in-situ Catalyst Characterization System (ICCS)

in-situ Catalyst Characterization System (ICCS)

The ICCS is an advanced catalyst characterization tool that allows the user to study the impact of a reaction on critical parameters such as number of active sites, under precisely controlled, process-representative conditions. A standalone system designed to complement the MicroActivity Effi, the ICCS adds two new capabilities: Temperature Programmed Analyses (TPx) and Pulse Chemisorption. These well-known and time-tested techniques may now be performed on a fresh catalyst and then performed on a used catalyst without the need to remove the material from the reactor. This strategy provides a method for comparing the catalyst and the number of active sites before and after use. Users benefit from obtaining both temperature programmed analyses and pulse chemisorption data for the same aliquot of sample used for their reaction studies. Performing these analyses in-situ virtually eliminates the possibility of contamination from atmospheric gases and moisture which may damage the active catalyst.

ICCS – KEY FEATURES & BENEFITS

  • in-situ characterization under reaction conditions (temperature and pressure) of catalysts, catalyst support and a variety of other materials without sample needed to be exposed to the external environment.
  • A wide variety of tests can be performed including pulse chemisorption, temperature – programmed reduction (TPR), desorption (TPD), and oxidation (TPO).
  • Multiple characterizations of the same catalyst may be performed using the same sample.
  • A high precision Thermal Conductivity Detector (TCD) to monitor changes in the concentration of gases flowing into and out of the sample reactor.
  • Fully automated flow and integrated pressure controller for real-time control.
