A plasma catalytic method using cycled storage-discharge mode, provides a feasible solution for commercialization of plasma technology in environmental protection. Hence the cycled mode is employed in this project. To achieve the objective of low energy cost and complete oxidation of monoaromatic hydrocarbons, reaction mechanism and optimization of outer parameters for plasma catalytic oxidation of monoaromatic hydrocarbons are studied from microcosm to macrocosm. The main research work includes gas-phase elementary reactions of the plasma and their kinetics, plasma catalytic oxidation pathways of the surface species on the catalysts and their surface reaction kinetics, dependence of plasma catalytic oxidation for the surface species on key inner parameters and active species of plasma, correlation of outer parameters with inner parameters and active species of plasma and catalyst surface species. The underlying mechanisms for the plasma catalytic oxidation of monoaromatic hydrocarbons will be clarified. Accordingly, the outer parameters will be optimized. It will lay a theoretical and technical foundation for development and application of the novel plasma catalytic technology in environmental protection.
