Abstract
A method of performing an oxidative coupling of methane (OCM) reaction to produce C2+ compounds using a low temperature gas mixture feed is provided. The method includes introducing a gas mixture feed containing methane, oxygen, hydrogen, and carbon monoxide at a temperature of less than or equal to 300° C. to an inlet of an OCM reactor, which contains a combustion catalyst and an OCM catalyst. At least a portion of the gas mixture feed is combusted using the combustion catalyst to generate a heated gas mixture having a temperature of at least 450° C. The heated gas mixture contacts the OCM catalyst to initiate an OCM reaction and produce an OCM effluent that includes C2+ compounds. A system for performing an OCM reaction using a low temperature feedstock gas mixture is also provided.
