Abstract

A particularly thermally stable and acid resistant catalyst for reacting organic compounds present in a gas mixture, e.g. hydrocarbons, halogenated hydrocarbons, alcohols and solvents, includes titanium oxide, vanadium oxide and at least one further catalytically active component. The titanium oxide is predominantly present as titanium dioxide TiO.sub.2 of the rutile type having a BET surface area of greater than 40 m.sup.2 /g. The catalyst can be used for purifying combustion waste gases of all types and for purifying industrial waste air.
