Abstract: Process for destroying organic halogen compounds, which are contained in dust-containing gases which have a carbon content of less than 0.6% by weight, by oxidative degradation with the aid of fixed catalysts suitable for this purpose, characterised in that a) the dust is separated off at 250 to 500 DEG C from the gases and the dust-free gas together with oxygen or an oxygen-containing gas is passed over the catalyst, or b) the dust is separated off below 250 DEG C, the organic halogen compounds are desorbed from the dust in an oxygen-containing gas stream at 250 to 500 DEG C and the gas stream is passed over the catalyst, or c) the dust-containing gas is passed over the catalyst in the presence of oxygen at 250 to 500 DEG C and the dust is then separated off.

Abstract: Catalyst containing metallic oxides, which in addition to oxides of titanium and/or zirconium, oxides of vanadium and/or niobium and oxides of molybdenum, tungsten and/or chromium, also contains sulphates of the alkaline earth metals, and which is used in a process for the oxidative breakdown of organic compounds in the waste gases from incinerator plants.

Abstract: In the removal of NOx from waste gases by selection redn. with NH3 in the presence of zeolites as catalysts, Fe silicate zeolites (I) are used as catalysts. (I) is of the pentasil type and pref. is in the H form. (I) pref. is doped with gp. IB, IIB, IVB, VB, VIB, VIIB and/or VIII transition metal(s) and/or rare earth metal(s).
