The production of added value products following catalytic hydrogenation reactions of bioliquids was studied. These bioliquids were obtained from the pyrolysis of raw and acid-treated (H3PO4) Tall Fescue (Fescue arundinacea) waste. Before the pyrolytic test, the biomass samples were analyzed by a micro thermogravimetric 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 concentration, 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 to produce high added value alcohols.Key Words
