A supported catalyst and preparation method thereof, the catalyst comprising an organic polymer material carrier and Raney alloy particles supported on the organic polymer material carrier, wherein substantially all of the Raney alloy particles are partially embedded in the organic polymer material carrier. The catalyst can be used in hydrogenation, dehydrogenation, amination, dehalogenation or desulfuration reactions.

Integrated systems are provided for the production of higher hydrocarbon compositions, for example liquid hydrocarbon compositions, from methane using an oxidative coupling of methane system to convert methane to ethylene, followed by conversion of ethylene to selectable higher hydrocarbon products. Integrated systems and processes are provided that process methane through to these higher hydrocarbon products.

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.
