CATALYTIC COMPOSITION FOR THE UPGRADING OF HYDROCARBONS HAVING BOILING TEMPERATURES WITHIN THE NAPHTHA RANGE

摘要

A process for preparing a catalytic composition The present invention relates to a process for preparing a catalytic composition comprising an ERS-10 zeolite, a metal of group VIII, a metal of group VI 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 250°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.
