Abstract (en)
[origin: WO03044132A1] The invention concerns a method for hydrotreating of a hydrocarbon feedstock, comprising at least two steps with intermediate stripping of the effluent of the first step with pressurized hydrogen substantially free of unwanted impurities for the second step catalyst, to eliminate in particular part of the H2S formed, each step being performed with a hydrogen recycling loop particular to said step.
