ABSTRACT:
A novel cerous chloride-chromium oxide catalyst useful for oxidizing hydrogen chloride to chlorine. The catalyst is prepared by the reaction of chromium trioxide and cerous chloride with ethanol and calcining the reaction product. The catalyst is also prepared by the reaction of chromium trioxide with ethanol, then calcination and impregnation of the resultant chromic oxide with aqueous solution of cerous chloride. The obtained catalyst exhibits high activity at low reaction temperature.
