[54] A PROCESS FOR INCREASING THE HYDROGEN CONTENT OF A SYNTHESIS GAS MIXTURE
[57] Abstract: A process is described for increasing the hydrogen content of a synthesis gas mixture comprising hydrogen, carbon oxides and steam, comprising the steps of:(i) passing the synthesis gas mixture at an inlet temperature in the range 300-450oC over a first water-gas shift catalyst disposed in a first shift vessel to form a first shifted gas mixture, and(ii) passing the first shifted gas mixture at an inlet temperature in the range 170-300oC over a second water gas shift catalyst disposed in a second shift vessel to form a second shifted gas mixture, wherein the second water-gas shift catalyst comprises copper and the first shift vessel contains a sorbent material for capturing halogen contaminants disposed downstream of the first water gas shift catalyst.
