Research Progress of Hydrodeoxygenation of Lignin-Derived Phenolic Compounds on Metal-Supported Catalysts to Prepare Liquid Fuels
Lignin-derived phenolic compounds in biomass suffer from disadvantages such as high oxygen content and poor stability.The hydrodeoxygenation upgrade can prepare high-quality liquid biofuels,which has important practical significance for realizing the carbon peaking and carbon neutrality goal.This paper reviews the metal-supported catalysts used in the hydrodeoxygenation of lignin-derived phenolic compounds in recent years.Firstly,the effects of intermetallic synergies on the performance of hydrodeoxygenation reaction are analyzed based on the perspective of monometallic and bimetallic components.Subsequently,considering the effect of metal site characteristics on hydrodeoxygenation reaction,the metal size,metal dispersion,and catalytic activity of single atom metal catalyst are discussed,and the influencing factors of metal site characteristics and the mechanism of effect on hydrodeoxygenation reaction are expounded.Following that,based on the influence of the carrier on the metal site,the correlation factors between the carrier characteristics and the metal site characteristics are discussed,and the influence mechanism of the carrier on the metal active site is revealed.Finally,the development direction of metal-supported catalysts is prospected.
