PRECISION OF DISCLOSURE: The invention relates to a hydrotreatment process. a heavy load of hydrocarbons, containing sulfur and asphaltenes and / or resins, in the liquid phase, in which puts said charge and hydrogen in contact with a catalyst, at a temperature of 250 to 500 ° C and under a pressure from 20 to 350 bars. The process is characterized by what we use a catalyst prepared by reaction prior, in a hydrocarbon, of at least one organic compound transition metal, with at least one organic compound aluminum, in the absence of asphaltene and resin, the metal of the organic compound being chosen from the group consisting by titanium, zirconium, vanadium, chromium, molybdenum, tungsten, manganese, rhenium, iron, ruthenium, cobalt, nickel, copper, zinc and tin. The catalytic treatment of the process of the invention allows the elimination of pollutants such as sulfur and compounds harmful to the refining stages such as nitrogen, oxygen, metals, especially nickel and vanadium and asphaltenes, so that the next step hydrocracking or catalytic cracking of these residues heavy in light value products such as gasoline and diesel, is possible. |
