ABSTRACT:
This invention relates to a method of hydrotreating hydrocarbon-based charges by using a catalyst that comprises V.sub.2 S.sub.3 prepared in situ in the reaction zone or V.sub.2 S.sub.3 prepared outside this zone but treated in this zone by a sulphurating agent. The hydrotreating method according to the invention can be used to treat hydrocarbon-based charges such as gasoline, gasoil, refinery residues and heavy crude oils, thus allowing the elimination of impurities such as nitrogen, sulphur and metals. The method can also be used to hydrogenize the olefins and the aromatics and possibly lead to rupture of the carbon-carbon bonds.
