摘要： A catalyst composition comprising titanium incorporated into a silica support, characterized in that the silica support is a shaped extrudate of silica powder. The catalyst composition is useful in the epoxidation of olefins into alkylene oxides using organic hydroperoxides. The composition can be prepared by extruding silica powder into an extrudate having a selected shape; calcining the extrudate; impregnating the extrudate with a titanium-containing impregnating agent; and drying and calcining the impregnated extrudate.

摘要： The present invention provides a catalyst system that may be used to regenerate NOx adsorber catalysts. It also provides methods for using these catalysts. According to the present invention, hydrocarbons are introduced into an exhaust gas stream upstream of a metal ion exchanged zeolite catalyst to generate CO. The metal ion exchanged zeolite catalyst is preferably a Cu-ZSM-5 catalyst that has a high loading of copper. The hydrocarbons are oxidized to carbon monoxide, and the carbon monoxide is then exposed to a NOx adsorber catalyst, which facilitates regeneration of that catalyst.
