The influence of coal pyrolysis heating rate on char fragmentation propensity during secondary reactions

Key Points

• Char fragmentation propensity increases with higher heating rates in coal pyrolysis, indicating more intense thermal degradation.
• Analysis shows significant changes in char formation across varying heating rates, affecting overall efficiency.
• The study employs observational analysis of coal samples under different heating rates and secondary reaction conditions.
• Findings may enable enhanced coal utilization strategies, but further research is necessary to confirm broader applicability.
