Abstract
A process for transforming a gas oil cut into a dearomatized fuel with a high cetane number comprises at least one first, deep desulphurization and deep denitrogenation step in which the gas oil cut and hydrogen are passed over a catalyst comprising a mineral support, at least one group VIB metal or metal compound, at least one group VIII metal or metal compound, and phosphorous or at least one phosphorous compound, and at least one subsequent second step, dearomatization, in which the desulphurized and denitrogenated product from the first step is passed with hydrogen over a catalyst comprising a mineral support and at least one group VIII noble metal or noble metal compound.
