【摘要】：含氯挥发性有机化合物(CVOCs)是一类重要的大气污染物,催化燃烧是实现CVOCs高效减排的一种主流处理技术,但工艺过程中存在氯元素易吸附在催化剂表面致使催化剂失活的问题。本文从催化燃烧CVOCs的反应机理、催化剂活性组分、催化剂载体等几个方面,对近年来催化燃烧处理CVOCs的研究进行了综述,其中催化活性组分可分为以钌、钯为主的贵金属催化剂和集中在高活性的过渡金属复合氧化物、钙钛矿型非贵金属催化剂,并重点阐述了水蒸气对催化燃烧CVOCs反应活性的影响及机制。根据国内外研究状况和技术水平,提出了催化燃烧技术的研究及发展方向,充分利用一定浓度水蒸气的优点抑制催化剂氯中毒及产生较低含量的副产物,为CVOCs高效工业化处理提供了重要的参考。
[Abstract]:Chlorinated volatile organic compounds (VOCs) are a kind of important atmospheric pollutants. Catalytic combustion is one of the main treatment techniques to achieve high efficiency emission reduction of CVOCs. However, there is the problem that chlorine is easily adsorbed on the surface of catalyst to deactivate the catalyst.In this paper, the reaction mechanism of catalytic combustion of CVOCs, the active component of catalyst and the support of catalyst are reviewed. The catalytic combustion treatment of CVOCs in recent years is reviewed, among which the active component of catalyst can be divided into ruthenium.Palladium based noble metal catalysts and highly active transition metal complex oxides and perovskite non-noble metal catalysts were used. The effect of water vapor on the catalytic combustion activity of CVOCs and its mechanism were discussed.According to the research situation and technical level at home and abroad, the research and development direction of catalytic combustion technology is put forward. The advantages of a certain concentration of water vapor are fully utilized to restrain the chlorine poisoning of catalyst and to produce lower content by-products.It provides an important reference for the efficient industrialization of CVOCs.
