A COMBINED REFORMER AND SHIFT REACTOR A combined reformer and shift reactor (310) comprises a cylindrical reforming chamber (322) arranged within, and on the axis (320), of a cylindrical vessel (318). An annular steam generator (316) is arranged within, and coaxially with, the vessel (318). The steam generator (316) is arranged around the reforming chamber (322). A plurality of shift reactors (314) extend axially, with respect to the vessel (318), through the steam generator (316). Methane and steam are supplied via helically coiled pipe (368) to the reforming chamber (322) and air is supplied via helically coiled pipe (370). The methane and steam mixture and air flowing through the pipes (368,370) are preheated by the reforming chamber product gases flowing in annular passage (360). The shift reactors (314) convert carbon monoxide and water in the product gases to carbon dioxide and hydrogen and the heat produced is transferred to the water in the steam generator (316) to produce steam. |
