摘要: 以模拟汽油为原料, 用小型间歇式反应器, 对4种 Y型分子筛催化噻吩—烯烃的烷基化反应性能进
行评价。实验结果表明: 分子筛 U S Y1 烷基化的活性和控制烯烃聚合明显优于其他3种催化剂。U S Y1 分子筛催化
噻吩—烯烃烷基化的最佳反应条件是: 反应温度为1 4 0曟、 反应时间为2h、 剂油质量比为1暶1 0。在最佳反应条件
下, 噻吩转化率为8 8. 1 7%, 且重复使用4次催化剂仍具有较高的催化活性。

Abstract: atalytic alkylation of thiophene with laurylene by four kinds of Y zeolite catalyst was evaluated with gasoline as raw material in a small batch reactor. The experimental results show that USY1 molecular sieve shows highest alkylation activity and better selectivity than the other three catalysts. The optimum conditions of catalytic alkylation by USY1 molecular sieve was as follows: the reaction temperature 140 ℃, reaction time 2 h, catalyst to oil ratio 1∶10. Under above conditions, thiophene conversion rate could reach 88.17%, and high activity could be kept after recycling the catalyst 4 times. 
