| Research Abstract |
A water-hydrogen chemical exchange column, packed with catalyst and hydrophilic packing in a random manner, was developed for a water detritiation system of a fusion reactor. The optimal value of the catalyst packing ratio was found to be about 30 %. A mass balance model, named "Channeling stage model" was developed for separative analysis of the chemical exchange column. Very large separation factor between hydrogen and tritium was obtained experimentally with a random-packed trickle bed chemical exchange column of 1 m length. The maximum value was 19200 when the flow rate of hydrogen gas was 5 L/min. The absolute value and flow rate dependence of the separative performance were well predicted by the Channeling stage model.
