Capture And Sequestration Of Carbon Dioxide In Flue Gases, Surendra Komar Kawatra, Timothy C. Eisele, John J. Simmons

Michigan Tech Patents

There is provided a process for the capture and sequestration of carbon dioxide that would otherwise enter the atmosphere and contribute to global warming and other problems. C02 capture is accomplished by reacting carbon dioxide in flue gas with an alkali metal carbonate, or a metal oxide, particularly containing an alkaline earth metal or iron, to form a carbonate salt. A preferred carbonate for C02 capture is a dilute aqueous solution of additive-free (Na2C03). Other carbonates include (K2C03) or other metal ion that can produce both a carbonate and a bicarbonate salt. Examples of suitable metal oxides include several alkaline …
