Hydroprocessing catalysts and their production

摘要

In a process for producing a hydroprocessing catalyst, a particulate metal oxide composition comprising an oxide of at least one first metal selected from Group 6 of the Periodic Table of the Elements can be mixed with particles of a sulfide of at least one second metal selected from Groups 8 to 10 of the Periodic Table of the Elements to produce a particulate catalyst precursor. The particulate catalyst precursor can then be sulfided under conditions sufficient to at least partially convert the particulate catalyst precursor into a layered metal sulfide having defect sites associated with the second metal sulfide.

1. A process for producing a hydroprocessing catalyst, the process comprising:
(a) forming a reaction mixture comprising a source of a first metal oxide in a protic liquid and heating the reaction mixture under hydrothermal conditions to form a particulate metal oxide composition, the first metal oxide comprising an oxide of at least one first metal selected from Group 6 of the Periodic Table of Elements; (b) mixing the formed particulate metal oxide composition with particles of a sulfide of at least one second metal selected from Groups 8 to 10 of the Periodic Table of the Elements to produce a particulate catalyst precursor; and (c) sulfiding the particulate catalyst precursor under conditions sufficient to at least partially convert the components of the particulate catalyst precursor into a layered metal sulfide having defect sites associated with the second metal sulfide.
