A method for regenerating an amine-based, acid gas absorbent using a mixed catalyst containing silver oxide and silver carbonate includes the steps of absorbing an acid gas into an acid gas absorbent having an amine group to obtain an acid gas-absorbed absorbent; and regenerating the amine-based, acid gas absorbent by adding a catalyst mixture containing silver oxide and silver carbonate to the acid gas-absorbed absorbent and by removing the acid gas at a temperature ranging from 40&#xb0; C. to 86&#xb0; C. When the amine-based acid gas absorbent is an acid gas absorbent solution and when the acid gas that is absorbed into the acid gas absorbent solution is carbon dioxide, the catalyst mixture efficiently promotes decomposition of carbon dioxide-bound carbamate in the acid gas absorbent solution that absorbs the carbon dioxide through a novel catalytic reaction pathway.

An apparatus and process are provided for electricity production and high-efficiency trapping of carbon dioxide, using carbon dioxide within combustion exhaust gas and converging technologies associated with a carbon dioxide absorption tower and a generating device using ions which uses a difference in concentration of salinity between seawater and freshwater. It is expected that enhanced electrical energy production efficiency, an effect of reducing costs for the operation of a carbon dioxide trapping process, and electricity production from carbon dioxide, which is a greenhouse gas, can be simultaneously achieved by increasing the difference in concentration using an absorbent for absorbing carbon dioxide.

Carbon dioxide trapping device and method capable of producing electricity

A carbon dioxide capturing apparatus and process uses a self-generating power means that uses carbon dioxide in combustion exhaust gas through the convergence of a carbon dioxide absorption tower. The capturing apparatus and process also relies on ionic generator associated technology using a concentration difference between seawater and freshwater. The capturing apparatus and process result in increased production efficiency for electric energy and reduced costs for a carbon dioxide capturing process by increasing a concentration difference using an absorbent liquid for absorbing carbon dioxide and, at the same time, electricity is obtained through carbon dioxide which is a greenhouse gas.

Provided is an absorbent for capturing carbon dioxide. The absorbent may include an amino acid with multiple amine groups and an alkali-metal hydroxide mixed with the amino acid and thus, may increase an absorption capacity for carbon dioxide. When a sterically hindered effect is induced to the amino acid with multiple amine groups, the absorption capacity for carbon dioxide may increase and heat of absorption reaction may decrease and thus, energy consumed for regeneration of an absorbent may be reduced. The absorbent for capturing carbon dioxide may include amino acid with multiple amine groups and the metal hydroxide, and may provide a functional group around the amine groups to cause an sterically hindered effect and thus, the absorption capacity for carbon dioxide and an carbon dioxide absorption rate may increase, and the capital cost for a carbon dioxide capturing process and an operating cost may be significantly reduced.
