Abstract:
A system including an apparatus for removing carbon monoxide from a gas stream passing therethrough, the apparatus comprising:a wheel having a wall formed therein to separate said wheel into a plurality of compartments, each of said plurality of compartments having a catalyst for performing a water gas shift reaction and an adsorbent for adsorbing carbon dioxide and shifting equilibrium towards carbon monoxide consumption; and a valving including a first valve face disposed in a housing adjacent a first major face of said wheel and a second valve face disposed in said housing adjacent a second major face of said wheel; wherein said wheel is rotatable relative to said valving between a first position to permit axial flow through at least one of said plurality of compartments and a first pair of ports in said valving, a second position to permit axial flow through said at least one of said plurality of compartments and a second pair of ports in said valving, a third position to permit axial flow into said at least one of said plurality of compartments through a third port in said valving and a fourth position to permit axial flow from said at least one of said plurality of compartments through a fourth port in said valving.
