In recent years, the benefits of generating hydrogen from renewable sources and by means of processes with low energetic requirements have been investigated. In this context, oxygenated hydrocarbons coming from the biomass constitute a promissory source for sustainable hydrogen production by steam reforming and aqueous phase reforming (APR). The APR has several advantages over steam reforming for example the lower energy consumption since it avoids the vaporization of water and alcohol. Additionally, the lower APR temperature minimizes undesirable decomposition reactions and favors the water-gas shift reaction (WGS). Catalytic systems based on metals of group VIII are cited in bibliography for APR of oxygenated hydrocarbons, where the effect of different catalyst properties, such as metal particle size or support material, is not clear yet. The present contribution has as aim to analyze the effect of metal particle size and support, using Pt catalysts supported on Al2O3, SiO2, C, Al2O3 y Ce-Zr-Al2O3 in the APR of glycerol.
