Abstract:
1. A method for removing carbon monoxide from a hydrogen-rich gas stream produced in a reactor, the method comprising: generating the hydrogen-rich gas stream in a first reactor at a first temperature, comprising one or more catalysts for conducting at least one of a stream reformation reaction, a partial oxidation reaction, or an autothermal reformation reaction of a hydrocarbon feed; passing the hydrogen-rich gas stream from the first reactor through a second reactor at a second temperature that is lower than said first temperature, comprising a vessel which houses: a catalyst consisting essentially of a shift catalyst adapted to perform a water gas shift reaction; and an adsorbent adapted to adsorb carbon dioxide, thereby shifting equilibrium toward carbon monoxide consumption; wherein the vessel is separate from the first reactor and is a rotating pressure swing adsorber.
