Abstract

γ-Al₂O₃ modified with different impregnants has been studied for COS removal efficiency under micro-oxygen conditions. γ-Al₂O3 modified with 5%KOH is found to have markedly enhanced its adsorption purification ability. In the adsorption purification process, the reaction temperature and oxygen concentration of the gas are determined to be two crucial factors. After heating regeneration, the adsorption efficiency of spent sorbent (K/γ-Al₂O₃-R1 and R2) were still effective and stable. And it will be of use after heating regeneration. According to the current study results, the γ-Al₂O₃ impregnated with 5%KOH promises a good candidate for COS adsorbent.
