Patent ID: 7951745

Claim:
An oil-soluble catalyst for hydrocracking a hydrocarbon feedstock containing polynuclear-aromatics, comprising: an oil-soluble catalyst complex comprised of: a first catalytic metal atom selected from the group consisting of group VIB metals, group VIIIB metals, and combinations thereof; a second catalytic metal atom selected from the group consisting of group VIB metals, group VIIIB metals, and combinations thereof; and an organic ligand bonded with the first and second catalytic metal atoms, wherein the organic ligand is comprised of: an aromatic group; a first ligand spacing group bonded to the aromatic group, the ligand spacing group having an atom bonded to the first metal atom and another atom bonded to the aromatic group and providing separation of 2-6 atoms between the first metal atom and the aromatic group; and a second ligand spacing group bonded to the aromatic group, the ligand spacing group having an atom bonded to the second metal atom and another atom bonded to the aromatic group and providing separation of 2-6 atoms between the second metal atom and the aromatic group.
