CONTAINER FOR HYDROGEN AND ISOTOPES THEREOF Russian patent published in 2010 - IPC G21F5/00 

FIELD: nuclear physics.

SUBSTANCE: invention relates to apparatus for cleaning, storing and supplying gases, mainly hydrogen and its isotopes, as well as helium, argon and other gases. The container comprises a water-cooled sealed case made in form of a cylindrical shell ring with a flange. Both shell rings are sealed onto a water-cooled common flange and the protected zone of the container is made in the gap between the shell rings and the working zone of the container is inside the second shell ring. In the working zone there is a holder with cartridges containing sorbent for hydrogen in form of hydride-forming material. Inside the holder there is a heater. The working zone is linked to gas inlet and outlet pipes. In the gap between the shell rings there is a system for preventing gas from escaping into the surrounding medium. The cartridges contain sorbent in form of 0.4-0.06 mm spherical granules with bulk density of 72-75% of the volume of the cartridge. The granules are made from an intermetallic compound which forms hydrides with hydrogen, where the said hydrides are stable at temperature ranging from 20 to 150°C and decompose with release of gas at temperature ranging from 200 to 550°C, where the intermetallic compound can be an alloy of Zr and Co with cobalt content of up to 50 atomic %. The sorbent is placed in a holder which is made in form of a metal cylinder which has deep slots for placing cartridges on the outer surface in the direction of the axial plane. The width of the slot ranges from 3 to 8 times the diametre of the sorbent granules, and butt-ends of the holder are made in form of radiators.

EFFECT: use of the invention significantly increases specific capacity of the container (approximately 6 times) for absorbing and storing hydrogen with preservation of stability and safety characteristics during prolonged use of the container, ie during repeated hydrogen sorption and desorption processes.
