摘要
介绍了乙烯氧化制环氧乙烷银催化剂中常见的几种助催化剂:碱金属、卤素、碱土金属、稀土金属、铊、钼、钨、硫、铼、锰和镍等,并对其中的铯、氯、钡、铼的助催化作用机理也作了简要介绍。
In this paper, promoters used frequently in the catalysts for ethylene oxidation to ethylene oxide was introduced in detail.These promoters include alkaline metal,halogen,alkaline-earth metal,rare-earth metal,molybdenum,tungsten,sulfur,rhenium,thallium and manganese and so on.The mechanism of promoting effect of cesium,chlorine,barium and rhenium was also introduced briefly.
