AbstractIn order to remove NO from diesel exhaust gas, non-thermal plasma methods have been extensively studied. However, it is known that one of the problems of the de-NOx process by non-thermal plasma is the relatively high energy consumption of the de NOx process. In this paper, we tried to solve this problem by using a water emulsion fuel. Since the use of water emulsion fuel reduces the combustion temperature in the engine, the NO concentration at outlet of the engine should decrease considerably. We prepared a water emulsion fuel with different water content, and carried out NO removal experiments for diesel exhaust gas by both direct discharge and by an ozone injection methods. The experiments showed that a large reduction of discharge power for de-NOx process could be achieved.

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.
