Abstract

Abstract: The effect of CeO₂ and CaO promoters on the ignition performance over Ni/MgO-Al₂O₃ catalyst for the partial oxidation of methane (POM) to synthesis gas was investigated. It was found that the POM reaction could not be ignited over lwt%Ni/MgO-Al₂O₃ catalyst without the promoters in the temperature range from 773 K to 1073 K. CeO2 and CaO promoters enhanced the ignition performance and the POM reactivity of lwt%Ni/MgO-Al2Oa catalyst remarkably. Moreover, the improving effect became greater with the increase of the promoter content under the investigated reaction conditions. The modification effects of CeO₂ and CaO promoters were closely related to the concentration and reducibility of the surface and bulk oxygen species.
