초록
본 연구에서는, Mn/TiO2 촉매를 이용하여 일산화질소의 산화반응 특성에 따른 연구가 수행되었다. TiO2의 물리 화학적 특징 및 활성금속인 Mn과 담체인 TiO2의 interaction에 따라 일산화질소의 산화반응이 서로 다르게 나타남을 관찰하였다. 우수한 NO oxidation 반응을 나타낸 Mn/TiO2(A)의 경우, Mn의 함량이 10 wt%에서 30 wt%로 증가할수록, 공간속도가 낮아질수록, 반응활성이 증가함을 확인하였다. 이러한 결과를 바탕으로 SCR 전단에 Mn/TiO2 촉매를 사용함으로써, fast-SCR을 유도하여 SCR반응활성이 증진될 수 있을 것으로 판단된다.
In this study, NO oxidation reaction using Mn/TiO2 catalysts was investigated. NO oxidation results revealed that the different trend was observed upon physicochemical properties of TiO2 and interactions between Mn and TiO2 support. Mn/TiO2(A) catalyst has a superior NO oxidation activity, which increased with decreased space velocity and increased Mn amounts from 10 to 30 wt%. The results indicated that the SCR activity could increase by the fast SCR reaction process using the Mn/TiO2(A) catalyst located in front of the SCR unit.
