Eucalyptus globulus wood samples were treated at 120 or 130°C with 95% acetic acid solutions containing 0.2 or 0.4% HCl. At given reaction times, the composition of both solid residues and liquors were determined. For the various experimental conditions assayed, the time courses of unconverted hemicelluloses, sugar concentrations and furfural concentrations were measured. These variables were correlated...
Kinetic models were developed to give an interpretation of several phenomena involved in wood fractionation. Experimental data (obtained in wood treatments at normal boiling temperature with 95% acetic acid solutions containing 0 05-0 2% HCl), were used to develop kinetic equations for: (i) solid residue yield, (ii) solid residue composition (including lignin, cellulose and hemicelluloses) and...
