AbstractNon-thermal plasma has been studied to remove nitrogen oxides. In order to improve both high removal and energy efficiency, the combined process of the catalyst with the non-thermal plasma was examined experimentally. Hydrocarbons were added where real exhaust gas contains hydrocarbons from incomplete combustion. However zeolite catalysts have shown NOx adsorption at room temperature. For decreasing the NOx adsorption on the catalyst surface, a plate type reactor, which has mesh electrodes and dielectric barriers inside, has been developed. Adsorption characteristics of zeolite catalyst were investigated by measuring time dependence of NO or NOx concentrations. They were hardly observed in these experiments, since, quantities of catalyst were very small (4-5%) compared to that of wire-cylinder reactor.
