摘要
在添加了15%Li_2O的NdMO_3(M=Cr、Mn、Fe、Co、Ni)上进行了甲烷氧化偶联(OCM)反应研究.通过改变反应气中CH_4:O_2浓度比,在氧化态和“脱氧态”催化剂上的CH_4脉冲反应,探讨了表面吸附氧和晶格氧在OCM反应中的作用以及NdMO_3中不同金属离子(M)对OCM反应活性的影响等.
AbstractThe oxidative coupling of methane over 15% LitO/NdMO3 (M = Cr ,Mn, Fe, Co ,Ni) was studied by changing the ratio of CH4 to O2 in the reactant gases and using a pulse reaction technique with pure CH4 over oxygenated and deoxygenated catalysts. The rule of the surface adsorbed oxygen and lattice oxygen in the OCM reaction and the effects of M ions in 15% NdMO3 on the OCM reaction were discussed.
