摘要

Abstract

The pyrolysis reactions of poplar particleboards were carried out using the thermogravimetric apparatus,The TG and DTG curves were used to analysis the pyrolysis mechanism by Coats-Redfern method. The results show that the non-isothermal pyrolysis of poplar particleboards can be generally divided into three stages:dehydration,fast pyrolysis and slow pyrolysis. As the heating rate increased,the maximum rate of weight loss were also increased. It was found that there was a lateral shift in the TGA curves to higher temperatures. The fast pyrolysis stage can be described by the model of D3. The activation energy is 107.24kJ/mol,and the pre-exponpential factors of 5,10 and 20 ℃/min are 2.09 × 105 s,6.57 × 105,3.22 × 105 s-1 ,respectively.
