Abstract
The invention relates to a process for hydrocracking hydrocarbon feedstocks having 200 ppm by weight to 2% by weight of asphaltenes and/or more than 10 ppm by weight of metals, comprising a hydrodemetallation treatment in at least 2 switchable reaction zones, containing hydrodemetallation catalyst and optionally hydrodenitrification catalyst, then a hydrorefining treatment to lower the organic nitrogen content, followed by a fixed-bed hydrocracking treatment and a distillation step.
