Estimating the term…
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 La2O3 alone. 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 La2O3 alone, 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.
An oxidative coupling of methane (OCM) catalyst composition comprising a La—Ce oxide doped with silver (Ag), wherein the Ag comprises Ag nanoparticles, Ag microparticles, Ag nanowires, or combinations thereof;
An oxidative coupling of methane (OCM) catalyst composition comprising a lanthanum (III) and cerium (IV) mixture doped with silver (Ag);
A supported oxidative coupling of methane (OCM) catalyst capable of catalyzing an OCM reaction, the supported OCM catalyst comprising silver (Ag) doped Mn/Na2WO4 and a metal oxide support, wherein the supported OCM catalyst has greater CH4 conversion and C2+ hydrocarbon selectivity as compared to the CH4 conversion and C2+ hydrocarbon selectivity, respectively, of an otherwise similar Mn/Na2WO4 metal oxide supported OCM catalyst that has not been doped with Ag.
