Abstract
The invention relates to an all-metal catalyst for the oxidation of gaseous sulphur compounds, more particularly hydrogen sulphide, in an oxygen-containing atmosphere, said catalyst consisting of a metal alloy of 5 to 70% by weight nickel and 30 to 95% by weight copper as residue thermally treated at temperatures of 400.degree. to 1000.degree. C. in an oxygen-containing atmosphere for 0.25 to 5 hours.
Claims6
A method for oxidizing gaseous hydrogen sulphide, carbon monoxide sulphide, or combinations thereof, comprising, in an oxygen-containing atmosphere, bringing said compounds into contact with a metal alloy catalyst initially consisting essentially of 5 to 70% by weight nickel and 30-95% by weight copper as residue, said metal alloy catalyst having been thermally treated at a temperature of 400.degree.-1,000.degree. C. in an oxygen-containing atmosphere for 0.25 to 5 hours.
A method for oxidizing gaseous hydrogen sulphide, carbon monoxide sulphide, or combinations thereof, comprising, in an oxygen-containing atmosphere, bringing said compounds into contact with a metal alloy catalyst initially consisting essentially of 5 to 70% by weight nickel, not more than a total 5% by weight of iron, manganese, zinc, chromium, aluminum, titanium, carbon, phosphorous, sulphur, and combinations thereof, and 30-95% by weight copper as residue, said metal alloy catalyst having been thermally treated at a temperature of 400.degree.-1,000.degree. C. in an oxygen-containing atmosphere for 0.25 to 5 hours.
