The importance of indoor air environment gets higher because time of staying in indoor such as house or car become longer due to a change of the life pattern on human society. One of major pollution sources, VOCs or odor could be reduced or controlled by using adsorbent. It may be valuable for used catalyst to be applied in the adsorption of VOCs or odor. This could reduce the cost of adsorbent. In this work, the potential of used zeolites such as HZSM-5 catalyst and FCC catalyst as an adsorbent for removing acetaldehyde was investigated. Their adsorptive performances were compared with those of active carbon and MCM-41. The removal performace of used HZSM-5 was similar to that of active carbon due to its higher surface area. But used-FCC catalyst showed the lowest performance. These results suggest that used HZSM-5 can be applied to cheap adsorbent for acetaldehyde removal.
