低温等离子体协同催化技术降解VOCs现状

【摘要】 VOCs不仅直接对人体产生危害,而且在大气中参与光化学反应引发雾霾和其他污染天气。近年来,低温等离子体技术因其在室温下具有反应速率快、高效性受到广泛关注。介绍了低温等离子体的定义、分类、工作机理等方面,并着重阐述了几种影响低温等离子体降解VOCs的因素。现阶段研究表明,反应器模块、电源参数、输送气体、臭氧浓度、湿度及污染物浓度等因素在低温等离子体技术及低温等离子体协同其他技术降解VOCs时起到了关键性作用。更多还原

【Abstract】 Volatile Organic Compounds(VOCs)is not only directly harmful to human health,but also involved in photochemical reactions in the atmosphere,which causing smog and other polluted weather. Recently,it has been found that low-temperature plasma technology has attracted widespread attention due to its rapid reaction rate and high efficiency at room temperature. In this paper,introduces the definition,classification,working mechanism and other aspects of non-thermal plasma,and focuses on several factors that affect non-thermal plasma degradation of VOCs. Researches shown that factors such as reactor modules,power supply parameters,transport gas,ozone concentration,humidity,and contaminant concentration play a key role in non-thermal plasma technology and non-thermal plasma combined with other technologies for the degradation of VOCs.更多还原
