摘要
本文通过对不同焙烧温度Co／HZSM—5中Co存在化台态及不同温度下还原Co存在价态的研究，并结合活性评价结果，得到Co在催化剂中存在的化合态和价态对由和乙烯一步法合成苯乙烯反应活性的影响关系．
This article studied on the existance form of Co at different burning tempera ture in Co /HZSM-5 and existance valence state of deoxidation Co at different tempera ture. combined activity evaluation consequence. obtain the influence relation to benzene and ethylene synthetise phenylethyleneby one step process of reaction activity of Co' s existance form and valence state in the catalyst.
