Abstract: For the first time, complex studies were carried out on adsorption deformation – sorbostriction of the microporous carbon adsorbent FAS-3 at adsorption of benzene vapors from the flow of carrier gas – nitrogen in non-equilibrium conditions.  Adsorption isotherms of benzene vapors by the microporous carbon adsorbent FAS-3 under equilibrium conditions has been studied. Calculations of changes in the entropy and internal energy of the adsorbent in the adsorption process were performed.

Keywords: adsorption, adsorbent, adsorption deformation of the adsorbent, the dilatometric method of measuring the adsorption deformation of adsorbents, thermodynamics of adsorption deformation of the adsorbent
