Production and recycling of composite materials based on polymers and fibres: assessing the chemical complexity by thermal analysis and high end mass spectrometry Friederici, Lukas , 1996- (VerfasserIn) Zimmermann, Ralf , 1963- (AkademischeR BetreuerIn) Jänis, Janne (AkademischeR BetreuerIn) Universität Rostock (Grad-verleihende Institution) Universität Rostock Mathematisch-Naturwissenschaftliche Fakultät (Grad-verleihende Institution) Text theses Text Hochschulschrift 2023 2023 eng ger electronic resourceremoteComputermedienOnline-Ressourceapplication/pdf1 Online-Ressource (verschiedene Seitenzählungen) Illustrationen, Diagramme Different lifecycle steps of products (polymers/composites) were described with pyrolysis-based analytic techniques for their chemical nature and the possibility of improving current production or recycling processes. 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.<eng> Open Access Urheberrechtsschutz 1.0 vorgelegt von Lukas Friederici Enthält Zeitschriftenartikel GutachterInnen: Ralf Zimmermann (Universität Rostock, Institut für Chemie) ; Janne Jänis (University of Eastern Finland, Department of Chemistry) Dissertation Universität Rostock 2023 Kumulative Dissertation 540 668.41 660 https://purl.uni-rostock.de/rosdok/id00004567 https://doi.org/10.18453/rosdok_id00004567 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00004567-2 https://d-nb.info/1327914670/34 Production and recycling of composite materials based on polymers and fibres--(DE-627)1885859619 urn:nbn:de:gbv:28-rosdok_id00004567-2 doi: 10.18453/rosdok_id00004567 oclc: 1429923935 ppn: (DE-627)1885848609
