Estimating the term…
The present invention involves both separated beds (or physical mixture) and a process for treating a fuel gas comprising sending the fuel gas to a separated bed (or physical mixture), in which the separated beds comprise a first bed of a sulfur sorbent and a second bed of a water gas shift catalyst (a physical mixture of a sulfur sorbent and a water gas shift catalyst). The process comprises first sending the fuel gas to the first bed to remove sulfur compounds from said fuel gas and then the fuel gas goes to the second bed to undergo a water gas shift reaction in which carbon monoxide is converted to carbon dioxide and water is converted to hydrogen (or sending the fuel gas simultaneously to the physical mixture to remove simultaneously the sulfur compounds and to react CO with water to CO2 and hydrogen).
A process for treating a sulfur compound containing gaseous stream comprising contacting said gas with a sulfur sorbent and a water gas shift catalyst under conditions effective for the removal of sulfur with the sulfur sorbent and effective for a water gas shift reaction over the water gas shift catalyst.
A separated bed comprising a bed of a sulfur sorbent adjacent to a bed of a high temperature water gas shift catalyst wherein said sulfur sorbent is selected to remove sulfur from a gaseous stream and said high temperature water gas shift catalyst is selected to be effective for a water gas shift reaction.
