Abstract
Experimental investigations have been made to utilize the oyster shells, a mariculture waste product and ash from lignite fired thermal power plant, for engine exhaust cleaning aided by electrical discharges. Studies were aimed at reducing NOx in biodiesel exhaust with electric discharge plasma in cascade with adsorbent pellets, made out of oyster shells/lignite ash. The biodiesel was prepared using pongamia-pinnata seeds, a native Indian plant. The paper describes the preparation of the pellets and its synergistic effect with plasma discharge which has resulted in NOx removal efficiency as high as 85% under the laboratory load conditions.
