摘　　要：在双碳目标下,新能源对传统化石能源的替代将进一步加速,近年来电动汽车产业的快速发展无疑将极大抑制油品消费,实施“减油增化”是炼厂转型升级的重要方向。芳烃是承接油转化的重要载体,能够为能源结构调整阶段中过剩油品的利用提供解决方案。综述了汽油重组分制芳烃的生产策略及相关技术进展,介绍了重整汽油重组分制芳烃、催化汽油重组分制芳烃、富芳烃汽油馏分加氢脱烷基制苯以及甲苯与重芳烃的烷基转移技术的研究进展与技术特点,为汽油重组分高效转化为苯、甲苯和二甲苯及蒸汽裂解制烯烃的优质原料(乙烷、丙烷)提供了技术方案,对我国未来油品-芳烃-烯烃的一体化发展方向进行了展望。The substitution of new energy for traditional fossil fuels will be further accelerated owing to the carbon peaking and carbon neutrality goals.In recent years,“decreasing the output ratio of oil and increasing that of chemicals” is a significant strategy for refineries,based on the fact of strong inhibition of oil consumption caused by the rapid development and application of electric vehicles.Aromatics are important intermediates for conversion of oil to chemicals,which provide solutions for excess oil resources during the energy restructuring stage.The strategies and related technological progress of aromatics production from heavy components of gasoline were reviewed.The research progress and technical characteristics of catalytic reforming and catalytic cracking heavy components of gasoline to aromatics,hydrodealkylation of gasoline rich of aromatics to benzene and the transalkylation of toluene and heavy aromatics were introduced.These techniques provided solutions for highly efficient conversion of inferior gasoline components to benzene,toluene and xylene,and steam cracking feedstock(ethane,propane).The future development of oil-aromatics-olefin integration in our country was prospected.
