Abstract
The present invention relates to a hydrocracking process including contacting a hydrocarbon feed with a catalyst which is carried out at a pressure of at least 2 MPa, a temperature of at least 230° C., using a quantity of hydrogen of at least 100 Nl hydrogen/l of feed and with an hourly space velocity of 0.1-10 h−1. The catalyst includes0.1-99.7% by weight of at least one alumina matrix;0.1-80% by weight of at least one globally non dealuminated Y zeolite with a lattice parameter of more than 2.438 nm, a global SiO2/Al2O3 mole ratio of less than 8, and a framework SiO2/Al2O3 mole ratio of less than 21 and more than the global SiO2/Al2O3 mole ratio;0.1-30% by weight of at least one group VIII metal and/or 1-40% by weight of at least one group VIB metal (% oxide);0.1-20% by weight of at least one promoter element selected from the group formed by boron and silicon (% oxide);0-20% by weight of at least one group VIIA element;0-20% by weight of phosphorous (% oxide); and0.1-20% by weight of at least one group VIIB element.
