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 IngenieríaMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-sa/4.0/https://creativecommons.org/licenses/by-nc-sa/2.5/co/Atribución-NoComercial-CompartirIgual 2.5 Colombia (CC BY-NC-SA 2.5 CO)info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2CatalizadoresVanadioCharacterization 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 ácidoArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionRev.
