The invention belongs to the technical field of desulfurization, and particularly relates to an efficient desulfurization material and a preparation method thereof. The high-efficiency desulfurizationmaterial is prepared from industrial carbon-based
solid waste, an
adhesive, a pore-forming agent and an activating agent. The method comprises the following steps: (1) adjusting the industrial carbon-based
solid waste to be alkaline, dehydrating, adding the
adhesive, the pore-forming agent and the activating agent, uniformly mixing, adding water, reacting, and granulating and forming after the reaction is finished; and (2)
drying the molded material, and carrying out secondary
carbonization and
water vapor reactivation treatment to obtain the finished product of the carbon-based composite adsorption material. According to the method, the industrial carbon-based
solid waste is recycled; carrying out modification and pore
size adjustment; after being impregnated with the
active components,the desulfurization material is more suitable for gas-phase removal of
hydrogen sulfide in the industries of
coal chemical industry,
petrochemical industry and the like, the
sulfur capacity of the desulfurization material can reach 35% or above, and meanwhile, through reasonable pore size distribution, the converted elemental
sulfur is deposited in a semi-firm state, is easier to desorb and regenerate, has high
working capacity, can be recycled, and is energy-saving and environment-friendly.
