This work presents results of design of ethanol steam reforming (ESR) catalysts based on spinel-type oxides MnxCr3-xO4 promoted by Ru +Ni. Mixed oxides MnxCr3-xO4 (x=0.3-2.7) were prepared via modified Pechini route. Ni and Ru (2 wt.%) were supported by the incipient wetness impregnation. Structural features and microstructure of catalysts were characterized by X-ray diffraction, TEM with EDX, UV-Vis and XPS, reactivity - by H2 and EtOH TPR. The catalytic properties of samples in ESR were studied in diluted and concentrated feeds. According to XRD and UV-Vis data, samples are comprised of several phases. A high activity was observed for catalysts containing MnCr2O4 spinel phase. Catalysts based on 2%Ru+2Ni%/MnCr2O4, both bulk and supported on Al2O3, showed the best results. According to in situ IR spectroscopy data, ESR on spinel-based catalysts proceeds via dehydrogenation route.
