Abstract
A catalyst comprising a spray-dried transition metal zeolite and a noble metal is disclosed. The spray-dried transition metal zeolite comprises a transition metal zeolite and a binder. At least 50 wt. % of the binder is titania. The catalyst is used in a process to produce an epoxide by reacting an olefin, hydrogen, and oxygen. The catalyst is easy to filter from a slurry and produces a reduced level of hydrogenation products.
