HYDRO TREATMENT CATALYST, UNDERSTANDING A SUPPORT OBTAINED FROM AN ALUMINUM GEL AND METHOD OF PREPARING THIS CATALYST. The present invention relates to a hydrotreating catalyst, comprising a support, at least one metal chosen from the group VIB and at least one metal chosen from group VIII of the periodic table, the metal content of the group VIB expressed in oxides being comprised between 6 and 25% by weight in relation to the total weight of the catalyst, the metal content of group VIII expressed in oxides being between 0.5 and 7% by weight, in relation to the total weight of the catalyst, the support comprising at least 90 % by weight of alumina, in which this alumina is obtained from a boiled and extruded bohemian gel, and in which the specific surface of this catalyst is between 60 and 250 m2 / g. |
