Investigation of Low Temperature Methane Oxidative Coupling Catalyst

Since it was first reported by Keller and Bhasin in 1982 that ethane and ethylene could be produced through direct oxidation of methane, methane oxidative coupling (MOC) has attracted increasing interest in the world. By now some highly efficient catalysts have been explored such as Li/MgO, LaO, and [Th, La]O, and Cyields can reach 15—20％. However, such high yields are obtained at the high temperature of 700—800℃. The kinetic and mechanism studies show that at such high temperature the
