改性ZSM-5甲醇芳构化催化剂研究进展

摘要

综述了甲醇芳构化催化剂ZSM-5的改性处理，包含金属改性、双组分改性以及非金属改性的最新研究成果。经过改性的ZSM-5在甲醇芳构化反应中可以表现出芳烃产率、选择性、寿命等能力的提升。但是目前甲醇芳构化反应的BTX选择性较低，需要在选择适宜的助剂和改性条件方面进一步的探究。%The latest research results of the modification of ZSM-5 for methanol to aromatics were reviewed, including metal modification, two-component modification and non-metallic modification. The modification of ZSM-5 could improve the yield and selectivity of aromatics and catalyst life in methanol aromatization reaction. But at present BTX selectivity in the aromatization reaction of methanol was low, and further exploration in the choice of appropriate promoters and modification conditions would be needed.
