Resumen:
Ethanol steam reforming was studied over Ni/MgAl2O4-CeO2 catalysts. The catalysts were prepared using different impregnation media: ethanol or water. The best catalytic behavior was found over the catalyst prepared from an ethanolic solution of Ni(NO3)2. This sample showed a high Ce3+/Ce4+ ratio, an adequate interaction Ni-support and an average Ni diameter around 28 nm. This catalyst was stable under the reforming conditions used in this work: initial ethanol concentration: 9.4%, reaction temperature: 650°C, W/F = 49 g min mol and reaction time: 40 h. The ethanol conversion was almost complete with H2 selectivity around 78%.
