含氯挥发性有机物(CVOCs)由于其毒性、高稳定性和在环境中的持久性而备受关注,有效脱除CVOCs是环境治理领域面临的重要课题,也成为近年来研究的热点。催化燃烧或氧化法因其能耗和成本低有望成为最有效脱除CVOCs的方法之一。对催化燃烧脱除CVOCs的研究进行了综述,重点总结和评述了催化燃烧脱除CVOCs的催化剂,包括金属氧化物、过渡金属氧化物和钙钛矿复合氧化物等催化剂,简要阐述了催化剂的失活类型和再生方法,并对未来催化燃烧法脱除CVOCs的研究进行了展望。
Due to their toxicity, high stability and persistence in the environment, chlorine-containing volatile organic compounds (CVOCs) have attracted much attention. Effective removal of CVOCs is an important issue in the field of environmental management and has become a hot spot in recent years. Catalytic combustion or oxidation is expected to be one of the most effective ways to remove CVOCs due to its low energy consumption and cost. The research on the catalytic combustion removal of CVOCs is reviewed. The catalysts for the catalytic combustion removal of CVOCs, including the catalysts of metal oxides, transition metal oxides and perovskite oxides, are briefly summarized and reviewed. The catalyst losses Live types and regeneration methods, and prospects for the future catalytic combustion removal of CVOCs are prospected.
