Abstract
This invention relates to a method for catalyzing the reactions QZ+H.sub.2 X.fwdarw.QZX (1) ps and QZX.fwdarw.QZ+H.sub.2 X (2) wherein Q=C or N; Z=O or S; X=O, S, NH or NR; R=C.sub.1 to C.sub.8 alkyl which may be linear, branched or cyclized, which comprises: contacting at least one polydentate nitrogen-containing chelating agent complexed with a metal atom with the reactants of one of said reactions, wherein said contacting takes place in the presence of a means for oxidizing when reaction (1) is catalyzed and in the presence of a means for reducing when reaction (2) is catalyzed.
Claims18
A method for oxidizing carbon monoxide to carbon dioxide, comprising:
- (i) contacting, together, carbon monoxide, a nitrogen-containing chelating agent and water;
- wherein said chelating agent is at least one member selected from the group consisting of methmeoglobin bound to a support, ferric hemoglobin bound to a support, iron-containing porphyrins bound to a support, and sperm whale myoglobin bound to a support, wherein said support is glass, a natural fiber, a synthetic fiber, a gel, charcoal, carbon ceramic material, a metal oxide, a synthetic polymer, a zeolite, a silica compound or an alumina compound;
- and
- (ii) obtaining carbon dioxide.
The process of claim I, wherein said nitrogen-containing chelating agent is methemoglobin.
The method of claim I, wherein said support is glass, a natural fiber, a synthetic fiber or a gel.
A method for oxidizing carbon monoxide to carbon dioxide, comprising:
- (i) contacting, together, carbon monoxide, a nitrogen-containing chelating agent and water;
- wherein said chelating agent is heme bound to a support, or wherein said chelating agent is hemin, and said support is glass, a natural fiber, a synthetic fiber, a gel, charcoal, carbon, a ceramic material, a metal, a metal oxide, a synthetic polymer, zeolite, silica compound or an alumina compound;
- and
- (ii) obtaining carbon dioxide.
