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.

Abstract: Embodiments of the disclosure include processes for hydroconversion of hydrocarbon feedstocks in ebullated bed reactor systems. In particular, the systems comprise two or more ebullated bed reactors comprising catalyst particles, one or more inter-stage separation vessels, which are in fluid communication, and allow for the introduction of an additional solvent into the system between the final inter-stage separation vessel and the final ebullated bed reactor in the flow path. The processes include the addition of a solvent comprising water to an inter-stage liquid product prior to contact with the final ebullated bed reactor, which improves catalytic performance.
