The research on the mechanism of macromolecular cracking of low rank coal to produce hydrogen is of great significance to improve energy efficiency and transform coal into clean energy. At home and abroad, the coal pyrolysis process, influencing factors, molecular dynamics mechanism and hydrogen generation mechanism have been studied to varying degrees. However, there are few systematic studies on low-rank coal pyrolysis for hydrogen production from the perspectives of macromolecular structure composition, micro-component diversification, geological genesis and geological resources of low-rank coal. By analyzing the relevant research progress at home and abroad, I believe that attention should be paid to the mechanism of low-rank coal pyrolysis macromolecular cracking to produce hydrogen. In particular, the evolution law and mechanism of macromolecular structure of low-rank coal under the condition of hydrogen production. Clarify the macromolecular structure of coal, kinetics of hydrogen production, and hydrogen conversion pathways. This can provide key theoretical support for improving the efficiency and quality of hydrogen production.
