ABSTRACT OF THE DISCLOSURE A catalyst for the hydrotreatment of hydrocarbons com- prises refractory oxide-mineral carrier; a halogen element, pre- sent in combined form; and, in free or combined form, (a) from 0.02 to 2%, based on the total weight of the catalyst, of at least one metal M1 from the platinum group, and (b) from 0.02 to 2%, based on the total catalyst weight, of tin, said catalyst contain- ing, in combined form, at least one metal M2 selected from groups Ia and IIa of the Periodic Table of the Elements is such an amount that the ratio Image of the number of atoms of the metal M2 to the number of atoms of the metal M1 is such that Image . Specifically, said metal from groups Ia and IIa may be sodium, lithium, potassium, calcium or barium. The catalyst provides for improved yields of effluents having a very good octane number and lend themselves to the isomerization of alkylaromatic hydrocarbons.
