Integrated oxygen generation and carbon dioxide absorption method apparatus and systems

A method for producing oxygen and absorbing carbon dioxide in a single operation comprising:

• providing a solution comprising a permanganate salt, water and hydrogen peroxide;
• allowing said permanganate salt, water and hydrogen peroxide to react to produce manganese (II) ion and oxygen in the presence of a catalyst;
• introducing carbon dioxide gas into said solution;
• contacting said carbon dioxide with said manganese (II) ion;
• and
• allowing manganese carbonate to precipitate.

An apparatus for producing oxygen and absorbing carbon dioxide comprising:

• a tank containing an aqueous solution comprising a chemical species capable of reacting with carbon dioxide to form an insoluble precipitate, an oxygen source and a redox partner, said oxygen source and said redox partner reactable to form oxygen, and said tank comprising a material that does not catalyze the reaction of said oxygen source and said redox partner;
• a catalyst for catalyzing the reaction of said oxygen source and said redox partner positioned in said tank to contact the aqueous solution;
• a carbon dioxide inlet in said tank positioned to introduce carbon dioxide into the solution;
• and
• an oxygen outlet in said tank positioned to allow oxygen gas to escape.

An apparatus for producing oxygen and absorbing carbon dioxide comprising:

• a tank for receiving an aqueous solution, comprising a material that does not catalyze the reaction of permanganate ion with hydrogen peroxide;
• a catalyst for reacting a permanganate salt with hydrogen peroxide to produce oxygen positioned in said tank to contact the aqueous solution when added to said tank;
• a carbon dioxide inlet in said tank positioned to introduce carbon dioxide into the solution when added to said tank;
• an oxygen outlet in said tank positioned to allow oxygen gas to escape;
• and
• at least one plate separating said tank into at least a first and a second fluidly coupled chamber, said first chamber comprising said carbon dioxide inlet and a hydrogen gas outlet and said second chamber comprising said oxygen outlet.

A system for generating power comprising:

• a power generator for generating power or electricity, and
• an integrated oxygen generator/carbon dioxide absorber, said integrated oxygen generator/carbon dioxide absorber providing oxygen to said power generator and absorbing waste carbon dioxide from said power generator;
• said integrated oxygen generator/carbon dioxide absorber comprising:
• a tank comprising a material that does not catalyze the reaction of permanganate ion with hydrogen peroxide,
• an aqueous solution comprising a permanganate salt and hydrogen peroxide contained in said tank,
• a catalyst in contact with said aqueous solution for catalyzing the reaction of said permanganate salt with said hydrogen peroxide to produce oxygen,
• a carbon dioxide inlet in said tank positioned to introduce carbon dioxide into said aqueous solution and
• an oxygen outlet in said tank positioned to allow oxygen gas to escape from said tank.
