[0084] Such as Figure 4 As shown, the separation device 9 of the first embodiment has: a supply device 10 capable of separately supplying protium gas and flowing gas (nitrogen, helium), and passing the helium gas through the water 2 and the empty test tube 3 to supply water vapor. The steam generator 19 is built-in the adsorption tank 11 of the above-mentioned adsorbent material configured in such a way that water vapor or flowing gas passes through, the deuterium concentrated water outlet 12, and the deuterium-depleted water outlet 13 are respectively arranged in the pipeline of nitrogen gas and the pipeline of helium gas And mass flow controllers 17, 18, 20, and valves V1, V2, V3, V4 in the pipeline of protium gas.

[0085] In the first embodiment, first, when the valve V1 and the valve V2 are opened and the valve V3 is operated to open the deuterium concentrated water outlet 12, mass flow controllers 17 and 18 are used to flow from the supply device 10 to the adsorption ta...

[0100] Such as Figure 5 As shown, the second embodiment is characterized by the use of a rotating adsorbent material 14 .

[0101] This separation device 9 has: a supply device 10 capable of supplying water vapor, protium gas, and flowing gas (nitrogen, etc.); 14, deuterium concentrated water outlet 12 and deuterium-depleted water outlet 13.

[0102] The adsorbent 14 is formed in a disk shape or a column shape, and is arranged so that the plane faces the upstream direction and the downstream direction.

[0103] In addition, it is divided into a route for supplying water vapor and flowing gas from the supply device 10 to the adsorbent 14, a route for supplying protium gas, and a route for supplying only dried flowing gas, and these supply ports are aligned along the circumferential direction of the adsorbent 14. configuration. The supply ports for mixed gas, protium gas and flowing gas remain stationary.

[0104] In the second embodiment, the mixed gas of water vapor and f...

Abstract

According to the present invention, water is separated into deuterium-depleted water and deuterium-concentrated water with ease and low cost. This method for producing deuterium-depleted water by removing heavy water and semi-heavy water from water is characterized by: supplying water vapor for a period of time to an adsorbent (11) that is obtained by adding, to a carbon material, at least one ofmetals belonging to Group (8) to (13) of the Periodic Table of the Elements, as an additive metal, and allowing the water vapor to adsorb onto the adsorbent (11) while passing the water vapor throughthe adsorbent (11); then bringing protium gas into contact with the adsorbent (11); and then additionally desorbing the water vapor adsorbed onto the adsorbent (11), and thereby recovering the same.

Description

technical field [0001] The present invention relates to a method for producing deuterium-depleted water in which the amount of heavy water or semi-heavy water is reduced from general water. [0002] In addition, the present invention relates to a method for producing a large amount of deuterium-enriched water containing heavy water and semi-heavy water from general water. Background technique [0003] In normal water, H 2 O (light water), D 2 Mixture of O (heavy water) and / or DHO (semi-heavy water), D 2 O (heavy water) and DHO (semi-heavy water) are water molecules containing deuterium atoms which are isotopes of hydrogen atoms. The concentration of heavy water and semi-heavy water contained in natural water varies depending on the site where it is collected, but it is about 150 ppm in flat land, and most of it is semi-heavy water. [0004] The amount of heavy water and semi-heavy water contained in the human body is as small as 95 ppm of body weight for an adult with a ...
