Abstract
연면방전 반응기로부터 발생하는 플라스마에 의해 NO, NO2222
Hazardous air pollutants(HAP)such as NO, NO2 and SO2 were removed in SPCP reactor and the removal efficiencies per unit power of each pollutants were 5.21%Wnfor SO2,4.76%/W for NO and 4.24%/W for NO2. The efficiency was increased by increased by increasing the residence time and by decreasign the initial concentration of pollutants. The highest decomposition efficiency was obtained for the electrode diameter of 3 mm. For the electrode material, the removal efficiency changed with the electrode material in the order of W>Cu>Al. The removal efficiency increased with CH4 content, and HAP was almost completely removed with the efficiency of 99% respectively.
