The present invention describes a process for the improvement of hydrocarbon mixtures that boil inside la-naphtha containing sulfur impurities, that is, a hydrodesulfurization process with contemporary isomerization of the skeleton and a reduced degree of hydrogenation of the olefins contained in the mixtures. of hydrocarbons, the entire process is carried out in a single stage. The process is carried out in the presence of a catalytic system comprising a metal of group VI B, a metal of group VIII, and a carrier of an acidic nature, consisting of a mesoporous silico-alumina. |
