Title
Bifunctional Pd/Al-SBA-15 catalyzed one-step hydrogenation–esterification of furfural and acetic acid: A model reaction for catalytic upgrading of bio-oil
Abstract

Al-SBA-15 supported palladium bifunctional catalysts were evaluated for one-step hydrogenation–esterification (OHE) of furfural and acetic acid as a model reaction for bio-oil upgrading. Experimental results show that it is viable to convert these unstable constituents of bio-oil to esters and alcohols through this simple and effective OHE reaction. The results of NH3–TPD and catalytic performances show that Al-SBA-15 with medium ratio of Si/Al favors the OHE reaction between furfural and acetic acid. It is noteworthy that there is a synergistic effect between the metal sites and the acid sites over composite bifunctional catalyst of 5%Pd/Al-SBA-15 for the OHE reaction.
