摘      要：A comprehensive model for the kraft pulping kinetics of Eucalyptus saligna hardwood is presented. Kinetic parameters were estimated by fitting the model to available experimental data taken from the literature over a range of process variables. The model takes into account the effect of hydroxide and sulfide concentration in the liquor as well as the temperature-time history of the cooking. Model predictions were successfully compared with an independent set of bench-scale plant data for lignin and carbohydrate dissolution. The model is able to predict quite well the trends of the process variables.
