摘要

为了研究挥发性有机化合物的降解特性，将气态苯引入线-筒式介质阻挡放电反应器，利用双极性脉冲高压进行降解考察了放电间隙、放电长度和Mn/γ Al2O3催化剂对苯降解的影响结果表明：在相同电压下，小放电间隙注入的能量较大，有利于苯的降解，放电间隙对苯的降解效果影响由大到小依次为3.5 mm、6 mm、8.5 mm；苯的降解率随着放电长度的增加而增大；加入Mn/γ Al2O3，进一步提高了苯的降解率，Mn质量分数增大到15%时，苯的降解率和碳氧化物选择性都有所提高，分别为91.8%和94.6%

Abstract

To investigate the decomposition characteristics of volatile organic compounds (VOCs)

gaseous benzene was introduced into the wire-cylinder dielectric barrier discharge (DBD) reactor and degraded by bipolar pulsed high-voltage. The effects of discharge gap

discharge length and Catalyst Mn/ γAl2O3 on the degradation of benzene were studied. The results indicate that: under the same voltage

the reactor with a small discharge gap has the larger injecting energy

which is favorable for the degradation of benzene; the order of the positive effect of discharge gap on the removal of benzene is 3.5 mm>6 mm>8 mm; the decomposition efficiency of benzene increases as the discharge length increases; more benzene is further removed due to the addition of Mn/ γAl2O3; the degradation efficiency of benzene and the carbon oxides selectivity are both improved with the amount of Mn increasing to 15%，91.8% and 94.6% respectively.
