Abstract
Drastic changes in nature and surface composition of lithium promoted magnesia are shown to occur in the course of the oxidative coupling of methane, together with changes in kinetics. Thus, the fresh material with a large and heterogeneous surface promotes the total oxidation of methane into CO, CO 2 while the aged catalyst, sintered, partially decarbonated and coated by an alkali film leads preferentially to dimerization products. On the basis of the above features, the nature, role and fate of the active sites for methane conversion are discussed, aiming at possible catalyst improvements.
