Objects of research - Ni-catalyst compositions REEO-Al2O3 (REE = La, Ce) to produce hydrogen and synthesis gas and multicomponent Ni-based composites containing Sc and Ce-stabilized zirconia (10Sc1CeSZ), as prototypes SOFC anode materials. Purpose - to optimize the composition of structured nickel-aluminum and nickel-zirconium composite catalysts for their resource characteristics in the processes of oxidative reforming of natural gas components Research Methods - a set of methods for studying catalysts and catalytic reactions - kinetic method, X-ray phase analysis, temperature-programmed reduction with hydrogen, a temperature-programmed oxidation of water and oxygen, transmission electron microscopy. Optimized composition of high-performance catalysts Ni-MxOy / Al2O3, (MxOy: Na2O, K2O La2O3, CeO2, NiO) on structured ceramic media (cordierite) for the processes of reforming methane and C2-C4-alkanes (oxygen, steam, carbon dioxide conversion) to obtain hydrogen (synthesis gas, in particular with a given ratio of H2 / CO). Character impact modifiers / alkali dopant oxides, rare earth elements on the selectivity, yield of target products (hydrogen, syngas), resistance to sulfur-containing compounds and loss of activity due to the accumulation of carbon. Composites designed Ni-Cu-CeO2-10Sc1CeSZ and Ni-PGM-10Sc1CeSZ (IGG - Pt, Pd), which have a high catalytic activity (100% conversion of butane and methane at 650 - 700 ° C), resistance to carbonization and operation stability butane steam reforming processes (8 hours) and tri-methane reforming (32 hours in repeated cycles of operation) at temperatures of 600 - 800 ° C. The catalyst regeneration mode is proposed, which provides a high stability of the active Ni-Pd-10Sc1CeSZ composite after 3h. operation during tri-reforming methane in the presence of H2S. Keywords: zirconia, nickel steam reforming, tri-reforming, ethane, methane, propane, butane, anode, solid oxide fuel cell. Product Description popup.authors Губарені Є.В. Канцерова М.Р. Курилець Я.П.
