A review of catalytic hydrodeoxygenation of lignin-derived phenols from biomass pyrolysis

► First review of the catalytic hydrodeoxygenation (HDO) of lignin-derived phenols. ► Review of the applied HDO catalysts. ► Review of reaction mechanism of HDO of lignin-derived phenols. ► Review of the kinetics of HDO of different lignin-derived model compounds. ► HDO-prospects and required further research and developments are discussed.
