Catalytic reactions are of tremendous commercial importance. Over 90% of all chemicals worldwide are manufactured with the aid of solid catalysts. Developing improved catalysts and optimizing the reaction conditions are key for improving commercial and ecological efficiency of catalytic processes.
High-pressure thermogravimetric analysis (HP-TGA) allows investigating reactions of a catalyst with the gas phase under realistic working conditions on the lab scale. Reaction conditions can include high pressure, high temperature, and reactive gas mixtures and steam. Activation and deactivation (by oxidation or coking) of a catalyst is associated with a weight change that can be measured in the HP-TGA. Simultaneously, the yield and kinetics of the reaction can be monitored by evolved gas analysis with online MS, FTIR or other methods. These data are extremely useful to optimize reaction conditions and develop improved catalyst materials.
In this webinar you will learn:
- The benefits of HP-TGA experiments for the optimization of heterogenous catalysis reactions.
- How the measurement of catalyst weight changes in a reaction can detect activation and deactivation processes.
- How you can characterize catalysts with gravimetric data in sorption and TPD/TPR/TPO experiments.
- How you can use online mass spectrometry to determine the reaction yield while you monitor the catalyst weight.
