PROCESS FOR THE PRODUCTION OF CHLORINE USING A CERIUM OXIDE CATALYST IN AN ADIABATIC REACTION CASCADE

摘要

A process for the production of chlorine by thermo-catalytic gas phase oxidation of hydrogen chloride and oxygen is described, the process comprising at least (1) a cerium oxide catalyst and (2) an adiabatic reaction cascade, containing at least two adiabatic stages connected in series with intermediate cooling, wherein the molar O2/HC1-ratio is equal or above 0,75 in any part of the cerium oxide catalyst beds.
