NOVELTY - Converting natural gas to hydrocarbon liquids includes conveying feed stream comprising light hydrocarbon gas or vapor to a reactor to form a reactive product stream comprising hydrogen and reactive products comprising acetylene and/or ethylene; quenching the reactive product stream; separating an acetylene rich stream and a light gas stream; conveying the acetylene rich stream to a hydrogenation reactor; reacting acetylene and hydrogen; conveying a portion of the hydrogenation reactor effluent comprising ethylene to a catalytic liquefaction reactor (30) to produce hydrocarbon liquids.    USE - Method for converting natural gas to hydrocarbon liquids (claimed).    ADVANTAGE - The method is integrated, energy-efficient for converting natural gas to readily transportable upgraded liquids.    DETAILED DESCRIPTION - Converting natural gas to hydrocarbon liquids comprises:    (A) providing a natural gas stream;    (B) separating from the natural gas stream a methane rich stream and a methane lean stream;    (C) providing a feed stream comprising light hydrocarbon gas or vapor;    (D) conveying the feed stream to a reactor where the feed stream is heated to a temperature and for a time sufficient to form a reactive product stream comprising hydrogen and reactive products comprising acetylene and/or ethylene;    (E) quenching the reactive product stream;    (F) separating from the reactive product stream an acetylene rich stream and a light gas stream;    (G) conveying the acetylene rich stream to a hydrogenation reactor;    (H) reacting acetylene and hydrogen in the hydrogenation reactor to form ethylene;    (I) conveying a portion of the hydrogenation reactor effluent comprising ethylene to a catalytic liquefaction reactor (30) and operating the catalytic liquefaction reactor such that hydrocarbon liquids are produced; and    (J) conveying the hydrocarbon liquids to storage or transport.
