| Description: |
AbstractPyrolysis and liquefaction biocrudes obtained from lignocellulose are rich in phenolic compounds that can be converted to renewable aromatics. In this study, Pt catalysts on reducible metal oxide supports (Nb₂O₅, TiO₂), along with non‐reducible ZrO₂ as a reference, were investigated in the liquid‐phase hydrodeoxygenation (HDO) of 4‐propylphenol (350 °C, 20 bar H₂, organic solvent). The most active catalyst was Pt/Nb₂O₅, which led to the molar propylbenzene selectivity of 77%, and a yield of 75% (98% conversion). Reducible metal oxide supports provided an increased activity and selectivity to the aromatic product compared to ZrO₂, and the obtained results are among the best reported in liquid phase. The reusability of the spent catalysts was also studied. The spent Pt/Nb₂O₅ catalyst provided the lowest conversion, while the product distribution of the spent Pt/ZrO₂ catalyst changed towards oxygenates. The results highlight the potential of pyrolysis or liquefaction biocrudes as a source of aromatic chemicals. see all
