Patent ID: 7915466

Claim:
A method for converting gas comprising hydrocarbons to hydrocarbon liquids, comprising: providing a feed stream comprising light hydrocarbon gas or vapor; conveying the feed stream to a reactor wherein the feed stream is incompletely combusted, and the un-combusted portion of the of 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, ethylene, or both; quenching the reactive product stream; separating from the reactive product stream an acetylene rich stream and a light gas stream; conveying the acetylene rich stream to a hydrogenation reactor; reacting the acetylene rich stream and hydrogen in the hydrogenation reactor to form ethylene; conveying a portion of the hydrogenation reactor effluent comprising ethylene to a catalytic liquefaction reactor and operating the catalytic liquefaction reactor such that hydrocarbon liquids are produced; separating a gas or vapor from the hydrocarbon liquid, separating a liquid stream from the hydrocarbon liquid or both separating a gas or vapor from the hydrocarbon liquid and a stream of liquid from the hydrocarbon liquid; using at least a portion of the gas or vapor stream, at least a portion of the liquid stream or both a portion of the gas or vapor stream and a portion of the liquid stream to at least partially quench the reactive product stream or recirculating at least a portion of the gas or vapor to the reactor, to the catalytic liquefaction reactor, or to both the reactor and to the catalytic liquefaction reactor; and conveying the hydrocarbon liquids to storage or transport.
