Room temperature detritiation technology has been researched and developed to enhance the tritium safety of fusion facilities. The inorganic-based hydrophobic Pt-catalyst has been developed for efficient oxidation of hydrogen isotopes at room temperature, even in the presence of saturated water vapor. The zeolite which framework SiO2/Al2O3 ratio is controlled to be 10 is suitable for water absorbent of room temperature dryer due to excellent detritiation and dehydration performance at room temperature.

为了提高聚变装置的氚安全性，研究和开发了室温氚化技术。基于无机的疏水Pt催化剂已经被开发用于在室温下甚至在饱和水蒸气存在下有效氧化氢同位素。骨架SiO2/Al 2 O3比控制在10左右的沸石，在室温下具有良好的除水和脱水性能，适合作为室温干燥器的吸水剂。
