초록
논문은 유전체 볼 충진 배리어 방전 리액터를 이용하여 오존 생성 및 TCE 분해 특성에 대하여 논하였다. 오존 발생량은Al2O3 또는 TiO2 유전체 볼을 충진한 경우가 유전체 볼을 충진하지 않은 배리어 방전리액터에 비하여 크게 증가됨을 보였으며, 이러한 방전구조는 오존 생성량을 증가시키기에 적절한 것으로 판단되었다. 또한, TCE 분해효율과 COx 전환율은 MnO2충진 방전리액터를 사용한 경우가 높았으며, 이것은 방전공간에 위치한 촉매 표면에서 오존 분해에 따른 화학반응에 기인된것으로 파악되었다. 촉매 표면 화학반응을 파악하기 위하여 Al2O3 유전체 볼 충진 방전리액터와 촉매 리액터를 직렬로 배치하여 TCE 분해 효율이 100[%]에 도달하였음을 확인하였으며, MnO2 촉매는 오존 분해에 매우 좋은 재료이며, 이러한 오존분해 촉매 반응을 이용하여 TCE와 같은 VOCs 분해에 유용하게 활용될 것으로 사료된다.
Abstract
This work was carried out ozone generation and TCE decomposition characteristics using dielectric ball materialsfilled barrier discharge reactor and catalyst’s reactor for ozone decomposition. Ozone concentration generated fromAl2O3 or TiO2 filled barrier discharge reactor was so high compared with non-filled discharge reactor. This reactor isgood discharge structure for generating the high ozone concentration. In addition, TCE decomposition rate and COxconversion rate increased using MnO2 filled discharge reactor, because ozone was decomposed at the same dischargespace on the surface of MnO2 catalysts. To identify the MnO2 catalytic effects, TCE decomposition rate reached to100[%] by the decomposition of ozone at MnO2 catalyst’s reactor by the arrangement of Al2O3 filled discharge reactorand MnO2 catalyst reactor. Finally, MnO2 catalyst is good materials for the decomposition of ozone and this processwill be useful for decomposing VOCs such as TCE.
