摘　　要：现代化工行业中,由于催化重整、蒸汽裂解生产乙烯等装置不断扩能,导致重芳烃产量巨大,其组分复杂且难以分离,利用率极低,重质芳烃轻质化技术在未来发展尤为关键。文中阐述了国内外重质芳烃轻质化技术研究中的3种反应类型,证明了基于分子筛改性对轻质化技术的重要性,分析了在重芳烃轻质化的工业应用中面临的挑战与未来展望,为企业绿色化发展提供研究依据。In the modern chemical industry,due to the continuous expansion of catalytic reforming,steam cracking production of ethylene and other devices,resulting in a huge production of heavy aromatics,whose components are complex and difficult to separate,and the utilization rate is extremely low,the lightening technology of heavy aromatics is especially critical in the future development.This paper demonstrates the importance of lightening technology based on zeolite catalyst modification by describing three types of reactions in the research of heavy aromatics lightening technology at home and abroad.It also analyzes the challenges and future prospects in the industrial application of heavy aromatics lightening,and provides research basis for the green development of enterprises.
