摘　　要：研究了采用大孔小晶粒分子筛作为活性组分,非贵金属改性以提高反应的稳定性的脱烯烃TCDTO-1催化剂。由小晶粒分子筛制备的脱烯烃TCDTO-1催化剂具有良好的扩散性能、脱烯烃活性和稳定性,在原料溴指数、温度、压力、空速等反应条件一致前提下,其单程寿命为白土的10倍以上。催化剂再生2次后脱烯烃活性略有下降,但是单程寿命有所提高。催化剂精制后产物分布和白土相比无明显变化。TCDTO-1 catalyst can be used in the refining process of mixed C8^＋ aromatics,in which nanosized molecular sieve with large pore structure is used as active component and non-noble metals are used to improve the reactive stability.The results of stability study show that the running life of TCDTO-1 catalyst is ten times more than that of the industrial activated clay under the same condition.The running life is not obvious declined when the deactivated TCDTO-1 is regenerated two times.The product distribution refined by TCDTO-1 and clay is almost the same.
