Abstract

The adsorption of methanol-benzene mixtures was studied on adsorbents of different polarity. Besides adsorption measurements, the displacement enthalpy isotherms were determined by flow microcalorimetry. The adsorption exchange process was modelled with calculations utilizing bulk phase activity data, for adsorbents of different polarity. The results provide further possibilities for calculating the surface excess free energy, enthalpy and entropy functions. With respect to adsorption capacity and molar adsorption enthalpy determination, a new equation is proposed.
