Abstract: TG was used to study the thermogravimetric behavior of Fushun oil shale at different heating rates in argon atmosphere. Four thermal kinetic models, DAEM model, Coats⁃Redfern method, FWO method and Doyle method, were compared and analyzed. The results show that the results of different dynamic model analysis are different: Coats⁃Redfern method, activation energy (E) has little change, and E belongs to the average value in a certain temperature range, which increases with the increase of heating rates as a whole. E is 109.40 kJ/mol when the heating rate is 20 ℃/min. The E of the DAEM model, the Doyle method, and the FWO method all increase with the increase of conversion rate. In addition, the E obtained by the DAEM model and the FWO method are relatively close, the DAEM model has the highest coefficient of determination. Therefore, the DAEM model is the most suitable for the kinetic analysis of Fushun oil shale pyrolysis among four thermodynamic analysis methods.
