Oraganosolv fractionation of eucalyptus was conducted in three types of organic acid (formic acid, acetic acid and their mixture). The pyrolysis behavior of its derived fractions were systematically studied. The solid residues from organosolv fractionation, namely cellulose-rich fraction, were characterized by elemental analysis, Fourier transform infrared spectroscopy (FT-IR) analysis, and thermogravimetric analyzer couple with mass spectrometry (TG-MS). Cellulose-rich fractions and organosolv lignins were subsequent fast pyrolyzed in Py-GC/MS to test the yield of desired molecules. The results demonstrated that organosolv fractionation could effective deconstruct of eucalyptus into xylose, organosolv lignin and cellulose-rich fraction. The yield and selectivity of levoglucosan and phenols from eucalyptus were obviously enhanced by organosolv fractionation, and the mixed acid exhibited the best performance.
Key words： organic acid; pretreatment; biomass; fast pyrolysis; levoglucosan
