A thermodynamic framework is presented to capture the relationship between the pore specific surface areas with the enthalpy of adsorption. An important feature of these adsorbent materials is the maximization of adsorption capacity at Henry’s region. (iv) A considerable progress has been made for the development of novel porous materials with controlled architectures and surface treatment. These equations enable us to compute for the actual specific heat capacity, partial enthalpy and entropy which are essential for the analyses of single-component adsorption processes. (iii) We have developed the complete thermodynamic property fields for a single-component adsorbent + adsorbate system. The purpose of this letter is to fill up the information gap with respect to the state of adsorbed phase to dispel the confusion as to what is the actual state of the adsorbed phase. The derived formulation of the is compared with experimentally measured of adsorbent + adsorbate systems. ![]() (ii) A thermodynamic framework for calculating the specific heat capacity of a single component adsorbent + adsorbate system has been derived and developed using the classical thermodynamics, and these are essential for the design of adsorption processes. ![]() The derived equation for the isosteric heat of adsorption is verified against three sets of judiciously selected adsorbent + adsorbate data that are found in the literature and the predictions are found to agree within the experimental uncertainties of the reported data. ![]() (i) A theoretical framework for the estimation of the isosteric heat of adsorption between an adsorbate (vapor) and an adsorbent (solid) is proposed based on the thermodynamic requirements of chemical equilibrium, Maxwell relations and the entropy of the adsorbed phase.
