Abstract
Catalyst body for breaking down halogenated hydrocarbons, in particular dioxins and/or furans, having an active material which comprises titanium dioxide, carbon and at least one active component which is selected from the group consisting of oxides and mixed oxides of the transition metals, of the lanthanides, of the actinides, of the alkali metals and alkaline-earth metals, of aluminum, of tin and of silicon. In an off-gas flowing through the catalyst body, the levels of hydrocarbons contained therein are effectively reduced in part by adsorption and in part by oxidation, in particular at temperatures below 250° C.
