| 摘 要： | 在改性的β沸石催化剂上研究了催化精馏法干气制乙苯的工艺过程,考察了各工艺参数对烷基化反应的影响,并提出了适宜的工艺条件:乙烯质量空速小于0 25h-1、进料苯烯摩尔比大于4、反应压力大于1 5MPa、反应温度150～180℃。在此条件下,乙烯转化率大于96%,乙苯选择性大于94%,反应产物中基本上无二甲苯生成。

| Abstract: | Preparation of ethylbenzene with ethylene in dry gas by catalytic rectification process over zeolite β was studied. Effects of technological parameters on the alkylation were investigated. Preferred operating conditions were: ethylene WHSV ≤0 25 h -1 , feed mole ratio of benzene/ethylene≥4, pressure≥1 5 MPa and temperaure 150～180 ℃. Conversion of ethylene was over 96% and selectivity of ethylbenzene was over 94%. Moreover, dimethylbenzene was hardly found in the product. |
