摘要

设计了一种新型的由两个独立发电机驱动的体积表面填料床DBD反应器（V-S PDBD），用于苯的降解。BaTiO3涂层修饰的多孔陶瓷球（BaTiO3/PC）比玻璃、无孔和多孔陶瓷球等产生更多的电流脉冲，BaTiO3/PC填充反应器的等效介电容量和转移电荷分别是空V-S DBD反应器的1.3倍和1.2倍，说明填充颗粒的孔隙中产生微放电，BaTiO3涂层的极化增强了放电强度。在孔径为75 μm的BaTiO3/PC球团填充的V-SDBD反应器中，苯的最高降解效率为69.5%，能效为1.54 g/kWh。

Enhanced electric discharge in a dual AC powered packed-bed DBD reactor for benzene degradation

A novel volume-surface packed-bed DBD (V-S PDBD) reactor powered by two separate power generators was designed for degradation of benzene. Porous ceramic pellets modified by BaTiO₃ coating (BaTiO₃/PC) generated more current pulses compared to glass, nonporous and porous ceramic pellets, etc., and the equivalent dielectric capacitance and the transferred charges in the reactor packed with BaTiO₃/PC were 1.3 times and 1.2 times higher than empty V-S DBD reactor, implying the production of micro-discharges in pores of packed pellets and the polarization of BaTiO₃ coating enhanced the electric discharge intensity. The highest degradation efficiency of benzene in V-SDBD reactor packed with BaTiO₃/PC pellets (75 μm pore size) reached 69.5 % with an energy efficiency 1.54 g/kWh.
