Abstract
The present invention describes a process for hydrocracking at least one hydrocarbon feed in which at least 50% by weight of the compounds have an initial boiling point of more than 300° C. and a final boiling point of less than 540° C. using at least one catalyst comprising at least one metal from group VIB and/or at least one metal from group VIII of the periodic classification of the elements and a support comprising at least one zeolite containing at least one series of channels the opening of which is defined by a ring containing 12 oxygen atoms (12MR), and at least one binder, said support being prepared from a highly dispersible alumina gel, said hydrocracking process being operated at a temperature in the range 200° C. to 480° C., at a total pressure in the range 1 MPa to 25 MPa, with a ratio of the volume of hydrogen to the volume of hydrocarbon feed in the range 80 to 5000 litres per litre and with an hourly space velocity (HSV), defined as the ratio of the volume flow rate of liquid hydrocarbon feed to the volume of catalyst charged into the reactor, in the range 0.1 to 50 h−1.
