Abstract

The porous ceramic beads using mine tailing were prepared and applied to catalytic converter for NOx/SOx removal. Catalytic support was used synthesized mesoporous silica (SBA-15) which coated on surface. Internal structure for porous ceramic beads was composed of three-dimensional network structure and porosity was about 80%. In addition, the specific surface area for mesoporous silica(SBA-15) coated on converter was significantly increased 55 $m^2/g$ compared with 0.8 $m^2/g$ before coating. NOx/SOx removal experiment was performed using $V_2O_5$ and $V_2O_5$/CuO converter. NOx conversion ratio for $V_2O_5$/CuO converter was approximately increased 10% compared to $V_2O_5$ converter. In addition, catalytic converter of $V_2O_5$/CuO was shown to remove 95% of NOx and 90% of SOx at reaction temperature of $350^{\circ}C$, space velocity of 10000 $h^{-1}$ and $O_2$ concentrations of 5%, respectively.

광미를 이용하여 다공성 세라믹 비드를 제조한 후 NOx/SOx 제거용 촉매 변환기로 응용하였다. 변환기 표면에 코팅처리된 촉매 지지체는 합성한 메조포러스 실리카(SBA-15)를 사용하였다. 다공성 세라믹 변환기의 내부 구조는 기공과 기공이 서로 연결되어 있는 3차원 망상구조이며 기공율은 80%로 나타났다. 또한, 촉매 변환기의 비표면적은 SBA-15 코팅 전 0.8 $m^2/g$에서 코팅처리 후에는 55 $m^2/g$으로 크게 증가하였다. NOx/SOx 제거 실험은 다공성 세라믹 촉매 변환기 표면에 $V_2O_5$와 $V_2O_5$, CuO를 함께 담지한 것으로 실시하였다. NOx 전환율은 $V_2O_5$/CuO 변환기가 $V_2O_5$ 변환기에 비해 약 10% 정도 높게 나타났다. 또한, $V_2O_5$/CuO 변환기는 반응온도 $350^{\circ}C$, 공간속도 10000 $h^{-1}$, 산소농도 5%에서 NOx 95%, SOx 90% 이상의 전환율을 각각 나타냈다.
