1. A method for manufacture of catalyst material comprising:
providing a support material in the form of powder, particulates, granules, extrudates or a combination of said forms, the support material being porous and including outer surfaces and pore inner surfaces for receiving catalytically active components;
contacting the support material with a promotor component composition including one or more oxidized disulfide oil (ODSO) compounds to produce enhanced support material; and
contacting the enhanced support material with an aqueous solution of the catalytically active components, precursors of the catalytically active components or a combination thereof, as an impregnating solution to disperse the catalytically active components on the outer surfaces and pore inner surfaces of the support material and transfer thereto to form support material loaded with the catalytically active components.
