<p>The invention concerns a catalyst containing at least a matrix, a partially amorphous zeolite Y, optionally at least a metal selected from the group consisting of metals of group VIB and group VIII of the periodic table, optionally at least en element selected from the group consisting of phosphorus, boron and silicon, optionally at least an element of group VIIA, and optionally at least an element of group VIIB. The partially amorphous zeolite Y has a peak rate less than 0.4, a crystalline fraction, expressed with respect to a reference zeolite in sodic from, which is less than 60 %. The invention also concerns the use of said catalyst for hydroconversion, in particular for hydrocracking and hydrorefining hydrocarbon feedstocks.</p> |
