CO and CO2 Methanation over Promoted Nickel Catalysts Supported on Al@γ-Al2O3 |
| 초록 |
CO and CO2 methanation known as the Sabatier reaction have been studied to develop the better catalysts and related processes. Ni-based catalysts have been widely used in the commercial process. Besides, the support with a high thermal conductivity has its merit as long as the high dispersion of metal is guaranteed to prevent the sintering phenomena by highly exothermic methanation reaction. The metal-ceramic core-shell microarchitectures can be a solution to enhance the thermal conduction of a support and dispersion of metal particles. The outstanding catalytic performance of the Ni catalysts supported on core-shell metal-ceramic microstructures (Al@γ-Al2O3) on CO and CO2 methanation offers a new catalyst design strategy. Moreover, adding some kinds of promotors was also investigated to enhance the catalytic performances. Mn can be selected as the effective promoter to enhance the catalytic activity. This is closely related to the Ni dispersion determined by H2-chemisorption. On the other hand, the negative effect on CO methanation was observed over K-, Mg-, Zn-, and V-Ni/Al@γ-Al2O3. The negative effect on CO2 methanation was also found over V-Ni/Al@γ-Al2O3. |
