earth oxides are exchanged into zeolites as components of zeolite cracking catalysts to increase the olefin content of the gasoline and, thus, enhance the yield of high octane components as well as reduce the coking tendency of the catalyst.

Appl. No.:

5/639850

Inventors:

John E. Magee - Ardsley NY

International Classification:

B66B 116

US Classification:

187 29R

Abstract:

An elevator control modifying system which detects the existence of a call registered by a passenger in an elevator car and, until delivery of the registering passenger to the call destination, automatically prevents stopping of the elevator for calls registered at intervening landings and to which the car would normally respond. Upon delivery of the car passenger at the designated floor, the control is automatically conditioned to respond to calls registered at landings. Optionally, high call reversal, if present, is restricted to effective car calls when such a call is registered by the car passenger.

Appl. No.:

5/463611

Assignee:

W. R. Grace & Co. - New York NY

International Classification:

B01J 2912
C10G 1102

US Classification:

208120

Abstract:

A stable rare earth exchanged zeolite having high catalytic activity and improved coke selectivity is prepared by a series of exchange steps whereby the rare earth is introduced into the zeolite in a multi-step e. g. , two step manner. The method comprises exchanging a sodium zeolite to less than 4. 0 weight percent Na. sub. 2 O, exchanging with rare earth to give an initial rare earth oxide content of 0. 3 to 5 weight percent, calcining, and further rare earth exchanging the zeolite to give a final rare earth content of 1. 0 to 10 weight percent.
