| 摘 要： | 在相同实验条件下,研究了单、双介质阻挡放电反应器的等离子体发射光谱,对苯的降解效率,以及CO和CO2的生成,检测了NO和NO2的浓度.结果表明,与单介质阻挡放电反应器相比,双介质阻挡放电反应器的发射光谱具有红移现象;单、双介质阻挡放电反应器对苯的降解效率、CO2的生成浓度及选择性几乎一致;采用双介质阻挡放电明显降低了CO的生成浓度,CO的生成选择性也有所下降.更为重要的是,双介质阻挡放电反应器极大地降低了NO2的生成,在本文的实验条件下,没有检测到NO.

| Abstract: | A single dielectric barrier discharge(SDBD)reactor and a double dielectric barrier discharge(DDBD)reactor were used to decompose benzene.The optical emission spectroscopy(OES)of these two reactors were detected and compared.The conversion of benzene was analyzed and compared.The concentration of CO and CO2 was also detected.The selectivity of CO and CO2 and carbon balance were also analyzed and compared.Then,NOx(mainly NO2 and NO) concentration was also measured and compared systematically.It was found that... |
