Valorization of the Aqueous Fraction of Pyrolysis Bio-Oil Via Catalytic Hydrogenation to Sorbitol
Short Introductive summary
This work investigated the direct valorization of the aqueous fraction of fast-pyrolysis bio-oil, which is rich in levoglucosan. Levoglucosan is a key precursor for sorbitol production. Direct hydrogenation of this aqueous phase offers a route to upgrade a carbohydrate-rich bio-oil fraction that is otherwise difficult to integrate into conventional biorefinery schemes. The results showed that the reaction medium strongly influenced product distribution, with aqueous conditions favoring sorbitol formation, while temperature and reaction severity affected selectivity. Overall, the work highlights the aqueous bio-oil fraction as a renewable feedstock for higher-value chemicals rather than a low-value stream.
