BULK CATALYST COMPOSITION COMPRISING BULK METAL OXIDE PARTICLES

摘要

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 1 mum 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.
