【摘要】 描述了水氢同位素液相催化交换反应的模型,并从动力学和反应过程的角度对模型进行了实验验证。验证结果表明:水氢同位素液相催化交换是一个较复杂的传质反应的串联过程,主要包括汽液相间转化和氢同位素催化交换两个反应。更多还原

【Abstract】 The model of H₂O-H₂ isotopes catalytic exchange reaction was described and proved in terms of dynamics and the process of reaction. The results are shown as following: three-phase （gas/vapour, liquid, solid） coexist in the system of H₂O-H₂ isotopes catalytic exchange reaction. It is a very complex tandem process of the mass transfer and reaction, which mainly involves two steps, one is phase transform between vapour and liquid water in hydrophilic packing; the other is catalytic exchange of hydrogen isotopes in hydrophobic catalyst.更多还原
