Abstract
To solve the problem of adsorption equilibrium predication of multicomponent mixed-gases from the knowledge of adsorption isotherms for only single-component gases, a new model (Langmuir-Freundlich-Langmuir) considered the influence of adsorbent surface heterogeneity was developed for correlating the unary equilibria, which assumed that the adsorption behavior happened on two adsorption sites which were different from each other due to their different adsorption energy. In the predication of adsorption equilibria for the two-component mixed-gases, there were two boundary conditions caused by the different arrangement of two types of sites and only one case would turn out to be the correct correlation, and the prediction of adsorption equilibria for the three-component mixed-gas achieved good results. Several factors affecting the accuracy of prediction for the two-component mixed-gases were discussed from the selection of single-component model and the construction of multicomponent equilibrium prediction equation.关键词
