Abstract
An apparatus for removing free hydrogen from a gas mixture containing essentially hydrogen, oxygen, and steam using a catalyst arrangement for catalytically supported oxidation of hydrogen and a hydrogen-storage apparatus for absorption of hydrogen by hydride formation. The catalyst arrangement and the hydrogen-storage apparatus are designed to operate in different temperature and pressure regions, and they are arranged to provide good heat conduction between them. In this manner, heat generated by hydride formation enhances catalytic oxidation.
Claims16
An apparatus for removing free hydrogen from a gas mixture containing essentially hydrogen, oxygen, and steam, said apparatus comprising:
- a catalyst arrangement having a catalyst material for catalytically supporting oxidation of the hydrogen, and
- a hydrogen-storage device thermally coupled to the catalyst arrangement, said device comprising a container made of a net-like material containing one or more hydrogen-storage materials in the form of plates, granules, chips or a sponge, wherein at temperatures below an effective reaction temperature of the catalyst arrangement said device binds hydrogen by hydride formation and generates heat.
An apparatus for removing free hydrogen from a gas mixture containing essentially hydrogen, oxygen, and steam, said apparatus comprising:
- a catalyst material in the form of granules, chips or powder for catalytically supporting oxidation of the hydrogen,
- a hydrogen-storage material in the form of granules, chips or powder, which at temperatures below an effective reaction temperature of the catalyst material, binds hydrogen by hydride formation and generates heat, and
- a container made of a net-like material containing a mixture of the catalyst material and the hydrogen-storage material.
An apparatus for removing free hydrogen from a gas mixture containing essentially hydrogen, oxygen, and steam, said apparatus comprising:
- a plate coated with a hydrogen-oxidizing catalyst material, and
- a mesh container coupled to the plate and containing a hydrogen-storage material.
