CO₂ gasification reaction characteristics were investigated at 1,000, 1,200, and 1,400 ℃ by promptly supplying Kideco coal, ash-free coal, and residue coal samples to a high temperature reactor (thermogravimetric analyzer). The reactant CO₂ gas was supplied to the isothermally controlled thermogravimetric analyzer at 1,300 ml/min flow rate for continuous monitoring of the sample weight changes and the resulting product gas concentrations. The results at 1,000 ℃ showed that the major gas product was CO for the Kideco coal and the residue coal while extensive CH₄ formation was observed for the ash-free coal. Further increase of reaction temperature to 1,400 ℃ resulted in the maximum product gas concentrations of 44.2 vol% CO, 13.1 vol% H₂, and ppm level of CH₄ for the ash-free coal. The observed times for completion of CO₂ gasification reaction were 28 and 12 min at 1,200 and 1400 ℃, respectively, indicating faster CO₂ gasification and predominant formation of CO and H2 at 1,400 ℃. The morphology of the 1,000 ℃-gasified Kideco coal and residue coal was of grayish and angular chunks while the ash-free coal was of swollen lumps. After completion of the gasification reaction at 1,400 ℃, the Kideco-coal, ash-free coal, and the residue coal left only small amount of unreacted mass settled at the bottom of the crucible, indicating nearly complete gasification reaction. It was noteworthy that the ash-free coal left very little amount of unreacted mass at 1,400 ℃.
