Process for the production of a catalytically active mass, catalyst with a catalytically active mass produced in this way and use of the catalyst for the decomposition of dioxins and / or furans

摘要

In order to produce a catalytically active substance, titanium dioxide is processed together with an oxide or with a dissolved compound of tungsten and/or vanadium to form a moldable material. The moldable material is dried to form a shaped body and the shaped body is calcinated. According to the invention, the shaped body is, after calcination, additionally impregnated with a dissolved compound of titanium and vanadium and is dried once more. A catalytically active substance of this type exhibits a high degree of catalytic activity for degrading dioxins and/or furans also at temperatures lower than 250 DEG C. The catalytically active substance is especially suited for producing dioxin and/or furan catalysts.
