摘要
介绍了乙烯直接氧化制环氧乙烷工艺中银催化剂助剂的研究进展,以元素周期表为序,总结和分析了碱金属、碱土金属、过渡金属及其他主族元素作为催化助剂的研究和应用情况,并对主要助剂的作用机理进行了探讨。
he latest advance in the promoters of silver catalysts for ethylene epoxidation to ethylene oxide was reviewed. Based on the order of periodic table, the research on and application of the promoters, including alkali-alkaline earth group and the transition group as well as other main groups as the promoters, were summarized and analyzed. The reaction mechanisms of the major promoters were discussed.
