Abstract
Fuel processing by a reformer (42) and a shift reactor (44) converts hydrocarbon feedstock (12) and steam (36) to hydrogen-rich reformate (11), such as for use in a fuel cell power plant (47). Some of the reformate is recycled through a restriction (18) to the inlet (15) of a feedstock pump (14), thereby increasing its pressure sufficiently to cause recycle flow through a hydrodesulfurizer (21) and the secondary inlet (26) of an ejector (28) driven by the steam (36). Recycle pressure (48) is maintained by steam pressure through a valve (34) regulated by a controller (17).
