摘要
从银催化剂在乙烯环氧化反应中的作用机理、反应动力学研究、载体制备、助剂优选、制备工艺改进、国内银催化剂的研究及工业应用情况、应用技术改进等方面,对用于制备环氧乙烷的银催化剂近十年的研究进展进行了述评,讨论了银催化剂研究工作中存在的问题和发展方向,指出银催化剂的理论研究相对滞后,需加大基础研究,为开发成本低廉、性能更好的银催化剂提供理论指导。
Recent important advances in the researches of silver catalysts for producing ethylene oxide by the ethylene epoxidation were summarized,which included:catalytic mechanism,reaction kinetics,preparation of supports,optimization of cocatalysts,improvement in the preparation of catalysts and industrial application of the silver catalysts. The questions in the researches and developments were discussed. The problems include that,the theoretical research for the silver catalysts lag behind and the basic research need to be strengthened for the development of the silver catalysts with low cost and high performance.
