Diffusion and sorption in zeolites-I. A Markov process formulation

A molecular model is used for describing diffusion and sorption of a single component in a one-dimensional pore. A state space is defined in terms of the occupancy of different sites of an individual pore. The process of diffusion and sorption is then formulated for the first time as a Markov process. This results in a system of simultaneous linear equations whose solution gives important insights into the process of diffusion and sorption in zeolites. The obtained using this novel procedure are shown to be consistent with earlier results. The Markov process formulation can be extended to cover more complex cases which will be treated in later parts of this series
