Patent number: 8476182Abstract: A method to obtain a catalyst of transition metals supported on a carbonaceous material, via impregnation, with a solution of metal-thiourea complex, obtained from precursor salts. The formation of the sulfur on the surface of the support occurs through the thermal decomposition of the complex. The obtained catalysts are applicable toward the direct liquefaction of coal.Type: GrantFiled: March 1, 2011Date of Patent: July 2, 2013Inventors: Jose De Jesus Diaz Velasquez, Yazmin Yaneth Agamez Pertuz, Luis Ignacio Rodriguez Varela, Orlando Hernandez Fandino, Oscar Andres Villaba Varon, Jose Alexandre Jimenez Sanchez

Patent number: 8476187Abstract: The present invention details a process for producing a catalyst powder. The steps of the process include preparing catalyst slurry, drying, pyrolyzing, and calcining the catalyst slurry to obtain a calcined catalyst powder. The catalyst slurry comprises a catalyst, a liquid carrier, a templating agent, and a catalyst substrate. The catalyst slurry is dried to obtain a raw catalyst powder. The raw catalyst powder is heated in a first controlled atmosphere to obtain a pyrolyzed catalyst powder and the pyrolyzed catalyst powder is calcined in a second controlled atmosphere to obtain a calcined catalyst powder. A method of fabricating a catalyst surface and catalytic converter using the prepared catalyst powder is also illustrated.Type: GrantFiled: January 6, 2010Date of Patent: July 2, 2013Assignee: General Electric CompanyInventors: Daniel George Norton, Larry Neil Lewis, Elliott West Shanklin, Frederic Joseph Klug, Venkat Subramaniam Venkataramani, Robert Joseph Lyons, Dan Hancu, Benjamin Hale Winkler, Hrishikesh Keshavan

Publication number: 20130123099Abstract: A method for producing an adsorbent, having the steps of combining a first sludge and a second material to form a mixture, thermally drying the mixture, and pyrolizing the mixture using at least four temperature zones wherein each temperature zone is set between about 600° C. and 1,100° C. The first sludge is a municipal sludge or an industrial sludge, and the second material is a compost material or one of municipal sludge or industrial sludge differing from the first sludge. The compost material is at least one of tobacco waste, waste paper and wood char, or a combination thereof. Further, the drying can happen in two stages. Each stage can include two separate temperatures.Type: ApplicationFiled: May 8, 2012Publication date: May 16, 2013Applicant: Research Foundation of the City University of New YorkInventor: Teresa J.

Patent number: 8420043Abstract: A nano-crystal diamond film synthesized on a substrate and containing, as a major component, nano-crystal diamond having a grain diameter from 1 nm to less than 1000 nm. This nano-crystal diamond film can be formed on a substrate by means of a plasma CVD method using a raw material gas containing a hydrocarbon and hydrogen, allowing the formation of the nano-crystal diamond film to take place outside the plasma region. This nano-crystal diamond film is applicable to the manufacture of an electrochemical device, an electrochemical electrode, a DNA chip, an organic electroluminescent device, an organic photoelectric receiving device, an organic thin film transistor, a cold electron-emission device, a fuel cell and a catalyst.Type: GrantFiled: November 14, 2006Date of Patent: April 16, 2013Assignees: Toppan Printing Co., Ltd., National Institute for Materials ScienceInventors: Hidenori Gamo, Toshihiro Ando
