1. A slurry-phase catalyst composition comprising:
a metal complex; and
a disulfide oil;
wherein:
the disulfide oil is a reaction product of a mercaptan oxidation reaction;
the disulfide oil comprises oils having the formula R—S—S—R′, where R and R′ are independently C1-C20 hydrocarbon chains;
at least 20 wt. % of the metal complex is dissolved in the disulfide oil to form a mixed catalyst composition;
at least a portion of the mixed catalyst composition is transferred to a slurry-phase hydrocracking unit to form the slurry-phase catalyst composition; and
the slurry-phase catalyst composition is a homogenous catalyst.
