甲烷部分氧化成更有用的化学品，如甲醇，乙烯和苯已被广泛研究，虽然这些产品的产量一直很差1 -4。此外，在这些工艺中的几个中，所需的氧化剂是N2 O而不是O2。本实验室最近的工作表明，在O2存在下，掺锂氧化镁（Li/MgO）具有从CH 4中提取H形成·CH 3自由基的高活性。这表明C2 H6和C2 H4（C2化合物）是通过在该催化剂上形成的两个气态·CH 3自由基之间的偶联产生的。我们在这里报告我们的成功，在传统的催化条件下，以高产率将CH 4转化为C2化合物。
The partial oxidation of methane into more useful chemicals such as methanol, ethylene and benzene has been investigated extensively, although yields for these products have been poor1–4. Moreover, in several of these processes the required oxidant is N2O rather than O2. Recent work5in our laboratory has demonstrated that lithium-doped magnesium oxide (Li/MgO) in the presence of O2has high activity for abstracting H from CH4to form ·CH3radicals. This suggests that C2H6and C2H4(C2compounds) are produced by a coupling between two gaseous ·CH3radicals formed on this catalyst. We report here our success in converting CH4to C2compounds in high yields in conventional catalytic conditions.
