Abstract

The invention relates to a process for catalytic treatment of heavy hydrocarbons, in a fixed or moving bed, over a catalyst containing an alumina carrier and at least one catalytic metal or compound of metal from groups VB, VI B and VIII of the periodic classification of elements, characterized by the direct injection into the charge, continuously or periodically, of at least one metal compound selected from the group consisting of halides, oxyhalides, oxides, polyacids and polyacid salts of metals from groups VI B, VII B and VIII, before introducing the charge into the hydrotreatment zone.
