Popis: | Molecular simulations of CH4/CO2 competitive adsorption in moisture coals are carried out. The synergistic effect of micropore walls has a significant impact on the spatial distribution of adsorbates. Water molecules in micropores can prevent CO2 and CH4 from smoothly diffusing and adsorbing in the pore. The micropore is more favorable to the advantage of CO2 in the competitive adsorption. The variation of excess adsorption capacity is related to the density difference between adsorbed phase and free phase. Relative to CH4 density, CO2 density is easier to affect the variation trend of adsorption capacity in the competitive adsorption. |
