| 摘 要： | 在固定床微型反应器中，采用HZSM-5催化剂，对催化裂化干气中乙烯低聚反应进行了研究。结果表明，通过优化反应条件可以达到提高乙烯利用率或提高丙烯收率的目的。使用HZSM-5新鲜催化剂，在温度为400℃，压力为0．1MPa，空速为18h。的条件下，可获得82．28％的乙烯转化率，此时液化气收率为34．46％。使用老化HZSM-5催化剂，在温度为550℃，压力为0．3MPa，总空速为18h^-1，氮气／干气（体积比）为1．0的条件下，乙烯转化率为49．79％，液化气收率为27．33％，丙烯收率为14．47％。

| Abstract: | Oligomerization of ethylene in FCC dry gas was investigated over HZSM -5 catalyst in fixed bed micro -reactor. The results showed that enhancing ethylene conversion or propylene yield could be achieved under the optimum reaction condition. The ethylene conversion and LPG yield was 82.28% and 34.46% respectively under the condition of pressure 0.1 MPa,temperature 400℃ ,space velocity 18 h^-1 using fresh catalyst. When the aged catalyst was used, the ethylene conversion was 49.79% , the LPG yield was 27.33% , propylene yield was 14.47% , under condition of temperature 550 ℃, pressure 0.3 MPa, total space velocity 18 h^-1, nitrogen/dry gas （ volume ratio） 1.0. |
