Influence of energetic heterogeneity and lateral interactions between adsorbed molecules on the kinetics of gas adsorption / Krzystof Nieszporek in Industrial & engineering chemistry research, Vol. 50 N° 6 (Mars 2011)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 6 (Mars 2011) . - pp. 3078-3088 Titre : Influence of energetic heterogeneity and lateral interactions between adsorbed molecules on the kinetics of gas adsorption Type de document : texte imprimé Auteurs : Krzystof Nieszporek, Auteur ; Tomasz Banach, Auteur Année de publication : 2011 Article en page(s) : pp. 3078-3088 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Adsorption Kinetics Heterogeneity Résumé : The kinetics of pure gas adsorption on energetically heterogeneous solid surfaces has been studied by statistical rate theory. The theoretical investigations take into account the influence of lateral interactions between adsorbed molecules. The energetic heterogeneity of the adsorption system has been described by the rectangular energy distribution function. The obtained kinetic expression is based on the exact solution of the integral equation approach. The experimental systems of alkane adsorption on activated carbons were used for quantitative analysis. As a result, a good simultaneous description of equilibria and kinetics in these systems was obtained.
