Abstract
The invention relates to a hydrocracking catalyst that contains at least one metal of group VIB, and/or at least one metal of group VIII of the periodic table, an alumina matrix, phosphorus, optionally at least one element from group VIIA (fluorine), and a zeolite Y that is not fully dealuminificated, with a crystalline parameter that is greater than 2,438 nm, an overall SiO.sub.2 /Al.sub.2 O.sub.3 ratio that is less than 8, and a framework SiO.sub.2 /Al.sub.2 O.sub.3 ratio that is less than 21 and greater than the overall SiO.sub.2 /Al.sub.2 O.sub.3 ratio. The invention also relates to a process for hydrocracking with this catalyst, in particular at low pressure of 7.5 to 11 MPa.
