Adsorption equilibration processes inside narrow pores

Initially motivated by experimental results concerning gas adsorption in open-ended carbon nanotubes, we investigate the adsorption kinetics of a gas inside a nanopore by implementing a Kinetic Monte Carlo simulation of the gas dynamics. In addition to obtaining the change in coverage with time, we analyze the spatial configuration of the adsorbed phase inside the pore as it evolves towards equilibrium. We also identify blockage events near the ends of the pore, and determine the dependence of these processes on the length of the pore and the amount of gas adsorbed.
