ABSTRACT:
The present invention comprises a process for in situ fluorinating a catalyst by passing a gas containing hydrogen through a catalyst bed, injecting a gaseous organic fluorine compound into the gas and recycling the gas at such a low temperature and during such a long period that more than 50% of the fluorine compound is physically adsorbed on the catalyst, and then increasing the temperature of the bed so as to finish the in situ fluorination.
