In this study, catalytic decomposition of chlorobenzene, a model compound of dioxin, was investigated. Catalysts made of a mesoporous material SBA-15 were used. The effect of Pt impregnation on the catalytic activity was evaluated. The catalysts were characterized using BET and NH₃-TPD. The catalytic activity for chlorobenzene removal reaction was shown to increase with the acid amount of catalysts. Addition of Pt to Al-SBA-15 was also shown to enhance the catalytic activity.

In this study, toluene catalytic oxidation was investigated using various metal components (Cu, Ce, Ni, La and Zr) supported on Used FCC zeolite for the application of the waste recycling and odor reduction. Among the metals, 5 wt% Cu/zeolite showed the best catalytic activity. 100 % conversion was achieved at 300℃ which was 50℃ lower than that of other metal components. As increasing the amount of doped Cu, the CuO was formed and the surface area and pore size were decreased. By the reduction treatment before toluene oxidation, the catalytic activity of the oxidation below 250℃ was improved. No decrease of conversion was observed during the continuos reaction at 300℃ for 48 h.
