Understanding the mechanisms governing coal pyrolysis reactions, particularly in relation to macromolecular structure, is crucial for improving energy efficiency and facilitating transition of into a clean source. This study employs cutting-edge techniques, such as High-Resolution Transmission Electron Microscopy (HRTEM) Thermogravimetric Analysis coupled with Fourier Transform Infrared Spectroscopy Mass Spectrometry (TG–FTIR–MS), analyze lignite its residual solid samples subjected across range temperatures from 300 °C 1100 °C. The variational characteristics structure during are examined. Utilizing molecular dynamics simulations, we evolution mechanism carbon organic matter process. results show that can be divided three distinct phases: activation (30–300 °C), (300–650 condensation (650–1200 °C). During these phases, undergoes complex transformations, including folding, twisting, shedding small side chains, breaking ultimately leading directional arrangement structural fragments. units initially undergo decomposition, followed by growth alignment certain direction. spatial distribution aromatic evolves local ordering complete disordering, culminating larger-scale, three-dimensional ordering. order bond within is: oxygen-containing functional groups (such C–O COOH) > aliphatic (N–C C–C) (CC). By uncovering reaction intermediates pathways involved pyrolysis, this research provides comprehensive quantitative description These insights offer invaluable theoretical support industrial-scale coal, paving way more efficient sustainable utilization resource.
