A METHOD FOR PRODUCING HYDROCARBONS BY OXIDATIVE COUPLING OF METHANE WITHOUT CATALYST

摘要

A method for producing olefins and synthesis gas comprising (a) introducing a reactant mixture to a reactor, wherein the reactant mixture comprises methane (CH4) and oxygen (O2), wherein the reactor is characterized by a reaction temperature of from about 700°C to about 1,100°C; (b) allowing at least a portion of the reactant mixture to react via an oxidative coupling of CH4 reaction to form a product mixture, wherein the product mixture comprises primary products and unreacted methane, wherein the primary products comprise C2+ hydrocarbons and synthesis gas, wherein the C2+ hydrocarbons comprise olefins, and wherein a selectivity to primary products is from about 70% to about 99%; and (c) recovering at least a portion of the product mixture from the reactor.
