Popis:	The thermal degradation behavior of naturally aging Chinese fir was investigated using a STA 449 thermal analyzer. The Chinese fir with different natural aging times showed different pyrolysis behaviors. The longer the natural aging time, the lower the initial pyrolysis temperature of Chinese fir. The results of activation energy estimated by Kissinger–Akahira–Sunose (KAS) method and Flynn–Wall–Ozawa (FWO) method are almost the same. However, with the increase in natural aging time, the activation energy of fir is increasing. The suitable pyrolysis reaction model of nature aging—10 Chinese fir was attributed to the ‘‘diffusion-Jander’’ (D3) model. Furthermore, a nth order reaction model serves for nature aging—70 and nature aging—100 Chinese fir reaction mechanism.
