Abstract

Reported in this paper is a feasibility study on the injection of plasma induced N radicals for the abatement of NO and $NO_x$ present in the actual diesel exhaust. The radical laden diesel exhaust was further treated by discharge plasma in a dielectric barrier discharge reactor. N radicals were produced in a separate plasma reactor filled with $BaTi0_3$ pellets and were then injected into the treatment zone. There was a significant improvement in the efficiency when the radicals were injected compared to that when there was no radical injection. The efficiency of $NO_x$, removal at 0 load with plasma alone was 14% whereas with the injection of N radicals it went up to 38%. The results of the experiments conducted at different loads are discussed.
