摘要: Abstract Perovskite oxide LaCuO 3 and LaCu 0.53 Ni 0.47 O were prepared using the sol–gel citrate method, whereas 5% NiO/LaCuO was by impregnation. The products obtained, after heat treatment under air at 800 °C, characterized several techniques such as: thermogravimetric analysis (TG), inductively coupled plasma atomic emission spectroscopy (ICP–AES), X-ray diffraction (XRD), Brunauer–Emmett–Teller method (BET) temperature programmed reduction (TPR). After reduction, catalysts evaluated in reforming of methane reaction continuous flow with CH 4 /CO 2 ratio equal to 1, atmospheric pressure a range [500–700 °C]. catalytic activity tested fixed bed reactor. At 700 °C, amount consumed its lowest presence conversion increased 60% case precursor. best results obtained precursor, whereby augmented 16.5% compared that .
