Abstract
This invention relates to a process for the preparation of promoted molybdenum and tungsten sulfide catalysts, the catalysts prepared by such process, and to the use of such catalysts for hydroprocessing processes, particularly hydrotreating. More particularly, this invention relates to the preparation and use of promoted catalysts useful for hydroprocessing processes such as hydrotreating wherein said catalysts are formed by treating molybdenum and tungsten sulfide-containing material (which may be supported) with a low valence promoter metal selected from transition metals particularly the group of Fe, Co, Ni.
