DIRECT EPOXIDATION PROCESS AND EXTRUDED CATALYST THEREFOR

摘要

A catalyst comprising a transition metal zeolite and a noble metal is dis closed. The catalyst is prepared by an extrusion method using a comb-branche d 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 imp roves the mechanical properties of the extrudate.
