Abstract

The invention discloses a preparation method of a compound adsorbent mixture, an adsorbent particle and a compound adsorbent for purifying VOCs and belongs to the field of atmospheric VOCs treatment. The method comprises the steps of adding a mixture A and a mixture B to a mixer, adding water to mix and mixing evenly; and adding an additive to the mixer and mixing evenly to prepare the adsorbent mixture, wherein the mixture A comprises activated aluminum oxide, activated carbon and iron ore powder; and the mixture B comprises a pellet sieve residue, a biomass material, magnesium laterite-nickel ore and kaolin. The adsorbent has relatively high porosity and specific surface area; and when the VOCs are in contact with the adsorbent, the adsorbent can be in full contact with the VOCs, and the adsorption efficiency of the adsorbent is improved, thereby achieving high-efficiency and low-cost emission reduction of the VOCs.
