A heavy hydrocarbon charge containing sulfur, asphaltenes and/or resins is hydrotreated in the liquid phase at 250°-500°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 h

A heavy hydrocarbon charge containing sulfur, asphaltenes and/or resins is hydrotreated in the liquid phase at 250°-500°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.

A process for hydrotreating a heavy hydrocarbon charge containing sulfur and asphaltenes, in the liquid phase, comprising contacting said charge with hydrogen, at a temperature of 250°-500°C. and a pressure of 20-350 bars, in the presence of a preformed catalyst prepared by reacting at least one tra

A process for hydrotreating a heavy hydrocarbon charge containing sulfur and asphaltenes, in the liquid phase, comprising contacting said charge with hydrogen, at a temperature of 250°-500°C. and a pressure of 20-350 bars, in the presence of a preformed catalyst prepared by reacting at least one transition metal organic compound with at least one organic aluminum compound, in a hydrocarbon solvent which is substantially free of asphaltenes, said transition metal being titanium, zirconium, vanadium, chromium, molybdenum, tungsten, manganese, rhenium, iron, ruthenium, cobalt, nickel, copper, zinc or tin.
