Abstract: With the gradual exhaustion of coal, oil, natural gas and other non-renewable resources and the worsening environment, the production of liquid fuels and organic chemicals through renewable biomass resources becomes more and more an important issue. In this study, with the ethanol as solvent and the dilute sulfuric acid as catalyst, the Salix psammophila, an abundant biomass resource in Inner Mongolia is used as the raw material of the alcoholysis liquid, and the effects of the solvent concentration, the reaction temperature, the dosage of Salix psammophila, and the dosage of catalyst on the liquefaction rate are investigated. Through the orthogonal experiment, the best liquefaction conditions are found: The solvent is ethanol, the ratio of liquid and solid is 60:1, the reaction temperature is 170℃, the sulfuric acid concentration is 0.06 mol/L, and the reaction time is 2 h. Under these conditions, the effect of liquefaction of Salix psammophila is the best and the liquefaction rate reaches 90.94%.
