Catalytic hydrolysis of carbonyl sulfide in blast furnace gas over Sm-Ce-O_x@ZrO₂ catalyst.

ABSTRACT: Carbonyl sulfur (COS) is a prominent organic sulfur pollutant commonly found in the by-product gas generated by the steel industry. A series of Sm-doped CeO_x@ZrO₂ catalysts were prepared for the hydrolysis catalytic removal of COS. The results showed that the addition of Sm resulted in the most significant enhancement of hydrolysis catalytic activity. The 3% Sm₂O₃-Ce-O_x@ZrO₂ catalyst exhibited the highest activity, achieving a hydrolysis catalytic efficiency of 100% and H₂S selectivity of 100% within the temperature range of 90-180 °C. The inclusion of Sm had the effect of reducing the acidity of the catalyst while increasing weak basic sites, which facilitated the adsorption and activation of COS mo
