Title:
METHOD FOR PRODUCING DEUTERIUM-DEPLETED WATER AND METHOD FOR PRODUCING DEUTERIUM-CONCENTRATED WATER
Document Type and Number:
WIPO Patent Application WO/2019/004102
Kind Code:
A1
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 of metals 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 through the 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.
