Patent number: 8992799Abstract: A polymer composite composed of a polymerized mixture of functionalized carbon nanotubes and monomer which chemically reacts with the functionalized nanotubes. The carbon nanotubes are functionalized by reacting with oxidizing or other chemical media through chemical reactions or physical adsorption. The reacted surface carbons of the nanotubes are further functionalized with chemical moieties that react with the surface carbons and selected monomers. The functionalized nanotubes are first dispersed in an appropriate medium such as water, alcohol or a liquefied monomer and then the mixture is polymerized. The polymerization results in polymer chains of increasing weight bound to the surface carbons of the nanotubes. The composite may consists of some polymer chains imbedded in the composite without attachment to the nanotubes.Type: GrantFiled: October 26, 2005Date of Patent: March 31, 2015Assignee: Hyperion Catalysis International, Inc.Inventors: Chunming Niu, Lein Ngaw

Patent number: 8920635Abstract: Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organo sulfur compounds.Type: GrantFiled: January 14, 2013Date of Patent: December 30, 2014Assignees: Saudi Arabian Oil Company, Boreskov Instutite of CatalysisInventors: Abdennour Bourane, Omer Refa Koseoglu, Zinfer Ismagilov, Svetlana Yashnik, Mikhail Kerzhentsev, Valentin Parmon

Patent number: 8906227Abstract: Desulfurization of hydrocarbon feeds is achieved by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions; a flashing column downstream of the hydrodesulfurization reaction zone fractionates the effluent to obtain a first fraction which contains refractory organosulfur compounds and a second fraction that is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organosulfur compounds.Type: GrantFiled: January 15, 2013Date of Patent: December 9, 2014Assignees: Suadi Arabian Oil Company, Boreskov Institute of CatalysisInventors: Abdennour Bourane, Omer Refa Koseoglu, Zinfer Ismagilov, Svetlana Yashnik, Mikhail Kerzhentsev, Valentin Parmon
