摘要
苯-甲苯-二甲苯混合物(BTX)等低碳芳烃是重要的化工原料,未来几年在全球仍将保持较大需求量,目前产能尚无法满足市场需求.为此,有学者提出将催化裂化轻循环油(LCO)作为原料生产高附加值BTX的工艺路线.基于此,探讨了LCO中各类分子加氢裂化的反应网络和机理,以期为业界了解该技术发展情况提供便利.
Abstract
Benzene,toluene,xylene(BTX)and other low-carbon aromatics are important chemical materials,and will maintain large demand in the world in the next few years,but the current capacity can not meet the market demand.Therefore,many researchers have proposed a process route to produce high value-added BTX by using FCC light cycle oil(LCO)as a feedstock.This review focuses on the reaction network and mechanism of hydrocracking of various types of molecules in LCO so as to facilitate the industry to understand the development of this technology.
