Abstract

Activity and selectivity in hydrogen sulfide oxidation by oxygen on a Fe<sub>2</sub>O<sub>3</sub>/α-Al<sub>2</sub>O<sub>3</sub> catalyst was studied at 200°C and atmospheric pressure. Reaction products were sulfur and sulfur dioxide. Two factors influencing catalytic activity were studied: support porous structure and the type of Fe<sub>2</sub>O<sub>3</sub> precursor. The porous structure influenced substantially catalytic activity; mesopores were more active than macropores. The catalysts prepared from Fe(NO<sub>3</sub>)<sub>3</sub> and iron(III) acetylacetonate exhibited comparable activity, the lower activity was found for the catalyst prepared from Fe<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>. The selectivity to sulfur formation was higher on catalysts containing greater amount of macropores and the value of it changed in the interval 0-85% depending on the type of catalyst.
