  • Process for preparation of a MEL-structural-type zeolite
    Patent number: 7867473
    Abstract: A process for preparation of a MEL-structural-type zeolite that comprises at least the following stages: i) the mixture, in aqueous medium, of at least one source of at least one tetravalent element and at least one nitrogen-containing organic radical of the formula: in which n represents the methylene group number (CH2) and is equal to 6 or 7, and R1 and R2 represent alkyl groups that have 2 to 7 carbon atoms, ii) the hydrothermal treatment of said mixture until said MEL-structural-type zeolite is formed, is described.
    Type: Grant

    Date of Patent: January 11, 2011
    Assignee: IFP Energies Nouvelles
    Inventors: Antoine Fecant, Nicolas Bais
  • IZM-1 crystalline solid and a process for its preparation
    Patent number: 7771703
    Abstract: The invention concerns a crystalline solid designated IZM-1, which has the X ray diffraction diagram given below. Said solid has a chemical composition, expressed as the anhydrous base in terms of moles of oxides by the formula XO2: aY2O3; bM2/nO where X represents at least one tetravalent element, Y represents at least one trivalent element and M is an alkali metal and/or an alkaline-earth metal with valency n, a and b respectively representing the number of moles of Y2O3 and M2/nO; a is in the range 0 to 0.02 and b is in the range 0 to 1.

    Assignee: Institut Francais du Petrole
    Inventors: Emmanuelle Guillon, Johan Mariens, Nicolas Bais, Antoine Fecant
  • Process for preparation of ZBM-30-type zeolites using a diammonium ether-type compound as an organic structuring agent
    Patent number: 7622099
    Abstract: The invention relates to a process for preparation of a zeolite that is selected from among the ZBM-30, ZSM-48, EU-2 and EU-11 zeolites, comprising the mixing in an aqueous medium of at least one source of at least one element X (Si and/or Ge) and at least one nitrogen-containing organic compound Q. Said nitrogen-containing organic compound Q is selected from among the compounds comprising at least one ether group and two terminal ammonium groups and their precursors.
