摘　　要：催化氧化法是目前处理挥发性有机物(VOCs)最有效的治理技术之一,但催化剂中毒问题阻碍着催化剂的应用与催化氧化技术的发展。本文介绍了催化氧化VOCs催化剂中毒机制,综述了进行VOCs催化氧化反应的活性测试以及对失活的催化剂进行分析表征两种研究催化剂中毒方法的研究进展。指出:设计出针对性强、抗中毒性能良好且具有大规模工业应用前景的催化剂将是未来的研究方向。Catalytic oxidation is currently one of the most effective technologies for treatment of volatile organic compounds(VOCs),but the problem of catalyst poisoning hinders the application of catalysts and the development of catalytic oxidation technology.This paper introduces the mechanism of catalyst poisoning in catalytic oxidation of VOCs,and reviews the research progress of two methods for studying catalyst poisoning,which are the activity test of VOCs catalytic oxidation and the analysis and characterization of deactivated catalysts.It is pointed out that the design of catalysts with strong pertinence,good anti-poisoning performance and large-scale industrial application prospects will be the future research direction.
