Many catalysts for steam reforming and the water gas shift are required to be in the reduced form, and can be inactivated by trace oxygen in feeds of fuel or steam. Inactivation of such catalysts by oxygen can be prevented by placing an oxygen-consuming catalyst at or near the inlet end of the reduced catalyst bed, so that any oxygen entering the bed will be reacted with fuel or reformate before reaching the reduced catalyst. This increases the durability of the reduced catalyst. |
