Abstract: A carbon dioxide separation recovery method includes: bringing a particulate carbon dioxide adsorbent and a treatment target gas containing carbon dioxide into contact with each other to make the carbon dioxide adsorbent adsorb the carbon dioxide contained in the treatment target gas; and bringing the carbon dioxide adsorbent which has adsorbed the carbon dioxide and superheated steam into contact with each other to desorb the carbon dioxide from the carbon dioxide adsorbent and thereby regenerate the carbon dioxide adsorbent, and recovering the desorbed carbon dioxide. A saturation temperature of the superheated steam which is brought into contact with the carbon dioxide adsorbent is not more than a temperature of the carbon dioxide adsorbent which contacts the superheated steam. The regenerated carbon dioxide adsorbent is utilized for adsorption of the carbon dioxide again without being subjected to a drying step.
