Abstract:The study on the decomposition of mixed VOC(s) has significance value for that the exhaust gas from manufactory is usually mixture of kinds of VOC(s). This experiment chose four kinds of VOC(s) (acetone, benzene, tetrachloroethylene and m-xylene) as the treatment objects to study the decomposition characteristics of mixed VOC(s) by the bipolar pulsed DBD (bipolar pulsed power introduced into dielectric barrier discharge reactor). The results indicated that this bipolar pulsed DBD system could effectively decompose the mixed VOC(s) and the energy efficiency increased greatly compared with single-compound. On the other hand, the decomposition characteristics of mixed components were different from single-compound because of the interaction effect in the mixture. In addition, when the capacitance of the pulse capacitor was at an appropriate range, the DBD reactor could be injected more effective energy, higher level energetic electrons and active particles which could enhance the removal efficiency of the mixed VOC(s). A higher discharge length also could increase the removal efficiency of mixed VOC(s) for that it could enhance the input power and the residence time of mixed VOC(s) in the discharge region*.
