Abstract: The present invention provides a method for wet-type absorption of carbon dioxide comprising a step of obtaining alkali metal ethyl carbonate sequentially by dissolving alkali metal hydroxide in ethanol and by feeding carbon dioxide in order to be absorbed in a wet-type manner. According to the present invention, even when an alkali metal is used as a main ingredient, a carbonate which is finally produced after absorbing CO_2 is precipitated in a solid form so that the produced carbonate can be easily separated. In terms of CCS techniques, a problem of an existing wet-type absorbing technique based on a solution using alkali metals can be solved. Moreover, in the present invention, solid alkali metal ethyl carbonate reacts with water in order to be converted into liquid ethanol and solid MeHCO_3, so that ethanol can be reproduced or produced through an easy method.

Abstract: The present invention provides a method for wet absorption of carbon dioxide, comprising the step of acquiring an alkali metal ethyl carbonate via the wet absorption of carbon dioxide injected after dissolving an alkali metal hydroxide in ethanol. According to the present invention, the final product of a carbonate after the absorption of carbon dioxide is easy to separate despite using an alkali metal as a raw material because the carbonate is precipitated in a solid state. The present invention can solve the problems of an existing wet absorption technology based on an aqueous solution using an alkali metal from the technical aspect of CSS. Also, the present invention can regenerate or manufacture ethanol easily because the alkali metal ethyl carbonate in a solid state is changed into ethanol in a liquid state and MeHCO3 in a solid state by reacting with water.
