摘　　要：轻质芳烃苯、甲苯、二甲苯(合称BTX)被广泛应用于橡胶、纺织纤维、药物及香料等大宗产品的合成,是重要的基础有机化工材料。近年来,随着国内石油化工行业蓬勃发展,中国BTX芳烃需求量以每年2%~6%的速度逐年增加,并且对芳烃重整技术环保要求日益严苛,这推动了芳烃重整油脱烯烃剂的不断更新换代。基于此,首先概述了颗粒白土、选择性加氢精制催化剂这两种传统脱烯烃剂的研究现状及存在问题;着重介绍了新兴的分子筛脱烯烃剂的催化、失活机理和工业化应用现状。最后,从分子筛形貌与晶粒尺寸调节、孔道结构调节和酸性调节等三个方面对分子筛改性方法进行了综述,指出未来工业化芳烃连续重整装置用分子筛催化剂的设计和发展方向。Benzene,toluene,xylene(BTX)is wildly used to synthetize high value products such as rubber,textile fibers,pharmaceuticals,and spices as an important raw materials of organic chemical.Recently,with the rapidly development of do-mestic petrochemical industry,the demand for BTX was increased by 2%~6%annually.In addition,the increasingly strin-gent environmental requirements for aromatics reforming technology promoted the continuous development of olefin removal catalyst for aromatic reforming oil.Based on these points,the research status and existed problems of two traditional olefin removal agents including the granular activated clay and selective hydrogenation refining catalysts were summarized firstly.Then,the catalysis,deactivation mechanism and industrial application status of emerging zeolite catalysts were emphati-cally introduced.Finally,the modification methods of zeolite were reviewed from three aspects:morphology and grain size regulation,pore structure controlment,and acidity adjustment.The design and development directions of molecular sieve catalysts for future industrial aromatics continuous reforming units were pointed out.
