Abstract

The pyrolysis characteristics of acetylated wood flour(AWF)were studied at different heating rates(5, 10, 15, 20 and 25 K/min)by thermogravimetric analysis, and the pyrolysis kinetics was studied by Horowitz-Metzger and Coats-Redlfern.The result showed that the pyrolysis process of AWF included pre-pyrolysis, fast pyrolysis and slow pyrolysis. The percentage of loss weight of AWF at fast pyrolysis stage reached 70%. The experiment data regressed by two different models illuminated the fast pyrolysis process was a first-order reaction. Activation energy values calculated by each model were different, but the overall trend was almost the same. It was showed that AWF decomposed less than some other biomass materials by contrasting their pyrolysis parameters.
