PROCESS FOR THE PRODUCTION OF CHLORINE USING A CERIUM OXIDE CATALYST IN AN ISOTHERMIC REACTOR

摘要

A process for the production of chlorine by thermo-catalytic gas phase oxidation of hydrogen chloride gas with oxygen, in the presence of a catalyst, and separation of the chlorine from the reaction products comprising chlorine, hydrogen chloride, oxygen and water, characterized in that a) a cerium oxide is used as catalytically active component in the catalyst and b) the reaction gases are converted at the cerium oxide catalyst in one or more isothermic reaction zones, preferably in one or more tube bundle reactors, wherein the molar O2/HCl-ratio is equal or above 0.75 in any part of the cerium oxide containing reaction zones.
