Abstract

A mixture of Krypton and Xenon is recovered from air by separating into a nitrogen fraction and oxygen fraction, e.g. by liquefaction, and passing the oxygen fraction in the vapour phase at a temperature substantially below atmospheric temperature through an absorbent bed of a zeolite of the "molecular sieve" type, having a pore size such that the Krypton and Xenon are preferentially absorbed and subsequently heating the zeolite to desorb the Krypton and Xenon mixture therefrom. The oxygen fraction is generally not substantially above its boiling point. Suitable examples of zeolites are given and have a pore size of approximately 5 to 13 .
