View the Complete Application at the US Patent & Trademark Office
The invention relates to catalysts and catalytic methods for selective oxidation of hydrogen sulfide (H.sub.2S) in a gas stream containing one or more oxidizable components other than H.sub.2S to generate sulfur dioxide (SO.sub.2), elemental sulfur (S) or both without substantial oxidation of the one or more oxidizable components other than H.sub.2S. The catalysts and methods herein are useful, for example, for the selective oxidation of H.sub.2S to SO.sub.2, sulfur or both in the presence of hydrocarbons, hydrocarbon oxygenate, sulfur-containing organic compounds, aromatic hydrocarbons, aliphatic hydrocarbons, carbon dioxide, hydrogen or carbon monoxide.
