A fuel cell produced using the supported catalyst has improved efficiency.Type: GrantFiled: February 21, 2007Date of Patent: August 9, 2011Assignee: Samsung SDI Co., Ltd.Inventors: Chan-ho Pak, Dae-jong Yoo, Sang-hoon Joo, Hyuk Chang, Seol-ah Lee

Publication number: 20110184216Abstract: The present invention relates to a process of formulating and preparing supported multi-metal catalysts based on metal oxides and inorganic salts of metals. The impregnation technique is employed by two methods: the slurry method and the modified-pH variation method, which are used in two steps for obtaining the catalyst. The present invention also relates to a process called Glycerol to Propene (GTP) process, corresponding to the transformation of glycerol or glycerin to propene. The reaction involved in the process of the present invention is the selective hydrogenation of glycerin, which takes place by contact of the charge of glycerin carried by hydrogen in a continuous stream system on the catalytic bed containing multi-metal catalysts, specifically prepared for this purpose.Type: ApplicationFiled: June 24, 2009Publication date: July 28, 2011Inventors: Jose Carlos Sousa Fadigas, Rossano Gambetta, Cláudio José Araújo Mota, Valter Luiz da Conceicão Goncalves

Patent number: 7968489Abstract: A new method for preparing a supported catalyst is herein provided. Carbon nanotubes are functionalized by contacting them with an oxidizing agent to form functionalized carbon nanotubes. A metal catalyst is then loaded or deposited onto the functionalized carbon nanotubes. The mixture is then extruded to form the supported catalyst comprising a carbon nanotube structure containing metal catalyst more evenly dispersed within the internal structure of the carbon nanotube structure.Type: GrantFiled: August 20, 2007Date of Patent: June 28, 2011Assignee: Hyperion Catalysis International, Inc.Inventors: Jun Ma, David Moy, Asif Chishti, Jun Yang
