Mechanism of adsorption in nanometric cylindrical pores has been analysed. Grand canonical Monte Carlo simulations were performed for two model systems: krypton and argon, adsorbed in an ideal (smooth) cylindrical silica pore of diameter 2R = 4 nm. The role of interatomic (adsorbate-adsorbate) interactions and atom-wall (adsorbate-adsorbent) forces in the mechanism of adsorption has been discussed. It has been shown that the correlation between these two energy components plays a crucial role in layering and capillary condensation transitions. The stability of different stages of adsorption has been analysed and discussed taking into consideration fluctuations of energy and number of adsorbed atoms during simulations.
