Zeolite-Containing Oxidation Catalyst And Method Of Use

View page
US Patent:
2001003, Nov 8, 2001
Filed:
Jun 13, 2001
Appl. No.:
09/880375
Inventors:
Bulent Yavuz - Plainfield NJ,
Kenneth Voss - Somerville NJ,
Michel Deeba - North Brunswick NJ,
John Adomaitis - Old Bridge NJ,
Robert Farrauto - Westfield NJ,
International Classification:
B01J029/06
B01J023/10
US Classification:
423/213200, 502/060000, 502/064000, 502/066000, 502/074000
Abstract:
Oxidation catalyst compositions for treating diesel exhaust include ceria and, optionally, alumina, each having a surface area of at least about 10 m/g, and a zeolite, e.g., Beta zeolite. Optionally, platinum may be included in the catalytic material, preferably in amounts which are sufficient to promote some gas-phase oxidation of carbon monoxide (“CO”) and hydrocarbons (“HC”) but which are limited to preclude excessive oxidation of SOto SO. Alternatively, palladium in any desired amount may be included in the catalytic material. The zeolite is optionally doped, e.g., ion-exchanged, with one or more of hydrogen, a platinum group metal or other catalytic metals. The catalyst compositions may be used in a method to treat diesel engine exhaust by contacting the hot exhaust with the catalyst composition to promote the oxidation of gas-phase CO and HC and of the volatile organic fraction component of particulates in the exhaust.

US Patent:
5340516, Aug 23, 1994
Filed:
Jul 16, 1993
Appl. No.:
8/093104
Inventors:
Bulent O. Yavuz - Plainfield NJ
Matthew P. Larkin - Phillipsburg NJ
Gary W. Rice - Scotch Plains NJ
Kenneth E. Voss - Somerville NJ
Assignee:
Engelhard Corporation - Iselin NJ
International Classification:
B32B 312
C04B 3510
US Classification:
264 63
Abstract:
Particles of an interconnected three-dimensional network of bar-like topaz crystals are used as a reactant (with added silicon dioxide, or a mixture with added silicon dioxide and hydrated aluminum fluoride or added silicon dioxide, hydrated aluminum fluoride and alumina) to form mullite whisker honeycomb articles suitable as catalyst supports.

Oxidation Catalyst With Bulk Ceria, A Second Bulk Metal Oxide, And Platinum

View page
US Patent:
5491120, Feb 13, 1996
Filed:
May 23, 1994
Appl. No.:
8/247531
Inventors:
Kenneth E. Voss - Somerville NJ
Bulent O. Yavuz - Plainfield NJ
Robert J. Farrauto - Westfield NJ
Michael P. Galligan - Clark NJ
Assignee:
Engelhard Corporation - Iselin NJ
International Classification:
B01J 2363
B01J 2342
B01J 2106
B01J 2104
US Classification:
502304
Abstract:
Oxidation catalyst compositions include a catalytic material having a BET surface area of at least about 10 m. sup. 2 /g and consisting essentially of a combination of bulk ceria and a bulk second metal oxide which may be one or more of titania, zirconia, ceria-zirconia, silica, alumina-silica and. alpha. -alumina. The combination may optionally also include activated alumina having a BET surface area of at least about 10 m. sup. 2 /g. The ceria, second metal oxide and optional activated alumina may be mixed together or provided as discrete layers. Optionally, one of platinum or palladium metal may be dispersed on the catalytic material provided that the platinum, when used, is used in limited amounts to preclude excessive oxidation of SO. sub. 2 to SO. sub. 3. The catalyst compositions may be used for oxidation of oxidizeable components in a gas-borne stream, e. g. , in a method to treat diesel engine exhaust by contacting the hot exhaust with the catalyst composition to promote the oxidation of the volatile organic fraction.
