The aim of this work is to study the catalytic activity of Ni(10%) based catalysts supported over γ-Al2O3 modified with Mg (3%) for the steam reforming of glycerol. Catalysts have been prepared by incipient wetness impregnation method; analysing the effect of the calcination temperature of the modified support and the calcination temperature of the catalysts. Catalysts were characterized by temperature programmed reduction, (TPR), x-ray diffraction (DRX) and BET surface area. All catalysts were tested for this reaction in a fixed bed reactor. The best performance was achieved with the catalyst calcined at 500°C being the optimum calcination temperature for the modified support of 900°C This behaviour is ascribable to the formation of MgAl2O4 spinel which favours the dispersion of Ni°, responsible of the catalytic activity.
