摘要:
A process is provided for selectively separating oxygen from an oxygen-containing fluid stream by bringing said fluid stream into contact with a high capacity solid state cyanocobaltate complex in a non-aluminosilicate environment represented by the chemical formula:A.sub.X/Z.sup.Z+ [Co(CN).sub.n ].sup.X- .cndot.pSwhere:A is an alkali, alkaline earth, transition, or Group 12 metal atom;Z is 1, 2 or 3;n is any number from 3 to 5;X is n-2;p is any number from greater than zero to 6; andS is a ligand which is capable of coordinating with A.sup.Z+, Co or both.These complexes chemically bind oxygen to form novel oxygen adducts, thereby selectively removing oxygen from the fluid stream. The bound oxygen may be recovered by increasing the temperature or by reducing the partial pressure of O.sub.2 above the adduct.
