A reformer for producing a hydrogen-rich gas includes a first zone, a second zone, a third zone, a fourth zone and a product gas collection space. The zones are sequentially adjacent. A flow path is provided for directing flow of a reaction stream in diverging directions from the first zone into the second zone, and continuing in the same general diverging directions through the second zone, third zone, and fourth zone. Directing the flow in diverging directions permits flow into and through a zone over more that just a single cross-sectional geometry of the zone or a single cross-section of the flow path transverse to the direction of flows. This configuration can be used to require a lower pressure for flowing the reaction stream so as to reduce the parasitic requirements of the reactor, and can also be used to increase throughput of the reactor.
