The design of an adsorptive separation process relies on accurate predictions for multicomponent adsorption equilibrium. At present, predictions of adsorption thermodynamics are generally less accurate than those of bulk thermodynamics.
The Cambridge group has recently developed a new adsorption thermodynamic theory, called the Multi-Space Adsorption Model (MSAM). So far, the model has been shown to give good predictions for the adsorption of gaseous mixtures on activated carbons.
The objective of the proposed research project is to modify the MSAM to describe adsorption on zeolites, which are the basis of many industrial adsorptive separation processes. This wlil involve adapting the existing model, which was developed for amorphous solids, to reflect the regular, crystalline structure of zeolites. The modified version will be evaluated by comparing its predictions for multicomponent adsorption with experimental data. The application of the improved model will make it easier and cheaper to achieve optimal designs for adsorptive separation processes.
