The invention relates to a dechlorinating agent used for removing HCl from a gas by using a dry method and a preparation method thereof. The dechlorinating agent is prepared from Na2CO3, CaCO3, CaO and MaO as active constituents, crosslinked bentonite as a porous auxiliary agent, and methyl cellulose as a foaming agent and an auxiliary extrusion agent through extrusion forming, drying and roasting.

By using the crosslinked bentonite as the porous auxiliary agent, the specific surface of the dechlorinating agent is enlarged, and the dechlorinating activity and the chlorosity of the dechlorinating agent are increased. The dechlorinating agent prepared by using the crosslinked bentonite has a pore volume of 0.3-0.4 mL / g, a specific surface of 70-90 m<2> / g and a crushing strength of 60-80 N / cm, not only has lower price than pseudo-boehmite and a molecular sieve, but also has simple preparation process, high dechlorinating activity and great low-temperature penetration chlorosity.
