Preparing a catalyst comprising at least one hydro-dehydrogenating element comprising elements of non-noble group VIB and/or group VIII of the periodic table, and a support comprising at least one porous mineral matrix and dealuminated zeolite (USY), comprises : (a) preparing a dealuminated zeolite; (b) depositing on the dealuminated zeolite of the nickel element in an amount of 0.5-3 wt.%; (c) mixing with a porous mineral matrix and forming to obtain the support; (d) introducing at least one hydro-dehydrogenating element on the matrix; and (e) drying and calcining the product. Preparing a catalyst comprising at least one hydro-dehydrogenating element comprising elements of non-noble group VIB and/or Group VIII of the periodic table, and a support comprising at least one porous mineral matrix and at least one dealuminated zeolite USY, comprises : (a) preparing a dealuminated zeolite having an overall atomic ratio of silicon to aluminum of 2.5-10, a weight fraction of extra network aluminum atom of greater than 10 mass% with respect to the total mass of the aluminum present in the zeolite, a mesoporous volume measured by nitrogen porosimetry of greater than 0.07 ml.g -> 1>and a crystalline parameter (a0) of the unit cell greater than 24.28 A[deg] ; (b) depositing on the dealuminated zeolite of the nickel element in an amount of 0.5-3 wt.% with respect to the total weight of the zeolite; (c) mixing with a porous mineral matrix and forming to obtain the support; (d) introducing at least one hydro-dehydrogenating element on the matrix by (i) adding at least one compound of the element during forming to introduce at least one part of the component, and (ii) impregnating the support with at least one compound of the element; and (e) drying and calcining the obtained final product. An independent claim is included for process for hydrocracking and/or hydrotreating of hydrocarbon feeds using a catalyst, where the catalyst is in sulfate form. |
