In the present work, 5wt% Ni-Ce0.85Sm0.15O2-δ powders were synthesized by citrate-nitrate auto-combustion method and structured catalysts based on NiCrAl alloy foam were prepared by wash-coating technique. The open-pores of the foam enhance the heat and mass transfer. Besides, the oxygen vacancies of SDC promote the CH4 and CO2 activation for carbon suppression. Microstructural analysis of Ni-SDC/NiCrAl faom structured catalyst displayed a homogeneous distribution of the catalytic layer. Catalytic tests for DRM at 800 °C showed that the CH4 conversion was 87%, close to thermodynamic equilibrium, and the yield of H2 was 76%, indicating that the structured catalyst is suitable for indirect internal reforming in SOFCs.

Abstract
In the present work, 5wt% Ni-Ce0.85Sm0.15O2-δ powders were synthesized by citrate-nitrate auto-combustion method and structured catalysts based on NiCrAl alloy foam were prepared by wash-coating technique. The open-pores of the foam enhance the heat and mass transfer. Besides, the oxygen vacancies of SDC promote the CH4 and CO2 activation for carbon suppression. Microstructural analysis of Ni-SDC/NiCrAl faom structured catalyst displayed a homogeneous distribution of the catalytic layer. Catalytic tests for DRM at 800 °C showed that the CH4 conversion was 87%, close to thermodynamic equilibrium, and the yield of H2 was 76%, indicating that the structured catalyst is suitable for indirect internal reforming in SOFCs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
