  • Publication number: 20220184578
    Abstract: Disclosed is a method for producing a granular adsorbent for carbon monoxide or carbon disulfide separation. According to the method, incipient wet impregnation and sonication are performed simultaneously and the amount of an impregnation solution and the average particle diameter of a particulate adsorbent are adjusted to optimal ranges to produce a granular adsorbent that is evenly and uniformly impregnated with metal ions, achieving significantly improved carbon monoxide and carbon disulfide adsorption capacities. Also disclosed is a granular adsorbent for carbon monoxide or carbon disulfide separation produced by the method. The granular adsorbent has highly stable physical properties, does not cause problems such as pressure drop or line contamination during use, and is simple to produce because the use of a solvent such as a strong acid or base is not required during production. Also disclosed is a separator including the granular adsorbent.
