Abstract
A hydrogen oxidation catalyst is provided, comprising a zeolite that contains at least one catalytically active noble metal or a compound thereof, wherein said zeolite is a hydrophobic zeolite. A use of the catalyst and a method for hydrogen recombination in nuclear power plants, reprocessing plants or fuel element repositories is also specified.
Claims6
A process for hydrogen combination in nuclear power stations, reprocessing plants, or fuel element stores, comprising:
- providing a nuclear power station, a nuclear fuel reprocessing plant or a nuclear fuel element store, in which hydrogen is generated by the contact of nuclear fuel with water, or by the contact of hot metal with water;
- and
- contacting the hydrogen generated in the nuclear power station, the nuclear fuel reprocessing plant or the nuclear fuel element store and oxygen with a catalyst to form water, wherein the catalyst comprises an intrinsically hydrophobic BEA zeolite having a SiO2/Al2O3 ratio greater than 100, the BEA zeolite not being hydrophobicized with an organosilicon compound, the BEA zeolite containing a catalytically-active noble metal.
