DECOMPOSITION BY CATALYST OF ORGANIC HALOGENATED COMPOUND

PROBLEM TO BE SOLVED: To convert an organic halogenated compound into carbon dioxide and halogenoacid by bringing a gas flow into contact with a catalyst containing titania in the presence of water of effective volume. SOLUTION: This catalyst contains titania. A preferable catalyst contains also tungsten oxide. If the oxidization of hydrocarbon is desired, a preferable catalyst contains titania and vanadium oxide, and a particularly preferable catalyst contains at least one kind of precious metal selected from a group composed of tungsten oxide, platinum, palladium and rhodium. Also it is preferable to add tin oxide as a stabilizer. Titania is an active catalyst, and not a simple carrier. A titania component has desirably the surface area of approximately 10 - approximately 150 m /g. Any kinds of structure and dimension to be exposed to gas dispersed on the titania and other catalyst components dispersed on the titania can be used, e.g. in the form of fine particles.
