RESUMEN: Muestras de V2O5/SiO2-γAl2O3 desactivado durante la producción de ácido sulfúrico se trataron con ácido con el fin de recuperar el vanadio. Los materiales se caracterizaron mediante técnicas de temperatura programada: TPR-H2, TPO-O2, TPD-NH3, y TGA-DTA con el fin de determinar el efecto de las especies responsables de la desactivación en la recuperación del metal. Análisis por DRX y UV-Vis se utilizaron para confirmar algunas señales obtenidas en los perfiles de temperatura programada. Los resultados sugieren que la presencia de sulfovanadatos y óxidos de vanadio en las muestras tratadas hacen difícil recuperar más del 86% del vanadio presente en las muestras de catalizador. |

Fresh, spent, and acid treated samples were characterized by temperature-programmed techniques: TPR-H2, TPO-O2, TPD-NH3 and, TGA-DTA in order to determine the effect of deactivating species on vanadium recovery. DRX and UV-Vis techniques were used to confirm several signals from the temperature-programmed profiles. The results suggest that vanadium sulfovanadates and oxides in treated samples strongly interact with the support making it difficult to get more than 86% vanadium recovery.6application/pdfengUniversidad de Antioquia, Facultad de IngenieríaCatálisis AmbientalMedellín, Colombiainfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARTArtículo de investigaciónhttp://purl.org/coar/version/c_970fb48d4fbd8a86Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-sa/2.5/co/http://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-sa/4.0/CatalizadoresVanadioCharacterization by temperature programmed techniques of spent and acid treated vanadium catalystsCaracterización por técnicas de la temperatura programada de catalizadores de vanadio desactivados y tratados con ácidoRev.
