本文叙述了Fe-M/Al_2O_3催化剂对α-甲基苯乙烯(α-MS)气相选择催化加氢转化成异丙苯试验研究的初步结果.探讨了温度、氢/α-MS比、空速等对反应的影响,以及适宜的反应条件。该催化剂具有空速大、压力低、收率高及选择性佳等特点.在常压、反应温度360℃、α-MS空速1.33小时~(-1)及氢/α-MS体积比为1250的条件下,α-MS转化率为96.7％,异丙苯收率为92.2％.选择性为95.1％.
In this paper, the preliminary results of selective catalytic hydrogenation of α-methylstyrene (α-MS) to cumene over Fe-M / Al 2 O 3 catalyst were described. The effects of temperature, hydrogen / α-MS ratio, Such as the impact of the reaction, and the appropriate reaction conditions. The catalyst has characteristics of large space velocity, low pressure, high yield and good selectivity, etc. At atmospheric pressure, the reaction temperature is 360 ° C, the space velocity of α-MS is 1.33 h -1 and the volume ratio of hydrogen / α-MS is 1250, the α-MS conversion was 96.7%, the cumene yield was 92.2%, and the selectivity was 95.1%.
