| Abstract: | The CO2 gasification characteristics of three fly ash samples were performed by a temperature-programmed thermo-gravimetry.The results showed that heating rate had obvious effects on CO2 gasification reactivity,that the reactivity of SCFA higher than that of HLFA and NCFA.In general,the gasification reactivity of fly ash carbon was better than of the coal chars,and the reactivity of demineralized fly ash carbon was worse. |
