Abstract
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.
