    摘要: A treating apparatus for decomposing organohalogen compounds such as chlorofluorocarbons (CFC's), trichloroethylene, methylbromide, halon, and the like, effectively, with a high activity of catalyst, is provided. The apparatus includes a reactor in which organohalogen compounds are decomposed by contact at a temperature in a range of 200.degree..about.500.degree. C. with a catalyst which comprises titania and tungsten oxide by an atomic ratio of Ti and W in a range from 20 mol % to 95 mol % Ti and from 5 mol % to 80 mol % W, with at least the surface of the titania being covered with a porous layer of the tungsten oxide. In accordance with the present invention, organic compounds containing any of fluorine, chlorine and bromine will be decomposed with a high efficiency, and the activity of the catalyst can be maintained for a long time.
