1. A process for forming a supported catalyst, which process comprises
I) bringing together components in any of the following combinations:
a-i) a carrier, one or more monomer species, a polar solvent, and optionally an initiator,
b-i) a carrier, one or more monomer species, at least one phosphorus compound, at least one Group VIB metal compound, and at least one Group VIII metal compound, and optionally an initiator, or
c-i) a carrier and an impregnation solution, forming an impregnated carrier, followed by mixing the impregnated carrier with one or more monomer species and optionally an initiator,
to form a monomer-containing mixture, where said monomer species is soluble in the polar solvent and has carbon-carbon unsaturation and at least one functional group comprising at least one heteroatom; and
II) polymerizing at least a portion of said monomer species in the monomer-containing mixture to form a polymerized product;
III) when I) does not include at least one phosphorus compound, at least one Group VIB metal compound, and at least one Group VIII metal compound, either
a-iia) contacting an impregnation solution and the monomer-containing mixture during the polymerizing in II), or
a-iib) contacting the polymerized product and an impregnation solution;
to form a supported catalyst, where the molar ratio of phosphorus to Group VIB metal is about 1:1.5 to less than about 1:12, where the molar ratio of the Group VIB metal to the Group VIII metal is about 1:1 to about 5:1, where said impregnation solution comprises a polar solvent, phosphorus, at least one Group VIB metal, and at least one Group VIII metal, where a polymer is formed during the polymerizing and the polymer has a carbon backbone, and comprises functional groups having at least one heteroatom, and the polymer loading is about 1.5 wt % or more, relative to the total weight of the other components in the catalyst.
