1. A hydro-processing co-catalyst composition, consisting essentially of:
- a liquid carrier comprising oil; and
co-catalyst particles in admixture with the liquid carrier comprising oil, wherein;
the co-catalyst particles are hydrophilic, andthe co-catalyst particles have a mean particle size between about 2 microns and 100 microns;
the liquid carrier comprising oil has a boiling point ranging from about 350°
F. to 1125°
F.,the co-catalyst particles are suspensible in the liquid carrier, and the co-catalyst composition comprises from about 5 wt. % to 50 wt. % of the co-catalyst particles and from about 50 wt. % to 95 wt. % of the liquid carrier comprising oil.

Abstract
A hydroprocessing co-catalyst composition may comprise in an embodiment a first component comprising co-catalyst particles and a liquid carrier, and a second component comprising a dispersant and a dispersant diluent. The co-catalyst particles may be in the micron size range, and the dispersant may promote dispersion of the co-catalyst particles in materials such as the liquid carrier, the dispersant diluent, and combinations thereof. Methods of introducing a hydroprocessing co-catalyst composition into a hydroprocessing system are also disclosed.
