Process for preparing ethene oxide

摘要

A process for preparing ethene oxide comprising providing a liquid feed stream comprising ethene, hydrogen peroxide, and a solvent; passing the liquid feed stream into an epoxidation zone comprising a catalyst comprising a titanium zeolite comprising zinc and having framework type MWW, and subjecting the liquid feed stream to epoxidation reaction conditions in the epoxidation zone, obtaining a reaction mixture comprising ethene oxide, water, and the solvent; removing an effluent stream from the epoxidation zone, the effluent stream comprising ethene oxide, water and the solvent.
