Abstract
A catalyst comprising a transition metal zeolite, a noble metal, and a thiol is disclosed. The catalyst is used in an epoxidation process comprising reacting an olefin, hydrogen, and oxygen. The presence of a thiol in the catalyst reduces the formation of alkanes from the hydrogenation of olefins, and/or improves hydrogen and oxygen selectivities to epoxides.
