VERFAHREN ZUR RUECKGEWINNUNG VON CHLOR AUS CHLORWASSERSTOFF MITTELS EINES TRANSPORTKATALYSATORS, SOWIE ANLAGE ZUR DURCHFUEHRUNG DES VERFAHRENS

摘要

The method comprises two stages: (1) passing a gaseous current of hydrogen chloride across a fluidized bed of copper oxides and sodium chloride deposited onto a suitable support, the reaction of the hydrogen chloride with the oxides to form a complex chloride taking place in a reactor (11); and (2) passing the chlorinated transport catalyst over a fluidized bed of transport catalyst which contains copper chloride and sodium, injecting a mixture of oxygen and nitrogen, carrying out the oxidizing reaction in a reactor (21) and liberating chlorine from the catalytic mass while the copper chloride is converted into copper oxide, extracting a continuous flow of transport catalyst which returns to the first stage. An absorption/ separation system (47) using carbon tetrachloride recovers the chlorine give off in the reactor (21). <IMAGE>
