Abstract
This disclosure relates to slurry-phase catalyst compositions comprising a metal complex and disulfide oil, and methods of making said compositions in slurry-phase hydrocracking units.
Claims20
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.
