Abstract: The influence of acidic properties of alumina of different modifications on the catalyst activity in the reaction of direct hydrogen sulfide oxidation has been studied. Acidic properties of α-Al₂O₃, γ-Al₂O₃, and γ-+χ-Al₂O₃ were studied using IR spectroscopy of adsorbed CO. A comparison of the catalytic activity and selectivity of alumina samples and IR spectroscopy data suggests that the H₂S adsorption proceeds predominantly on the LAS of intermediate strength.

Key words: H₂S oxidation hydrogen sulfide FTIR acidic sites activity
