Bio-oils from fast pyrolysis of lignocellulosic biomass are composed of a variety of aromatic compounds. Such aromatic carbon compounds from non-fossil resources are considered promising value-added biofuels and industrial chemicals, which can help to reduce the use of fossil fuels. However, high oxygen contents in bio-oils result in relatively lower heating efficiency in comparison to conventional fuels. In addition, undesirable features of bio-oils such as poor stability, high acidity, and impurities are indeed problematic to directly use them in current internal combustion engines. Therefore, it is suitable to remove the oxygen containing functional groups of bio-oils to produce high efficiency biofuels. Other applications of bio-oils rely on their valorization through different processes. Catalytic hydrodeoxygenation (HDO) of biomass-derived oxygenates has been considered a promising measure to control oxygen to carbon ratio in line with alteration of their functional groups. This chapter represents the developments and challenges of catalytic HDO of lignin-derived compounds.
