EXPERIMENTAL DETERMINATION OF HEAT EFFECTS THAT ACCOMPANY SORPTION EQUILIBRIUM PROCESSES
Development of the sorption-isosteric method with minimum dead volume for a direct measurement of sorption heats in gas-nanoporous-sorbent systems is reviewed. Advantages and limitations of the technique are assessed and illustrated by concentration dependences of the isosteric sorption heat for various systems, several of which are discussed in the light of molecular simulation. The technique is useful and effective in obtaining highly accurate sorption-thermodynamic data for single gases and gas mixtures by nanoporous materials, e.g., zeolites. These sorption-energetic propeties are accessible as functions of sorption-phase concentration up to saturation values. They also serve for calculation of sorption isostherms for single gases and their mixtures over wide ranges of temperature and pressure-irrespective of phase transitions that may occur in the system.
