摘要:随着我国芳烃联合装置及大規模乙烯装置的兴建及扩能改造,副产的C。重芳烃会越来越多,通过芳烃増
产技术将低附加値C。重芳烃转化为苯、甲苯、ニ甲苯(BIX)轻质芳烃对于促进企业挖潜増效、拓展芳烃原料
来源具有重要意义。本文以重整C重芳烃和裂解C重芳烃増产BIX为出发点,从反应原理、工艺、催化剂及
优缺点等方面对热加氢脱烷基、催化加氢脱烷基、非临氢脱烷基、两段临氢裂解技术进行概述,并对技术的发

Abstract: With the newly built aromatic combining plant and largc-scalc cthylcnc plants and those
with capacity expansion revamping, thc Cy cavy aromatic byproducts yicld will greatly incrcasc in the
future. The conversion of Co heavy aromatics 1o BTX by aromatics increase technology is of great
significance for the enterprises to tap potentials and expand aromatic raw materials. The technologies
of incrcasing BTX from reforming C and pyrolysis Cy heavy aromatics arc rcvicwcd, including
reaction principles, processes, catalysts, advantages and disadvantages for themo-hydrodealkylation
hydrodealkylation, non-hydrodealkylation and two-stage hydrocracking technologies. Meanwhile, the
prospects and uture development of each technology are also presented. The article points out that
both the increasing aromatic technology from reforming Co and pyrolysis Co heavy aromatics still
havc a lot of problcms, and innovation of proccss and catalyst arc nccdcd to improvc thc tcchnology
Catalylic material is the key o[ the technology innovation and development, and in the fulure the
reaction mechanism, calalyst deactivation mechanism and process engineering issues should be
integrated to develop new efficient catalytic materials, which can promote the innovational
dcvclopmcnt of BTX incrcasc technology from Cy heavy aromatics
