Figure 6
The schematic representation of adsorbed and free gas phases for methane adsorption in illite nanopore of \(W=4\) nm at 333.15 K and 50 MPa. The heights of adsorbed and free gas phases are depicted from \({\rho }_{a}={\int }_{A}^{B}\rho (z)dz/{z}_{AB}\) and \({\rho }_{b}\) from NIST Chemistry Webbook, respectively.
