摘要	The co-pyrolysis kinetics of a binary system of cellulose, xylan and lignin was investigated by means of a thermogravimetric analyzer based on distributed activation energy model (DAEM). Synergistic effects were found in the co-pyrolysis of the binary system, resulting in a shift toward lower decomposition temperature and different decomposition rate. In terms of the kinetic mechanism, the results showed that the fitting performance of double-Gaussian-DAEM (DG-DAEM) was poor for the conversion rate curves and that the weighting factor cannot accurately reflect the reaction contribution of components in the binary system. Then, the predictions of three-Gaussian-DAEM (TG-DAEM) were well matched to the experimental curves, indicating that TG-DAEM was more suitable than DG-DAEM for describing the co-pyrolysis process of a binary system. The weighting factors in TG-DAEM represented the reaction contribution of each decomposition stage in the co-pyrolysis process, which was consistent with each peak in the DTG profiles. Excellent prediction performance was verified for TG-DAEM to predict the thermal behaviors at different heating rates.
