Document Type and Number:
WIPO Patent Application WO/2023/063051
Kind Code:
A1
Abstract:
The present invention provides an acidic gas adsorbent which is suitable for performing adsorption and desorption of an acidic gas under relatively mild conditions. An acidic gas adsorbent according to the present invention contains a polymer P which has an amino group. The density of elemental nitrogen in the acidic gas adsorbent is higher than 12.0 mmol/g. If the acidic gas adsorbent is subjected to an adsorption test A1, the adsorption a1 of carbon dioxide is 0.35 mmol/g or more. If the acidic gas adsorbent is subjected to a desorption test B1, the desorption b1 of carbon dioxide is 0.2 mmol/g or more.
