| Abstract: | Ni/sepiolite and Ni-Sm/sepiolite methanation catalysts are prepared by impregnation. The activities of both catalysts for carbon monoxide methanation are investigated. The effect of samarium on Ni/sepiolite is studied by using heat resistance, XPS and poisoning of CS2. The result shows that the addition of samarium can increase CO methanation activity, heat stability and anti-poisoning ability of Ni/sepiolite, and it decrease the binding energy of Ni2p3/2. |
