Abstract
The present invention is an improvement in the preparation of liquid hydrocarbons from natural gas/methane, oxygen and/or steam. In particular, the present invention relates to processes for the production of synthesis gas, reducing the oxygen concentration from the synthesis gas, and the production of liquid hydrocarbons using the oxygen reduced synthesis gas as a feedstock. More particularly, the present invention described herein identifies catalyst compositions, apparatus and methods of using such catalysts and apparatus for preparing liquid hydrocarbons via oxygen reduced synthesis gas all in accordance with the present invention.
Claims35
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) removing oxygen from the first syngas stream by 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.
