REGENERATION METHOD FOR ACID-GAS ADSORPTION DEVICE, AND MANUFACTURING METHOD FOR ACID-GAS ADSORPTION DEVICE

WIPO Patent Application WO/2023/195388

A1

Provided are: a regeneration method for an acid-gas adsorption device, the method enabling smooth recovery of acid-gas recovery performance and reduced running costs; and a manufacturing method for an acid-gas adsorption device, the method enabling the manufacture of an acid-gas adsorption device having a superior acid-gas recovery performance. A regeneration method for an acid-gas adsorption device according to an embodiment of the present invention includes: a step in which a gas including an acid gas is supplied to the acid-gas adsorption device so as to contact an acid-gas adsorption layer, causing an acid gas adsorbent to adsorb the acid gas; a step in which the acid gas is desorbed from the acid gas adsorbent; a step in which, after undergoing the step of adsorbing the acid gas and the step of desorbing the acid gas, the acid-gas adsorption layer of the acid-gas adsorption device is removed from the surface of a base material; and a step in which an acid-gas adsorption layer, which includes a porous carrier and the acid gas adsorbent, is formed on the surface of the base material from which the acid-gas adsorption layer has been removed.
