Abstract
A method of converting carbon oxides to olefins is provided. The method can include directing a renewable hydrogen feed stream and a carbon oxide feed stream to a methanation reactor to generate an oxidative coupling of methane (OCM) feed stream that includes methane. The OCM feed stream and an oxidant feed stream including oxygen are directed to an OCM reactor containing an OCM catalyst to produce an OCM effluent that includes ethylene. A system for converting carbon oxides to olefins is also provided. The methods and systems produce olefins including ethylene with negative carbon emissions.
