CATALYST FOR THE SELECTIVE oxidation of sulfur containing compounds, in particular hydrogen sulfide to elemental sulfur; Process for the preparation of the catalyst and process for the selective oxidation of sulfur-containing compounds, in particular hydrogen sulfide to elemental sulfur.

摘要

The invention relates to a catalyst for the selective oxidation of sulfur-containing compounds, in particular hydrogen sulfide, to form elemental sulfur, comprising 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. According to the invention the catalyst is characterized in that the specific surface area of the catalyst is less than 20m2/g catalyst, with less than 10% of the total pore volume having a pore radius between 5 and 500 A. The invention also relates to a process for preparing the catalyst, and to processes using it.
