Influence of CO2 on the oxidative coupling of methane over a lithium promoted magnesium oxide catalyst

Abstract

Li/MgO catalysts used for the oxidative coupling of methane are found to deactivate relatively rapidly in use; this deactivation can be reversed by treating the the catalyst with CO₂ under the reaction conditions and the deactivation can be avoided completely if CO₂ is added in low concentrations to the reaction mixture.
