ABSTRACT:
A carbon dioxide clathrate having a lump diameter enough to precipitate on a desired abyssal position of the sea without being drifted by a seawater flow of the abyss can be produced by bringing an aqueous solution into contact with carbon dioxide with the interposition of an interface in a reactor and retaining this contact; adjusting the pressure in the reactor to 13 atm or more, the temperature of the aqueous solution to a level of more than 5.degree. C. to 10.degree. C., the temperature of the interface to a level of more than 10.degree. C. to 15.degree. C. and the temperature of a lug inserted into the aqueous solution to a level of more than 0.degree. C. to 5.degree. C.; producing/growing the carbon dioxide clathrate on the lug; and then heating the lug to a temperature of more than 10.degree. C. to 30.degree. C. to separate/drop the carbon dioxide clathrate therefrom.
