ISASF, ou A.I.P.F.S., Association Internationale pour la Promotion des Fluides Supercritiques, est une association à but non lucratif qui vise à promouvoir connaissances et applications des fluides supercritiques.

Annonces

An opportunity for a post-doctoral researcher in the field of thermal separations technology at the Department of Process Engineering at Stellenbosch University is currently available. The focus of the position would be on thermodynamics, phase behaviour, distillation and/or extraction principles with particular focus on high pressure/supercritical applications. The position will be awarded initially for a period of one year but may be extended based on performance and availability of funds.

The postdoctoral researcher would be required to conduct research and provide significant assistance with the following:

  • Supervision of postgraduate student projects;
  • Assist with the management of the research group;
  • Performing experimental work when necessary;
  • Publication of research outputs from research generated;
  • Developing new areas of research within the research group;
  • Improving experimental facilities;
  • Writing new funding proposals to sustain research activities

RECYCLING OF POLYMER COMPOSITES BY MEANS OF A SUPERCRITICAL FLUID TREATMENT

The subject of this PhD is to study and develop a supercritical fluid process for the recycling of carbon reinforced plastic composite, both resins and fibers. Use of composite materials is increasing in a wide range of applications : industrials, sporting, automotive, aeronautical, marine…but the lack of recycling for those non biodegradable materials is an environmental burden. Since 20 years several treatments have been developed for composites wastes, mechanical, thermal processes like pyrolysis and thermochemical like solvolysis. This process is able to breakdown the composite polymer matrix and hence allow the recovery of the fibers. Supercritical fluids are used due to their high diffusivity in porous materials combined to their chemical reactivity. The objective of this work is to define the necessary process conditions for deconstruction of composite resins of carbon fibers reinforced plastic composites. The aim is  to recycle the fibers and also to allow a further chemical valorization of resins decomposition products. This work include a detailed analysis of the organic molecules produced and the development of a chemical mechanism for this depolymerisation. Mechanical properties of fibers after treatment will be determined to validate the recycling interest. This work will provide finally a first technico-economical evaluation of the proposed process.
