Abstract

The ethanol-based pulping of Eucalyptus globulus by the ALCELL(R) process was studied to determine the optimum cooking conditions. In the first set of experiments the influence of chip size, chip impregnation,liquor-to-wood ratio and cooking additives was studied. Once the moreconvenient values for these variables were established according to kappa number, yield and viscosity, a surface response method was used to determine the influence of cooking temperature, cooking time and ethanol concentration on autocatalyzed pulping process. The developed models indicate that a high screened pulp yield (56%) and acceptable kappa number (23) and viscosity (1030 mL/g) can be obtained when cooking conditions are around 185 degrees C, 110 min and 50% of ethanol.
