A cascaded system of electrical discharges (non-thermal plasma), catalyst and adsorption process was investigated for the removal of nitrogen oxides $(NO_x)$ and CO from a diesel engine raw exhaust. The three processes were sep. studied first, and then the cascaded processes, namely plasma-catalyst and plasma-adsorbent, were investigated. In this paper main emphasis was laid on the effect of carbonaceous soot oxidn. on the plasma treatment process. While the cascaded plasma-catalyst process exhibits a higher CO removal, the cascaded plasma-adsorbent process exhibits a higher NOx removal. The exptseriments were conducted under no-load. The plasma and adsorbent reactors were kept at room temperature throughout the experiment while the catalyst reactor was kept at $200^oC/300^oC$.
