Vacancy solution theory of adsorption from gas mixtures

Journal Article · · AIChE J.; (United States)
The new correlation based on vacancy-solution theory, reports Pennsylvania State University, improves predictions of gas-mixture adsorption equilibria from single-component adsorption isotherm data. The new method is more general, simpler to apply, and more accurate than other available models. For an adsorption system, the binary parameters - adsorbate and vacancy - are obtained from regression of the pure-gas adsorption data with the vacancy-solution isotherm equation. These parameters are then used to predict multicomponent adsorption equilibrium, assuming that the adsorbate-adsorbate interactions are negligible. Penn State has verified the new correlation on two different kinds of binary adsorption systems: mixtures of O/sub 2/, N/sub 2/, and CO on zeolite 10X and mixtures of light hydrocarbons on Nuxit-AL activated carbon.
