Process for regenerating used catalysts by means of hydrogen peroxide

The process has as an object the regeneration catalysts containing at least one contaminating metal of the vanadium, nickel and iron group. The operation is conducted as follows:

A heavy hydrocarbon charge containing sulfur, asphaltenes and/or resins is hydrotreated in the liquid phase at 250.degree.-500.degree. C. under a pressure of 20-350 bars in the presence of a catalyst previously obtained by reacting an organic compound of a transition metal with an organic aluminum compound, in a hydrocarbon free of asphaltene and resin. The transition metal organic compound is advantageously an iron, nickel, cobalt, molybdenum, tungsten or vanadium acetylacetonate or carboxylate.
