Correlation of adsorption isotherms of hydrogen isotopes on mordenite adsorbents using reactive vacancy solution theory
Abstract
The authors have applied the isotherm equations derived from the reactive vacancy solution theory (RVST) to correlation of experimental and highly nonideal adsorption isotherms of hydrogen and deuterium on a mordenite adsorbent, and have examined the ability of the isotherm equations to match this correlation. Several isotherm equations such as Langmuir, Freundlich, Toth, Vacancy Solution Theory and so forth were also tested, but they did not work. For the LangmuirFreundlich equation tests have indicated that its 'ability to correlate' of the adsorption isotherms is not satisfactory. For the multisite LangmuirFreundlich (MSLF) equation the correlation of the isotherms appears to be somewhat improved but remains unsatisfactory. The results show that the isotherm equations derived from RVST can better correlate the experimental isotherms.

Correlation and prediction of liquidphase adsorption on zeolites using group contributions based on adsorbatesolid solution theory
Both correlation as well as prediction of experimental data for the adsorption of various binary liquid mixtures of alkanes and alkenes on NaX at different temperatures are presented. The theoretical background is based on the adsorbatesolid solution theory which conceives the adsorbed phase to be a mixture of the adsorbed species (adsorbate) and the adsorbent as an additional component. With the introduction of the Gibbs excess energy G{sup E*} for this hypothetical mixture, activity coefficients and composition of the adsorbed phase may be calculated. The Biggs excess energy and thus the activity coefficient of the adsorbed species depend strongly onmore » 
The effects of flow through highly porous adsorbents on adsorption rates with favorable (nonlinear) isotherms
To increase diffusion rates into adsorbents, efforts are being made to increase the porosity of adsorbents by increasing both the number of porous passages into the particles and the size of those passages. These efforts can eventually result in some flow of fluid through the particles from the pressure drop through the adsorption bed. Earlier papers have pointed out that such flows can contribute to the effective mass transfer rates. This paper extends the earlier studies by considering the effects of nonlinear (favorable) isotherms. 
Universal singularities of multilayer adsorption isotherms and determination of surface area of adsorbents
The singularity in the adsorption isotherm for macroporous and nonporous adsorbents is considered as a universal function that can be characterized with two parameters: a coefficient of proportionality, K, and an exponent, d. It is shown that the value of K is proportional to the adsorbent surface area but does not depend on the nature of the adsorbent. This leads to a new method to determine the surface area of an adsorbent, S, that is independent of the form of the adsorption isotherm at low and moderate reduced pressures. Comparison with the BET areas for nitrogen shows that the newmore »
