Abstract
The invention relates to a nickel tungsten bulk catalyst, to a process for the manufacture of said catalyst and to the use of said catalyst for the hydrotreatment, in particular the hydrodesulphurisation and hydrodenitrogenation of hydrocarbon feedstock. The catalyst comprises nickel tungsten metal oxidic particles obtainable by a process comprising forming a slurry of a first solid metal compound comprising Group VNI metal nickel and a second solid metal compound comprising Group VIB metal tungsten in a protic liquid, reacting the first and second solid metal compounds at elevated temperature whereby the first and second solid metal compounds remain at least partly in the solid state during the entire reaction to form the nickel tungsten oxidic bulk catalyst.
