Abstract
Hydrogen generation assemblies, hydrogen purification devices, and their components, and methods of manufacturing those assemblies, devices, and components are disclosed. In some embodiments, the devices may include an insulation base having insulating material and at least one passage that extends through the insulating material. In some embodiments, the at least one passage may be in fluid communication with a combustion region.
Claims18
A steam reforming hydrogen generation assembly configured to receive at least one liquid-containing feed stream that includes water and a carbon-containing feedstock and generate a reformate stream containing hydrogen gas as a majority component and other gases, comprising:
- a vaporization region configured to receive and vaporize at least a portion of the at least one liquid-containing feed stream to form a vapor feed stream;
- a hydrogen-producing region containing a reforming catalyst and configured to receive the vapor feed stream and to produce the reformate stream via a steam reforming reaction;
- and
- a heating assembly configured to produce a heated exhaust stream for heating the vaporization region to at least a minimum vaporization temperature, wherein the vaporization region includes packing material configured to transfer heat from the heated exhaust stream to the at least one liquid-containing feed stream.
A steam reforming hydrogen generation assembly configured to receive at least one feed stream and generate a reformate stream containing hydrogen gas as a majority component and other gases, comprising:
- a hydrogen-producing region containing a reforming catalyst and configured to receive the at least one feed stream and to produce the reformate stream via a steam reforming reaction;
- and
- a heating assembly in thermal communication with the hydrogen-producing region, the heating assembly including an igniter assembly configured to ignite at least one fuel stream, the igniter assembly including an igniter element having a catalytically active coating configured to combust hydrogen in the presence of oxygen.
