摘要： An absorbent according to the present invention absorbs CO2 or H2S contained in flue gas emitted from a power generating plant such as a thermal plant, and contains three or more amine compounds selected from linear or cyclic amine compounds having a primary amino group, and linear or cyclic amine compounds having a secondary amino group. By way of a synergetic effect of the mixture of these compounds, the absorption speed of CO2 or H2S absorption is improved. A small amount of CO2 contained in a large amount of boiler flue gas can be absorbed efficiently.
