Abstract
A catalyst comprising a transition metal zeolite and a noble metal is disclosed. The catalyst is prepared by an extrusion method using a comb-branched polymer as an extrusion aid. The catalyst is used in a reaction to produce epoxide from an olefin, hydrogen, and oxygen. The comb-branched polymer improves the mechanical properties of the extrudate.
