    摘要: The invention concerns a hydro treatment method in at least two stages, for a heavy hydrocarbon fraction containing asphaltenes, sulphur impurities and metallic impurities, wherein:a) in at least one first stage described as hydrodemetallization, the hydrocarbon charge and hydrogen are passed over a hydrodemetallization catalyst,b) in at least one subsequent stage described as hydrodesulphurization, the product of stage a) and hydrogen are passed over a hydrodesulphurization catalyst.The invention, in which the hydrodemetallization stage comprises one or more zones each containing hydrodemetallization catalyst operating in a fixed bed, is characterised in that this zone or these zones are preceded by two protective zones arranged in parallel, each containing a fixed bed of a hydrodemetallization catalyst, the two protective zones operating alternately.
