The adsorption of a gas in a microporous solid is a matter of transfer with a movement quantity from one environment to another. This property is probably a transport phenomenon. In this case, the best mathematical model used to describe it is Fick's law.We propose a new theoretical expression of simulation of a gas in a microporous solid in order to find a better correlation with the experimental. In this paper, we underscore the importance of the physical kinetics of gas adsorption by a microporous solid. Using a good choice of pairs, we have determined the minimal distance from which the interaction forces adsorbate-adsorbent orients the adsorbate molecule to the adsorbent as well as the existence of a critical temperature and its effect on the relaxation time relative to the adsorbed matter quantity. KEY WORDS: Kinetic, adsorption, diffusion, microporous solid
