Abstract
Researches on the elimination of sulfur and nitrogen oxides with catalysts and absorbents reported manyproblems related with elimination efficiency and complex devices. In this study, decomposition efficiency ofharmful gases was investigated. It was found that the efficiency rate can be increased by moving the harmfulgases together with SPCP reactor and the catalysis reactor. Calcium hydroxide(Ca(OH)2), CaO, and TiO2 wereused as catalysts. Harmful air polluting gases such as SO2 were measured for the analysis of decompositionefficiency, power consumption, and voltage according to changes to the process variables including frequency,concentration, electrode material, thickness of electrode, number of electrode winding, and additives to obtainoptimal process conditions and the highest decomposition efficiency.The standard sample was sulfur oxide(SO2). Harmful gases were eliminated by moving them through theplasma generated in the SPCP reactor and the Ca(OH)2 catalysis reactor. The elimination rate and productswere analyzed with the gas analyzer (Ecom-AC,Germany), FT-IR(Nicolet, Magna-IR560), and GC-(Shimazu).The results of the experiment conducted to decompose and eliminate the harmful gas SO2with the Ca(OH)2catalysis reactor and SPCP reactor show 96% decomposition efficiency at the frequency of 10 kHz. Theconductivity of the standard gas increased at the frequencies higher than 20 kHz. There was a partial flow ofcurrent along the surface. As a result, the decomposition efficiency decreased.The decomposition efficiency of harmful gas SO2 by the Ca(OH)2 catalysis reactor and SPCP reactor was96.0% under 300 ppm concentration, 10 kHz frequency, and decomposition power of 20 W. It was 4% higherthan the application of the SPCP reactor alone. The highest decomposition efficiency, 98.0% was achieved atthe concentration of 100 ppm.
