초록

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 ...
