Study on Ni Catalytic Hydrogenation of Carbon Dioxide for Methane

Abstract:

Article Preview

Catalyst by different carriers prepared of carbon dioxide conversion sequence is: Ni/TiO2 > Ni/γ-Al2O3 > Ni/MgO > Ni/SiO2. Second metal, Co, Mn, Cu, La and Ce, was significantly enhanced the activity of methanation nickel-based catalysts in the carbon dioxide methanation reaction, but second metal of Cu was bad for the activity of methanation. The 10%Ni/Al2O3 and 2.5%Ce-10%Ni/Al2O3 catalysts were characterized by TG and H2-TPR,it was revealed to Ce which is benefit for reduce NiO reduction temperature and the optimal reduction temperature of the catalysts in between 400°C and 500 °C
