摘要：
LaNiO3/-Al2O3 catalysts containing 10, 15, 20, and 25wt% 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 CO2 reforming of CH4 were tested in a fixed-bed reactor at 700 degrees C, 750 degrees C, and 800 degrees C. LNA-eth with 20wt% Ni exhibited the best activities in dry reforming of methane and a good activity and stability, when it was tested at 800 degrees C during 75h time-on-stream.
