摘要：
The potential of pre-extracting hemicelluloses from aspen chips before mechanical pulping was investigated in this study. The effects of three independent process variables (NaOH charge, pre-extraction temperature and time) on three dependent variables ('pulping' yield, xylan extraction yield, and cellulose content in 'pulps') were studied using Box-Behnken experimental design. Mathematical model of xylan extraction yield was obtained and verified. It was found that NaOH charge, time, interaction between NaOH charge and time as well as interaction between temperature and time have significant effects on xylan extraction yield. The xylan extraction yield was 22.6%, i.e., about 37.20kg of xylan could be extracted from one ton of oven-dried aspen chips under the conditions of 5.68% NaOH, 100 degrees C and 35min.
