摘要： The embodiment provides a composite that allows the release of acid gas, even the continuous release of acid gas, at low temperature and with a high acid-gas release rate in a regeneration tower of an acid gas removal apparatus, and a regenerator and an acid gas removal apparatus, in both of which the composite is used, and a method of acid gas removal. The composite according to the embodiment is capable of separating an acid gas from an acid gas absorbent, which has absorbed the acid gas, to regenerate the acid gas absorbent, wherein the composite contains an inorganic layered compound and an aluminum-containing oxide. Also provided are a regenerator using the composite to regenerate an acid gas absorbent that has absorbed an acid gas by allowing the acid gas absorbent to release the acid gas, and an acid gas removal apparatus equipped with the regenerator.
