木材热分解动力学的研究

用ＴＧ－ＤＴＡ热分析联用技术测定了４种常用木材的ＴＧ－ＤＴＡ－５曲线，并用热动力学方法处理的ＴＧ曲线，获得了相应动力学参数。发现各种木材在干燥阶段和煅烧阶段的热性质大致相似，而炭化阶段的热性质则因木材人化学组成不同而有较大差异。

THE THERMOKINETIC STUDY OF WOOD PYROLYSIS

TG-DTA-T curves of woods of four tree species were determined by TG-DTA simultaneousmethod,TG curves were treated by using thermokinetic method to obtain thermokinetic parameters.Itwas found that at drying and calcining steps the hot nature of different woods is similar but at the charringstage the hot nature is rather different owing to different chemical constitution of wood.
