Active alkali charge, degree of delignification, degree of polymerizationAbstract
Delignification and depolymerization are great concerns in the cooking process. This research used eucalyptus and acacia mangium with active alkali charge of 16% to 20% and 1% variation. Active alkali charge influences the degree of delignification and degree of polymerization. Every 1% AA charge increase could increase the degree of delignification in eucalyptus and acacia mangium of 0.40 and 0.85% respectively. Every 1% AA increase can decrease DP in eucalyptus and acacia mangium of 3.32% and 7.04% respectively. Reduce of residual lignin on eucalyptus and acacia mangium of 0,4% and 0,7% respectively followed by increase of delignification degree by 1,9% and 3,0% respectively. The correlations between the delignification and polymerization degree in the eucalyptus and acacia mangium were y(e) = -119.74x + 12135 and y(a) = - 149.63x + 14716 respectively.
