Catalyst/Adsorbents/Membranes Characterization

June 16, 2020
  • A large variety of equipment for characterization and performance evaluation are available. These include systems to evaluate physicochemical characteristics of (nano)materials, catalysts, adsorbents, and membranes, textural features and porosity, surface properties and reactivity, catalytic conversion beds and systems for various reactions and at a variety of conditions, adsorption evaluation systems using real mixtures, and membrane separation setups (Theme 1 and Theme 2).

 

Some of the noteworthy equipment under this category are:

    • Intelligent Gravimetric Analyzer (IGA, Hiden, UK): Static and dynamic modes of adsorption with integrated vapor generator and mass spectrometer (working range: cryo to 500 °C/ 10-6 mbar to 20 bar).
    • Automated Breakthrough Reactor (ABR) coupled to DSMS (Hiden, UK): Breakthrough reactor & interface.
    • 3 Flex Multiport Physisorption/Micropore Analyzers (Micromeritics, USA): Fully automated, high throughput, 3-port physical adsorption analyzers (two units).
    • Chemisorption unit (Quantachrome Instruments): ChemBET PULSAR TPR/TPD/TPO for chemisorption analysis.
    • Chemisorption Units (Autochem 2920, Micromeritics): Fully automated chemisorption unit for running temperature programmed related techniques (TPO, TPR, TPD)
    • Magnetic susceptibility unit: Electromagnet Model (EMU-75T), Constant Power Supply(DPS-175), Digital Gauss meter, and Digital Balance.
    • Diffraction (XRD, PANalytical Empyrean): Key technique to study the crystalline nature of the synthesized catalysts/membranes.  
    • Vibrational Spectroscopy (FTIR, Bruker Vertex 80v): To study the fundamental structure (functional groups) of the prepared catalysts/membranes
    • Raman Spectroscopy (Witec Alpha 300 RAS): Complementary technique for the structural analysis of the prepared catalysts/membranes.
    • Nuclear Magnetic Resonance (NMR, BRUKER AVANCE III 400 SPECTROMETER): a very powerful tool for structural studies both in wet and solid state.
