In isothermal equilibrium adsorption the deformation of micro porous carbon ad-sorbent at adsorption is characterized by the processes of compression and expansion of the adsorbent. Taking into account the deformation of adsorbents in the adsorption processes are extremely important at building a rigorous theory of the equilibrium adsorption and for the practical use of adsorbents. For example, the adsorption defor-mation can be a factor in reducing the rate of aging of adsorbents, which is especially im-portant in swing modes, adsorption and desorption. The work presents a thermodynamic analysis of the adsorption deformation of the isotropic elastic adsorbent and the calcula-tion of changes in entropy and internal energy of the adsorbent AR-V at adsorption of n - hexane that is a quantitative fact of variability of micro porous adsorbent in the ad-sorption process. This work will contribute to the development of the theory of equilibrium of adsorption and thermodynamics of adsorption.

Key words: adsorption, adsorbent, adsorbents adsorptive deformation, dilatometric method for measuring of adsorptive deformation of adsorbents, thermodynamics of adsorptive deformation of ad-sorbents
