Abstract
Using γ-Al2O3 as the main component and adding mass fraction 2%-5% copper oxide,2%-5% zinc oxide and 1%-2% molybdenum trioxide,the carrier with spherical particle size of (2-3) mm and specific surface area (200-250) m2·g-1 was prepared by disc granulation process,dryness and calcination.COS adsorbent was prepared by modifying the carrier with alkali metal hydroxide.The adsorption properties of COS adsorbent were investigated.The results indicated that the adsorption performance of COS adsorbent added with active oxide was good.The capacity of COS adsorption was up to 11.5 mg·g-1,and COS could be removed to 0.02 mg·m-3.
