Fecha de publicación: | jul-2010 | Editor: | Elsevier | Citación: | Fuel Processing Technology 91(7): 765–769 (2010) | Resumen: | [EN] A series of carbon-based nickel (Ni) catalysts was prepared in order to investigate the effect of the preparation method on the dispersion of Ni and its final catalytic activity in the dry reforming of methane, i.e. CH4 + CO2 = 2H2 + 2CO. Three parameters were studied: (i) the influence of the surface chemistry of the carbon used as support; (ii) the method of drying (conventional vs. microwave drying); and, (iii) the temperature of the reduction stage. In order to study the role of the surface chemistry of the commercial activated carbon used as support, the active carbon was tested as received and oxidized. Although a better Ni dispersion was achieved over the oxidized support, the conversions were much lower. It was also found that microwave drying offers various advantages over conventional drying, the main one being that less time is required to prepare the catalyst. Two reduction temperatures were used (300 and 500 °C), being found that it is necessary to adjust this parameter to prevent the Ni particles from sintering. | Versión del editor: | http://dx.doi.org/10.1016/j.fuproc.2010.02.011 | URI: | http://hdl.handle.net/10261/78200 | DOI: | 10.1016/j.fuproc.2010.02.011 | ISSN: | 0378-3820 |
