The Effect of Demineralization on Coal Functional Group Pyrolysis: Rank‐Dependent Dual Mechanisms of Structural Reorganization and Mineral Catalysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=
