This study evaluated the catalytic activity of Mo catalysts derived from hydrotalcite-like compounds for steam reforming of toluene as a model compound for tar. The catalysts with 1.5, 3 and 4.5 Mo loadings (wt%), denoted as Mo 1.5 MgAl, Mo 3 MgAl and Mo 4.5 MgAl respectively, were prepared by coprecipitation and characterized by BET, XRD, SEM, TEM, FT-IR and UV–VIS. The results showed that toluene conversion increased with increasing molybdenum content. The hydrogen amount depended on two factors: the presence of molybdate species on the surface and the presence of aluminum cations in tetrahedral sites (Mo 3 MgAl), with molybdenum influence being more pronounced. The H 2 /CO ratio decreased at increasing temperature while, the H 2 /CO 2 ratio increased proportionally with temperature. Mo 1.5 MgAl catalyst was more selective for CO 2 and H 2 , while, Mo 3 MgAl and Mo 4.5 MgAl were more selective for CO and H 2 .
