本文研制了一系列用酸组分(H_3BO_3或H_3EO_4)和碱组分(KOH或LiOH)共同改性的KX/KZSM-5双沸石催化剂.这些催化剂具有高的侧链烷基化活性和选择性.用NH_3和CO_2的程序升温脱附对一系列催化剂的酸中心和碱中心进行了物性表征,证明了该反应是酸中心和碱中心的协同催化.
In this paper, a series of KX / KZSM-5 zeolites catalyzed by acid components (H_3BO_3 or H_3EO_4) and alkali components (KOH or LiOH) have been developed.These catalysts have high side chain alkylation activity and selectivity The characterization of the acid sites and the alkali sites of a series of catalysts by temperature programmed desorption of NH_3 and CO_2 demonstrated that the reaction was a synergistic catalysis of the acid site and the alkali site.
