| 1. A reactor for the selective oxidation of carbon monoxide in a hydrogen rich reformate stream, comprising:
a reactor body;
an inlet for the addition of a reformate stream to the reactor body;
at least one oxygen inlet for the addition of oxygen to the reformate stream;
a first catalyst suitable for selective oxidation of carbon monoxide, located within the reactor body;
a second catalyst suitable for selective oxidation of carbon monoxide, located within the reactor body;
a first heat exchanger, having an inlet and an outlet, for removing heat from the first catalyst and the reformate;
a first stream of water flowing through the first heat exchanger;
a second heat exchanger, having an inlet and an outlet, for removing heat from the second catalyst and the reformate;
a second stream of water flowing through the second heat exchanger;
wherein the first stream of water enters the first heat exchanger at least partially as liquid water; and
the second stream water enters the second heat exchanger at least partially as liquid water;
wherein said first stream of water and second stream of water are two phase mixtures of water and steam throughout at least
a portion of the reformate flow path.
