In this Methanation study, efficient nickel (Ni) and nickel-cobalt (Ni-Co), supported on alumina catalysts with different amounts of Ni-Co catalyst Ni and Co were prepared, characterized and used for CO2 methanation under the atmospheric pressure. The Green process catalysts were prepared in the form of extrudates for catalytic tests. The effect of Ni content and the influence of CO2 valorisation Co on Ni catalysts were studied in a packed bed methanation reactor at laboratory scale. An optimal Ni-Co Power-to-gas
