Abstract (en)

[origin: WO2005103207A1] A process is described for the upgrading of distil­ lates having a boiling point ranging from 100 to 450°C, which comprises the opening of the ring of the naphthene compounds contained in these distillates to obtain paraf­finic compounds, rich in branched paraffins, having for the most part the same number of carbon atoms as the starting naphthene. The process is carried out in the presence of a bifunctional catalytic system comprising one or more metals selected from Pt, Pd, Ir, Ru, Rh and Re, and a silico­aluminate of an acidic nature, selected from a micro­mesoporous silico-alumina and a zeolite belonging to the MTW group.
