Experimental study of KCl concentration effects on coal pore structure and adsorption performance

Key Points

• Higher KCl concentrations enhanced coal pore structure, improving adsorption performance.
• Adsorption tests showed a 30% increase in efficiency at optimal KCl levels compared to lower concentrations.
• Experimental analysis of various KCl concentrations assessed their effects on coal samples' pore structures.
• Findings suggest that adjusting KCl concentration could maximize coal's adsorption capabilities, indicating practical applications.
