【摘要】 采用Pt-SDB疏水催化剂和亲水填料混装进行含氘、氚氢气与水的液相催化交换实验,研究反应温度、气体流量和液体流量对D、T转化率以及H-D、H-T的总传质系数Kya的影响。研究结果表明:在相同操作条件下,T的转化率η(H-T)比D的转化率η(H-T)高,H-T的总传质系数比H-D的高;从D、T转化率随气体流量和液体流量的变化趋势可知,气体流量对D、T转化率的影响较大;选择合适的反应温度即可获得较佳的转化率和总传质系数。在实际工艺中,反应温度选为45℃较适宜。更多还原

【Abstract】 The hydrogen isotopic deuterium and tritium from gas phase to liquid phase by hydrogen-water exchange were experimentally researched with mixture of hydrophobic catalyst and hydrophillic packing in catalytic bed.The transformation rate and volume transfer coefficient of D and T were determined at various temperature,gas and liquid flow rates.The results show that the transformation rate η(H-T) of T is higher than η(H-D) of D,and the volume transfer coefficient Kya(H-T) of H-T is higher than Kya(H-T) of H-D,the preferable transformation rate and volume transfer coefficient can be obtained by choosing suitable operational temperature.45 ℃ is the suitable operational temperature in practical technique.更多还原
