Influence of Ratio of NO/NO2 on NOx Removal using DBD with Urea Solution
Air pollution due to the exhaust gas from motorcars causes serious environmental problems, so it is necessary to remove NOx from the exhaust gas. In this study, NOx removal by dielectric barrier discharge (DBD) with an urea solution without any catalyst at room temperature has been investigated. The NOx removal rate and NOx removal efficiency has been measured with and without adding an urea solution. Furthermore, the influence of the ratio of NO and NO2 on the amount of removed NOx by DBD with the urea solution in actual apparatus has been measured experimentally. The ratio of NO and NO2 of an initial mimic exhaust gas was adjusted by DBD treatment. From the results of measurement, it has been found that NOx removal by DBD with an urea solution is effective and the optimum concentration of the urea solution is 23％ in the present study. And it was estimated that the optimum ratio of NO and NO2 is about 6 to 1 for NOx removal with an urea solution.
