Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 22 (Juin 2012) . - pp. 7584-7589 Titre : Kinetic study of diesel soot combustion with perovskite catalysts Type de document : texte imprimé Auteurs : Simelys Hernandez, Auteur Année de publication : 2012 Article en page(s) : pp. 7584-7589 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Catalyst  Combustion  Soot  Kinetics Résumé : The objective of this paper is to analyze the kinetics of soot combustion, promoted by several catalysts, through differential scanning calorimetry (DSC) and thermogravimetic analysis (TGA). All the catalysts are substoichiometric or alkalimetal substituted perovskites (La0.9CrO3, La0.8CrO3, La0.9Rb0.1CrO3, La0.9Na0.1CrC3, La0.9Ku0.1CrO3,La0.8Cr0.9Li0.1O3) on the basis of the LaCrO3 standard, which was found to be active for this reaction in previous studies conducted by our group. Different model-free iso-conversion methods with the DSC data were used to determine the activation energies. Instead, thermogravimetric data were employed to determine the oxygen reaction order.
