Abstract:
A thermosiphon shift reactor for conversion of carbon monoxide and generation of steam for use in a fuel processor comprising:a vertically extended shell defining an interior volume containing a vertical axis defining a catalyst zone, said catalyst zone comprising a shift catalyst that extends along a vertical length, said vertically extended shell having a gas inlet at a top end and a gas outlet at a bottom end opposite; an external jacket sealingly surrounding the vertically extended shell parallel to the catalyst zone and defining a flow passage between the vertically extended shell and the external jacket, said external jacket having a fluid inlet in proximity of the bottom end and a fluid outlet opposite; a fluid reservoir disposed above the top end at a height effective to provide thermosiphon circulation through said flow passage, said fluid reservoir having an inlet conduit in fluid communication with the fluid outlet, a water supply inlet, and an outlet conduit in fluid communication with the fluid inlet of the external jacket; and an insulating layer disposed on the vertically extended shell within the flow passage.
