摘要：

In this work, experimental and mathematical substantiation of the possibility of using the new RCTU-4 hydrophobic catalyst [0.9 mass % Pt/styrene and divinylbenzene (SDVB)] in the separation of protium-tritium isotopic mixtures by a two-temperature catalytic exchange method in a water-hydrogen system was carried out. Variation of the synthesis parameters of the support and the catalyst allowed a significant increase in the activity (>= 50 s(-1)) and heat resistance (approximate to 550 K) of the investigated sample compared to the previously used catalyst RCTU-3SM (k(exp) = 12 s(-1); heat resistance = 388 K). The mathematical model presented in the paper considers three phases (liquid water, steam, and hydrogen gas) and allows optimization of dual-temperature installations in the water-hydrogen system for any isotopic mixtures.
