高温水热处理对马尾松木材化学成分的影响
Effects of High Temperature Hydrothermal Treatment on Chemical Constituents of pinus massoniana
摘要
Abstract
The contents of cellulose,hemicellulose and acid insoluble lignin were determined by NREL. The chemical composition of pinus massoniana was analyzed under high temperature hydrothermal treatment. The results indicated that cellulose was decomposed at 160℃,the maximum decomposition of its content at 200℃.Hemicellu-loses were decomposed at 140℃ due to the poor thermal stability which caused by branching structure and amor-phous tissue. The content of acid insoluble lignin increased slightly with the prolongation of hydrolysis time. Tem-perature and time were significant factors affecting the content of 3 major elements in the high temperature hydro-thermal treatment,and the influence of temperature was more significant.关键词
