Abstract
A catalyst usable in hydrotreatment processes: an alumina-based amorphous support, phosphorus, a C1-C4 dialkyl succinate, acetic acid and a hydro-dehydrogenizing function of 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.
