광촉매와 코로나방전 조합을 이용한 아세트 알데하이드의 분해

초록

Photocatalyst and corona discharge technique with low energy are used to remove voletile organic compounds or stink materials. In order to obtain higher decomposition efficiency, the decomposition efficiency of acetaldehyde was investigated by three-type of techniques using photocatalyst, corona discharge and photocatalyst combined with corona discharge. Decomposition reaction was carried out at room temperature with different concentration of acetaldehyde and consumption power. All of reactions showed totally good decomposition efficiency with higher concentration and consumption power. Especially, photocatalyst combined with corona discharge showed remarkable decomposition efficiency than another techniques for high concentration(4000ppm) in case of similar consumption power(UV-lamp 18W, corona discharge 16W).
