ABSTRACT:
According to the specified process chromium oxyfluoride catalysts which have largely lost their activity are regenerated. The catalysts are mixed with magnesium oxide or magnesium hydroxide in the presence of water and converted into a paste. If necessary the mixture must be concentrated by evaporation until it exhibits the consistency of a paste. Finally the paste is dried. The paste is best converted into molded bodies such as, for example, granules before drying.
