摘要: 氯苯类(CBs)化合物的排放给环境带来严重的污染和危害。本文回顾和总结了近几年来的氯苯类挥发性有机污染物的处理方法,综述了所采用催化剂的国内外研究现状,并对不同种方法进行优缺点分析。结果表明:催化燃烧法是最具有应用前景的、最有效的处理CBs的技术之一,该法优势是能够在催化剂存在的条件下,高效地处理低浓度的污染物,操作温度低,避免了氮氧化物的产生。应用于催化燃烧的催化剂类型繁多,贵金属催化剂具有高活性但对高温敏感;过渡金属氧化物催化剂的抗氯中毒能力较强;钙钛矿类催化剂廉价易得,其A、B位原子具有良好的可调性,并可通过负载与改性弥补其反应温度高及易失活等缺点。与其他催化剂相对比,钙钛矿类催化剂具有更广泛的应用前景。

Abstract: Emission of chlorobenzenes (CBs) substance has caused serious pollutions to our environment. This paper reviewed the approaches of treating chlorobenzene volatile organic compounds in recent years, and also summarized the research status of catalysts as well as the advantages and disadvantages of different types of methods. The results showed that catalytic combustion treatment method was one of the most promising and effective treatment techniques for CBs, because the contaminants of low concentrations could be disposed effectively with the help of catalysts at low operating temperature with no nitrogen oxides generated during the process. Many types of catalysts can be applied to the catalytic combustion. While the noble metal catalysts have high activity but sensitive to temperature, and the transition metal oxide catalysts have strong ability to resist chlorine poisoning, the perovskite-based catalysts have wider applications. Perovskite-based catalysts are inexpensive and easy to obtain, and the A and B atoms in the molecular have a good adjustability. By means of loading and modifying the catalysts, the disadvantages of high reaction temperature and easy inactivation can be overcome successfully.

Key words: catalytic combustion, catalyst, organic compounds, chlorobenzenes, perovskite-based catalysts
