摘要：NOVELTY - The method for preparing biological oil by utilizing biomass liquefications. The method includes the following main steps: placing biomass, catalyst and aqueous solution of monohydric alcohol of C1-C3 into a pressure-resisting container with stirring device, in the presence of inert gas stirring for 50-70 min, heating to 230-310 deg.C and pressurizing to 8-15 MPa, retaining said state for 10-60 min., cooling and regulating pH value of the obtained material to 1-3, then filtering, using halohydrocarbon of C1-C4 to respectively extract the obtained filtrate and filter residue, combining extracts and removing halohydrocarbon so as to obtain biomass liquefied oil.
