A method of manufacturing ethylene oxide by contacting an epoxidation reactor feed that can comprise ethylene, oxygen, and a concentration of carbon dioxide with a high selectivity epoxidation catalyst. The contacting of the epoxidation reactor feed is conducted under epoxidation reaction conditions so that the performance of the high selectivity epoxidation catalyst is enhanced. A low carbon dioxide concentration in the epoxidation reactor feed contributes to the enhancement of the catalytic performance of the high selectivity epoxidation catalyst by, for example, improving catalyst stability, selectivity and activity. |
