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.
