Zeolites treated with silicon tetrachloride vapour. Part 3.—Atom–atom potential calculations for the adsorption of xenon

Abstract
Adsorption isotherms for xenon on a series of samples of zeolite Y dealuminated with silicon tetrachloride vapour have been measured and used to calculate differential heats of adsorption, differential entropies and activity coefficients. Atom–atom potential calculations indicate preferred adsorption sites for xenon. For loadings higher than one atom of xenon per zeolitic supercage the formation of xenon clusters is predicted by calculations and has been verified experimentally.
