Patent

CA 2707310

The invention relates to a process for preparing bulk metal oxide particles comprising the steps of combining in a reaction mixture (i) dispersible nanoparticles having a dimension of less than about lµm upon being dispersed in a liquid, (ii) at least one Group VIII non-noble metal compound, (iii) at least one Group VIB metal compound, and (iv) a protic liquid; and reacting the at least one Group VIII non-noble metal compound and the at least one Group VIB metal in the presence of the nanoparticles. It also relates to bulk metal hydroprocessing catalysts obtainable by such method.

L'invention concerne un procédé de préparation de particules d'oxyde de métal brutes comprenant les étapes consistant à combiner, dans un mélange de réaction, (i) des nanoparticules dispersibles présentant une dimension inférieure à 1 µm lors de leur dispersion dans un liquide, (ii) au moins un composé de métal non noble du groupe VIII, (iii) au moins un composé de métal du groupe VIB et (iv) un liquide protique; et à faire réagir le ou les composés de métal non noble du groupe VIII et le ou les métaux du groupe VIB en présence de nanoparticules. L'invention concerne également des catalyseurs d'hydrotraitement de métal bruts pouvant être obtenus par un tel procédé.
