Abstract
Decomposition performance of non-thermal plasma for volatile organic compounds (VOCs) such as chlorofluorocarbon (CFC), chlorohydrocarbon and other typical organic materials, were studied experimentally. DeNOx process of the non-thermal plasma for the flue gas was also tested. Frequency dependence of plasma exciting voltage including pulse and AC, humidity effects (OH radical effects) on the plasma processing and reactor geometry effects were studied to understand the decomposition mechanism and optimize the power efficiency of the processing. 500 Hz or 1kHz excitation is found to be the upper limit to realize good decomposition efficiency of VOCs or good reduction of NOx. Higher frequency causes other loss by heating residual ions. Pulse excitation was much better than the AC excitation, especially at the high decomposition rate of the VOCs.
