  • Patent number: 11607657
    Abstract: An apparatus for the production of hydrogen from a fuel source includes a combustor configured to receive a combustor fuel and convert the combustor fuel into a combustor heat; a reformer disposed annularly about the combustor, a removable structured catalyst support disposed within the gap and coated with a catalyst to induce combustor fuel combustion reactions that convert the combustor fuel to the combustor heat, and a combustor fuel injection aperture configured for mixing combustion fuel into the combustion catalyst. The combustor fuel injection aperture being disposed along a length of the combustion zone. The reformer and the combustor define a gap therebetween and the reformer is configured to receive the combustor heat.

  • Patent number: 11383978
    Abstract: A heat integrated steam reformer, which incorporates a catalytic combustor, which can be used in a fuel processor for hydrogen production from a fuel source, is described. The reformer assembly comprises a reforming section and a combustion section, separated by a wall. Catalyst (21) able to induce the reforming reactions is placed in the reforming section, either in the form of pellets or in the form of coating on a suitable structured catalyst substrate such as fecralloy sheets. Catalyst (22) able to induce the combustion reactions is placed in the combustion section in the form of coating on suitable structured catalyst substrate such as fecralloy sheet. A steam and fuel mixture (30) is supplied to the reforming section (14) where it is reformed to produce hydrogen. A fuel and an oxygen (32) containing gas mixture is supplied to the combustion section where it is catalytically combusted to supply the heat for the reformer.

  • Patent number: 11305250
    Abstract: A highly compact heat integrated fuel processor, which can be used for the production of hydrogen from a fuel source, suitable to feed a fuel cell, is described. The fuel processor assembly comprises a catalytic reforming zone (29) and a catalytic combustion zone (28), separated by a wall (27). Catalyst able to induce the reforming reactions is placed in the reforming zone and catalyst able to induce the combustion reaction is placed in the combustion zone, both in the form of coating on a suitable structured substrate, in the form of a metal monolith. Fe—Cr—Al—Y steel foils, in corrugated form so as to enhance the available area for reaction, can be used as suitable substrates. The reforming and the combustion zones can be either in rectangular shape, forming a stack with alternating combustion/reforming zones or in cylindrical shape forming annular sections with alternating combustion/reforming zones, in close contact to each other.
