A process for dearomatization of a petroleum cut produces a dearomatized hydrocarbon-containing fluid with a sulphur content less than or equal to 5 ppm and a content of aromatic compounds less than or equal to 300 ppm, the hydrocarbon-containing fluid has a boiling point between 100 and 400&#xb0; C. according to the standard ASTM D-86 and a distillation range defined by the difference between the Initial Boiling Point (IBP) and the Final Boiling Point (FBP) determined by the standard ASTM D-86 not exceeding 80&#xb0; C. The process includes at least one dearomatization cycle utilizing a mixture of the petroleum cut with one or more inert and light diluents having a distillation range not exceeding 80&#xb0; C.

Process for the dearomatization of petroleum cuts

The invention concerns a catalyst containing a support comprising at least one binder and at least one zeolite having at least one series of channels the opening of which is defined by a ring containing 12 oxygen atoms, said catalyst comprising phosphorus, at least one C1-C4 dialkyl succinate, acetic acid and a hydrodehydrogenating function comprising at least one element from group VI B and at least one element from group VIII, the Raman spectrum of the catalyst comprising bands at 990 and/or 974 cm-1, characteristic of at least one Keggin heteropolyanion, the characteristic bands of said succinate and the characteristic principal band of acetic acid at 896 cm-1. The invention also concerns the process for preparing the catalyst and its use in hydroconversion.
