<p>The invention concerns a method for preparing catalysts, containing metals of groups VI and VIII in the same molecule on the support. Metals of groups VI and VIII are introduced in the form of a compound of formula Mx A B11 O40 M' C¿(z - 2x)?, t H2O in which M is cobalt and/or nickel, A is phosphorus, silicon and/or boron, B is molybdenum and/or tungsten and M' is cobalt, nickel, iron, copper and/or zinc, x has a value between 0 and 4.5, z a value between 7 and 9 depending on the pH of the synthesis, t is a whole number varying between 5 to 29 and C is a H?+¿ ion and/or an alkylammonium ion of the type (NR¿1?R2R3R4)?+¿, with R¿1?, R2, R3 and R4, identical or different, corresponding either to a hydrogen atom or an alkyl group. The catalysts obtained are used for hydrotreating hydrocarbon feedstock.</p> |
