In the present work, Ni and Co supported over MgAl2O4 modified with Pr have been prepared by the wet impregnation method with 8 wt.% Ni (Co) and variable loadings of Pr (3 and 8 wt.%). The samples were characterized by XRD, BET area, TPR and TPO and they were tested in the ethanol steam reforming reaction. Under reactive conditions, the four systems were very active. The nickel-based catalysts showed a high activity for C-C bond cleavage and consequently a high amount of carbon. Cobalt-based catalysts promoted the formation of acetaldehyde and less graphitic and more reactive carbon deposits were detected.
