Preparation of Impurity Elimination Material for Inert Gas Containing Tritium

In order to eliminate CH₄, steam, O₂ in inert gas, 65%Ni-10%Cu-25%SiO₂ is prepared as impurity eliminating material by sol-gel method. At space velocity 1000 h^-1, when φ=1%CH₄ and φ=1%CO₂ in argon is reforming over the material, the conversion of CH₄ is higher than 81.5%. At space velocity 1000 h^-1, when the material reacts with φ=1%O₂ in argon, the conversion of O₂ is higher than 91.8%. At space velocity 1000 h^-1, when the material reacts with φ=1% steam in argon, the conversion of steam is higher than 91.7%. More experiments show that low concentration CH₄ can also reform with O₂ and steam over the material, and CH₄ can be eliminated by the reforming reaction.
