Abstract
1) A first amine, which is a straight chain secondary monoamine, 2) a second amine, which is a cyclic secondary polyamine as a reaction accelerator, and 3) a third amine, which is an amine consisting of one selected from a cyclic amine group constituted from a secondary or tertiary amino group or a straight chain amine group with high steric hindrance are mixed to obtain an absorbent. By the synergistic effect thereof, absorption properties to CO2 and/or H2S are excellent and the absorbed CO2 or H2S emission properties during the regeneration of the absorbent become excellent. Therefore, the water vapor amount used during the regeneration of the absorbent in CO2 recovery equipment can be reduced.
