METHOD FOR THE PRODUCTION OF HYDROGEN-ENRICHED SYNGAS

摘要

Provided is a process for the production of hydrogen-enriched synthesis gas by a catalytic water-gas shift reaction operated on a raw synthesis gas. The process includes introducing a gaseous flow that includes at least one compound of formula (I) as defined herein in a first reactor containing including at least one metal selected from groups VI B and VII of the periodic table. The process also includes collecting a sulfur-containing gaseous flow from the first reactor, introducing the raw synthesis gas in a second reactor, and introducing the sulfur-containing gaseous flow in the second reactor, where the catalytic water-gas shift reaction takes place and includes a sulfur-resistant shift catalyst X2, the sulfur-containing gaseous flow being introduced in the second reactor either directly through flow and/or after mixture through flow with the raw synthesis gas. The process also includes collecting an outlet flow from the second reactor containing hydrogen-enriched synthesis gas.
