  • Patent number: 8226918
    Abstract: A method of carbon monoxide (CO) removal comprises providing an oxidation catalyst comprising cobalt supported on an inorganic oxide. The method further comprises feeding a gaseous stream comprising CO, and oxygen (O2) to the catalyst system, and removing CO from the gaseous stream by oxidizing the CO to carbon dioxide (CO2) in the presence of the oxidation catalyst at a temperature between about 20 to about 200° C.
    Type: Grant
    Filed: April 26, 2006
    Date of Patent: July 24, 2012
    Assignee: The Ohio State University
    Inventors: Umit S. Ozkan, Erik M. Holmgreen, Matthew M. Yung
  • Publication number: 20100331588
    Abstract: A process and catalyst for use in the selective hydrogenation of acetylene to ethylene is presented. The catalyst comprises a layered structure, wherein the catalyst has an inner core and an outer layer of active material. The catalyst further includes a metal deposited on the outer layer, and the catalyst is formed such that the catalyst has an accessibility index between 3 and 500.
    Type: Application

  • Patent number: 7488462
    Abstract: Catalyst systems and methods provide benefits in reducing the content of nitrogen oxides in a gaseous stream containing nitric oxide (NO), hydrocarbons, carbon monoxide (CO), and oxygen (O2). The catalyst system comprises an oxidation catalyst comprising a first metal supported on a first inorganic oxide for catalyzing the oxidation of NO to nitrogen dioxide (NO2), and a reduction catalyst comprising a second metal supported on a second inorganic oxide for catalyzing the reduction of NO2 to nitrogen (N2).
