低温等离子体-光催化联合技术处理甲苯的试验研究

Toluene Degradation by Non-thermal Plasma & Photocatalyst

摘要: 以挥发性有机污染物（VOCs）代表物质甲苯为去除对象，采用低温等离子体-光催化联合技术对其降解开展研究。比较了催化剂-等离子体反应器及空管（不加催化剂）反应器对甲苯的降解性能异同；通过正交试验考察分析了放电区长度、催化剂填充长度、频率、电压和处理气量五个因素对催化剂-等离子体反应器的甲苯去除效果的影响，确定了甲苯降解的最优工艺条件。
>Non-thermal plasma coupled with photocatalysis was employed to remove toluene which was a representative pollutant of volatile organic compounds (VOCs). The similarities and differences of catalyst-plasma reactor and empty (without catalyst) reactor on the toluene degradation performance were studied. Furthermore, the effect of discharge zone length, catalyst filling length, frequency, applied voltage and gas flow rate on the toluene degradation of catalyst-plasma reactor was investigated. Based on the experimental results, the optimal conditions of toluene degradation were determined.
