ABSTRACT:
This application relates to a catalyst and a process using this catalyst to convert or destroy organic compounds including organohalogen compounds. A preferred catalyst contains as catalytic components titania, vanadium oxide, tungsten oxide, tin oxide and at least one noble metal selected from the group consisting of platinum, palladium and rhodium, characterized in that the vanadium oxide, tungsten oxide and noble metals are uniformly dispersed on the titania. The process of this invention comprises contacting the gas stream, which contains organohalogen compounds and other organic compounds, at a temperature of about 200.degree. to about 500.degree. C. with the catalyst described above in the presence of an oxidizing agent and water. The oxidizing agent can be oxygen or air.
