Abstract
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.
