    摘要: The invention relates to a catalyst usable in hydrotreatment processes, which comprises an alumina-based amorphous support, phosphorus, a C1-C4 dialkyl succinate, acetic acid and a hydro-dehydrogenizing function comprising at least one group VIII element and at least one group VIB element, preferably made up of cobalt and molybdenum, a catalyst whose Raman spectrum comprises the most intense bands characteristic of the Keggin heteropolyanions (974 and/or 990 cm−1), C1-C4 dialkyl succinate and acetic acid (896 cm−1). Preferably, the dialkyl succinate concerned is dimethyl succinate and its main band is at 853 cm−1.The invention also relates to the method of preparing said catalyst, wherein a catalytic precursor comprising the group VIB and group VIII elements, in particular the molybdenum-cobalt pair, and phosphorus, introduced by impregnation, then dried at a temperature below 180° C., is impregnated by the C1-C4 dialkyl succinate, the acetic acid and the phosphorus compound, if the latter has not been entirely introduced beforehand, then, after maturation, dried at a temperature below 180° C. prior to being optionally sulfurized.The invention also relates to the use of this catalyst in any hydrotreatment process.
