摘　　要：为实现工业有机废气的高效净化,探索了多组分VOCs催化燃烧过程的反应机制及催化剂构-效关系,整理了多组分VOCs催化燃烧的研究进展,总结了不同组分VOCs在催化剂上的“混合反应”特征,分析了影响其催化反应过程的主要因素,提出了多组分VOCs催化剂的设计思路,展望了多组分VOCs催化控制的研究方向。分析表明:多组分VOCs间的“混合效应”受VOCs的性质、催化剂的性质、反应温度、反应产物等因素的影响,通常表现为单向干扰、相互干扰及相互独立3种形式,通过VOCs分子间(或其与活性氧物种间)的竞争吸附、加速产物脱附等过程显著影响多组分VOCs的催化燃烧反应行为。In order to achieve efficient purification of industrial organic waste gas,the reaction mechanism of the catalytic combustion process of multi-component VOCs and the structure-activity relationship of the catalyst were explored.The research progress of catalytic combustion of multi-component VOCs was summarized.The"mixed reaction"characteristics of different components of VOCs on catalysts were summarized.The main factors affecting the catalytic reaction process were analyzed.The design approach of multi-component VOCs catalyst was proposed,and the research direction of multi-component VOCs catalytic control was looked forward.The analysis shows that the"mixing effects"among multi-component VOCs are influenced by the properties of VOCs and catalysts,reaction temperature,reaction products and other factors.Generally,"mixing effects"are observed in three forms of one-way interference,mutual interference and mutual independence.The catalytic reaction behavior of multi-component VOCs was significantly affected by the competitive adsorption among VOCs(or between VOC molecules and reactive oxygen species)and accelerated desorption of products.
