ИК спектроскопическое исследование кислотности поверхности оксидов алюминия и их активность в реакции окисления h 2S

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 a-Al2O3, g-Al2O3, and g-+c-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.
