REVERSIBLE OXYGEN SORBENT COMPOSITIONS

摘要

High capacity solid state cyanocobaltate complexes represented by the chemical formula: where: A is alkali metal atom, alkaline earth metal atom, Zn, Cd or Hg atom; a is any number from 0 to 2.5 each R is independently C1-C10 substituted or unsubstituted alkyl, aryl or aralkyl; or a long chain hydrocarbon polymer b is any number from greater than zero to 3 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; and S is a ligand which is capable of coordinating with [(A)a(R4N)b], Co or both. are capable of chemically binding oxygen to form novel oxygen adducts, thereby selectively removing oxygen from an oxygen-containing fluid stream. The bound oxygen may be recovered from the complexes by increasing the temperature or by reducing the partial pressure of O2 above the adduct.
