摘　　要：生物质液化技术可将低品位的固体生物质转化成高品位的液体燃料或化学品,是生物质高效利用的主要方式。首先分析了不同生物质组分液化过程中的机理,在此基础上,以木质生物质液化溶剂的选择为出发点,讨论了水、醇类以及混合溶剂作用下的液化反应,同时比较了催化剂对液化过程及产品组成的影响,指出醇类溶剂液化在液化油产品质量、液化过程分子结构的调控方面具有较大的优势,在高品质液化油、燃油添加剂合成等方面具有较高的应用前景。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.
