PREDICTING ADSORPTION IN ONE-DIMENSIONAL ZEOLITE PORES WITH THE EXACTTHEORY OF ONE-DIMENSIONAL HARD-RODS

The exact statistical mechanical theory of a one-dimensional hard-rod fluid in an arbitrary external field is applied to the adsorption of s imple molecules into nearly one-dimensional zeolitic pores, using a ze olite-sorbent interaction potential based on the system of xenon in mo rdenite. The effect is explored of changing the zeolite-sorbent intera ction on adsorption. By optimizing one parameter in the model, the res ults of this theory compare well with experimental isotherms of xenon in mordenite.
