Method of hydrodesulfuration of cuts containing sulphur compounds and olefins in the presence of a supported catalyst comprising elements from groups VIII and 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.
