<p>A process is described for enhancing the fuel quality of hydrotreated hydrocarbon blends, possibly dearomatized, through reaction with hydrogen, in the presence of a new catalytic composition comprising one or more metals selected from Pt, Pd, Ir and Rh, and a zeolite of the FAU type, containing one or more cations of metals Me selected from alkali metals, alkaline earth metals, and lanthanoids, and containing from 0.04 to 0.4 moles of hydrogen ions per mole of aluminium present in the crystalline lattice of the zeolite. The process of the invention leads to an increase in the cetane number and a decrease in the density and T 95 , with a high selectivity in the gas oil cut.</p> |
