Description:
LaNiO 3 /γ-Al 2 O 3 catalysts containing 10, 15, 20, and 25 wt % Ni were prepared by a combination of sol gel with propionic acid as solvent and an impregnation method (LNA-acid) as well as with ethanol as solvent and addition of acetic acid (LNA-eth). Catalytic activities towards CO 2 reforming of CH 4 were tested in a fixed-bed reactor at 700 °C, 750 °C, and 800 °C. LNA-eth with 20 wt % Ni exhibited the best activities in dry reforming of methane and a good activity and stability, when it was tested at 800 °C during 75 h time-on-stream. LaNiO 3 /γ-Al 2 O 3 catalysts containing varying amounts of Ni were prepared by a combination of sol gel with propionic acid as solvent and an impregnation method as well as with ethanol as solvent and addition of acetic acid. Catalytic activities towards CO 2 reforming of methane were tested in a fixed-bed reactor at high temperatures.
