Abstract
The claimed invention relates to a catalytic process for the selective oxidation of sulfur-containing compounds, in particular hydrogen sulfide, to form elemental sulfur. The catalyst includes a carrier of which the surface exposed to the gaseous phase does not exhibit alkaline properties under the reaction conditions, and a catalytically active material applied thereto or formed thereon. The specific surface area of the catalyst is less than 20 m.sup.2 /g catalyst, with less than 10% of the total pore volume having a pore radius between 5 and 500 .ANG.. A process for preparing the catalyst is also disclosed.
