Decomposition of Styrene Gas with Outer Combined Plasma Photolysis(OCPP)Technology

  • 摘要: 开发了用一个高压电源同时产生等离子体和KrI* 准分子紫外辐射的外置式联合等离子体光解(Outer Combined Plasma Photolysis, OCPP)技术,并用于降解模拟流动态苯乙烯气体. 结果表明:在Kr和I2充入量分别为26.60 kPa和6 mg, 气体流速为3.26 m3/h, 初始ρ(苯乙烯)为1 265 mg/m3,外施电压为9.0 kV的条件下,苯乙烯的去除率达84.4%;与介质阻挡放电技术相比,苯乙烯的去除率提高了20.6%,能率提高了5.7 g/(kW·h). 同时,研究了OCPP技术降解苯乙烯的影响因素,包括Kr和I2的充入量、石英材质、气体流速、初始ρ(苯乙烯)及反应器结构. 采用红外光谱仪和气质联用仪分析了结焦产物,探讨了OCPP技术降解苯乙烯的机理.
