Preparation of chlorine, by oxidation, from chlorine-containing metal compounds comprises reacting the metal compounds with oxygen or gas containing oxygen and simultaneously exposing to the effect of non-thermal plasma to form chlorine

Preparation of chlorine, by oxidation, from chlorine-containing metal compounds, comprises (a) reacting the chlorine-containing metal compounds with oxygen or gas containing oxygen and simultaneously exposing to the effect of non-thermal plasma to form chlorine, metal oxide and/or optional metal oxychloride. An independent claim is included for a barrier reactor comprising one or more current-limiting dielectrical barriers, preferably for oxidation of chlorine-containing metal compounds with oxygen-containing gas, where the chlorine-containing metal compounds are provided as solid bed in the discharge space of the barrier reactor. Es wird ein Verfahren zur Herstellung von Chlor durch katalytische Oxidation von gasförmigem Chlorwasserstoff unter der Einwirkung eines nichtthermischen Plasmas beschrieben.
