Effect of palladium addition on catalytic activity in steam methane reforming over Ni-YSZ porous membrane
This study investigated the additive effects of palladium, and the deposition method of palladium on Ni-YSZ porous membrane in steam methane reforming. Pd-Ni-YSZ porous membrane prepared by the wet impregnation method showed superior catalytic activity, where the methane conversion reached 94.6% at 650 degrees C, with H-2 yield above 3.9. The palladium particles were well dispersed, and the Pd-Ni-YSZ porous membrane exhibited high adsorption capacity for water. The addition of palladium and the deposition method of palladium are very important for the steam methane reforming reaction. Copyright (c) 2014, Hydrogen Energy Publications, LLC.
