Abstract: The invention relates to a composition containing a catalyst having high catalytic stability for conducting oxidative coupling of methane (OCM) at high carbon efficiency, while improving both methane and oxygen conversion. Particularly, the inventive catalyst is a metal oxide supported catalyst, which contains an alkali metal promoter and a mixed metal oxide component having at least one alkali earth metal and at least one rare earth metal. The metal oxide support is selected in a manner, such that at least a portion of the metal oxide support is capable of reacting with at least a part or whole of the alkali metal promoter under conditions of calcination during catalyst preparation. The invention further provides a method for preparing such a metal oxide supported catalyst composition, using a calcination process. Additionally, the invention further describes a process for producing C2+ hydrocarbons, using such a catalyst composition.

Abstract: A method of selecting a stable mixed metal oxide catalyst for an oxidative coupling of methane (OCM) reaction is disclosed. The method may include, obtaining a mixed metal oxide material having catalytically active metal oxides for the OCM reaction and identifying the Tammann temperature (TTam) of at least one of the catalytically active metals oxides of the mixed metal oxide material. The method further includes selecting the mixed metal oxide material for use as a catalyst in the OCM reaction if the at least one catalytically active metal oxides present in the mixed metal oxide material has a TTam greater than a predetermined temperature.
