文摘
- •
The heavier coal/char fractions had less vitrinite, exinite and more inertinite, leading to higher aromatization.
- •
The heavier char fraction presented higher gasification reactivity during the non-isothermal CO2 gasification in TGA.
- •
Amorphous carbon structure and exchangeable metal ion dominantly affect the isothermal CO2 gasification reactivity of char.
