Patent number: 8445399Abstract: Hydrocarbon-soluble molybdenum catalyst precursors include a plurality of molybdenum cations that are each bonded with a plurality of organic anions to form an oil soluble molybdenum salt. A portion of the molybdenum atoms are in the 3+ oxidation state such that the plurality of molybdenum atoms has an average oxidation state of less than 4+, e.g., less than about 3.8+, especially less than about 3.5+. The catalyst precursors can form a hydroprocessing molybdenum sulfide catalyst in heavy oil feedstocks. The oil soluble molybdenum salts are manufactured in the presence of a reducing agent, such as hydrogen gas, to obtain the molybdenum in the desired oxidation state. Preferably the reaction is performed with hydrogen or an organic reducing agent and at a temperature such that the molybdenum atoms are reduced to eliminate substantially all molybdenum oxide species.Type: GrantFiled: November 11, 2009Date of Patent: May 21, 2013Assignee: Headwaters Technology Innovation, LLCInventors: Zhihua Wu, Zhenhua Zhou, Bing Zhou

Patent number: 8142645Abstract: Hydrocarbons containing polynuclear aromatics, such as cycle oil and pyrolysis fuel oil (PFO), are upgraded using an catalyst complex that selectively cracks the polynuclear aromatic compounds to form higher value mono-aromatic compounds, such as benzene toluene, xylenes and ethyl benzene (i.e., BTX). The catalyst complexes include a catalytic metal center and a plurality of organic ligands. During the hydrocracking procedure, the organic ligand preserves one of the aromatic rings of the polynuclear aromatic compounds while the catalytic metal breaks the other aromatic rings thereby yielding a monoaromatic compound.Type: GrantFiled: January 3, 2008Date of Patent: March 27, 2012Assignee: Headwaters Technology Innovation, LLCInventors: Bing Zhou, Zhenhua Zhou, Zhihua Wu

Patent number: 8097149Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.Type: GrantFiled: June 17, 2008Date of Patent: January 17, 2012Assignee: Headwaters Technology Innovation, LLCInventors: Zhihua Wu, Zhenhua Zhou, Bing Zhou

Patent number: 7951745Abstract: Oil soluble catalysts are used to convert polynuclear aromatic compounds in a hydrocarbon feedstock to higher value mono-aromatic compounds. The catalyst complex includes a catalytic metal center that is bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The ligands include an aromatic ring and a ligand spacer group. The ligand spacer group provides spacing of 2-6 atoms between the metal center and the aromatic ring. The spacing between the aromatic group and the catalytic metal center advantageously allows the catalyst to selectively crack polynuclear aromatic rings while preserving one of the aromatic rings, thereby increasing the content of mono-aromatic compounds in the hydrocarbon feedstock.Type: GrantFiled: January 3, 2008Date of Patent: May 31, 2011Assignee: Wilmington Trust FSBInventors: Bing Zhou, Zhenhua Zhou, Zhihua Wu

Patent number: 7842635Abstract: Bimetallic catalyst precursors are manufactured from a plurality of molybdenum atoms and a plurality of atoms of a secondary transition metal (e.g., one or more of cobalt, iron, or nickel). The molybdenum atoms and the secondary transition metal atoms are each bonded with a plurality of organic anions (e.g., 2-ethyl hexanoate) to form a mixture of an oil-soluble molybdenum salt and an oil-soluble secondary transition metal salt. The molybdenum and/or the secondary transition metals are preferably reacted with the organic agent in the presence of a strong reducing agent such as hydrogen. To obtain this mixture of metal salts, an organic agent is reacted with the molybdenum at a temperature between about 100° C. and about 350° C. The secondary transition metal is reacted with the organic agent at a different temperature, preferably between 50° C. and 200° C. The metal salts are capable of forming a hydroprocessing metal sulfide catalyst in heavy oil feedstocks.Type: GrantFiled: August 1, 2006Date of Patent: November 30, 2010Assignee: Headwaters Technology Innovation, LLCInventors: Bing Zhou, Zhenhua Zhou, Zhihua Wu
