The hydrotalcite route was used to prepare Ni and Co oxides catalysts, with different Ni/Co contents. The catalytic performance of these oxides was investigated with the dry reforming of methane in order to produce energy vector from renewable energy. The samples were characterized, before and after calcination, by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric...
ZSM5 supported nickel (Ni/ZSM5) and cobalt (Co/ZSM5) catalysts with a 7 wt.% total metal loading were prepared by the wet impregnation method. The CO2 reforming of methane reaction was carried out in the 600 to 800°C temperature range at a gas hourly space velocity GHSV = 60000 mL.g−1.hr−1. Above 650°C, methane and carbon dioxide conversions were slightly higher over the Co/ZSM5 solid. During the...
Copper supported on calcined hydrotalcite catalysts were prepared using the memory effect of zinc-aluminium hydrotalcite. Zinc-aluminium was calcined at 400°C and dopped in a copper nitrate aqueous solution for surface hydrotalcite regeneration. The calcination at 500°C of the sample copper/zinc-aluminium (Cu/Zn-Al) (400) leads to an interesting copper mixed oxide supported on calcined hydrotalcite...
