Abstract: In two recent studies from this laboratory, a dual resistance model with chemical potential gradient as the driving force for transport and empirical correlations to account for the strong concentration dependence of the thermodynamically corrected transport parameters was proposed and verified for the uptake of oxygen, nitrogen, and their mixtures in the micropores of Bergbau Forschung and Takeda carbon molecular sieve (CMS) samples. In this paper, the same model has been further verified with integral uptakes of carbon dioxide, methane, their binary mixtures, as well as their ternary mixtures with nitrogen in the two CMS samples. Inadequacy of the Langmuir model and IAS-Langmuir combination for these gases has been discussed in detail. It has been demonstrated that, for these gases, the multisite Langmuir model is much more effective in fitting the unary equilibrium data and predicting the mixture isotherms in CMS.
