The invention belongs to the technical field of dechlorination agent preparation, and particularly relates to a dechlorination agent and a preparation method and application thereof. The raw materials comprise an X-type molecular sieve, an alkali metal compound, an alkaline earth metal compound, a binder and a pore structure modifier; the pore structure modifier is at least one of citric acid, tartaric acid, ethylenediamine tetraacetic acid, oxalic acid, carboxylic acid or salt compounds formed by the carboxylic acid. The dechlorinating agent is a gas-phase dechlorinating agent, has a good dechlorinating effect particularly in the fields of dechlorination of propylene products prepared by propane dehydrogenation and the like, can selectively adsorb inorganic chlorine under the condition of high hydrogen sulfide, and has the dechlorinating precision of less than 0.5 ppm. |
