Method for regenerating a zeolite-based hydrocracking catalyst, and use thereof in a hydrocracking process

Abstract

The present invention relates to a process for the regeneration of an at least partially spent catalyst resulting from a hydrocracking process, said at least partially spent catalyst resulting from a fresh catalyst comprising at least one metal from group VIII, at least one metal from group VIb and a support comprising at least one zeolite, said process comprising at least one regeneration stage in which the at least partially spent catalyst is subjected to a heat and/or hydrothermal treatment in the presence of an oxygen-containing gas at a temperature of between 350° C. and 460° C. so as to obtain a regenerated catalyst, said process not comprising a subsequent rejuvenation stage of bringing said regenerated catalyst into contact with at least one organic or inorganic and acidic or basic compound.
