    • A cellulose-containing biomass such as wood is liquefied by heat-treatment under a pressurized condition in the presence of water and a neutral, oxygen-containing organic liquid such as an ester, ether, ketone or alcohol. An alkaline catalyst such as potassium carbonate may be added to accelerate the liquefaction when the organic liquid is one other than acetone. Also provided is a process for the liquefaction of a cellulose-containing biomass including heat-treating the biomass in an aqueous medium in the pressurized atmosphere of an inert gas or steam at a temperature of 250.degree.-385.degree. C. in the presence of an alkaline catalyst in an amount of 0.01-0.1 part by weight per one part by weight of the biomass on the dry basis.
    • 在水和中性的含氧有机液体如酯,醚,酮或醇的存在下,在加压条件下通过热处理将木质纤维素生物质液化。 当有机液体与丙酮不同时,可以加入碱性催化剂如碳酸钾以加速液化。 还提供了一种用于液化含纤维素的生物质的方法,包括在惰性气体或蒸汽的加压气氛中在250-385℃的温度下在水性介质中热处理生物质, 碱性催化剂,其量为每干重1份(按重量计)生物量的0.01-0.1重量份。
