Abstract
Thermodynamic theories of adsorption equilibrium in micropores are discussed with special reference to the osmotictheory of adsorption, based on the vacancy solution model, and to the analogy between adsorption and osmotic equilibria.A thermal adsorption equation is derived, and its special cases are discussed, thus giving a quantitative description ofadsorption on microporous adsorbents over a wide range of pressure and temperature. New methods of investigating thekinetics of vapour adsorption on microporous adsorbents and of describing the process theoretically by the bipore modelare reviewed. Good agreement between experiment and theory is obtained. 40 references.
