为研制适合于常温催化氧化氚气的催化剂,研制了两种用于氢催化氧化的无机载体疏水催化剂。室温下,催化剂对空气中浓度为0.3%～1%(V/V)氢气的催化氧化转化率都在95%以上,可以用于常温含氚废气的处理。其中Pt-Ⅱ型催化剂催化氢-氚水同位素并流交换的能力明显大于Pt-PTFE(铂-聚四氟乙烯),虽然性能略差于Pt-SDB(铂-聚苯乙烯-二乙烯基苯),但抗压强度大,可用于重水提氚系统CECE单元。
In order to develop a catalyst suitable for tritium gas oxidation at room temperature, two kinds of inorganic carrier hydrophobic catalysts for hydrogen catalytic oxidation were developed. At room temperature, the catalyst has a catalytic oxidation conversion of more than 95% at a concentration of 0.3% -1% (V / V) in air and can be used for the treatment of tritium-containing exhaust gas at room temperature. Among them, the Pt-Ⅱcatalyst is capable of catalysing the cocurrent exchange of hydrogen and tritium water significantly more than that of Pt-PTFE, although its performance is slightly worse than that of Pt-SDB (Pt-polystyrene-divinylbenzene ), But the compressive strength, can be used for heavy water to mention tritium system CECE unit.
