Abstract

Supported nickel oxide based catalysts were prepared by wetness impregnation method for the in-situ reactions of H2S desulfurization and CO2 methanation from ambient temperature up to 300 °C. Fe/Co/Ni (10:30:60)-Al2O3 and Pr/Co/Ni (5:35:60)-Al 2O3 catalysts were revealed as the most potential catalysts, which yielded 2.9% and 6.1% of CH4 at reaction temperature of 300 °C, respectively. From XPS, Ni2O3 and Fe 3O4 were suggested as the surface active components on the Fe/Co/Ni (10:30:60)-Al2O3 catalyst, while Ni 2O3 and Co3O4 on the Pr/Co/Ni (5:35:60)-Al2O3 catalyst.
