Abstract: A review. This paper presents results of research of syngas generation by oxidative or steam reforming of hydrocarbons and oxygenates in structured catalytic reactors. Development of structured catalysts included design of active components stable to coking and sintering while efficiently transforming different types of fuels into syngas. It was based upon constructing nanocomposites comprised of components efficient in fuel mols. activation (Ni, Cu, precious metals, etc) and ceria-containing mixed oxides which provide a high rate of oxidants (O2, H2O, CO2) activation and supply of oxygen-containing species to the perimeter of metal particles to consume activated C-H-O fragments. The catalyst development was linked to reactor design. To ensure efficient heat and mass -transfer management required for high performance of structured catalytic reactors, several types of heat-conducting monolithic substrates comprised of refractory alloys and cermets (including microchannel structures) were developed. Procedures for supporting protective layers and active components on these substrates were successfully elaborated. Several types of pilot-scale reactors (with the radial or the axial flow direction) equipped with unique liquid fuel evaporation and mixing units and internal heat exchangers were designed and manufactured Extended tests of these reactors fed by fuels from C1 to gasoline, mineral and sunflower oil have been carried out with a broad variation of exptl. parameters including stability tests up to 1000 h. Performance anal. has been made with a due regard for equilibrium restrictions on the operational parameters. Transient behavior of the monolith reactor during start-up (ignition) of the methane partial oxidation to synthesis gas was studied and analyzed via math. modeling based upon detailed elementary step mechanism. This provides required bases for theor. optimization of the catalyst bed configuration and process parameters.
