AI Technical Summary
Technical Problem
The CO2 adsorbent in CO2 adsorbers experiences reduced performance due to temperature rise, and the H2O adsorbent generates heat, increasing the temperature of the exhaust gas and affecting CO2 removal efficiency.
Method used
A CO2 recovery device with a first cooling unit, H2O recovery unit, and CO2 recovery unit, utilizing pumps for desorption and storage, along with a control unit to manage adsorption and desorption modes, effectively cools and separates CO2 and H2O from exhaust gas.
Benefits of technology
The device suppresses the rise in temperature of the CO2 adsorbent, enhancing its performance and ensuring effective removal of CO2 and H2O, with the control unit enabling continuous operation and efficient switching between modes.

Abstract
This suppresses the decrease in CO2 adsorption performance of CO2 adsorbents. [Solution] The CO2 recovery device is configured to recover CO2 from exhaust gas from an internal combustion engine and comprises a first and second cooling unit, an H2O recovery unit, and a CO2 recovery unit. The H2O recovery unit is configured to recover H2O from the exhaust gas by adsorbing the H2O contained in the exhaust gas cooled in the first cooling unit with an H2O adsorbent. The CO2 recovery unit is configured to recover CO2 from the exhaust gas by adsorbing the CO2 contained in the exhaust gas cooled in the second cooling unit after H2O has been recovered in the H2O recovery unit, using a CO2 adsorbent.
