Catalytic decomposition of SO3 over Pt/BaSO4 materials in sulfur-iodine cycle for hydrogen production / Bhari Mallanna Nagaraja in Industrial & engineering chemistry research, Vol. 48 N°3 (Février 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°3 (Février 2009) . - p. 1451–1457 Titre : Catalytic decomposition of SO3 over Pt/BaSO4 materials in sulfur-iodine cycle for hydrogen production Type de document : texte imprimé Auteurs : Bhari Mallanna Nagaraja, Auteur ; Kwang Deog Jung, Auteur ; Byoung Sung Ahn, Auteur Année de publication : 2009 Article en page(s) : p. 1451–1457 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Hydrogen  --  Production  sulfur  Iodine  Pt/BaSO4  SO3 Résumé : Various platinum-supported barium sulfate catalysts have been employed for SO3 decomposition in sulfur−iodine cycle to produce hydrogen. Before impregnation of platinum, barium sulfate as a support has been prepared by different methods, i.e., using ethylene glycol (EG) and water by dispersion method and EG and propanol by spray pyrolysis. The influence of the supports on catalytic performance was examined with three catalysts: 1.0Pt/BaSO4 (PrOH), 1.0Pt/BaSO4 (EG), and 1.0Pt/BaSO4 (H2O) at various temperatures for SO3 decomposition. 1.0Pt/BaSO4 (PrOH) prepared by spray pyrolysis showed high SO3 conversion (62%) at low temperature (1023 K) compared with the other catalysts prepared by dispersion method. The effect of Pt loading on catalytic activity has been performed with BaSO4 impregnated by various amounts of platinum. Under identical conditions, the 1.0Pt/BaSO4 catalyst showed the highest catalytic performance because of high surface area and small particle size of platinum.
