Abstract

PURPOSE: To concentrate heavy water with good yield by keeping the operating pressure of a high-temperature tower higher than that of a low-temperature tower in the isotope exchange reaction of water-hydrogen system at double temperature over noble metal catalyst supported by a hydrophobic support.
CONSTITUTION: For the isotope exchange reaction of a water-hydrogen system at double temperature over a platinum catalyst supported by a hydrophobic support having a high catalytic activity for the concentration of heavy water, operation is carried out by keeping the operating pressure of a high-temperature tower higher than that of a low-temperature tower, where a low-temperature and low-pressure fluid 13 in a low-temperature and low-pressure tower 11 is then converted into a high-temperature and high-pressure fluid 14 and then directed to a high-temperature and high-pressure tower 12, and also a high-temperature and high-pressure fluid 15 from the high-temperature and high-pressure tower 12 is converted into a low-temperature and low-pressure fluid 16 and then directed to a low-temperature and low-pressure tower 11. Thus, since the transfer rate per unit tower height of heavy hydrogen in the low-temperature tower becomes greater when the pressure of the high-temperature tower is raised and the theoretical possible extraction rate of heavy hydrogen is enhanced, the total volume of exchange tower on the basis of the production rate per unit of time of heavy water is smaller, thus making the amount of catalyst packed lesser and also the operation economical.
