摘要：
Much waste wood causing pollution and energy waste was produced in the processing of pinus massoniana wood. However, hemicellulose extracted from pinus massoniana waste can be transformed into bioenergy by means of pyrolysis, gasification, liquefaction, etc. Therefore, effects of deresination technology on extracting hemicellulose from Pinus massioniana were investigated by orthogonal and the whole factors test. The results show that 1) effects of deresinating temperature and time on quantity of dissolved resin is highly significant, but effects of deresinating pressure and volume fraction of degreasing agents on dissolved oleoresin volume are lightly significant. 2) Effects of deresinating temperature, time, pressure, volume fraction on removal volume of hemicellulose from pinus massioniana are lightly significant, removal volume of hemicellulose from deresinated wood is larger than that from untreated wood, but both increase in response to the increase of quantity of dissolved resin.
