13. "Desenvolvimento de catalisadores de rutênio suportado em CeO2/Al2O3 para a reação de reforma a vapor e oxidativa de etanol" / "CeO2/Al2O3-supported ruthenium catalysts for the steam and oxidative reforming of ethanol"
Aiming at hydrogen production, as a source of renewable energy, Ru/CeO2-Al2O3 catalysts were studied in ethanol steam reform and ethanol oxidative reforming. The effect of the support and metal/support interaction was verified on the activity and selectivity of the reactions. The supports and catalysts were characterized by x-rays dispersive spectroscopy (XD

14. "ZrO2/g-Al2O3-supported platinum catalysts for the steam reforming of ethanol" / "Catalisadores de platina suportados em ZrO2/g-Al2O3 para a reação de reforma a vapor de etanol"
In this work catalysts of platinum supported on g-alumina (g-Al2O3), oxide of zirconium (ZrO2) and mixed oxide of zirconium and g-alumina had been prepared and characterized. The bi-component supports containing ( 15%) ZrO2/g-Al2O3 had been prepared by two different methods : in the first, an acid suspension of comercial oxide of zirconium was used and in th

15. "Caracterização e aplicação de catalisadores de cobalto suportados em g-Al2O3 e SiO2 para produção de hidrogênio a partir da reforma a vapor e oxidativa de etanol" / "Characterization and application of cobalt catalyst supported on g-Al2O3 e SiO2 for the production of hidrogen from the ethanol steam and oxidative reforming"
Neste trabalho foram preparados catalisadores Co/Al2O3 e Co/SiO2 por impregnação com concentração metálica entre 4,0% e 20,0% e avaliados frente às reações de reforma a vapor e reforma oxidativa de etanol, com o objetivo de avaliar a estabilidade catalítica e o rendimento em hidrogênio. Os catalisadores foram caracterizados por espectrofotometria d

16. Reforma a vapor do etanol sobre catalisadores de Ni e Co suportados.
The Ni and Co catalysts supported on Al2O3 and 12%La-Al2O3 and the carrier 12%La-Al2O3 were prepared by impregnation of the support with an aqueous solution of corresponding nitrates metals. The catalysts were characterized by temperature programmed reduction (TPR), specific surface area (B.E.T.) and XRay Diffraction (XRD). The reaction rate for decompositio
