초록

본 연구에서는, 실제 $150000Nm^3/hr$ 규모의 연소로에서 운전된 $VO_x/TiO_2$ SCR 촉매의 활성저하 원인을 규명하고자 XRD, BET, AES ICP, $H_2$-TPR, $NH_3$-TPD 분석을 수행하였다. $TiO_2$의 상전이 및 $VO_x$의 결정화가 발생하지 않았기 때문에 열에 의한 촉매의 활성저하는 없는 것으로 나타났다. 반면, 성분 분석결과 S의 함량이 검출되지 않고 Ca이 다량 검출됨에 따라 $SO_2$에 의한 피독이 아닌 Ca에 의한 피독이 발생하였음을 확인하였으며 이러한 Ca의 피독은 $NH_3$의 흡착량을 감소시켜 반응활성을 감소시키는 것으로 나타났다.
