Application of plasma chemistry for gas cleaning is gaining prominence in recent years, mainly from an energy efficiency point of view. In this paper we conducted a comparative study of $NO/NO_x$ removal using two different types of dielectric barrier discharge electrodes, wire-cylinder reactor, pipe-cylinder reactor. Investigations were first carried out with synthetic gases to obtain the baseline information on the $NO/NO_x$ removal with respect to the two geometries studied. Further, experiments were carried out with raw diesel exhaust under loaded condition. A high $NO_x$ removal efficiency of 90% was observed for the pipe-cylinder reactor as compared to that of 53.4% for the wire-cylinder reactor. Furthermore, for the same energy consumed per NO molecule (about 73 eV/NO molecule), the removal efficiency increased from 67% for the wire-cylinder to about 98% for the pipe-cylinder which was quite appreciable.
