Carbonyl Sulfide Hydrolysis over Alkali Promoted CeO2-Al2O3 Mixed Oxide Catalysts for Wide Temperature Desulfurization Applications

Alkali promoted CeO₂-Al₂O₃ mixed oxides have been studied for their application in the COS hydrolysis reaction at mild conditions. Although, addition of Ceria to Alumina support didn’t provide significant increase in COS conversion rates compared to blank Al₂O₃, the hydrolysis activity was maintained in presence of high COS partial pressures.
