“…Our initial objectives were to decompose small concentrations of NO in nitrogen and NO2 in nitrogen under various operating conditions. The results were then compared with experiments done using exhaust gas from a real diesel engine [8]. The main focus was to measure the NO, NOx decomposition efficiency, the power consumed by the reactor and the resultant specific energy consumption (eV/NO, eV/NOX).…”

This paper presents experiments performed using a dielectric barrier discharge for mobile engine pollution control purposes. Measurements of NO, NOx decomposition efficiency and the resultant energy cost was achieved for sample gas mixtures (NO/N2, NO2/N2) and for real diesel engine exhaust gas. Experiment results show that a significant NO decomposition rate of 65-76% (in NO (=644ppm and 166ppm)/N2) can be obtained with the reactor used. The related energy cost was <300eV per NO molecule removed. Experiments in NO/N2 also demonstrated that varying the power injection into the reactor lead to a considerable reduction of the energy cost while keeping high decomposition rate. With diesel exhaust gas, 66% of NO. decomposition (initially 115ppm) was achieved for an energy cost of 464eV/NOx.

A pulsed corona discharge at atmospheric pressure can be used for combustion gas treatment. It is expected to remove NOx and SO2 with low energy consumption. The main process is estimated to be radical reactions such as N and OH with NOx. These radicals are produced by the collisions between fast electrons and major species of combustion gas. This paper presents a new method for the evaluation of the total amount of N atoms produced by corona discharges. The experiment of N2+NO gas treatment was performed changing the initial NO concentration and keeping the discharge input power constant.Analyzing the data at the high NO concentration region, it was shown that the total amount of N atom production was approximately equal to the reduction quantity of NOx. The energy efficiency of N atom production was estimated to be about
