Abstract
Official abstract text for this publication.
A method of processing synthesis gas improves the quality of the synthesis gas by using a water gas shift reaction to increase the molar ratio of hydrogen to carbon monoxide (H 2 :CO) in an efficient manner. A first steam of hot natural gas-based synthesis gas having a first higher molar ratio of H 2 :CO is combined with a second stream of quenched synthesis gas having a second lower molar ratio of H 2 :CO to provide a blend of synthesis gas having a third molar ratio of H 2 :CO that is between the first and second molar ratios. A non-catalytic water gas shift reaction increases the molar ratio of H 2 :CO to a fourth molar ratio that is higher than the third molar ratio, and can be about equal to or greater than the first molar ratio without supplying external heat.
First claim
Opening claim text (preview).
We claim: 1. A method of processing synthesis gas, comprising the steps of: providing a first stream of natural gas-based synthesis gas provided at a temperature of at least about 1750° F. having a first molar ratio of H 2 :CO; providing a second stream of synthesis gas provided at a temperature less than about 1000° F. having a second molar ratio of H 2 :CO that is lower than the first molar ratio of H 2 :CO; combining the first and second streams of synthesis gas in a therma…
