ABSTRACT:
The invention relates to a process for the preparation of a shaped bulk catalyst comprising metal oxide particles comprising one or more Group VIII metals and two or more Group VIB metals which process comprises the steps of providing first metal oxidic particles comprising one or more first Group VIII metals and one or more first Group VIB metals, providing separately prepared second metal oxidic particles comprising one or more second Group VIII metals and one or more second Group VIB metals, wherein the composition of Group VIB and Group VIII metals in the first and second metal oxidic particles are different, combining the first and second metal oxidic particles before and/or during shaping and shaping the combined first and second metal oxide particles to form a shaped bulk catalyst. The invention further relates to the shaped bulk catalyst obtainable with the process In sulphided or unsulphided form and the use thereof in hydroprocessing.
