Abstract

See full text

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.
