Resumo: Two series of supported catalyst containing vanadium as the active element were prepared on alumina (AI2O3) and niobia (Nb2O5). Immobilization of the active element was achieved using the grafting technique from VOCl3 in such a way that the amount of vanadium was equivalent to half and one monolayer. The samples were characterized by chemical analysis, X-ray diffraction, BET, PIE, FTIR, TPR, XPS and 51VNMR. Their catalytic properties were evaluated in the oxidative dehydrogenation of propane to propene. These results allowed us to associate acidity and structure of the active sites to the activity and selectivity of prepared samples

Para a imobiliza??o do elemento ativo foi usada a t?cnica de ancoragem a partir do VOCI3 com teores de van?dio equivalentes a meia e uma monocamada. Os s?lidos preparados foram caracterizados por an?lise qu?mica, difra??o de raios-X, BET, PIE, FTIR, TPR, XPS e RMN51V e avaliados para a rea??o de oxida??o desidrogenante de propano a propeno. Os resultados permitiram associar a acidez e a estrutura dos s?tios ativos com a atividade e seletividade dos s?lidos preparados.Submitted by Celso Magalhaes (celsomagalhaes@ufrrj.br) on 2020-11-24T13:13:11Z No. of bitstreams: 1 1995 - Sandra Matias Damasceno.pdf: 882216 bytes, checksum: 6c2879fbd2078d30eeee5096293eaec4 (MD5)Made available in DSpace on 2020-11-24T13:13:11Z (GMT).
