Modification of activity and selectivity of NiMo/SBA-15 HDS catalysts by grafting of different metal oxides on the support surface / Tatiana Klimova in Industrial & engineering chemistry research, Vol. 48 N°3 (Février 2009)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 48 N°3 (Février 2009) . - p. 1126–1133 Titre : Modification of activity and selectivity of NiMo/SBA-15 HDS catalysts by grafting of different metal oxides on the support surface Type de document : texte imprimé Auteurs : Tatiana Klimova, Auteur ; Laura Peña, Auteur ; Lilia Lizama, Auteur ; Cecilia Salcedo, Auteur Année de publication : 2009 Article en page(s) : p. 1126–1133 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Catalysts Metal Oxides Résumé : In the context of searching for new catalysts for hydrodesulfurization (HDS) of petroleum, in the present work a series of NiMo catalysts supported on SBA-15 materials modified by different metal oxides were prepared and tested in dibenzothiophene HDS. The behavior of the HDS catalysts prepared using SBA-15 supports grafted with alkaline earth metal oxides (MgO, CaO, BaO) is described for the first time and compared to that observed for the supports modified with alumina (Al2O3) or transition metal oxides (TiO2, ZrO2) in order to inquire into the effect of the nature of the metal oxide incorporated in the support on the catalytic activity and selectivity of the NiMo catalysts.
