The present invention is based on the discovery that certain transition metal containing complexes thermally decompose to form solids containing the transition metal, sulfur and carbon and that these transition metal, sulfur and carbon containing solids are particularly suitable as catalysts for hydrodesulfurization, hydrodenitrogenation and aromatics hydrogenation. The transition metal complexes that are thermally decomposed to novel catalysts are complexes of the type represented by the general formula MLn3, wherein M is selected from Mo, W, Re and mix...
A process for hydrotreating petroleum feedstocks to lower the sulfur, nitrogen and aromatic contents thereof comprising: contacting a petroleum feedstock at an elevated temperature of above about 200°C. and in the presence of hydrogen with a catalyst formed by heating a precursor MLn3 wherein M is a metal selected from Mo, W, Re and mixtures thereof, n represents the total charge of the metal complex and is 0, -1, or -2; L is selected from dithiolene or aminobenzenethiolate ligands having the formula [Figure] [Figure] wherein R is an alkyl, aryl or alkyl...
