Abstract

To recover a copper chloride/potassium chloride catalyst, as used in HCl oxidations to form Cl2, from a fluidised bed in a form suitable for re-fluidisation, the HCl feed is stopped but the temp. is maintained at 360 degrees C or higher for at least 6 hrs. in a gas contg. oxygen but no HCl or Cl2. The catalysts are esp. those contg. rare earth chlorides e.g., didymium chloride.
