Al-Ti Mixed Oxide Catalyst for Dechlorination of By-product of Methane Chlorination |
초록 |
In this study, Al-Ti mixed oxides are prepared by sol-gel method and they are used as catalysts for dechlorination of dichloromethane which is by-product of methane chlorination. The mixed oxides are characterized by X-ray diffraction, Brumaurer-Emmett-Teller analysis, NH3-temperature programed desorption and fourier transform infrared spectroscopy. The Al0.5Ti0.5Ox has abundant and stronger Lewis acid sites than Al2O3. Dechlorination of dichloromethane with Al0.5Ti0.5Ox catalyst has high dichloromethane conversion and chloromethane yield than Al2O3 under 360 °C. The result show that acidity of catalysts played important role in catalytic dechlorination of dichloromethane. Therefore, the Al-Ti mixed metal oxides increase efficiency of dechlorination and convert the dichloromethane to chloromethane, increase the overall efficiency of methane chlorination. |
