Method for preparing propylene through converting methyl tert-butyl ether

The invention relates to the field of petrochemical engineering, and discloses a catalyst for preparing propylene through conversion of methyl tert-butyl ether, a preparation method of the catalyst and a method for preparing propylene through conversion of methyl tert-butyl ether. The method comprises the following steps: a raw material containing methyl tert-butyl ether is contacted with a catalyst, wherein the catalyst comprises a zeolite molecular sieve, a binder and a modification component, and based on the total weight of the catalyst, the content of the zeolite molecular sieve is 40-90 wt%, the content of the binder is 10-30 wt%, and the content of the modification component is 0.5-10 wt%. According to the method, the problem of excessive production of MTBE can be solved, and the yield of the important chemical raw material propylene is increased. 本发明涉及石油化工领域，公开了一种甲基叔丁基醚转化制丙烯催化剂及其制备方法以及甲基叔丁基醚转化制丙烯的方法。其中，该方法包括：将含有甲基叔丁基醚的原料与催化剂进行接触，其中，所述催化剂包括沸石分子筛、粘结剂和改性组分，且以所述催化剂的总重量为基准，所述沸石分子筛的含量为40-90重量％，所述粘结剂的含量为10-3
