本发明公开了种甲醇制丙烯MTP失活催化剂的复活剂，所述复活剂选自具有2-6个碳原子的烷基二胺、具有1-6个碳原子的烷基胺和具有1-6个碳原子的烷基醇胺中的种或多种组分。此外，本发明还公开了相应的复活剂溶液以及使甲醇制丙烯MTP失活催化剂复活的方法和用途。采用本发明的复活剂在线处理，可以在不停工、不卸剂的情况下，使得甲醇转化率恢复到99％以上，丙烯选择性提高1～6个百分点，而且大幅延长催化剂在线运转时间。该方法与常规空气再生方法相结合，既可实现节能降耗，又可提高生产效率，并有效延长催化剂使用寿命。 The invention discloses a revivifier of an MTP (methanol to propylene) inactivation catalyst. The revivifier is selected from one or more components of alkyldiamines with 2-6 carbon atoms, alkylamine with 1-6 carbon atoms and alkanolamines with 1-6 carbon atoms. In addition, the invention further discloses a corresponding revivifier solution, a method enabling the MTP (methanol to propylene) inactivation catalyst to be revivified and use of the revivifier solution. The revivifier disclosed by the invention is used for on-line treatment, so that under the condition that working is not stopped, and the catalyst is not unloaded, the conversion rate of methanol is restored to 99% or above, the selectivity of propylene is increased by 1-6%, and the on-line running tim
