Abstract
A process is described for improving the quality as a fuel of hydrotreated hydrocarbon blends by reaction with hydrogen in the presence of a bifunctional catalytic system comprising one or more metals selected from Pt, Pd, Ir, Ru, Rh and Re, and a silico-aluminate of an acidic nature, selected from a micro-mesoporous silico-alumina and a zeolite belonging to the MTW family. The process of the invention produces an increase in the cetane index and a decrease in the density and T95.
