Abstract
The energy profile, which is the energy of the adsorbed phase as a function of loading, is essential for characterizing the equilibrium behavior of ad sorbents. The energy of the adsorbed phase is measured directly by calorime try or indirectly by differentiating adsorption isotherms at constant loadi ng. The adsorption isotherm and energy profile are sufficient for the deter mination of thermodynamic variables such entropy and provide a basis for pr edicting the behavior of nonideal, multicomponent mixtures from single-gas isotherms.
