Based on the calculation of surface free energy change and isosteric heat of adsorption,affinity of coal with CO2 and adsorption capacity differences of coal for CO2 and CH4 were theoretically investigated by using the isothermal adsorption test data at 25,30 and 40 ℃ conditions.Compared to adsorption of CH4 and CO2 on coal matrix generally gave rise to more surface free energy change of coal,implying the thermodynamics of coal matrix have more adsorption capacity of CO2 than that of CH4 per… CONTINUE READING
