(719j) Muti-Component Gas Adsorption on MSC5A by Chromatographic Method

The combination of chromatographic method and moment analysis of the response peaks is one of the useful techniques to study adsorption equilibrium and adsorption rate. Perturbation chromatography with the mixed multicomponent adsorbate gas carrier (two adsorbates) has been applied to several studies on adsorption. In this work, perturbation chromatography with multicomponent gas carrier (two adsorbates with inert gas) and non-equilibrium thermodynamics liner law were applied for discussion of the interference effect and the displacement effect (those are cross effects) on mass transfer in multicomponent gas adsorption. Moment analysis method and stop & go simulation method were utilized to obtain each mass transfer parameters of adsorbate gases. In this work, dependency of micropore diffusion on amount adsorbed and correlation of micropore diffusion with chemical potential driving force for microporous adsorbent were confirmed. Cross effect in micropore diffusion was found.
