The present invention provides a removing agent for reducing and removing halogen gas such as chlorine in exhaust gas, a manufacturing method thereof, a halogen gas removing method using the same, and a system for removing halogen gas. A halogen gas remover, which contains at least pseudoboehmite as a host material and a sulfur-containing reducing agent as a guest material. Preferably, based on the total amount of pseudoboehmite and sulfur-containing reducing agent, 1 wt% to 8 wt% of reducing agent is included in terms of sulfur element, and it is more preferred to further include alkaline earth metal elements and transition metal elements. , At least one inorganic compound selected from oxides, carbonates, and hydrocarbons of zinc group elements is used as the third component. |
