Filed:

Sep 10, 1981

Appl. No.:

6/300886

Inventors:

Ajay M. Madgavkar - Irvine CA
Harold E. Swift - Pittsburgh PA

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

B01D 5336
C01B 1704

US Classification:

423224

Abstract:

US Patent:

43780482, Mar 29, 1983

Filed:

May 8, 1981

Appl. No.:

6/261746

Inventors:

Ajay M. Madgavkar - Irvine CA
Harold E. Swift - Gibsonia PA

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

F21B 4324

US Classification:

166256

Abstract:

Low heating value gases are combusted substoichiometrically in two combustion zones in series in contact with two different supported platinum catalysts in which the concentration of platinum in the catalyst in the first zone is higher than the concentration of platinum in the second catalyst. The combusted gas of reduced carbon monoxide can be directly vented to the atmosphere after energy has been extruded from it for a useful purpose.

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

C07C 712
C07C 318

US Classification:

585823

Abstract:

Boron trifluoride is removed from coordination compounds contaminating organic liquids by contacting the contaminated liquid with silica. For example, boron trifluoride is removed from a boron trifluoride-n-butanol coordination compound contaminating a 1-olefin oligomer product by passing the contaminated liquid oligomer through a bed of silica.

US Patent:

43942962, Jul 19, 1983

Filed:

Aug 3, 1981

Appl. No.:

6/289456

Inventors:

Ajay M. Madgavkar - Irvine CA
Harold E. Swift - Gibsonia PA

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

B01J 2102
B01J 3700

US Classification:

252433

Abstract:

A three-component catalyst is prepared comprising a particulate silica adsorbent with boron trifluoride and water adsorbed on the silica. The silica-water-boron trifluoride catalyst is used in hydrocarbon conversion reactions such as the oligomerization of 1-decene to a product predominating in the trimer and tetramer.

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

C07C 712
C10G 1700

US Classification:

585830

Abstract:

Boron trifluoride contaminant is removed from organic liquids by contacting the contaminated liquid with polyvinyl alcohol. For example, boron trifluoride catalyst is removed from 1-olefin oligomer product by passing the liquid oligomer through a bed of granular polyvinyl alcohol.

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

C07C 712
C07C 318

US Classification:

585525

Abstract:

Spent boron trifluoride catalyst is removed from organic liquids by contacting the liquid with polyvinyl alcohol. For example, boron trifluoride catalyst is removed from 1-olefin oligomer product by passing the liquid oligomer through a bed of granular polyvinyl alcohol. The boron trifluoride is recovered from the polyvinyl alcohol and is recycled for use as a catalyst.

US Patent:

Filed:

Feb 25, 1981

Appl. No.:

6/238032

Inventors:

Ajay M. Madgavkar - Irvine CA
Roger F. Vogel - Butler PA
Harold E. Swift - Gibsonia PA

Assignee:

Gulf Research & Development Company - Pittsburgh PA

International Classification:

F02C 322

US Classification:

60 3906

Abstract:

The combustible component of a stream of low heating value gas comprising carbon monoxide, hydrogen and methane is combusted using less than a stoichiometric amount of air in the presence of an oxygenation catalyst and the heat energy in the combusted gas is utilized, for example, by expansion in a gas turbine.
