摘　　要：研究了苯进料对HAT-099甲苯歧化与烷基转移催化剂反应性能的影响,并对反应过程及行为进行了分析。结果表明:在原甲苯歧化与烷基转移反应进料中添加苯,能有效降低苯的生成量,提高碳九及以上芳烃(C9^+A)的转化效率。将反应原料调整为苯与C9^+A进行烷基转移反应,可生产市场需求量更大的甲苯和二甲苯,同时缓解苯产量过剩的压力。The effects of benzene feed on the reaction performance of HAT-099 toluene disproportionation and transalkylation catalyst was studied,and the reaction process and behavior were analyzed.The results show that the addition of benzene to the feed of disproportionation and transalkylation reaction can effectively reduce the production of benzene and improve the conversion efficiency of C9^+aromatics(C9^+A).Adjustment of the reaction to transalkylation reaction of benzene and C9^+A can produce toluene and xylene with greater market demand,and at the same time relieve the pressure of benzene overproduction.
