摘要
挥发性有机物(VOCs)作为雾霾生成的前体物质,其净化处理已经成为当前大气污染控制的热点问题,催化燃烧法凭借其操作温度低(200~400℃)、安全性高、能耗小等特点成为实际应用中最常用的处理技术之一。本文着重对VOCs催化燃烧机理和催化剂研究进行了综述,分析了Marse-van Krevelen(MVK)、Langmuir-Hinshelwood(L-H)和Eley-Rideal(E-R)三种催化氧化机理模型,阐述了近年来VOCs催化燃烧催化剂的研究进展。
Volatile organic compounds(VOCs)as precursors of haze,its purification has become a hot issue of air pollution control.Catalytic combustion method,with its low operating temperature(200~400℃),high safety,low energy consumption and other characteristics,has become one of the most commonly used treatment technologies in practical application.The mechanism of VOCs catalytic combustion and the research of catalysts were reviewed.Three kinds of catalytic oxidation mechanism models,Marse-van Krevelen(MVK),Langmuir-Hinshelwood(L-H)and Eley-Rideal(E-R),were analyzed.The research progress on VOCs catalytic combustion catalysts in recent years was described.
