摘要：
Increased selectivity to C-2 hydrocarbons in the oxidative conversion of methane is obtained as a result of the addition of 1-10 wt.% MgO to ZSM-5. Sodium promotion of MgO/ZSM-5 improves the C-2 Selectivity to 100%, but leads to lower stability of the catalyst in the reaction conditions examined. It is established, that the availability of zeolitic basic sites is of great significance for the interpretation of the catalytic activity and selectivity of MgO/ZSM-5 catalysts.
