Catalytic Properties and Resource Characteristics of Modified Nickel Composites in the Processes of Oxidative Reforming of C1-C4 Alkanes

Modified nickel composites based on stabilized zirconia as prototypes of anode materials of solid oxide fuel cells (SOFC) showed high catalytic activity and stability in the oxidative reforming of alkanes (tri-reforming of methane and steam-(oxygen) reforming of butane). Modification of Ni-10Sc1CeSZ composite with Cu and CeO2 increases its resistance to carbonization, and doping with platinum or palladium (0.1 wt.%) increases the resistance to H2S poisoning. Structured Ni-(CeO2, La2O3)-Al2O3/cordierite catalysts are characterized by high activity and stability in the oxidative reforming of C-1-C-3 alkanes into syngas and can be effective in an external processor integrated with SOFC. Bench tests of the fuel cell showed the achievement of acceptable electrical characteristics.

Automated summary

Research has shown that modified nickel composites based on stabilized zirconia exhibit high catalytic activity and stability as anode materials for solid oxide fuel cells (SOFC) in the oxidative reforming of alkanes, such as tri-reforming of methane and steam- (oxygen) reforming of butane. Modification of Ni-10Sc1CeSZ composite with Cu and CeO2 enhances its resistance to carbonization, while doping with platinum or palladium (0.1 wt.%) improves its resistance to H2S poisoning. Structured Ni-(CeO2, La2O3)-Al2O3/cordierite catalysts demonstrate high activity and stability in the oxidative reforming of C-1-C-3 alkanes into syngas and can be effectively integrated with an external processor in SOFC systems. Bench tests of the fuel cell show acceptable electrical characteristics.
