摘　　要：甲苯歧化与烷基转移技术对劣质资源的利用及芳烃资源结构调整起着重要的作用,文章考察了氢源类型对HAT-199新型甲苯歧化与烷基转移催化剂反应性能及经济效益的影响。研究结果表明:将甲苯歧化与烷基转移单元的补充氢由管网氢更换至成乙烯氢,能有效提高催化剂反应性能,不仅能指导歧化装置性能和效益的调整,还可以为歧化催化剂使用过程中杂质的控制提供借鉴思路,同时可为装置带来明显的经济效益。Toluene disproportionation and alkyl transfer technology plays an important role in the utilization of inferior resources and the adjustment of aromatic resource structure.The effects of hydrogen source type on the reaction performance and economic benefits of HAT-199 novel toluene disproportionation and alkyl transfer catalyst were investigated.The results show that the replacement of the replenishment hydrogen of toluene disproportionation and alkyl transfer unit from pipeline hydrogen to ethylene hydrogen can effectively improve the reaction performance of the catalyst,which not only provide guidance for the adjustment of the performance and benefit of the disproportionation unit,but also provide reference for the control of impurities during the use of the disproportionation catalyst,and bring obvious economic benefits to the unit.
