Abstract

An equation is derived for the multimolecular adsorption isotherm in the range where capillary adsorption is insignificant. The equation is demonstrated to apply quantitatively to the entire range of relative vapor pressure. It is shown that this equation reduces to the equation of Brunauer, Emmett, and Teller at lower relative vapor pressures.

Application of this equation to data in the literature showed good agreement. The standard deviation of the data from the equation was in the same order of magnitude as the scatter of the data themselves. Although the application of this equation was largely to water vapor adsorption systems, several applications to other systems correlated equally well.

The basic Brunaeur, Emmett and Teller (BET) approach to multimolecular gas adsorption is extended to apply to both chemical and physical gas adsorption in finite layers on porous materials. Closed form solutions are presented to the resultant mathematical models, and the case of first-layer chemisor
