Abstract
Included are: a CO2 adsorber 7 including a plurality of adsorption passages 71 allowing exhaust gas to flow through and an adsorbent, on its wall surface, capable of adsorbing and desorbing CO2 depending on a temperature, and a heat exchanger 6 including a plurality of heat exchange passages 61 allowing the exhaust gas to flow through, being disposed in contact with the CO2 adsorber 7, and, when the exhaust gas flows through the heat exchange passages 61, transferring the heat to the CO2 adsorber 7 for heating it while removing the heat of the exhaust gas. The numbers of adsorption cells 72 and heat exchange cells 62 per unit area in a transverse section C are each set to a predetermined number and/or the sizes of the adsorption cell 72 and the heat exchange cell 62 in the transverse section C are each set to a predetermined size.
