摘要	The pyrolysis kinetics of three components of biomass (cellulose, xylan and lignin) with the addition of potassium and calcium were investigated by thermogravimetric analysis (TGA) and distributed activation energy model (DAEM). Results showed that the pyrolysis kinetic of cellulose, xylan and lignin followed Avrami-Erofeev-DAEM, Three-Gaussian-DAEM and Three-Gaussian-DAEM, respectively. These models can also be used to describe the pyrolysis kinetic of K-impregnated and Ca-impregnated components, and the goodness of fit (adjR(2)) of models was all greater than 0.99 (except for the sample of cellulose impregnated with 5%Ca2+). Based on the change of fitting parameters, it was found that potassium and calcium inhibited the conversion rate of cellulose and led to a wider temperature range and lower start temperature. Meanwhile, high impregnation ratio of calcium promoted the charring process of xylan and lignin, resulting in the production of more char. Furthermore, the prediction performance of models was verified that models can be used to predict the conversion curves at different heating rates. (C) 2021 Published by Elsevier Ltd.
