Beschreibung
Zusammenfassung:	A carbon dioxide adsorbent including silica gel and an amine compound carried by the silica gel. The silica gel has a spherical shape, a particle size ranging from 1 mm to 5 mm inclusive, an average pore diameter ranging from 10 nm to 100 nm inclusive, a pore volume ranging from 0.1 cm3/g to 1.3 cm3/g inclusive, and a waterproof property N that is defined by an expression (1) and that is not lower than 45%,N=(W/W0)×100 (1)whereN is the waterproof property in percentage (%) of the silica gel,W0 is a total number of particles of the silica gel immersed in water,W is a number of particles of the silica gel not subjected to breakage out of W0.
