Title:
METHOD FOR PRODUCING ACIDIC GAS ADSORBENT SHEET, AND ACIDIC GAS ADSORBENT SHEET
Document Type and Number:
WIPO Patent Application WO/2024/071229
Kind Code:
A1
Abstract:
This method for producing an acidic gas adsorbent sheet comprises: step (I) for obtaining a reactant by reacting a compound C1 and a compound C2 in a mixed solution containing the compound C1, the compound C2, and porogen, the compound C1 having a primary amino group, the compound C2 having an epoxy group, and the mixed solution having a primary amino group equivalent greater than an epoxy group equivalent; step (II) for cooling the mixed solution containing the reactant, then adding the compound C2 to the mixed solution, and reacting the reactant and the compound C2 to obtain a reaction solution; step (III) for curing the reaction solution to obtain a sheet-like cured body; and step (IV) for removing porogen from the sheet-like cured body. An acidic gas adsorbent sheet according to the present invention contains a polymer having an amino group, has a carbon dioxide adsorption amount of greater than 0.4 mmol/g, as measured by adsorption test A1, up to 1 hour after the start of the test, and has a carbon dioxide desorption rate of greater than 80% as measured by desorption test B1.
