The invention discloses a mercury removing agent and a preparation method and application thereof. The mercury removing agent comprises the following components based on the total dry weight of the mercury removing agent: 1-20wt% CuS, 1-10wt% S, 0.1-1wt% adsorption aid, 0.1-1wt% cerium salt, and the balance is carrier; wherein: the ratio of the number of S atoms and Cu atoms is (1.5-5):1; the pore volume of the mercury removal agent is 0.5- 0.8ml/g; elemental sulfur is introduced to oxidize the deactivated cuprous sulfide into copper sulfide with mercury removal activity, thereby improving the utilization rate of copper sulfide and reducing the consumption of copper elements, and the addition of cerium oxide promotes The redox properties of sulfur, by adding additives, reduce the reaction activation energy of cuprous sulfide and elemental sulfur, and improve the effective utilization of copper. |
