Oxidative Coupling of Methane over Lithium Promoted Magnesia

摘要

The direct conversion of methane into ethylene via the oxidative couplingprocess, where methane is converted into ethylene and water with the aid of oxygen in the prescence of a catalyst, is studied. Focus is on the lithium doped magnesia (Li/MgO) catalyst. Attention for the preparation method of this catalyst, the working principle and the influence of this catalyst on the methane conversion are studied extensively. A good insight into the working principle of the catalyst Li/MgO for direct conversion is provided. Li/MgO is shown to offer perspectives for future use provided that improvement of the stability of the catalyst is achieved.
