Abstract
The invention provides a method for preparing catalysts, containing metals of groups VI and VIII on a carrier. The metals of groups VI and VIII metals are introduced in the form of a compound of formula M.sub.x A B.sub.12 O.sub.40 in which M is cobalt and/or nickel, A is phosphorus, silicon and/or boron, B is molybdenum and/or tungsten and x is 2 or more, 2.5 or more, or 3 or more depending on whether A is respectively phosphorus, silicon or boron. The catalysts thus obtained are useful for hydro-treating hydrocarbon feedstocks.
