催化剂强化脉冲放电治理有机废气

为增强对有机废气治理的有效性，本文研究了以催化剂协助脉冲放电的新方法对放电条件下的催化技术进行实验研究．结果表明，Mn、Fe等金属氧化物在放电作用下对有机物的降解有较好的催化活性，二者可使甲苯的去除率由59％分别提高到86％和83％；以陶瓷材料为载体用浸渍法制备的催化剂活性及稳定性较好；考察了反应器的结构、电压峰值Vp和催化剂的制各条件对催化效果的影响以及催化剂对不同有机物降解的促进作用

Utilizing catalyst to enhance pulse discharge for volatile organic compounds treatment

In order to enhance the removal efficiency of volatile organic compounds (VOCs), a new method employing catalyst to enhance pulse discharge was studied in this paper. The technology of catalysis was investigated experimentally under the condition of pulse discharge. The results showed that oxide of Mn or Fe improved the degradation of VOCs greatly and the removal efficiency of toluene was increased from 59% to 86% and 83% respectively. The catalyst impreg- nated on the ceramic tube had better activity and stability. Meanwhile, the main factors that influenced catalysis were in- vestigated.
