This work was focused on the study of the catalytic behaviour of nickel aluminate supported either on ceria or ceria-zirconia (NiAl2O4/CexZr1-xO2, x= 0.13 and 1, 14 wt.% Ni) for the steam reforming and partial oxidation of methane. Activity results revealed that these catalytic formulations showed a notable performance for POM under stoichiometric conditions (molar ratio O/C = 1), irrespective of the composition of the support. However, under more severe reforming conditions (O/C = 0.8) NiAl2O4/CeO2 was the optimal catalyst as its marked reducibility helped in minimising the negative effect of coking. Conversely, the NiAl2O4/Ce0.13Zr0.87O2 sample was the most efficient system for SRM due to its high hydrothermal stability.
