Abstract

In this work, the feasibility of spent zeolite catalyst for reusing as a support was investigated in catalytic odor removal reaction. As a model reaction for odor removal, toluene was selected as a reactant. 10wt% Cu was impregnated on spent HZSM-5 catalyst and spent FCC catalyst. The catalytic activity of the spent HZSM-S was higher than that of spent FCC catalyst in toluene oxidation. This was due to the fact that the surface area of spent HZSM-S was higher than that of spent FCC catalyst. These results may suggest that spent HZSM-S can be reused as a cheap catalyst for toluene removal.

본 연구에서는, 촉매 악취 제거 반응에서 폐제올라이트 촉매를 담체로 재사용할 수 있는지를 알아보고자 하였다. 악취 분해의 모델 반응을 위하여 톨루엔을 반응 물질로 선정하였다. 폐 HZSM-5와 폐 FCC촉매에 구리를 10 wt%담지 시켜, 활성을 비교하였다. 그 결과, Cu/폐 FCC 촉매보다 Cu/폐 HZSM-5가 더 높은 활성을 나타내었다. 이는 폐 HZSM-5가 폐 FCC 촉매보다 표면적이 더 크고, Cu를 담지한 촉매에서도 더 큰 표면적을 나타낸 것에 기인한 것으로 여겨진다. 이러한 결과들은 폐 HZSM-5가 톨루엔 제거에 값싼 촉매로 이용될 수 있음을 보여준다.
