摘要 综述了甲醇制低碳烯烃(MTO)过程中吸附、扩散和反应过程对催化剂失活的影响,其中催化剂表面积炭是MTO工艺失活的主要因素,同时介绍了甲醇催化转化低碳烯烃过程催化剂结构对反应活性和选择性的影响。 The effects of adsorption,diffusion and reaction process of methanol to olefins（ MTO） on the deactivation of the catalyst are reviewed. Coke formation is the main factor of MTO deactivation. The influences of catalyst structures on the reaction activity and selectivity of MTO is introduced as well.
