The surface acidity of the ZSM-5 zeolite can be measured using a front-chromatograph carring in the organic base and combining with TPD technique.
本文介绍了用有机碱的迎头色谱法配合TPD技术测定ZSM-5分子筛催化剂的表面酸性,以甲醇转化高辛烷值汽油的HZSM—5催化剂为例,观察到了它有与Y型及氢丝光沸石不同的高温部分强酸峰,因此它能使甲醇转化成高辛烷值汽油,随着催化剂再生次数的增加,酸量逐渐减少,强酸峰顶温度向低温方向转移,油品中芳烃含量也逐渐降低。
