Abstract
A comparative study of the efficiency of the hydrophobic catalyst RCTU-3SM in chemical isotope exchange reactions of hydrogen with water and the oxidation of trace amounts of hydrogen in relation to the detritiation tasks of technological streams was carried out. It is shown that, depending on the equilibrium conditions of the isotope exchange process, there is an optimum temperature at which the reaction rate has a maximum. It was found that the rate of oxidation reaction of trace hydrogen depends on the content of oxygen in the purified stream. With oxygen concentration reducing, the oxidation rate initially increases, and when the ratio of oxygen and hydrogen concentrations is less than 100, the rate remains constant within the experimental error.

疏水性催化剂 RCTU-3SM 在氢气和水蒸气的同位素交换反应和气流中痕量氢气的氧化反应中的性能比较
摘要
对疏水性催化剂 RCTU-3SM 在氢与水的化学同位素交换反应和痕量氢的氧化与工艺流的脱除任务相关的效率进行了比较研究。结果表明,根据同位素交换过程的平衡条件,存在反应速率最大的最佳温度。发现痕量氢的氧化反应速率取决于纯化流中氧的含量。随着氧浓度的降低,氧化速率开始增加,当氧和氢浓度的比值小于 100 时,速率在实验误差范围内保持不变。
