Abstract
A catalyst comprising a transition metal zeolite and a supported noble metal is disclosed. The mean mass diameter of the catalyst is greater than 0.5 mm. The catalyst is formed from transition metal zeolite particles and the supported noble metal particles each having a mean mass diameter of less than 0.1 mm. An epoxidation process by reacting an olefin, hydrogen, and oxygen in the presence of the catalyst is disclosed.
