摘要：A method for the start-up of a process for the epoxidation of ethylene comprising: initiating an epoxidation reaction by reacting a feed gas composition containing ethylene, and oxygen, in the presence of an epoxidation catalyst at a temperature of about 180° C. to about 210° C.; adding to the feed gas composition about 0.05 ppm to about 2 ppm of moderator; increasing the first temperature to a second temperature of about 240° C. to about 250° C., over a time period of about 12 hours to about 60 hours; and maintaining the second temperature for a time period of about 50 hours to about 150 hours.
