Summary: | The invention discloses a method for preparing biomass liquefied oil by the catalytic liquefaction of the biomass, and relates to a method for preparing the bio-oil by the liquefaction of the biomass, which belongs to the field of chemical and industrial catalysis. The method for preparing the bio-oil comprises the steps as follows: arranging the biomass, solid acid and an aqueous solution containing C1-C3 monobasic alcohol in a pressure vessel; stirring and heating up the mixture to the temperature of 200 to 280 DEG C, with the pressure of 2 and 7MPa and the time of 0.5 to 10 hours; then cooling down the mixture to normal temperature and filtering the mixture; using C1-C3 halohydrocarbon to carry out extraction and refining to the obtained filtrate and filter residues respectively; combining the extracting and refining liquid and removing the halohydrocarbon and alcohol to prepare the biomass liquefied oil. Used independently as a technique for biological energy conversion, and with moderate conditions and y |
