<p>Obtaining accurate kinetic parameters for predicting pyrolysis, gasification and combustion of anthracite remains challenging due to oversimplified assumptions and mismatched heating rates. To address this, a Time-Resolved Particle Evolution Model coupled with drop tube furnace (DTF) experiments was developed. The DTF experiments were performed at temperatures over 1323–1523 K in 100% N₂, 100% CO₂ and 9.2% O₂ in N₂ atmosphere, during which solid samples at strategic furnace locations were collected. The Time-Resolved Particle Evolution Model was then established, within which the heat/mass transfer and chemical reactions were considered. Results showed that the activation energies (<i>E</i>_a) of pyrolysis, gasification and combustion of JCA based on experimental data at 1423 K were determined to be in the range of 131.2–151.6, 122.4–132.8 and 112–126 kJ&#xa0;mol⁻¹. Using these kinetic parameters as the inputs, the predicted unreacted fractions at 1323 and 1523 K had a maximum deviation of 8% in comparison with the experimental values. The heat and mass transfer behaviour during these thermal conversions of JCA was also obtained, which would provide a validated tool for predicting the behaviour of anthracite at high heating rates (&gt; 10⁴ K&#xa0;s⁻¹) and offer better comprehension of the kinetics parameters for process control.</p>
