Abstract

Talking about liquid hydrogen as a marketable cryoproduct it’s necessary to consider its potential contamination with micro admixtures, in particular with nitrogen. All known information concerning this matter is very contradictory. In article we obtained by independent original method the experimental data thermodynamically corresponded about dissolubility of solid nitrogen in liquid hydrogen. Within the limits of temperature from 20,3 up to 28,0 K dissolubility varies from 0,45 to 23,4 vppm. At the same time adsorption balances were explored in the system nitrogen – liquid hydrogen – silicagel ACMK-BC, and describes the method for purification of liquid hydrogen from nitrogen admixture. Is paid attention to necessity of an establishment the norms of the contents of nitrogen in liquid hydrogen, which will ensure reliable operation of the equipment.
