Abstract
A description is given of a process for hydrotreatment of at least one hydrocarbon feedstock having a weighted average temperature (WAT) of more than 380° C. using at least one catalyst containing at least one metal from Group VIB and/or at least one metal from Group VIII of the periodic table and a support containing an amorphous mesoporous alumina having a connectivity (Z) of more than 2.7, said hydrotreatment process operating at a temperature of between 250° C. and 430° C., at a total pressure of between 4 MPa and 20 MPa with a ratio of volume of hydrogen to volume of hydrocarbon feedstock of between 200 and 2 000 liters per liter and at an Hourly Volume Velocity (HVV) defined by the ratio of the volume flow of liquid hydrocarbon feedstock to the volume of catalyst fed into the reactor of between 0.5 and 5 h−1.
