Реферат: The selective CO methanation in hydrogen-rich gas mixtures in the presence of CO2 is a promising way for deep CO removal designed for low-temperature proton-exchanged membrane fuel cell feeding applications, as well as a challenging fundamental problem of substrate-selective hydrogenation. Catalytic properties of Ni-, Co- and Fe/CeO2 catalysts, prepared from nitrate and chloride precursors, in the selective CO methanation were studied. The Ni(Cl)/CeO2 catalyst, prepared from NiCl2 precursor, was the most efficient, being less active than Ni/CeO2 and Co/CeO2, but considerably more selective. This phenomenon could be explained by ceria surface blocking by chlorine species and appropriate inhibition of CO2 hydrogenation activity
