Claim 21:
22. A method for producing hydrogen in a water gas shift (WGS) reactor, the method comprising:
flowing a cooling fluid through a cooling fluid channel defined between a housing of a WGS reactor and each of multiple reaction tubes disposed in the housing; and
flowing a gas comprising carbon monoxide and steam through each of multiple reaction channels, each reaction channel defined within a corresponding one of the reaction tubes, in which an inlet of each reaction channel and an outlet of the cooling fluid channel are disposed at a first end of the WGS reactor;
in which flowing the gas through each of the reaction channels comprises:
flowing the gas across a heat transfer material disposed in each reaction channel to transfer heat from the flowing gas to the cooling fluid in the cooling fluid channel, comprising reducing the temperature of the flowing gas to a temperature at which the catalyst structure catalyzes the hydrogen generation reaction, in which the temperature is between 200° C. and 450° C.; and
flowing the gas across a catalyst disposed in each reaction channel, the catalyst configured to catalyze a hydrogen generation reaction.
