Research on the Hydrogen-Deuterium Isotope Exchange Reaction(In Chinese)

The influencing factors of the hydrogen isotopic deuterium from gas to liquid phase are examined by mixed Pt-SDB hydrophobic catalyst and hydrophilic packing.The results show that the exchanged efficiency increases with increasing liquid flux,but the trend is slow down when the liquid flux attains some level.In the same liquid flux,the exchanged efficiency decreases with increasing gas flux,the exchanged efficiency increases with increasing temperature.In the same temperature,the volume transfer coefficient cannot obviously be changed with increasing liquid flux,the influence of the volume transfer coefficient increases with increasing temperature,but the discrepancy of the activation energies between the conditions of high and low gas flux little.
