摘要
利用介质阻挡放电产生的非平衡等离子体对汽车尾气中CO的净化进行了研究。分别考察了放电电压、CO初始浓度、气体流量及氧气和水蒸气对CO转化的影响。结果表明 :在介质阻挡放电等离子体作用下CO主要转化为CO2 ;随着电压的升高 ,CO的转化率增大 ;随着初始浓度和流量的增大 ,CO的转化率减小 ;引入O2 和水蒸气后 ,CO的转化率得到了明显提高。
In non-equilibrium plasma produced by dielectric barrier discharge, removal of CO from automobile exhaust has been studied. Effects of electrical discharge voltage, CO initial concentration, gas flow rate as well as the contents of O 2 and H 2O on the conversion of CO were investigated, respectively. Experimental results showed that CO was mostly converted to CO 2 under dielectric barrier discharge plasma. The conversion of CO was increased with increasing electrical discharge voltage. Moreover, the increasing of CO initial concentration and gas flow rate, the conversion of CO was decreased. After adding to O 2 and H 2O, the conversion of CO was obviously promoted. In addition, mechanism of CO conversion under dielectric barrier discharge plasma was discussed.
