The practice of catalytic liquefaction of biomass converts biomass resources using sulfuric acid as catalyst is not conducive to industrial production.In order to overcome this shortcomings,the liquefaction of corn stalk catalyzed by phosphotungstic acid in the reaction media of polyethylene glycol 400(PEG400) was studied.The effects of liquid concentration,reaction time,reaction temperature and catalyst dosage were investigated by single-factor test and orthogonal test.Results showed that liquefaction rate could reach 90.29% under the following conditions: temperature 180 ℃,reaction time 60 min,material/water concentration 0.15 g/mL and catalyst dosage 2%.At the same time,the IR spectra of corn stalk and liquefaction product were analyzed and compared,which showed that a large number of hydroxyl and esters were generated in the liquefaction.
