摘　　要：为了提高高溴指数原料工况下芳烃烷基转移装置的运行稳定性,在实验室模拟的高溴指数原料条件下,通过模型反应考察了原料中烯烃组分对芳烃烷基转移反应的影响,并通过调整反应温度、循环氢纯度等操作条件对芳烃烷基转移反应工艺进行了优化,为工业装置的运行优化提供了理论依据。基于实验室考察结果,通过对反应温度、循环氢纯度等工艺参数的优化,以及更换白土操作,提高了高溴指数原料工况下工业装置的运行稳定性和原料转化率,为高溴指数原料工况下芳烃烷基转移装置的运行优化提供了参考。In order to improve the operation stability under the working condition of high bromine index feedstock,the effect of olefin components on aromatic transalkylation reaction was investigated through model reaction in the laboratory.The process conditions were adjusted and optimized by adjusting the reaction temperature and recycle hydrogen purity,which provided a theoretical basis for the operation optimization of industrial plant.Based on the laboratory results by optimizing process parameters such as reaction temperature and recycle hydrogen purity,as well as replacing clay operation,the reaction stability and conversion of industrial plant under the working condition of high bromine index feedstock were significantly improved.The results provide a reference for the operation optimization of aromatic transalkylation unit under the working condition of high bromine index feedstock.
