PROCEDE D'HYDRODESULFURATION DE COUPES CONTENANT DES COMPOSES SOUFRES ET DES OLEFINES EN PRESENCE D'UN CATALYSEUR SUPPORTE COMPRENANT DES ELEMENTS DES GROUPES VIII ET VIB

摘要

Catalyst comprises a support, an element of group VIII, an element of group VIB and phosphorus, where: the element-VI is present in an oxide form and has a density of 2x10 ->4 to 18x10 ->4 g of per m 2> of the support; the phosphorus:group VIB element molar ratio is >=0.25; and the elements VIB content is 1-20 wt.%. An independent claim is included for a hydrodesulfuration process of gasoline fraction comprising hydrodesulfuration of the fraction in the presence of the catalyst.
