Publication number: 20090173665Abstract: 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: ApplicationFiled: January 3, 2008Publication date: July 9, 2009Applicant: HEADWATERS TECHNOLOGY INNOVATION, LLCInventors: Bing Zhou, Zhenhua Zhou, Zhihua Wu

Patent number: 7557057Abstract: The present invention relates to a method for synthesizing highly dispersed supported platinum catalyst. More particularly, the present invention relates to a method of synthesizing highly dispersed supported platinum catalyst comprising: dissolving a reducing agent in a solvent to produce a solution, dissolving a platinum chloride to the same solvent; adding a carbon support and platinum in a predetermined ratio to the above mixed solution, agitating the mixture, performing ultrasonic treatment, and performing heat treatment; and adding a HCl solution, agitating the mixture, separating the precipitates via filtration to produce a catalyst, and then washing the catalyst with distilled water, thereby obtaining an active highly dispersed supported platinum catalyst which has excellent electric charge activity, uniformly-sized platinum particles and relatively high specific surface area.Type: GrantFiled: August 4, 2006Date of Patent: July 7, 2009Assignee: Hyundai Motor CompanyInventors: Jong Hyun Lee, Young Min Kim, Jong heop Yi, Pil Kim, Ji Bong Joo
