Abstract: The adsorption equilibria of n-heptane, n-octane and n-nonane on silicalite and ZSM-5 have
been measured in the temperature range of 373.15--473.15K under low pressure (0-5.332kPa).
All the experimental data can be represented by a generalized characteristic curve of the
extended adsorption potential theory utilizing the parameter of the initial heat of
adsorption, which is estimated reasonably by a new approach.

Key words: adsorption equilibria, heat of adsorption, n-alkanes, zeolite
