Removal of four kinds of volatile organic compounds mixture in air using silent discharge reactor driven by bipolar pulsed power
چکیده انگلیسی

A silent discharge reactor initiated by bipolar pulsed power substituting the traditional ac power was used to remove the volatile organic compounds (VOCs) mixture of acetone, benzene, tetrachloroethylene and m-xylene. The results indicated that the silent discharge driven by bipolar pulsed power could effectively input pulsed energy, produce strong instant discharge and energetic particles, and thus enhance the removal efficiency of the mixed VOCs. The order of the removal efficiency of mixed VOCs followed as acetone < benzene < tetrachloroethylene < m-xylene no matter what power supply was used. Comparing with single-compound, the removal efficiency of m-xylene only fell a little but those of the other three components fell a lot in the process of the mixed VOCs treatment. In addition, controlling the status of electrical discharge plasma by changing the discharge parameters (such as capacitance of the pulse capacitor and pulse repetitive rate) was found to be an efficient way to enhance the removal efficiency of the mixed VOCs. In this system, the Cp = 2 nF was the optimal capacitance for the bipolar power supply combined with the silent discharge reactor that had the best energy conversion efficiency for removal of mixed VOCs. A higher pulse repetitive rate and longer residence time could also increase the removal efficiency of mixed VOCs.
