Interfacial control of CO2 and CH4 adsorption–diffusion in coal–mineral systems: Molecular insights for optimizing CO2-ECBM performance

Key Points

• Optimal adsorption of CO2 and CH4 occurs at the mineral interface, improving efficiency.
• Key findings indicate that interfacial properties significantly impact gas behavior in coal systems.
• Investigation employed molecular simulations to assess how minerals influence gas diffusion and adsorption.
• Discovering these interactions may lead to better CO2-enhanced coal bed methane recovery techniques.
