Abstract

The effects of CeO₂ and CaO composite promoters on the properties of eggshell Ni/MgO-Al₂O₃ catalysts of 1.5 mm diameter for the partial oxidation of methane to syngas were investigated. The addition of 1wt.% promoters could enhance the catalytic performance of the Ni/MgO-Al₂O₃ catalyst, while further increasing the promoter content to 4wt.% results in the decrease of reactivity. The catalytic property is related to the oxidizability of surface nickel species.
