ZnSAPO-34 zeolite was prepared by a facile in-situ synthetic route using ZnO as the zinc source, and its catalytic properties in MTO reaction was comprehensively compared with that of SAPO-34 zeolite and Zn/SAPO-34 zeolite prepared by an impregnation method. The physicochemical properties of SAPO-34, ZnSAPO-34 and Zn/SAPO-34 zeolites were characterized by XRD, SEM, N2 adsorption–desorption, NH3-TPD, XRF, and TGA. The evaluation results show that ZnSAPO-34 zeolite, like Zn/SAPO-34 zeolite, is also a highly selective catalyst for ethene production from methanol, with 99.95 wt% of methanol conversion and 51.16 C-% of ethene selectivity.

通过 ZnO 路线简便合成 ZnSAPO-34 沸石

以ZnO为锌源，采用简便的原位合成路线制备了ZnSAPO-34沸石，并综合比较了其在MTO反应中的催化性能与SAPO-34沸石和浸渍法制备的Zn/SAPO-34沸石的催化性能. SAPO-34、ZnSAPO-34 和 Zn/SAPO-34 沸石的理化性质通过 XRD、SEM、N2 吸附-解吸、NH3-TPD、XRF 和 TGA 进行表征。评价结果表明，ZnSAPO-34沸石与Zn/SAPO-34沸石一样，也是甲醇制乙烯的高选择性催化剂，甲醇转化率为99.95wt%，乙烯选择性为51.16C-%。
