The production of added value products following catalytic hydrogenation reactions of bioliquids was studied. These bioliquids were obtained from pyrolysis of Tall Fescue (fescue) waste. Fescue is an abundant gramminea usually employed for forage in the province of Buenos Aires, Argentina. It generates great volume of waste. The bioliquids were obtained from the pyrolysis of fescue and fescue washed with phosphoric acid. Previous to the pyrolysis, the biomass samples were analyzed with a microthermogravimetric analysis coupled with FTIR spectroscopy (TGA-IR), which enables the chemical identification of functional groups of gaseous molecules originated by solid/gas transformations. From these results, the pyrolysis temperature was selected, and bench scale pyrolysis reactions were carried out. The pyrolysis bioliquids showed high furfural concentrations, with values of 46 and 70% for fescue and acid washed fescue, respectively. The bioliquid with the highest furfural concentration was catalytically hydrogenated in aqueous phase. A batch reactor was employed, with Ru/C and Ru-Sn/C catalysts for the production of high added value alcohols.
