of polyurethane compounds was studied. The results show that giant reed biomass from metal-contaminated soil is potentially liquefied and significantly affected by solvent/solid ratio, liquefaction temperature and liquefaction time (P<0.05). The liquefaction rate of biomass in acidified ethylene glycol system can reach 85.2% with optimized conditions of 60 min, 170 °C, 3% sulfuric acid and solvent/biomass......
