  • Publication number: 20170190638
    Abstract: A method for producing ethylbenzene (EB) comprising introducing to an oxidative coupling of methane (OCM) reactor an OCM reactant mixture comprising CH4 and O2; allowing the OCM reactant mixture to react via OCM reaction to form an OCM product mixture comprising C2H4, C2H6, water, CO, CO2 and unreacted methane; separating the water and optionally CO and/or CO2 from the OCM product mixture to yield an EB reactant mixture comprising C2H4, C2H6, unreacted methane, and optionally CO and/or CO2; (d) introducing benzene and an EB reactant mixture to an EB reactor; allowing benzene to react in a liquid phase with the ethylene of the EB reactant mixture to form EB; recovering from the EB reactor an EB product mixture comprising EB and unreacted benzene, and an unreacted alkanes mixture comprising C2H6 and unreacted methane, and optionally CO and/or CO2; and optionally recycling the unreacted alkanes mixture to the OCM reactor.

  • Publication number: 20170014807
    Abstract: 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.

  • Publication number: 20160376208
    Abstract: A method for producing olefins comprising (a) introducing to an isothermal reactor a reactant mixture comprising CH4 and O2, wherein the reactor comprises a catalyst bed comprising a catalyst, wherein a catalyst bed temperature is 750-1,000° C., and wherein the reactor has a residence time of 1-100 ms; (b) wherein isothermal conditions minimize hot spots in the bed, thereby decreasing deep oxidation reactions; (c) allowing the reactant mixture to contact the catalyst and react via oxidative coupling of CH4 reaction to form a product mixture comprising C2+ hydrocarbons (olefins and paraffins; C2 hydrocarbons and C3 hydrocarbons) and synthesis gas (H2 and CO), wherein the product mixture has an olefin/paraffin molar ratio of from 0.5:1 to 20:1, and wherein the product mixture has a H2/CO molar ratio of from 0.2:1 to 2.5:1; (d) recovering the product mixture from the reactor; and (e) recovering C2 hydrocarbons and/or synthesis gas from the product mixture.
