    摘要： The present disclosure provides processes for the start-up of an ethylene epoxidation process comprising: a. contacting a high selectivity epoxidation catalyst with a feed comprising ethylene, oxygen and an organic chloride for a period of time such that vinyl chloride is produced and capable of being detected in a reactor outlet stream or a recycle gas loop; b. increasing the temperature of the high selectivity epoxidation catalyst to at least about 220° C.; c. subsequently reducing the level of organic chloride in the feed over a period of from about 12 to about 36 hours so as to increase the temperature of the catalyst to a temperature of from about 250° C. to about 265° C.; and d. subsequently adjusting the level of organic chloride in the feed to a value sufficient to produce ethylene oxide at a substantially optimum selectivity at a temperature of from about 250° C. to about 265° C.

    摘要翻译： 本公开提供了启动乙烯环氧化方法的方法，包括：a。 使高选择性环氧化催化剂与包含乙烯，氧气和有机氯化物的进料接触一段时间，使得生产氯乙烯并能够在反应器出口流或再循环气体回路中检测; b。 将高选择性环氧化催化剂的温度升高至至少约220℃。 C。 随后在约12至约36小时的时间内降低进料中有机氯化物的水平，从而将催化剂的温度升高至约250℃至约265℃的温度; 和d。 随后在约250℃至约265℃的温度下将进料中的有机氯化物的水平调节至足以产生环氧乙烷的值，其值基本上为最佳选择性。
