Abstract

Catalytic performance and characterization of Pd/Ni_0.2Mg_0.8Al₂O₄ were investigated in oxidative steam reforming of methane under atmospheric and pressurized conditions. Pd/Ni_0.2Mg_0.8Al₂O₄ showed much higher methane conversion under high partial pressure of steam, where Ni_0.2Mg_0.8Al₂O₄ lost the reforming activity because the Ni species was oxidized under atmospheric pressure. In addition, the addition of Pd on Ni_0.2Mg_0.8Al₂O₄ was effective to improve the stability and resistance to coke formation in oxidative steam reforming of methane under pressurized conditions. On the other hand, the formation of Pd-Ni alloy over Pd/Ni_0.2Mg_0.8Al₂O₄ was confirmed from the characterization results of TPR, TEM, EXAFS and FTIR, and this can contribute to high catalytic performance of Pd/Ni_0.2Mg_0.8Al₂O₄.
