Abstract

The invention concerns a process for the oxidation of organic compounds contained in a gas stream and comprises the step of introducing the gas stream containing the organic compounds together with sufficient oxygen to effect the desired amount of oxidation into an oxidation reactor containing an oxidation catalyst and maintaining the temperature of said gas stream at a temperature sufficient to effect oxidation, characterised in that the oxidation catalyst contains at least 0.01% by weight of ruthenium, cobalt or manganese.
