US Patent:

6383966, May 7, 2002

Filed:

Jun 9, 2000

Appl. No.:

09/591600

Inventors:

Yuan-Zhang Han - West Chester PA
Edrick Morales - West Chester PA
Robert G. Gastinger - West Chester PA
Kevin M. Carroll - Havertown PA

Assignee:

Arco Chemical Technology, L.P. - Greenville DE

International Classification:

B01J 29104

US Classification:

502 63, 502350, 502 64, 502 85

Abstract:

Highly active and selective epoxidation catalysts are prepared by combining highsurface area silica support or the like, having surface area greater than 1100 m /g, with a titanium source. The titanium source is a non-oxygenated hydrocarbon solution of a titanium halide or a vapor stream of titanium tetrachloride. The impregnated support is then calcined at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacted with water and/or silylated. The resulting materials are highly active heterogeneous epoxidation catalysts for the reaction of olefins with organic hydroperoxides.

Appl. No.:

10/251141

Inventors:

Yuan-Zhang Han - West Chester PA, US

International Classification:

B01J020/34
B01J038/12
B01J038/42

US Classification:

502 38, 502 35, 502 56

Abstract:

Used titanium-containing silicon oxide catalysts are regenerated by heating the used catalyst at a temperature of at least 400 C. in the presence of a oxygen-containing gas stream, followed by impregnation with a titanium source, and then calcining the impregnated catalyst to form a reactivated catalyst.

International Classification:

C10G029/20

US Classification:

208/196000, 208/20800R

Abstract:

This invention is a method of oxidizing organosulfur impurites found in fuel streams. The method comprises reacting the organosulfur impurities with an organic hydroperoxide in the presence of a titanium-containing catalyst. The titanium-containing catalyst is obtained by impregnating a siliceous solid with a titanium halide in a hydrocarbon solvent, or a vapor stream of titanium tetrachloride, followed by calcination. The resulting sulfones are more readily removed from the fuel stream than the non-oxidized organosulfur impurities.

International Classification:

C07D30119

US Classification:

549529

Abstract:

Highly active and selective epoxidation catalysts are prepared by combining high surface area silica support or the like, having surface area greater than 1100 m. sup. 2 /g, with a titanium source. The titanium source is a non-oxygenated hydrocarbon solution of a titanium halide or a vapor stream of titanium tetrachloride. The impregnated support it then calcined at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacted with water and/or silylated. The resulting materials are highly active heterogeneous epoxidation catalysts for the reaction of olefins to with organic hydroperoxides.

International Classification:

C07D30119

US Classification:

549529

Abstract:

Highly active and selective epoxidation catalysts are prepared by combining silica or the like with a non-oxygenated hydrocarbon solution of titanium halide, removing solvent, calcining at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacting with water and silylating. The resulting materials are useful heterogeneous catalysts for transforming olefins to epoxides using organic hydroperoxides.
