PREDICTION OF ADSORPTION RATE CONSTANTS OF ACTIVATED CARBON FOR VARIOUS VAPORS

In the past decade, a theoretical calculation of the adsorption properties of activated carbon has successfully been used to predict the adsorption capacity for untested vapors after initial characterization of the carbon with a reference vapor. However, using this theoretical approach, it has not been possible to predict the second fundamental property of carbons, namely its adsorption rate constant, and therefore only a family of curves for adsorption performance could be calculated. A new extension of the present theory is proposed which would permit prediction of the adsorption rate constant of vapors, after initial characterization of the carbon with a reference vapor, so that a curve of adsorption performance can be calculated for any vapor needed. © 1979.
