摘要: A process is described for enhancing the fuel properties of hydrotreated, and possibly dearomatized, hydrocarbon mixtures, which comprises putting said mixtures in contact, presence hydrogen, with a new catalytic system comprising: (1) zone (I) containing metallic component T1 selected from Pt, Pd thereof, carrier S1 from: (a) dealuminated large-pore zeolites, (b) zeolites having crystalline lattice based on silica alumina, exchanged one or more metals Me alkaline metals, alkaline-earth lanthanoids x moles hydrogen ions per mole aluminium wherein varies 0.04 to 0.4, (c) amorphous silico-aluminas, phosphorous; (2) (II) T2 Ir, mixture Ir Pt Rh, S2 borated silica, ceria, titania, zirconia.
