Abstract
The present invention relates to a catalytic composition which comprises an ERS-10 zeolite, a metal of group VIII, a metal of group VI and optionally one or more oxides as carrier. According to a preferred aspect, the catalytic composition also contains a metal of group II B and/or III A. The catalytic system of the present invention can be used in the upgrading of hydrocarbon mixtures having boiling ranges within the range of C.sub.4 to 250.degree. C., preferably mixtures of hydrocarbons which boil within the naphtha range, containing impurities of sulfur, i.e. in hydrodesulfuration with the contemporaneous skeleton isomerization of olefins contained in these hydrocarbons, the whole process being carried out in a single step.
