In the present study, thermal decomposition kinetics of chitosan was investigated by a thermal analyzer. Firstly, the experiments were performed at three different heating rates from 30 °C to 800°C under inert atmosphere. The results showed that heating rates significantly affected the maximum peak temperatures but it did not affect the conversion. When the heating rates increased, the maximum peak temperatures shifted towards the higher temperature region. In the second part, TG kinetic data was used to calculate the activation energies based on Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), Starink and Tang kinetic models. All models used provided accurate fits of experimental data and yielded acceptable errors. The values of the average activation energy for FWO, KAS, Starink and Tang models were determined to be 148.5, 146.4, 148.3 and 146.7 kJ/mol, respectively.
