Thermal analysis with high-resolution mass spectrometry enables molecular characterisation and chemical interpretation. The analysis of PE char from an Auger reactor shows high amounts of partially pyrolyzed feedstock, releasing alkanes, alkenes and dienes. The combination of lab-based techniques with online tracing of a pilot plant was used to determine the process performance. %L 540 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00004567 %U https://purl.uni-rostock.de/rosdok/id00004567 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00004567-2 %U https://d-nb.info/1327914670/34 %U https://doi.org/10.18453/rosdok_id00004567
