Resumen:
Sunflower seed hulls are abundant lignocellulosic residues of the edible oil industry in the south region of Buenos Aires, Argentina, where 22 thousand tons are accumulated per year. This material could be considering as a source of biomass for carrying out pyrolysis processes for Value Added Products (VAP) production. With our continuing interest in valorizing sunflower seed hulls, the production of furfuryl alcohol from this residue is analyzed. In pursuing this, in a first step a bio-oil rich in furfural is obtained from the pyrolysis of the hulls. Secondly, this bio-oil is submitted to a catalytic treatment for converting furfural into furfuryl Alcohol, employing a Pd based catalysts in a Batch reactor under mild conditions (at 110°C and 0.4 MPa of H 2 ). The Pd based catalysts, Pd/BCs, are prepared by supporting palladium on bio-chars (a co-product of pyrolysis of the hulls). The conversion of furfural and the selectivity to furfuryl alcohol are analyzed for the different catalysts, in the context of the evaluation of the possibility of producing VAP from the hulls.
