摘要
High efficiency processes for producing olefins alkynes and hydrogen co production from light hydrocarbons are disclosed. In one version the method includes the steps of combusting hydrogen and oxygen in a combustion zone of a pyrolytic reactor to create a combustion gas stream transitioning a velocity of the combustion gas stream from subsonic to supersonic in an expansion zone of the pyrolytic reactor injecting a light hydrocarbon into the supersonic combustion gas stream to create a mixed stream including the light hydrocarbon transitioning the velocity of the mixed stream from supersonic to subsonic in a reaction zone of the pyrolytic reactor to produce acetylene and catalytically hydrogenating the acetylene in a hydrogenation zone to produce ethylene. In certain embodiments the carbon efficiency is improved using methanation techniques.
