Production of hydrogen by methane dry reforming over ruthenium-nickel based catalysts deposited on Al2O3, MgAl2O4 and YSZ

In this work, monometallic with low metal content (1 wt.% of Ru or 5 wt.% of Ni) and bimetallic catalysts (1 wt.% Ru-5 wt.% Ni) deposited on alumina (Al2O3), magnesium aluminate spinel (MgAl2O4) and yttria-stabilized zirconia (YSZ) were prepared by wet impregnation and tested in DRM. The results showed that the monometallic 5 wt.% Ni/MgAl2O4 catalyst exhibited excellent catalytic activity for DRM. Furthermore, it was found to be very stable without any deactivation after 50 h under-reacting mixture.
