Catalyst/Adsorbents/Membranes Characterization
  • 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:

Multiscale Modeling

Developing experimentally-validated high-fidelity multiscale numerical models that enable exploration of a large design space in a cost effective manner is a computationally exhaustive exercise. Sophisticated numerical methodologies such as Molecular Simulation and CFD, used in the different projects of Theme 3, needs an equally sophisticated hardware in order shorten the execution time of the numerical experiments and allow for a full investigation of the different inputs related to the different processes under study.

CFD calculations and Part of the Molecular Dynamics (MD) simulations have been run on workstations and KU HPC. The computing power of CeCaS is continuously updating and increasing with  high-end Workstations that will increase the number of numerical experiments conducted for both MD and CFD.

    Some of the units under this category are:

Workstations currently used

  • Two Precision 5820 Tower (Intel Xeon w-2104 2.0 GHz)
  • Three Precision 7920 Tower (Intel Xeon Gold 6248 2.5 GHz)


  • CeCaS Center uses the Core Analytical Facilities available at Arzanah & ADRIC Buildings at SAN Campus, the core labs available at Masdar City and Main Campuses as well as the KU HPC.
Catalysts/Adsorbents/Membranes Evaluation/Activity

Evaluation of a catalyst/adsorbent or catalytic membrane is of pivotal importance in the catalysis and separation cycle.

Some of the units under this category are:

  • Sulfur-containing species adsorption unit: custom made breakthrough apparatus for monitoring the capacity of an adsorbent towards an adsorbate.
  • Computerized Chemical reactions operating up to high pressure (100 bar) (PID, Micromeritics Effi) (2 units): Fully automated solid-gas catalytic reactors with the capacity of in situ characterization studied (TPO, TPD, TPR). The exhaust stream is recorded through Mass Spectrometry and/or GC/MS.
  • Membrane separation setups: Single gas and mixture permeability units with GC integrated (SRI Instruments, USA) for evaluation of separation performance of membranes. Polymeric, mixed matrix membranes, and inorganic membranes can be evaluated of various configurations (flat, hollow fibers) and sizes.
