Development of Environmental Protection Technologies for Atmosphere by Using the Non-Thermal Plasma

开发了高压非热等离子体分解氯氟烃和挥发性有机化合物（VOCs）等稀释有毒气体的技术。等离子体处理后，在室温下通过mno2负载氧化铝催化剂，以10 J/l的比能密度分解空气中99%以上的三氯乙烯（TCE），但完全氧化TCE需要10倍以上的比能密度。对等离子体进行了光学诊断，并利用等离子体产生的自由基进行了化学反应分析。

Dilute toxic gas, such as CFC and volatile organic compounds (VOCs), decomposition techniques by using high pressure non-thermal plasma was developed. By passing through MnO2-supported alumina catalyst at the room temperature after the plasma process, more than 99% TCE (trichloroethylene) in the air was decomposed at SED (specific energy density) of 10 J/l but perfect oxidation of TCE needs 10 times more SED. Optical diagnosis of that plasma was developed and chemical reaction with help of the radicals generated by the plasma was analyzed.
