Abstract: | The Monte Carlo method in conjunction with the grand canonical ensemble was used to calculate the isotherms of adsorption of methane, nitrogen, and mixtures thereof in 1.34 × 3.02-nm rectangular-cross-section and 2.35 × 2.35-nm square pores in a lamellar carbon adsorbent. The phase diagrams of adsorbed methane were plotted, and the characteristics of the phases of the adsorbate were described. Modeling the adsorption of the binary mixture demonstrated that the square carbon pore is more selective with respect to methane. |
