The characteristics of char-CO2 gasification were compared in the temperature range of 1,100–1,400°C using a thermogravimetric analyzer (TGA) for petroleum coke, coals and mixed fuels. The results showed that the reaction rate might increase with increasing gasification temperatures, and that the mixing of petroleum coke and coals has synergistic effects on fuels in response to reaction time and activation energy reduction. The volumetric reaction model could not adequately simulate the experimental data of mixed fuels, while the modified volumetric reaction model and shrinking core model matched the experimental data. As a result of the above, a reaction rate equation was suggested by selecting gas-solid reaction rate models for each sample that could simulate CO2 gasification behavior.
