Theses catalysts were tested in a fixed-bed reactor system employing steam reforming of ethanol. The operating temperature was 550°C and water/ethanol feed ratio 3/1. Although all catalysts were very active for ethanol conversion and very selective towards the desired products, but that one supported on zirconia microspheres was produced slightly better results. The data reveal high activity of the Cu/Ni/ZrO2 catalyst for ethanol steam reforming and presented a good selectivity for H2.Artigo IPEN-doc 19186 Patentes depositadas em âmbito nacional como indicador de desenvolvimento das tecnologias de produção de hidrogênio2013 - MOREIRA, RENATA; CARVALHO, FATIMA M.S. de; BERGAMASCHI, VANDERLEI S.; POLITANO, RODOLFO
