Abstract

The paper focuses on treating the oxides of nitrogen (NOx) present in a biofuel exhaust in a non-conventional way. The biofuel or biodiesel is obtained from pongamia pinnata, a native Indian plant. While the biodiesel emissions have lesser amount of carbon-monoxide and hydrocarbons, it has increased concentration of NOx which needs to be addressed. Dielectric barrier discharges energized by high voltage repetitive pulses were used to cause the chemical reactions in the plasma reactor. The plasma reactor is a dielectric glass reactor with a concentrically placed screw type electrode. To enhance removal of NOx the plasma treatment reactor was connected in cascade with an adsorbent reactor. Pellets made out of lignite fly ash, an industrial waste product, were used as adsorbents. This is a first-time attempt to study plasma-lignite synergistic effect on exhaust gas treatment. Results indicate significant removal of NOx under the laboratory conditions in the cascaded plasma-adsorbent treatment. (C) 2018 Elsevier Ltd. All rights reserved.
