Abstract: The present invention relates to a carbon dioxide capture agent containing two types of amine compounds and a carbon dioxide capture method using the same, by which not only an effective and economically sustainable CO2 capture process can be performed but also an improved reaction rate is achieved.

Abstract: The present invention relates to an absorbent having improved carbon dioxide capture performance of an amine solution to which a reaction accelerator is added and a method for manufacturing the same, specifically relates to an absorbent in which an amine solution is mixed with a primary amine containing an aromatic ring as an active additive that can improve the absorption rate to improve both the absorption performance and the absorption rate, and a method for manufacturing the same.

Abstract: The present invention provides a composite catalyst for diminishing energy demand during carbon dioxide absorbent regeneration and a method for producing the same. The present invention more particularly relates to a composite catalyst in which the surface or inside of activated carbon activated carbon used as a porous carrier is modified with oxides of one or more metals selected from a transition metal group consisting of Fe, Ni, and Mo, and a method for producing the composite catalyst. The activated carbon composite catalyst modified with a metal of the present invention is able to regenerate MEA (monoethanolamine) at a low temperature of 100° C. or below to diminish heat consumption, can decrease the heat duty by increasing the carbon dioxide desorption rate at a low temperature of 100° C.
