Abstract:
Process for hydrotreating a heavy hydrocarbon fraction using a system of switchable fixed bed guard zones each containing at least one catalyst bed including at least one step during which the flow of feed supplied to the first guard zone brought into contact with the feed is partly displaced to the next guard zone downstream, preferably progressively.
