Abstract
A process for hydrotreating a hydrocarbon feed, comprising subjecting said feed to hydrotreating conditions in the presence of a catalyst comprising an essentially alumina-based extruded support, essentially constituted by a plurality of juxtaposed agglomerates, optionally at least one catalytic metal or a compound of a catalytic metal from group VIB (group 6 of the new periodic table notation) and/or optionally, at least one catalytic metal or a compound of a catalytic metal from group VIII (group 8, 9 and 10 of the new periodic table notation), in which the sum S of the group VIB and VIII metals, expressed as the oxides, is 0% to 50% by weight, and wherein each of these agglomerates is partly in the form of packs of flakes and partly in the form of needles, said needles being uniformly dispersed both about the packs of flakes and between the flakes, in which the alumina agglomerates are obtained by forming a starting alumina originating from rapid dehydration of hydrargillite and in which the amount of alumina from boehmite decomposition is 5% to 70% by weight.
