Abstract
The invention relates to a method of preparing a catalyst comprising a) preparation of a support comprising 0.2 to 30 wt % of zeolite NU-86 and from 70 to 99.8 wt % of a porous mineral matrix, the percentages by weight being expressed relative to the total weight of said support, b) impregnation of the support prepared according to step a) with at least one solution containing at least one precursor of at least one metal selected from group VIII metals and group VIB metals, used alone or as a mixture, c) at least one ripening step, and d) at least one drying step carried out at a temperature below 150° C., without a subsequent calcining step. The present invention also relates to a process for hydrocracking hydrocarbon feeds using the catalyst prepared according to the method of preparation according to the invention.
