Equipment and test benches at the Exhaust Gas Center Karlsruhe

In the following you will find only a short overview of our methods, plants and analytics; we will be happy to give you more detailed information  upon request.

 

Modern catalyst preparation methods

  • High-Output Catalyst Synthesis Platform 
  • Double-Flame-Spray-Pyrolysis setup for material preparation

 

Equipment for Analysis

  • Laser spectroscopy  (LII to stody soot particles; LIF, Raman and IR to study in a time and spatially resolved manner gaseous species and tempearture profiles along catalyst coated monolith channels)
  • Conventional catalyst characterization techniques: H2-TPD, NH3-TPD, O2-TPD, FTIR, BET, SEM, AAS, DR UV-VIS, XRD, TG-DTA, TG-DSC, CO/CO2-TPD/Chemisorption, XPS
  • In situ DRIFT and in situ FTIR spectroscopy with gas analytics (mass spectrometry and IR-spectroscopy)
  • Modern operando / in situ characterization methods: XRD, XANES, EXAFS, XRF and / or Fluorescence - XANES and EXAFS (Synchrotron radiation, XRD also conventional) combined with online FTIR, MS and GC, up to 1000°C

 

Additionally, available characterization techniques within KIT: HRTEM, TEM, Moessbauer spectroscopy, Elementar analysis; Hg-Porosimetry, EXAFS, XRF, XANES, Synchrotron-XRD, X-ray tomography.

 

Laboratory Test Benches

  • 9 Laboratory setups for catalyst tests (z.B. DOC, SCR, NSR, TWC etc.), 0,5- 70 l/min
  • 2 Stainless steel reactors for a bypass-free measurement of sintered metal discs
  • 2 Catalyst aging setups, 1-5 l/min, bis 1100°C

 

Some laboratory test benches are presented in the following in more detail:

Additional setups

  • Stationary diesel engine (DI, 3 cyl., 1000 cm3, variable load, suitable for biodiesel) to produce real diesel exhaust gas and real engine soot
  • Setup for catalytic partial oxidation (CPOX)

 

Possibility for special investigations

  • Gradient-free loop recator (CSTR) for kinetic investigations
  • Steady state and transient tests  (e.g. NSR catalysts investigations with 5 s rich- and 20 s lean cycles)
  • Isotope labeling investigations
