A completely metallic catalyst for the oxidation of mixtures in the gaseous phase which contain carbon monoxide, hydrocarbons and/or soot, has a surface doped with a metallic element and is subjected to a second thermal treatment in an oxygen-containing atmosphere.

Method of making a completely-metallic oxidation catalyst

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.

Catalyst for the oxidation of gaseous sulphur compounds

The invention relates to a catalytic hydrorefining of mixtures of hydrocarbons which contain hetero atoms such as nitrogen, sulphur, halogens and/or oxygen. The characterizing feature of the invention is that nickel or a nickel-molybdenum alloy containing more than 30% nickel, residue molybdenum, is thermally treated in an air atmosphere at temperatures of 400.degree. to 1200.degree. C. for a period of 0.25 to 10 hours, whereafter it is subjected to a hydrogen activation in the temperature range of 200.degree. to 600.degree. C.
