Abstract: 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.

Abstract: Provided is a block copolymer having an “A” block of a functionalized hydrocarbon moiety including one or more functional end groups selected from the group consisting of: epoxides, amines, acids, acid chlorides, acid anhydrides, halogens, vinyl or vinylidene double bond, aromatic rings and thiols, and a “B” block of a functionalized polyether moiety including one or more functional end groups selected from the group consisting: epoxides, amines, acids, acid chlorides, acid anhydrides, halogens, vinyl or vinylidene double bond, aromatic rings and thiols. The end group of the polyether moiety is different than the end group of the hydrocarbon moiety, and the hydrocarbon moiety and the polyether moiety are copolymerizable therewith. Preferably, the hydrocarbon moiety is a poly-?-olefin and the polyether moiety is a polyalkylene glycol.
