  • Catalyst based on ferrierite/iron for catalytic reduction of nitrous oxide
    Patent number: 7238641
    Abstract: A catalyst for reducing the nitrous oxide content in gas, which operates at relatively low temperatures, the activity of which is relatively insensitive to the presence of water vapor and which is highly resistant to hydrothermal degradation, is prepared from ferrierite exchanged with iron. Application to the treatment of gases with a low N2O content, such as gases resulting from plants for the manufacture of nitric acid, and of gases with a high N2O content, which are emitted during oxidations of organic compounds by nitric acid.
    Type: Grant
    Filed: December 1, 2003
    Date of Patent: July 3, 2007
    Assignees: Grande-Paroisse S.A., Institut Regional des Matariaux Avances (IRMS)
    Inventors: Christian Hamon, Karine Malefant, Geneviève Neveu, legal representative, Bernard Neveu, deceased
  • Method for simultaneously abating nitric oxides and nitrous oxides in gases containing them
    Patent number: 6890501
    Abstract: The invention concerns a method for purifying flue gases before they are released into the atmosphere of their nitrogen oxides N2O and NOx by reaction with ammonia by causing them to circulate at temperatures between 200 and 600° C. on a catalyst based on beta-zeolite loaded with iron. The invention is particularly useful for treating tail gases from factories producing nitric acid.
    Type: Grant

  • Catalytic reduction of nitrous oxide content in gases
    Patent number: 6682710
    Abstract: A process and catalyst for reducing the nitrous oxide content in gas, which operates at relatively low temperatures, the activity of which is relatively insensitive to the presence of water vapour and which is highly resistant to hydrothermal degradation, is prepared from ferrierite exchanged with iron. Application to the treatment of gases with a low N2O content, such as gases resulting from plants for the manufacture of nitric acid, and of gases with a high N2O content, which are emitted during oxidations of organic compounds by nitric acid.
