Abstract
A cyclical system that uses a metal hydroxide to produce a metal carbonate, remove carbon dioxide from a waste gas source, and produce more metal hydroxide needed for the beginning of the cycle. Initially, the metal hydroxide is mixed with waste gases in a carbon dioxide scrubber. The scrubber reacts the carbon dioxide with the metal hydroxide to produce a metal carbonate. Some of the metal carbon is removed, therein removing carbon dioxide from the environment. Some of the metal carbonate is heated to produce metal oxide and carbon dioxide. The carbon dioxide is drawn away. Oxygen is introduced into the reaction chamber. The oxygen reacts with the metal oxide to produce an oxidized metal oxide and heat. The oxidized metal oxide is reduced with an acid and volatile base to produce metal hydroxide. The metal hydroxide is recycled. The acid is regenerated. The volatile base is recovered and recycled.
