Catalytic Behavior of Ga Supported on Mesoporous TiO2 Catalysts for The Dehydrogenation of Ethane to Ethylene |
초록 |
Mesoporous titania (m-TiO2) was synthesized by a facile hydrothermal method. The Ga supported on m-TiO2 catalysts (Ga/m-TiO2) were prepared by the in situ hydrothermal method and the impregnation method with a Ga loading varying in the range of 5-20 wt.%. The catalytic performance of Ga/m-TiO2 catalysts was tested in the dehydrogenation of ethane (C2H6). The C2H6 conversion and the C2H4 selectivity drastically changed depending on the reaction temperature, the Ga loading and the catalyst preparation method. The conversion increased with raising the temperature up to 600 ºC. Among these catalysts, 10 wt.% Ga/m-TiO2 exhibited the highest C2H6 conversion and C2H4 selectivity. The Ga/m-TiO2 catalysts prepared by the in situ hydrothermal method showed better catalytic performance than Ga/m-TiO2 catalysts prepared by the impregnation method. It can be due to the well dispersion of the small Ga species in the mesopores of m-TiO2 during the hydrothermal treatment process. The Ga/m-TiO2 catalysts possessed the superior conversion in compare to Ga supported on bulk TiO2, which comes from the high surface area and high pore volume of m-TiO2. |
