The invention discloses a
methanol reforming
hydrogen production reactor with flow velocity
distribution uniformity. The reactor comprises an upper cover plate and a lower cover plate, and further comprises the following three cavities: an
evaporation cavity, wherein a through tank is arranged in the middle of a first
graphite plate, an
evaporation plate is arranged below the first
graphite plate,and the
evaporation cavity is formed in the through tank of the first
graphite plate on the evaporation plate; a
combustion cavity, wherein a through tank is arranged in the middle of a second graphite plate, a
combustion reaction plate is arranged below the second graphite plate, and the
combustion cavity is formed in the through tank of the second graphite plate on the combustion reaction plate; and a reforming reaction cavity, wherein a through tank is arranged in the middle of a third graphite plate, and two foam
metal plates and a corrugated plate are arranged in the through tank. Each plate is provided with through holes, so that a
methanol combustion reactant and a
methanol steam reforming reactant respectively circulate through two respective paths. The reactor has the advantagesof good heat-conducting property,
low density, light weight, good sealing property, uniform reactant flow velocity distribution, increase the reactant conversion rate, enhancement of the flow directionality, avoiding of turbulence and enhancement of the
heat transfer and
mass transfer effects.
