Zusammenfassung:Described is a method of improving the process and operation of an existing system for manufacturing ethylene oxide. The ethylene oxide manufacturing system includes an epoxidation reactor system containing a volume of high activity epoxidation catalyst. The method includes replacing a portion of the volume of high activity epoxidation catalyst with a volume of high selectivity catalyst, and modifying the operation of the process system so as to provide for a feed to the epoxidation reactor system having a reduced carbon dioxide concentration.
