The invention discloses a kind of mercury removal agent and preparation method thereof, described mercury removal agent comprises the modifier of the carrier of 40-90wt%, the active component of 1-40wt% and 0-30wt%; Described modifier is halogen or halide; Described active component is the mixture of the oxidisability metal oxide of at least two kinds; Described preparation method is: carrier is placed in the oxidizing metal salts solution that one or more are solvable, impregnation drying, calcining, then be placed in one or more the soluble metal salt solution except above-mentioned soluble metallic salt, dipping, dry, calcining.Mercury removal agent of the present invention does not need sulfuration, it is using oxidisability metal oxide as active component, halogen or halide are as modifier, there is the mercury being greater than 10wt% hold, and demercuration efficiency reaches the beneficial effect of more than 99.9%, also can be widely used in the removing process of mercury metal in mercurous source of the gas in flue gas, synthesis gas and natural gas and liquid. |
