Water-gas-shift kinetic over nano-structured iron catalyst in Fischer–Tropsch synthesis / Ali Nakhaei Pour in Journal of natural gas science and engineering, Vol. 2 N° 2-3 (Juillet 2010) 

Public ISBD [article]  in Journal of natural gas science and engineering > Vol. 2 N° 2-3 (Juillet 2010) . - pp. 79–85 Titre : Water-gas-shift kinetic over nano-structured iron catalyst in Fischer–Tropsch synthesis Type de document : texte imprimé Auteurs : Ali Nakhaei Pour, Auteur ; Mohammad Reza Housaindokht, Auteur ; Jamshid Zarkesh, Auteur Année de publication : 2012 Article en page(s) : pp. 79–85 Note générale : Génie Chimique Langues : Anglais (eng) Mots-clés : Fischer–Tropsch  synthesis  Water-gas-shift  reaction  Iron  catalyst  Kinetics Résumé : Kinetic modeling of the water-gas-shift (WGS) reaction over a nano-structured iron catalyst under Fischer–Tropsch synthesis (FTS) reaction conditions is investigated. The Fe/Cu/La/Si nano-structured catalyst was prepared by co-precipitation in a water-in-oil microemulsion. A number of Langmuir–Hinshelwood–Hougen–Watson type rate equations based on possible reactions sets originated from the formate and direct oxidation mechanisms, are derived. By considering experimental data measured over a wide range of reaction conditions, discrimination between the various rate equations is investigated during this study. WGS rate expressions based on the formate mechanism were found to provide an improved description of the WGS kinetic data.
