摘要： 近年来,对天然气的综合利用已逐渐为人们所重视。甲烷氧化偶联制乙烯、乙烷这一新课题受到催化工作者愈来愈多的关注[1~5]。本工作初步探讨了Li-Ln-MgO三元氧化物催化剂对甲烷氧化偶联反应的催化性能。添加稀土元素可使C2的选择性、单收明显提高。本催化剂体系制备简单、原料便宜,值得进一步开发研究。

Abstract: The catalytically oxidative coupling of methane was investigated over Li-Ln-MgO(Ln, La, Ce, Pr, Nd, Sm) in a temperature range of 893~973Kunder atomspheric precsure in a continuous cusitz flew fixed bed reactor. It was found that Li-Ce-MgOoxide catalyst possesses a relative highest selectivity and corresponding higher yield for C2 formation(average value of 30min).
