Analytical methods for product and catalyst characterization
The application of gas chromatographic analysis methods with various detectors allows for the qualitative and quantitative analysis of permanent gases, hydrocarbons, functionalized organic as well as sulfur compounds. Measurements can be conducted online by coupling with lab and pilot plants. Offline analysis is possible for gaseous, liquid and solid samples.
For the continuous analysis of gas concentrations in plants and prototype systems, several other analysis methods besides GC are available.
Additionally, several methods for the characterization of heterogeneous catalysts are available at IKTS. The application allows for the correlation of experimental results on catalytic activity with the catalyst properties and therefore a targeted optimization.
