Abstract: Catalysts based on oxides with a high lattice oxygen mobility and reactivity are known to be able to efficiently transform ethanol into syngas by selective oxidation. Mechanism of this reaction as well as the lattice oxygen mobility over spinel-like Ni+Ru/MnCr2-xFexO4 catalyst were studied by using kinetic methods, SSITKA and pulse microcalorimetry. C-C bond rupture in ethanol molecule seems to be the rate-determining step, while C-H bond breaking in the ethanol dehydrogenation step giving acetaldehyde proceeds easily. The mechanism is described by step-wise red–ox scheme including ethanol oxidative decomposition on metallic sites with participation of oxygen species located at the metal-oxide interface followed by fast reoxidation of partially reduced support sites by O2. A high oxygen mobility in spinel support appears to be the reason of catalyst resistance to coke formation.
