Nonideality of binary mixtures in the adsorbent micropores

Analysis of a binary equilibrium in a distinct micropore showed that the no nuniformity of the adsorption field results in a negative deviation of the adsorption solution from ideal behavior. This deviation is due to a decreas e in the entropy and internal energy caused by rearrangement of adsorbed mo lecules. Different interactions between identical and different molecules i n distinct micropores also result in a negative deviation from ideal behavi or. A criterion was formulated that allows one to elucidate how the deviati on from ideality depends on the nonuniformity of the adsorption space and t he character of the interaction between molecules in a micropore.
