Abstract
Catalyst composition comprising titanium chemically bonded to a silica support, characterised in that the silica support is a shaped extrudate of silica powder. The catalyst composition is very useful in the epoxidation of olefins into alkylene oxides using organic hydroperoxides. The composition can be prepared by a process comprising the steps of: (a) extruding silica powder into an extrudate having a selected shape; (b) calcining the extrudate; (c) impregnating the extrudate with a titanium-containing impregnating agent; and (d) drying and calcining the impregnated extrudate.
