虽然甲烷的催化部份氧化具有潜在的技术上的重要性,但这方面只有少数几篇报道。我们已经报道过,在甲烷的氧化偶联反应中,氧化钐是一种具有活性和选择性的催化剂。一种含有碱金属碳酸盐添加剂的Sm_2O_3能化剂显示出较高催化活性与选择性,能够获得21%的C_2产率。可以认为,甲烷的氧化偶联是从CH_4离解出一个H而生成CH_3基开始的。同样,由两个CH_3基之间偶联生成乙烷。乙烷相继氧化脱氢生成乙烯。通常,自甲烷氧化产生的C_2化合物所
Although the catalytic partial oxidation of methane is potentially of technical importance, there are only a few reports in this area. We have reported that samarium oxide is an active and selective catalyst in the oxidative coupling of methane. A Sm_2O_3 energy agent containing an alkali metal carbonate additive shows a high catalytic activity and selectivity and yields 21% C_2 yield. It is believed that the oxidative coupling of methane begins with the dissociation of CH4 by an H and the formation of CH_3. Similarly, ethane is formed by the coupling between two CH 3 groups. Ethane ethane oxidative dehydrogenation to ethylene. Often, methane is produced from the oxidation of C 2 compounds
