Abstract: A catalyst composition, suitable for producing ethylene and other C2+ hydrocarbons from methane. The composition includes a blended product of two distinct catalyst components, blended at such synergistic proportions, that results in a catalyst having high C2+ hydrocarbon selectivity while maintaining an overall sufficient catalyst activity and low ethyne selectivity. Methods for preparing such a catalyst composition and a process for producing C2+ hydrocarbons using such a catalyst composition are provided.

Abstract: The invention relates to a composition containing a catalyst suitable for producing ethylene and other C2+ hydrocarbons at high selectivity while improving both methane conversion and product yield. Particularly, the catalyst contains mixed metal oxides having at least one alkali earth metal and at least one rare earth metal along with an alkali metal promoter in the form of an alkali metal or in the form of an alkali metal tungstate. The invention further provides a method for preparing such a composition, using a calcination process to calcine the alkali metal promoters together with mixed metal oxides. Additionally, the invention further describes a process for producing C2+ hydrocarbons, using such a composition.
