Influence of isomorphous substitution in MFI-type materials on the diffusion of n-hexane: Molecular dynamic studies

摘要

Theoretical studies of the behaviour of an adsorption system MFT-hexane were performed with a molecular dynamic method. Investigation of influence of isomorphous substitution on diffusion coefficients was the main objective. It was found that the presence of metals other than silicon in the zeolite framework might cause an increase in the diffusion coefficients. However, it is small, independently of the adsorption level.
