摘　　要：介绍了ZSM-5甲醇芳构化催化剂上积炭的生成途径,从溶解性、热稳定性和积炭位置的角度分别对积炭进行了分类,对提升催化剂抗积炭能力的原理进行了分析,并对抗积炭的方法进行了综述。指出通过调变催化剂酸性,改变反应条件来提高催化剂抗积炭能力时,要兼顾催化剂的活性和选择性;调变催化剂的孔结构和粒径,可以同时促进催化剂的活性、选择性和抗积炭能力。The ways of carbon deposition on ZSM-5 methanol aromatization catalyst were introduced.The carbon deposition was classified from the perspectives of solubility,thermal stability and the position of carbon deposition.The principle of improving the anticarbon deposition ability of the catalyst was analyzed,and various anti carbon deposition methods according to the principle was summarized.It was pointed out that the activity and selectivity of the catalyst should be taken into account when changing the acidity of the catalyst and the reaction conditions to improve the anticarbon ability of the catalyst.However,the activity,selectivity and coke resistance of the catalyst could be improved simultaneously by adjusting the pore structure and particle size of the catalyst.
