Resumen:
Actually, the use of biomass as feedstock for the production of fuel, energy and chemicals represents one of the future technologies that can help reduce global warming and reduce dependence on fossil fuels. Specifically, cellulose is one of the most abundant components of biomass and, therefore, represents one of the promising materials in selective hydrolytic processes to generate fuels and chemicals of high added value [1].Here, supercritical water (SWC) is recognized to possess good ability to depolymerize cellulose. Although more than 96% of the cellulose is solubilized, the presence of oligomers remains high (> 60% C) [2]. A possible mechanism to solve this problem is complete the hydrolysis of cellulose using heterogeneous acid catalysts (sulfonated mesoporous silica, sulfated zirconia, sulfonated activated carbon) [3]. Furthermore, Fukuoka and Dhepe [4] and Luo et al. [5] reported heterogeneous catalytic processes for the conversion of cellulose to sugars and microcrystalline alcohols, by combining hydrolysis hydrogenation over supported noble metal catalysts, such as Pt / Al2O3 and Ru/C [6]. Therefore, parameters such as porosity, specific area, active phase and the acidity of the catalysts are key factors in the development of these processes.Microporous materials (pore diameter
