摘要
以正丁烷（n-C4H10）和正己烷（n-C6H14）作为目标挥发性有机化合物（VOCs）,考察供给电压和背景气氛对降解率和降解产物的影响,探索滑动弧放电降解直链烃过程的降解机理.结果表明,通过增大供给电压提高高能电子密度,可以促进正丁烷和正己烷的降解;正丁烷和正己烷在氮气气氛中的主要的降解产物为CH4、C2H2等C1-C4小分子碳氢化合物,而在空气气氛中的主要降解产物为CO2、CO、H2O和NO2等无机小分子化合物;氧化性粒子在降解过程中起关键作用,背景气体氧气体积分数的提高可以促进正丁烷和正己烷的降解;随着氧气体积分数的增大,CO2、CO和NO2生成量增大,同时也会促进CO向CO2转化.
n-butane （n-C4 H10） and n-hexane （n-CBH14 pounds （VOCs） to investigate the in position rate and by-products of the charge, and the mechanism was also fluences straight of supply chain hyd ） were chosen as the target volatile organic corn voltage and background atmosphere on the decom rocarbon VOCs decomposition with gliding arc dis studied. Results show that the increase of supply voltage can improve the decomposition efficiency by increasing the energetic electrons density; the main decomposition by-products in the nitrogen atmosphere are C1 -C4 hydrocarbons such as CH4 and C2 H2, in contrast, CO, CO2, H2O and NO2 are the predominant decomposition products when the air is chosen as the carrier gas; radical mechanism plays a key role in the decomposition process, and the increase of background oxygen concentration promotes the decompositions of both n-butane and n-hexane; increasing the oxygen concentration can advance the formation of CO2 ,CO and NO2 and promote the conversion of CO to CO2.
