News from the Catalysis Commission

         
19-Oct-21 International Reference Zeolites are ready for delivery!
    You can now request the samples of International Reference Zeolite, which are provided by the Catalysis Commission, International Zeolite Association. The samples can be used for scientific purposes, and the results should be reported when published as scientific papers. Only shipping from the distributor in your country is required. We currently offer services in a limited number of countries, but we plan to expand to other countries as well.

    the composition of the Catalysis Commission changed and new officers were elected
      Martin Hartmann is the new Chair, and
Bert Sels is the new Co-Chair
   
30-Apr-04 At the 14th IZC in Cape Town
    Michael Stöcker,the Chair of the Catalysis Commission
      retired from the Commission, and two new members
    Graham Hutchings
Johannes Lercher
      joined the Commission
         
    The new officers of the Catalysis Commission are

    The next test reaction,
      the gas phase isomerization and hydrocracking of n-nonane, using a bi-functional catalyst (0.5 wt.-% Pt on LaNaY), is being prepared.
Preliminary experiments have been done at the University of Kaiserslautern (by Stefan Ernst) and at ChevronTexaco (by C.-Y. Chen)
         
26-Sep-02 The results of the first test reaction are now available
    The disproportionation reaction of ethylbenzene over LaNa-Y has been tested in five different laboratories and the results evaluated

  To begin with
    the Commission has been concentrating on the disproportionation of ethyl benzene catalyzed by LaNa-Y with a given degree of metal exchange.
      This reaction is an acid-catalyzed process with a well-defined product distribution under the specified conditions.
         
  Reactions that highlight the unique catalytic properties
    of various modified porous materials, both in the gas phase and the liquid state, are under consideration for further investigation.
         
  The results of this work should demonstrate
    that well-defined catalytic test reactions using zeolites as catalysts yield comparable results independent of where and by whom the tests are performed, as long as the same experimental conditions are used.
