Abstract
Odor control has gained increased importance for ensuring a comfortable living environment. In this paper, the authors report the experimental results of a study of the detailed characteristics of a barrier-type packed-bed nonthermal plasma reactor used for odor control. This plasma reactor has been widely used for VOC (volatile organic compounds) decomposition and NO_x reduction. This reactor is energized by a low-cost 60Hz AC power supply. The removal efficiencies and byproduct concentrations are studied under various experimental conditions. The complete decomposition of the main odor component-NH_3-is obtained with a minimum amount of reaction byproduct formation in a dry environment. The decomposition is deteriorated by the addition of moisture. The minimum residence time is determined for the complete removal of NH_3 in the case of the packed-bed plasma reactor. Mixing another odor component such as CH_3CHO has little effect on the removal efficiency of NH_3.
