We investigate kinetic selectivity effects that take place during the adsorption of a binary mixture inside a nanotube and on the external surface of a bundle. By using a kinetic Monte Carlo Scheme we allow adsorption on sites with different binding energy (external surface) and we restrict adsorption/desorption only to the end sites in the case of the internal adsorption. In both cases, we analyze the appearance of an overshoot in the fractional coverage of the weaker species (before equilibrium) observed previously for a single, homogeneous, one-dimensional chain. \newline
