1. A slurry-phase catalyst composition comprising a disulfide oil and a first metal complex comprising:
at least one transition metal selected from the group consisting of molybdenum, cobalt, nickel, tungsten, iron, and combinations of these; and
a plurality of ligands bonded to the at least one transition metal, where:
the plurality of ligands comprises a first ligand selected from the group consisting of dimethylsulfide, dimethyldisulfide, diethylsulfide, diethyldisulfide, methylethylsulfide, methylethyldisulfide, and combinations thereof; and
the transition metal is bonded to a sulfur atom of the first ligand, and
where a concentration of the first metal complex in the slurry-phase catalyst composition is from 100 parts per million by weight (ppmw) to 10,000 ppmw and the balance is disulfide oil.
