A metal oxide catalyst capable of catalyzing an oxidative coupling of methane reaction is described. The metal oxide catalyst includes a lanthanum (La) cerium (Ce) metal oxide and further including a lanthanum hydroxide (La(OH)) crystalline phase. The catalyst is capable of catalyzing the production of C+ hydrocarbons from methane and oxygen. Methods and systems of using the metal oxide catalyst to produce C+ hydrocarbons from a reactant gas are also described.

Methane oxidative coupling with La&#x2014;Ce catalysts

Disclosed is a process for producing C+ hydrocarbons, and systems for implementing the process, that includes providing a reactant feed that includes methane and an oxygen containing gas to a first reaction zone, wherein the temperature of the reactant feed is less than 700&#xb0; C. contacting the reactant feed with a first catalyst capable of catalyzing an oxidative coupling of methane reaction (OCM) to produce a first product stream that includes C2+ hydrocarbons and heat, and contacting the first product stream with a second catalyst capable of catalyzing an OCM reaction to produce a second product stream that includes C+ hydrocarbons, wherein the produced heat is at least partially used to heat the first product stream prior to or during contact with the second catalyst, wherein the amount of C+ hydrocarbons in the second product stream is greater than the amount of C+ hydrocarbons in the first product stream.

Low inlet temperature for oxidative coupling of methane

An oxidative coupling of methane (OCM) catalyst composition comprising one or more oxides doped with Ag; wherein one or more oxides comprises a single metal oxide, mixtures of single metal oxides, a mixed metal oxide, mixtures of mixed metal oxides, or combinations thereof; and wherein one or more oxides is not LaOalone. A method of making an OCM catalyst composition comprising calcining one or more oxides and/or oxide precursors to form one or more calcined oxides, wherein the one or more oxides comprises a single metal oxide, mixtures of single metal oxides, a mixed metal oxide, mixtures of mixed metal oxides, or combinations thereof, wherein the one or more oxides is not LaOalone, and wherein the oxide precursors comprise oxides, nitrates, carbonates, hydroxides, or combinations thereof; doping the one or more calcined oxides with Ag to form the OCM catalyst composition; and thermally treating the OCM catalyst composition.

Silver promoted catalysts for oxidative coupling of methane

Methods for making a multilevel core-shell structure having a core/graphene-based shell structure are described. A method for making a core/graphene-based shell structure can include obtaining a composition that includes core nano- or microstructures and graphene-based structures having at least a portion of a surface coated with a curable organic material, where the core nano- or microstructures and graphene-based structures are dispersed throughout the composition and subjecting the composition to conditions that cure the organic material and allow the graphene-based structures to self-assemble around the core nano- or microstructures to produce a core/graphene-based shell structure that has a graphene-based shell encompassing a core nano- or microstructure.
