Beschreibung
Zusammenfassung:	The invention relates to a method for converting petroleum feedstocks for the production of fuel oils having a low sulphur content, including the following successive steps: a step comprising the fixed-bed hydrodemetallation of the feedstock using, upstream, a system of switchable fixed-bed reactors; a step comprising the fixed-bed hydrocracking of the hydrodemetallised effluent in the presence of a hydrocracking catalyst; a separation step for obtaining a heavy fraction; and a step comprising the hydrodesulphurisation of the heavy fraction, in which hydrogen is reinjected.
