1. A process for the hydroconversion of a lower quality hydrocarbonaceous feedstock, wherein the process comprises:
converting a precursor composition into an active slurry catalytic phase, and hydroconverting the lower quality hydrocarbonaceous feedstock using the active slurry catalytic phase; and wherein the precursor composition comprises at least one organometallic coordination compound of formula C1C2MLn (I), where M is a transition metal selected from group IIA, IIIB, IVB, VB, VIB, VIIB, VIII, IB or IIB of the periodic table of elements, and wherein M is not Fe, —C1 and —C2 are monocyclic or polycyclic aryl hydrocarbon ligands that are pi-bonded to M, —C1 and —C2 being the same or different, each of —C1 or —C2 comprising from 0 to 5 substituents R, each substituent R being the same or different, R being selected from:
a C3-C8 substituted or unsubstituted, monocyclic or polycyclic ring structure that is partially unsaturated, unsaturated or aromatic, fused or not fused to the ligand —C1 or —C2,a C3-C8 substituted or unsubstituted, partially unsaturated or unsaturated, linear or branched, alicyclic hydrocarbyl radical,a C1-C8, substituted or unsubstituted, linear or branched, saturated hydrocarbyl radical, —C1 and —C2 being independent or connected via at least one substituent R, -L is a ligand that is sigma-bonded to M, n is an integer equal to 0 to 3, each -L is, independently, a univalent ligand. |
