Disclosed are hydroconversion processes catalyzed by aromatic-metal chelate compositions which are deficient in hydrogen, are cross-linked, and which are comprised of two or more heteroatoms, wherein at least one of the heteroatoms are part of a 5 to 6 member heterocyclic ring, and wherein the metal constituent is selected from Groups III, IVB, VB, VIB, VIIB, and VIII of the Periodic Table of the Elements, and the heteroatom is selected from sulfur, oxygen, and nitrogen.
In a hydroconversion process for treating hydrocarbonaceous oils derived from petroleum, oil-shale, tar sand, and coal, conducted in the presence of hydrogen in which said hydrocarbonaceous feed is either refined without substantial change in the boiling range of the oil, or is converted to lower boiling products, the improvement which comprises performing the hydroconversion in the presence of an unsupported catalyst formed by chelating a metal component with an aromatic compound and heating said metal component and aromatic compound above about 450°C. ...
