CATALYSEUR D'HYDROTRAITEMENT, SON PROCEDE DE PREPARATION ET SON UTILISATION DANS UN PROCEDE DE PURIFICATION D'HYDROCARBURES.

摘要

A hydrotreating catalyst comprising Group VIII and VI metal oxides on a refractory oxide support is modified with a benzothiophene sulfone or sulfoxide. Independent claims are also included for the following: (1) the production (P1) of the above modified catalyst by depositing or forming the sulfone or sulfoxide on the surface of the catalyst; and (2) a process (P2) for reducing the sulfur content of a sulfur-, nitrogen- and/or aromatics-containing hydrocarbon feed to less than 10 ppm by hydrotreating the feed with the modified catalyst in sulfurized form and oxidatively desulfurizing the hydrotreated feed.
