| Abstract:The combined pretreatment of oxygen and ionic liquid-［Emim］Ac to improve the enzymatic hydrolysis efficiency of wheat straw was investigated in this paper. Results showed that the optimal conditions were: ratio of solid to liquid 1∶1.5, oxygen pressure 0.4 MPa, temperature 130 ℃ and treatment time 6 h. Under such conditions, the reducing sugar yield of 65.1% was obtained at cellulase dosage of 30 U/g and enzymatic hydrolysis time 72 h, which was 5 times higher than the unpretreated raw material. Characterization of the treated wheat straw by SEM, XRD and FT-IR analysis showed that its surface became rough and porous, and the crystallinity decreased by 12.6%. |
