REGENERATION METHOD FOR ACIDIC GAS ADSORPTION DEVICE, AND MANUFACTURING METHOD FOR ACIDIC GAS ADSORPTION DEVICE

WIPO Patent Application WO/2023/248967

A1

Provided are: a regeneration method for an acidic gas adsorption device that can reduce running costs; and a manufacturing method for the acidic gas adsorption device. A regeneration method for an acidic gas adsorption device according to an embodiment of the present invention includes: a step for supplying an acidic gas to the acidic adsorption device such that the acidic gas comes into contact with an acidic gas adsorption layer, causing an acidic gas adsorbent to adsorb the acidic gas; a step for desorbing the acidic gas from the acidic gas adsorbent; a step for pulverizing the acidic gas desorption device with which the step for adsorbing the acidic gas and the step for desorbing the acidic gas were carried out, to obtain a recycled powder material; and a step for molding a base material from the recycled powder material, and forming an acidic gas adsorption layer containing an acidic gas adsorbing material on the surface of the base material.
