Two-component desorption from anisotropic pore networks.
Dynamic Monte Carlo simulations are performed to explore molecular desorption of a two-component mixture from a mode adsorbent of adsorbate-related anisotropy. The intrinsic dynamics of the adsorbent-adsorbate host-guest system is described by assuming a situation typical of a "molecular-traffic-control" system, where the hopping rates of the two components in two directions, perpendicular to each other, are identical, while for each component, perpendicular to that direction of preferential propagation, the hopping rates are reduced. The resulting desorption patterns are discussed in terms of the jump probabilities and are shown to approach the corresponding analytical solutions in the limiting cases of isotropic and unidirectional diffusions.
