Abstract

The reforming of methane with carbon dioxide was studied over nickel supported on αAl₂O₃, γAl₂O₃, αAl₂O₃+ SiO₂, SiO₂, ZrO₂, MgO and modified either by transition metallic adducts (Co, Cu and Fe ) or by alkaline promoters Na, K. A strong influence of support nature on the catalytic activity was observed. The catalytic activity of Ni/αAl₂O₃ was very similar to that of Ni/γAl₂O; however, more coking was observed over the latter. Thus, the methane reforming activity decreases in the following order: αAl₂O₃ > γAl₂O₃ > SiO₂ > αAl₂O₃ + SiO₂ > ZrO₂, MgO. The nickel catalysts properties were also affected by metallic additives (Co, Cu and Fe ) and by alkaline promoters Na, K.
