A New preparation method for LaNiO3 perovskite for dry reforming of methane

LaNiO3 perovskite-type was prepared successfully by impregnation method with ethanol and acetic acid as solvent. After reduction, catalytic activity in CO2 reforming of CH4 was tested in a fixed bed reactor at 700, 750 and 800˚C. It was found that LaNiO3 prepared by this new method, shows good activity, selectivity and long term stability for dry reforming of methane at 800˚C. In all tests at different temperatures CO2 conversion is lower than CH4 conversion. This catalyst produces higher H2/CO ratio at low flow rate in comparison with the other preparation methods which published in the literature for this catalyst.
