摘　　要：首先综述MTP催化剂的特性,然后从MTP反应机理出发,对循环烃在实际作用进行分析。结果表明,循环烃在实际生产中有着提高丙烯收率的积极意义。在催化剂前周期,丙烯选择性较低,丙烯转化率不高。随着运行周期的增加循环烃的加入有助于进一步提高丙烯选择性和丙烯收率。The characteristics of MTP catalysts are reviewed flrstly,and then the actual action of cyclic hydrocarbons is analyzed from the mechanism of MTP reaction.The results show that circulating hydrocarbon has positive signiflcance in improving the yield of propylene in practical production.In the former period,propylene selectivity is low and propylene conversion is not high.The addition of cyclic hydrocarbons with the increase of operation period is helpful to further improve the selectivity of propylene and the yield of propylene.
