Abstract: Methods and systems are provided for converting methane in a feed stream to acetylene. The method includes processing acetylene as an intermediate stream to form a stream having oxygenates. The hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to oxygenates through subsequent reactors.
