In this study, the feasibility of the p(i)(sat) temperature-dependency approach in predicting mixture adsorption loadings on zeolites is examined. The presented case examples show that IAST, RAST or extended Langmuir together with the pure component saturated vapour pressure p(i)(sat) to describe the temperature dependency of adsorption, can be used to predict mixture adsorption. The approach makes it possible to predict mixture adsorption in various temperature, pressure and composition conditions by utilizing pure component adsorption data at only one temperature. In addition to vapour phase adsorption, the p(i)(sat) temperature-dependency approach is also found to be applicable in modelling liquid mixture adsorption. The approach is a valuable engineering tool especially in cases where there is a lack of adsorption data. The approach can be used e.g., in zeolite membrane permeation modelling, where the adsorption phenomenon has a considerable significance. (C) 2012 Elsevier Ltd. All rights reserved.
