摘要
非临氢条件下用固定床反应器研究了环己烷、辛烯-1及正辛烷在超细HZSM-5上的芳构化反应,并与微米HZSM-5作了比较.结果表明,在三种反应物中,辛烯-1反应活性最高,正辛烷次之,环己烷最低.不同反应物在两种晶粒度的HZSM-5上生成的芳烃分布大致相同.超细HZSM-5对原料的转化率、芳构化率以及自身的活性稳定性均明显高于微米沸石.在相同反应条件下超细沸石的积炭量低于微米沸石.
In this article, the aromatizations of several compounds over superfine and microcrystal HZSM-5, such as octene-1、 cyclohexane、 n-octane are investigated. The results show that Superfine HZSM-5 has a stronger reactivity to convert hydrocarbons into aromatics and better durability than microcrystal ones, and the coke of superfine zeolite is lower than microcrystal zeolite. Meanwhile, the mechanism of aromatization is discussed.
