Hydrodeoxygenation (HDO) is a key reaction in the upgrading\u00a0of\u00a0bio-oil to produce hydrocarbon fuels or high-value chemicals. Oxygen removal in bio-oil increases its calorific value, improve thermal and chemical stability, reduce corrosiveness, etc., making the upgraded biooil suitable as a fuel or blending fuel. However, the dependence on high-pressure hydrogen is a serious disadvantage, as it is an expensive resource whose use also poses safety concerns. In this scenario, we propose a pioneering route for\u00a0model\u00a0biomass\u00a0compounds\u00a0upgrading via H2-free\u00a0HDO. Herein we have developed multifunctional\u00a0catalysts\u00a0based on Ru and ceria supported on carbon able conduct the hydrodeoxygenation reaction using water as hydrogen source. We found that cerium oxide improves ruthenium metallic dispersion and the overall redox properties\u00a0of\u00a0the multicomponent system leading to enhanced catalytic performance. Along with the successful catalytic formulation we identify 300 degrees C as an optimal temperature validating the H2-free\u00a0HDO\u00a0route for bio-compounds\u00a0upgrading.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Biofuels upgrading gathering momentum in view\u00a0of\u00a0the gradual depletion\u00a0of\u00a0fossil fuels and the pursuit\u00a0of\u00a0renewable energy sources to mitigate global warming.
