A process for the re-generation of a used catalyst from a hydrocarbon treatment process comprises at least one precious metal amongst Ag, Au, Ru, Rh, Pd, Os, Ir and Pt, and at least one porous support. The process is effected in 2 stages: (1) Combustion of the coke present on the catalyst, at 300-68...
