| Abstract Scope |
This study investigates the reaction behavior of high-rank coal with different particle sizes in the coal gasification and ironmaking poly-generation process. The gasification and ironmaking poly-generation process is promising for achieving CO2 recycling and clean coal utilization. Thus, the CO2 gasification behavior of two kinds of high-rank coal was investigated by the isothermal thermogravimetric method. The pore structure, chemical structure, and ash composition were also systematically tested. The results show that the particle size significantly influences the CO2 gasification of high-rank coal. Smaller particle sizes exhibit enhanced reactivity and faster gasification kinetics due to increased surface area and improved accessibility to reactants. The chemical structure and ash can also affect the fuel gasification reactivity. The findings provide valuable insights into optimizing high-rank coal gasification to improve overall process performance and resource efficiency. |
