Comments on the mechanism of oxidative coupling of methane

  • Jae Sung Lee
  • S. Ted Oyama


Fundamental aspects of the mechanism of oxidative methane coupling are treated. The surface has a dual role. In the selective pathway to C2 products it generates methyl radicals which leave the surface to recombine in the gas phase. In the non-selective pathway to COx it catalyzes the oxidation of surface methyl species or C2 products that return to the surface. This mechanism leads to research strategies for selectivity improvement.

Обсуждаются основньіе аспектьі механизма окислительного присоединения метана. Поверхность играет двойную роль. На селективной ступени к C2 продуктам она генерирует метильньіе радикальі, которьіе выделеляются с нее и рекомбинируются в газовой фазе. На нецелективной ступени к COX она катализует окнсление поверхностных метильных частиц или продуктов C2, возвращающихся на поверхность. Этот механизм позволяет разработать стратегию исследований длучшения селективности.
