Reactor for producing hydrogen from hydrocarbon fuels

Reacteur pour la production d'hydrogene a partir de combustibles hydrocarbones

Abstract

A reformer reactor (10) for producing a hydrogen-rich gas includes a first zone (18), a second zone (20), a third zone (22), a fourth zone (24) and a product gas collection space (40). The zones are sequentially adjacent. A flow path P1 is provided for directing flow of a reaction stream in diverging directions from the first zone (18) into the second zone (20), the flow of the reaction stream continuing in the same general diverging directions through the second zone (20) and into and through the third and fourth zones (22, 24). Directing the flow in diverging directions permits flow into and through a zone over more than 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. This configuration can also be used to increase throughput of the reactor.
