Abstract

The invention concerns a catalyst containing a support comprising at least one binder and at least one zeolite having at least one series of channels the opening of which is defined by a ring containing 12 oxygen atoms, said catalyst comprising phosphorus, at least one C1-C4 dialkyl succinate, acetic acid and a hydrodehydrogenating function comprising at least one element from group VI B and at least one element from group VIII, the Raman spectrum of the catalyst comprising bands at 990 and/or 974 cm-1, characteristic of at least one Keggin heteropolyanion, the characteristic bands of said succinate and the characteristic principal band of acetic acid at 896 cm-1. The invention also concerns the process for preparing the catalyst and its use in hydroconversion.
