DEVELOPMENT OF MATHEMATICAL MODELS FOR DESCRIBING ORGANOSOLV PULPING KINETICS OF FUNGALLY PRETREATED WOOD SAMPLES

摘要

Eucalyptus grandis wood samples decayed by white- and brown-rot fungi were cooked at 180 deg. C for 5 to 100 min with methanol/water (78:22 v/v) containing 25 mM of CaCl_2 and 25 mM MgSO_4. Mathematical models for describing organosolv pulping kinetics of the fungally pretreated samples were developed to estimate delignification constants, and also rate constants for xylan and wood mass solubilization.
