    Prediction of multicomponent liquid adsorption equilibria (1987)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 33 (1987), S. 551-557

    Notes: A new method of predicting adsorption equilibria for multicomponent liquid solutions on solids has been developed which combines the thermodynamic and kinetic treatments of liquid adsorption. Multicomponent equilibria can be predicted using parameters obtained from binary adsorption data. The method requires the adsorbent capacities, the bulk and surface phase activity coefficients, and the binary adsorption equilibrium constants. The calculation procedure is simpler than other available methods. Predictions are made for the mixture of benzene, ethyl acetate, and cyclohexane on activated carbon at 303 K. The predictions are in quantitative agreement with published experimental data for this system.

    Treatment of gas-solid adsorption data by the error-in-variables method (1986)

    Notes: A recently developed error-in-variables method of calculating regression parameters was applied to the modeling of gas-solid adsorption equilibria. The method accounts for error in all experimental variables in the regression calculations. Regression coefficients from pure component data calculated by the new method were used to predict multicomponent equilibria. The multicomponent predictions using pure component parameters calculated by the error-in-variables method were more accurae than predictions using parameters calculated by conventional least-squares regression.

    Adsorption equilibrium constants and intraparticle diffusivities in molecular sieves by tracer-pulse chromatography (1985)

    Notes: A perturbation chromatography technique using radiotracer gases has been developed to determine the adsorption equilibrium constants and diffusivities in molecular sieves. The ethane and ethylene 13X molecular sieve systems were studied in regions of high concentration. The data obtained by this technique are shown to be in agreement with equilibrium data obtained by static methods and with kinetic data obtained by adsorption uptake and chromatographic methods, but not with kinetic data obtained using NMR techniques. The tracer-pulse chromatographic technique is much more efficient for obtaining gas adsorption equilibria and intraparticle diffusivities and is considerably easier to adapt to wide pressure and temperature ranges than the conventional methods.

    Vacancy solution theory of adsorption using Flory-Huggins activity coefficient equations (1985)

    Notes: New equations for the physical adsorption of gases on solids have been developed based on the vacancy solution model of adsorption in conjunction with the Flory-Huggins activity coefficient equations. The isotherm equation contains three regression parameters: a Henry's law constant, the limiting amount of adsorption, and a gas-solid interaction term. Pure-gas data over a range of temperature can be correlated using only five parameters. Gas-mixture equilibria can be predicted using only the parameters obtained from the pure-gas data. Pure-component, binary, and ternary adsorption equilibrium data on activated carbons, silica, and zeolites over a wide range of conditions have been used to evaluate the model. The results show that, except for a few systems, this model predicts gas-mixture equilibria better than any other model.

    The vacancy solution model of adsorption - improvements and recommendations (1985)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 31 (1985), S. 2075-2081

    ISSN: 0001-1541

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The vacancy solution model of adsorption which uses an activity coefficient equation of the Wilson form has been improved (1) by incorporating temperature dependency into the model, and (2) by development of a functional relationship between the adsorbate-adsorbate binary interaction parameters. This reduces the number of regression parameters and improves the predictive capabilities of the model. Comparisons of this improved model with the Flory-Huggins activity coefficient form of the vacancy solution model are presented for binary and ternary systems. For a priori predictions from pure-component data, the Flory-Huggins form is recommended. If experimental binary data are available for all pairs, the form that most accurately correlates the binary data should be used to predict higher-order systems.
