Thesis (M): The Influence of Reactive Gases and Catalysts on Selective Plastic Pyrolysis

The Sulzbach-Rosenberg branch of the Fraunhofer Institute for Environmental, Safety, and Energy Technology Fraunhofer UMSICHT develops process engineering solutions in the field of carbon conversion (next-generation biofuels, recycling technologies for plastics and composite materials, biochar), low-emission combustion and firing technology, and the provision and storage of process heat. It also has expertise in waste and resource strategies and life cycle assessment (LCA). With a focus on process engineering and plant construction, it supports clients from the project idea through pilot plants and demonstrators to market launch.

Would you like to help us create a sustainable world? We are looking for new talent! 

At the Sulzbach-Rosenberg site, various pyrolysis processes are used to thermochemically convert organic waste streams – from both biogenic and synthetic materials – into pyrolysis oils and platform chemicals. This work investigates how the selectivity and yield of high-value target products in the pyrolysis of plastic waste can be increased through the targeted use of reactive gases and catalysts. The aim is to identify optimal process conditions through systematic laboratory experiments using different feedstocks, reactive gases and catalysts/adsorbents.
