Abstract: Biomass liquefaction technology can convert low-grade solid biomass into high-grade liquid fuel or chemicals, which is the main way of efficient utilization of biomass. Firstly, the mechanism of liquefaction of different biomass components was analysed. On the basis of this, the liquefaction reactions with water, alcohols and mixed solvents as liquefaction solvent were discussed. Then,the influences of catalyst on liquefaction process and product composition were analyzed and compared. The great advantages of alcohols in the quality of liquefied oil and the molecular structure of the liquefaction process were pointed out, and it has high application prospect in high quality liquefied oil, fuel additive synthesis and so on.

Key words: lignocellulose biomass, liquefaction, bio-oil, solvents
