Реферат: Main factors controlling performance of metal-supported doped ceria-zirconia catalysts of natural gas and biofuels transformation into syngas and hydrogen at short contact times are elucidated by using combination of structural, spectroscopic and unsteady-state kinetic methods. Realization of bifunctional mechanism with fuel molecules activation on metal sites, oxidants activation on oxide sites followed by the diffusion of oxygen-containing species to metal/support interface where they transform CHxOy species into syngas was reliably demonstrated, and kinetic parameters of basic stages were estimated. Strong metal-support interaction, specific defect structure and developed interfaces are crucial for high activity and coking stability of these catalysts. Monolithic catalysts comprised of optimized nanocomposites on heat-conducting substrates provide high and stable performance in transformation of a variety of fuel into syngas at short contact times.
