The knowledge of the heat of adsorption is essential for a realistic modeling in many adsorption processes. The adsorption heat is also a direct indicator of the heterogeneity of the interaction between the adsorbate (either a pure gas or a mixture) and the adsorbent. However, the amount of experimental and theoretical work dedicated to the determination of adsorption isotherms far exceeds that dedicated to heats of adsorption. This can be explained by the fact that the measurement of the heat of adsorption is significantly more difficult and expensive than the measurement of adsorption isotherms.
