摘要: 制法不同的MgO对甲烷氧化偶联的催化性能相差悬殊,比表面积、XRD、XPS测试结果表明,在较低的反应温度范围内,比表面积大,则晶格畸变率大、晶粒度小,表面未饱和的配位氧量高的MgO有较好的催化性能。

关键词: 甲烷氧化偶联, 氧化镁, 催化剂性能

Abstract: Aseries of MgO catalysts prepared by different methods for the catalytic oxidation coupling of methane were investigated.The specific surface area, XRDand XPSmeasurement results reveal that the catalysts with larger specific surface area, larger lattice distortion, Iess crystal dimension and higher amount of surface unsaturated coordinated oxygen can give higher catalytic activity for the reaction mentioned above at lower temperatures.

Key words: Oxidation coupling of methane, MgO, Properties of catalysts
