摘　　要：针对工业烟气中低浓度有机物难以去除,提出采用高吸附能力β分子筛为吸附剂,展开吸附储存和低温等离子体放电原位矿化处理含萘模拟气体。双极性脉冲电源用来驱动介质阻挡放电装置产生等离子体,探究气体流量、功率、温度和储存时间对萘矿化程度的影响。结果表明:气体体积流量为0.25 L·min^(-1)时,放电时间更短;高功率、低温度可增加萘的矿化速率;储存量对碳平衡影响显著,最高可达97.65%。该过程具有反应器体积小、萘矿化率高、臭氧残余量低的优点。Removal of low concentration organic compounds in industrial flue gas is difficult.In this study,βzeolite with high adsorption capacity was used as an adsorbent for adsorption storage and in-situ mineralization of naphthalene containing simulated gas by low temperature plasma discharge.A bipolar pulsed power supply was applied to drive dielectric barrier discharge to generate plasma.Effects of gas flow rate,input power,temperature and storage time on naphthalene mineralization were investigated.The results showed that shorter discharge time could be achieved with 0.25 L·min^(-1)flow rate,and mineralization increased with the increase of power and lower temperature.Moreover,storage capacity had an important effect on carbon balance with the maximum value of 97.65%.This process has the advantages of small reactor volume,high naphthalene mineralization rate and low ozone residual amount.
