Abstract: A method of regenerating an acid gas adsorption device includes the steps of: causing an acid gas to be adsorbed to an acid gas adsorption material by supplying a gas including the acid gas to an acid gas adsorption device so that the gas is brought into contact with an acid gas adsorption layer; causing the acid gas to be desorbed from the acid gas adsorption material; removing the acid gas adsorption layer of the acid gas adsorption device, which has been subjected to the step of causing the acid gas to be adsorbed and the step of causing the acid gas to be desorbed, from a surface of a base material; and forming an acid gas adsorption layer including a porous carrier and an acid gas adsorption material on the surface of the base material from which the acid gas adsorption layer has been removed.
