Abstract:
A subject-matter of the present invention is a process for the regeneration of a catalyst comprising at least one metal from Group VIII and at least one metal from Group VIB which are deposited on a refractory oxide support, comprising: at least one first step of heat treatment of the catalyst in the presence of oxygen and at a temperature ranging from 350° C. to 550° C.; at least one second step of deposition, at the surface of the catalyst, of one or more additive(s) of formula (I):
