Abstract
The purpose of this study is to investigate the possibility of removing NOx contained in combustion exhaust gases by N2 plasma injection. The simulated exhaust gas (N2+O2+CO2+NO) was mixed with nitrogen atoms produced in the N2 plasma, and the effects of O2 and CO2 on the reduction of NOx and CO generation were studied experimentally. The NOx removal ratio η of 40 to 50% is observed under the conditions of O2 concentration, 3 to 5%, plasma power, 600W, and CO concentration contained in gas, about 300ppm. Removal ratio η is highest for a low reaction temperature less than 500K. The value of η is reduced to 20% due to the addition of H2O to gas. However, the recovery of η is obtained by changing the gas injection site to plasma; this is caused by the decrease of OH radical formation. Retention time required for reaction is on the order of several tens of milliseconds.
