ABSTRACT:
The present invention concerns a regeneration process for a catalyst containing at least one metallic element selected from the group formed by platinum, palladium, ruthenium, rhodium, osmium, iridium and nickel, preferably platinum, on a refractory oxide based support, which has been deactivated by coke deposition. The regeneration process is characterised in that said regeneration consists of treatment with a gas containing at least chlorine and molecular oxygen, at a temperature between 20.degree. C. and 800.degree. C. and a total gas flow rate, expressed in litres of gas per hour and per gram of catalyst, of between 0.05 and 20. The process at least restores the initial catalytic properties of the catalyst.
