Abstract: 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.
