【摘要】 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％。更多还原

【Abstract】 The operating conditions for producing ethylbenzene using catalyst with a modified beta zeolite as main component at 3 phase state were studied. The optimum conditions for the alkylation reaction were in a temperature of 150￣175 ℃, a pressure of 0.8￣1.2 MPa, a benzene WHSV of 4 and a benzene to ethylene ratio of 6￣8. Under these conditions, the conversion of ethylene was 100% and the selectivity of ethylbenzene was more than 95.0%.更多还原
