- 双碳背景下炼化企业向化工新材料转型过程中，甲醇耦合轻烃芳构化技术成为轻烃高值化利用的重要方向，催化剂作为该技术的核心，其性能直接决定反应效率、产物选择性及工业应用价值。目前该技术的研究多聚焦于催化性能优化，而针对催化剂失活机制及再生技术的系统研究鲜有报道。文中系统总结了甲醇耦合轻烃芳构化反应中主流催化剂的类型、改性方法及催化特性；深入分析了催化剂积碳、活性组分流失/团聚、分子筛骨架脱铝等主要失活原因；梳理了当前主流的再生技术及工艺优化策略。旨在为开发高稳定性、长寿命的耦合芳构化催化剂提供理论支撑，同时为工业装置中催化剂的高效再生及长周期运行提供技术参考。In the process of petrochemical enterprises transforming to chemical new materials under the background of carbon peak⁃ing and carbon neutrality, methanol coupling with light hydrocarbons aromatization technology has become an important directionfor the high-value utilization of light hydrocarbons. As the core of this technology, the catalyst performance directly determines thereaction efficiency, product selectivity and industrial application value. At present, most of the research on this technology focuseson the optimization of catalytic performance, while systematic research on the catalyst deactivation mechanism and regenerationtechnology is rarely reported. This paper systematically summarizes the types, modification methods and catalytic characteristics ofmainstream catalysts in the methanol coupling with light hydrocarbons aromatization reaction, deeply analyzes the main deactivationreasons such as catalyst carbon deposition, active component loss/agglomeration and zeolite framework dealumination, and combsthe current mainstream regeneration technologies and process optimization strategies. The aim is to provide theoretical support forthe development of coupling aromatization catalysts with high stability and long service life, and at the same time provide technicalreference for the efficient regeneration and long-cycle operation of catalysts in industrial plants.
