Abstract :
Recently, air pollution has been a serious problem; photochemical smog and acid rain are typical phenomena. NOx is one of these air pollution substances and is a poisonous gas. A reduction in NOx emissions is therefore desirable. However, the density of NOx in the atmosphere remains at a stable level or worsens. The authors propose a new reactor whose that gap area is filled with glass beads, allowing surface and silent discharges to be generated simultaneously in the same space. In this paper, the removal of NOx from a dry NO/N2 mixed gas by barrier discharge among the glass beads in the reactor is experimentally investigated. The experiments are carried out at a frequency of 50 Hz, applied voltage from 0 to 20 kVpp and gas flow rate from 0.4 to 1.4 L/min
