The invention relates to a catalyst containing a support including at least one binder and at least one zeolite and having at least one series of channels, the opening of which is defined by a ring containing 12 oxygen atoms, said catalyst including phosphorus, at least one C1-C4 dialkyl succinate, acetic acid, and a hydro-dehydrogenating function that contains at least one Group VIB element and at least one Group VIII element. The Raman spectrum of said catalyst includes 990 and/or 974 cm-1 bands characteristic of at least one Keggin heteropolyanion, bands characteristic of said succinate, and the main 896 cm-1 band characteristic of acetic acid. The invention also relates to the method for preparing the catalyst and to the use of said catalyst in hydroconversion. L'invention concerne un catalyseur contenant un support comprenant au moins un liant et au moins une zéolite ayant au moins une série de canaux dont l'ouverture est définie par un anneau contenant 12 atomes d'oxygène, ledit catalyseur comprenant du phosphore, au moins un succinate de dialkyle C1-C4, de l'acide acétique et une fonction hydro- déshydrogénante comprenant au moins un élément du groupe VIB et au moins un élément du groupe VIII, catalyseur dont le spectre Raman comprend les bandes à 990 et/ou 974 cm'1 caractéristiques d'au moins un hétéropolyanion de Keggin, les bandes caractéristiques dudit succinate et la bande principale à 896 cm'1 caractéristique de l'acide acétique. L'invention concerne également le procédé de préparation du catalyseur et son utilisation en hydroconversion.
