OXYGEN/NITROGEN PRODUCTION WITH MOLTEN ALKALI SALTS

摘要

Method of separating oxygen or nitrogen from air using as an oxygen acceptor composition a molten solution of alkali metal salt of a cation composition of sodium and potassium cations and an anion composition of 50 to 94% nitrate, 4 to 25% nitrite and combined oxide, peroxide and superoxide wherein said oxides are present in less than 1 mol % based on sodium peroxide.
