Abstract

Diesel exhaust is one of major sources of air pollutants, in general and oxides of Nitrogen (NOx), in particular. To control the impact of NOx on environmental pollution, it is necessary to abate the same from Petro-diesel exhaust. This paper explores the direct non-thermal plasma method for reduction of NOx. A Duct type reactor has been designed and implemented to produce dielectric barrier discharge (DBD) plasma for treating the exhaust. Since plasma alone cannot remove NOx completely, an additional treatment is therefore necessary. Plasma treated exhaust was made to flow through pellets made out of lignite Fly ash, an industrial waste. It was observed that the synergetic effect of DBD plasma and Lignite Fly ash has resulted in about 75 NOx removal efficiency. The industry waste behaves more as an NO2 adsorbent than NO one. The paper ends with a comparative study of NOx removal based on plasma and plasma plus adsorbent techniques.
