采用一种新的制备乙苯的烷基化反应工艺条件，在气－液－固三相的反应状态下考察反应温度、压力、苯／乙烯摩尔比和苯质量空速对以改性β沸石为主要活性组分的ＦＸ－０２催化剂性能的影响。在初步试验的基础上，应用均匀设计方法找出ＦＸ－０２催化剂上苯与乙烯烷基化反应的最适宜工艺条件，在ＦＸ－０２催化剂上，当反应温度为１５０～１７５℃，反应压力为０．８～１．２ＭＰａ，苯的质量空速为４ｈ－１，苯与乙烯摩尔比为６～８时，苯与乙烯可顺利地进行烷基化反应，乙烯的转化率达到１００％，乙苯的选择性超过９５％。
Using a new alkylation process for the preparation of ethylbenzene, the effects of reaction temperature, pressure, benzene / ethylene molar ratio and benzene mass space velocity on the reaction of modified β zeolite As the main active component of FX-02 catalyst performance. Based on the preliminary experiments, the optimum process conditions for the alkylation of benzene with ethylene over FX-02 catalyst were found by the uniform design method. On the FX-02 catalyst, when the reaction temperature was 150-175 ℃, the reaction pressure was 0.8 ~ 1.2MPa, the mass space velocity of benzene is 4h-1, the molar ratio of benzene to ethylene is 6 ~ 8, benzene and ethylene can be smoothly alkylation reaction, the conversion of ethylene reaches 100%, B Benzene selectivity of more than 95%.
