Selective removal of oxygen from syngas

A process for converting a hydrocarbon-containing feed gas to liquid hydrocarbon products comprising:

• (a) reacting the hydrocarbon-containing gas and an oxygen-containing gas in a syngas reactor under conditions effective to produce a first syngas stream comprising primarily hydrogen and carbon monoxide with a measurable amount of oxygen;
• (b) passing at least a portion of the first syngas stream in step (a) over a catalyst that promotes a reaction between the unconverted oxygen and carbon monoxide to produce a second syngas stream wherein said second syngas stream comprises less unconverted oxygen than the first syngas stream;
• and
• (c) reacting at least a portion of the second syngas stream of step (b) in a synthesis reactor under conditions effective to produce liquid hydrocarbon products.
