Adsorption behavior of methane has been simulated by using the grand canonical ensemble Monte Carlo (GCEMC) method Methane is modeled as a spherical LJ molecule
and the 10 4 3 potential is used for the description of the interaction between methane and a slit pore in the GCEMC simulation To test our program
adsorption
desorption and capillary condensation are simulated at T =74 05 K The adsorption isotherm and local density profiles obtained are in good agreement with data from Jiang et al Then
the adsorption storage behavior of methane in various slit pores at T =300 K is simulated The adsorption isotherms and effective storage values changing with pressures and slit pore widths are presented The best slit width and reasonable adsorption pressures for the adsorption of methane at T =300 K are recommend
