Masterthesis: Development of a kinetic model for solvent-assisted depolymerisation of polycondensati

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research institutions throughout Germany and is the world's leading applied research organization. Around 30 000 employees work with an annual research budget of 2.9 billion euros. As one of the oldest and largest Fraunhofer institutes, the Fraunhofer Institute for Chemical Technology ICT has special expertise: by linking the diverse research fields of polymer engineering, chemical processes, explosives technology, safety and security, and energy and drive systems, it achieves decisive breakthroughs. Examples can be found in lightweight construction for mobility, in environmentally friendly chemistry, in applications for the aerospace and military sectors as well as in life-cycle assessments, recycling and sustainability concepts - which you could soon help to create! Polycondensation polymers are used in different walks of human life. However, post-consumer plastic waste resulting from their indiscriminate use and inappropriate disposal poses a great threat to our environment. Chemical recycling it to obtain constituent monomers and/or other valuable chemicals renders these waste streams as a valuable feedstock for the chemical industry and paves way towards a resource-efficient future. Our group develops sustainable chemical recycling strategies for different poly-condensed fractions commonly present in conventional waste streams. These strategies involve the use of auxiliary solvents to aid polymer dissolution and nucleophilic process reagents for subsequent depolymerisation. These processes, thus, involves an interesting inter-play between mass-transfer and reaction, which has to be investigated and further modelled within the framework of this thesis. The ultimate goal is to develop a holistic yet simple kinetic model for solvent-assisted depolymerisation of different polycondensation polymers already developed at Fraunhofer Institute for Chemical Technology (ICT). What you will do * Comprehensive literature research on the current state-of-the-art technologies for kinetic analysis in efforts directed towards chemical recycling (solvolysis) * Determining the reaction kinetics for solvolysis of at least one poly-condensed polymer and its subsequent kinetic modelling * Analysing the sensitivity of the model to different degrees of freedom * Contributing to a publication to disseminate the scientific findings What you bring to the table * Degree in Chemistry or Chemical and/or Process Engineering * Interest in subjects like Chemical Reaction Engineering, Process Modelling and Optimization, Circular Economy and Sustainability (Green Chemistry) * Practical laboratory experience * Proficiency in modelling tools like MATLAB® * Motivation to establish this topic further at Fraunhofer ICT * Dissemination of the results through appropriate publications and/or at relevant conferences What you can expect * a challenging, attractive, interdisciplinary and international working environment * an appreciative and supportive working atmosphere * Opportunities for individual development - flexible working hours thanks to flexitime agreements * Parking spaces, canteen and library on campus * ... and much more! The maximum weekly working time is 20 hours and can be arranged flexibly. Remuneration according to Research assistant pay (dependent on qualifications).
