| Summary: | Заглавие с экрана Ni-M/Ce0,5Zr0,5O2/Al2O3 catalysts for autothermal reforming of methane (ATR of CH4) were prepared by sequential impregnation method. The effects of the type (M = Pd, Pt, Re, Mo, Sn) and content (M/Ni = 0,03‒0,003) of promoters on the physicochemical characteristics of Ni-M supported catalysts and on their activity to produce hydrogen by ATR of CH4 were studied. It was found that the additive determines NiO dispersion as well as reducibility of Ni2+ species. It was demonstrated that the catalyst performance in ATR of CH4 was correlated with catalyst ability for reduction. The optimal formula of catalyst for effective methane conversion into hydrogen-containing gas was developed. The high and stable yield of hydrogen (70% at 850 °C) was achieved in ATR of CH4 over 10Ni-0,05Pd/10Ce0,5Zr0,5O2/Al2O3 catalyst. |
