Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N° 11 (Juin 2009) . - pp. 5223–5229 Titre : Selectivity and stability enhancement of iron oxide catalyst by ceria incorporation for selective oxidation of H2S to sulfur Type de document : texte imprimé Auteurs : D. D. Eslek Koyuncu, Auteur ; Sena Yasyerli, Auteur Année de publication : 2009 Article en page(s) : pp. 5223–5229 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Iron oxide catalysts H2S Selective oxidation Ceria incorporation Résumé : Cerium incorporated iron oxide catalysts and a pure iron oxide catalytic material were prepared by the complexation technique and their catalytic performances were investigated for selective oxidation of H2S to elemental sulfur in a fixed-bed flow reactor. Ce−Fe mixed oxide catalyst having a Fe/Ce ratio of 1/1 (2Fe−2Ce) showed complete conversion and very high sulfur selectivity in the temperature range of 200−300 °C. Sulfur selectivity and stability of iron oxide catalyst was significantly enhanced by the incorporation of cerium into the catalyst structure. It was concluded that incorporation of ceria into the catalyst structure significantly improved the redox ability of the catalyst.
