  • Patent number: 4547607
    Abstract: A method is disclosed for converting methane to higher hydrocarbon product by contacting the methane with a solid which comprises a reducible metal oxide which when contacted with methane at a temperature within the range of about 500.degree. to 1000.degree. C. is reduced and produces higher hydrocarbon products and water, the improvement comprising recycling C.sub.2 + alkanes recovered during subsequent processing of the effluent produced by the contacting to the contacting step.
