Claim:
A method for removing traces of hydrocarbons from gas flows: passing a flow of a nitric oxide-free gas containing traces of hydrocarbons in the range of 0.1 to 2,000 ppm over a catalyst while adding molecular oxygen and at a temperature in the range of 20 to 150° C., wherein said catalyst comprises a carrier material having a specific BET surface area of 1 to 1500 m 2 /g and at least one catalytic component on the surface of said carrier material, said at least one catalytic component is selected from the group consisting of: a) a share from 0.1 to 20% by weight of ruthenium relative to the total weight of the catalyst; and b) ruthenium and elements selected from the group consisting of bismuth, lead, molybdenum, manganese, tellurium, chromium, and combination thereof.
