Abstract: Hydrodeoxygenation(HDO) process of phenolic compound is an important process for upgrading and refining bio-oil to high value-added chemicals and high-quality liquid fuel, in which the catalyst plays a vital role. Research on the catalytic process of hydrodeoxygenation of bio-oil model compound phenols has important reference significance for bio-oil upgrading and refining. Phenolic compound hydrodeoxygenation catalysts mainly include precious metal catalysts, non-precious metal catalysts and bimetallic catalysts. This paper summarized the advantages and disadvantages of various catalysts, and briefly described the mechanism of various catalysts in the process of phenol hydrodeoxygenation. And the catalyst was evaluated for substrate conversion, product selectivity, and catalyst stability.
