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 method of making a slurry-phase catalyst composition, the method comprising:
- mixing a metal complex and a disulfide oil in a mixing vessel to form a catalyst composition precursor;
- heating the catalyst composition precursor to an elevated temperature sufficient to dissolve at least a portion of the metal complex in the disulfide oil to form a mixed catalyst composition, wherein the mixed catalyst composition comprises both a liquid component and a solid component;
- and
- transferring at least a portion of the mixed catalyst composition to a slurry-phase hydrocracking unit to form the slurry-phase catalyst composition.
1 more element
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 metal complex is dissolved in the disulfide oil to form a mixed catalyst composition;
- and
- at least a portion of the mixed catalyst composition is transferred to a slurry-phase hydrocracking unit to form the slurry-phase catalyst composition.
