IFP Energies nouvelles - Lyon

Stage Chimie Rhône entre février et juillet 2023 de 5 à 6 mois


IFP Energies nouvelles (IFPEN) est un acteur majeur de la recherche et de la formation dans les domaines de l’énergie, du transport et de l’environnement. De la recherche à l’industrie, l’innovation technologique est au cœur de son action, articulée autour de quatre priorités stratégiques : Mobilité Durable, Energies Nouvelles, Climat / Environnement / Economie circulaire et Hydrocarbures Responsables.

Dans le cadre de la mission d’intérêt général confiée par les pouvoirs publics, IFPEN concentre ses efforts sur :

  • l’apport de solutions aux défis sociétaux de l’énergie et du climat, en favorisant la transition vers une mobilité durable et l’émergence d’un mix énergétique plus diversifié ;
  • la création de richesse et d’emplois, en soutenant l’activité économique française et européenne et la compétitivité des filières industrielles associées.

Partie intégrante d’IFPEN, l’école d’ingénieurs IFP School prépare les générations futures à relever ces défis.

Towards carbon circularity via waste py-oil upgrading: understanding and predicting matrix effects

The internship project is placed in the context of recycling and recovery of hydrocarbon products from wastes such as used tires and used plastics. A possible way of reprocessing concerns the pyrolysis oils (py-oils) resulting from these products. These, although they can be considered as unconventional, have a calorific value at least like current fuels and are chemically stable. Thanks to the highly valuable character, these py-oils can also be used as a basis for the production of hydrocarbon feedstocks by introducing them into existing refining processes such as hydrotreating and hydrocracking

Nevertheless, as they are new feedstocks, these py-oils contain new heteroatom containing molecules for which it is necessary to know the reactivity and the inhibition power, especially during the hydrotreating step. The objective of the thesis is therefore to identify the most refractory compounds and to estimate their reactivity. A model will be developed taking into account the inhibition between all reactions. One type of compound will be particularly targeted: nitrogenous molecules because they are strong inhibitors regarding the cracking catalyst.

To achieve this objective, this internship aims to develop a methodology to evaluate the reactivity of py-oils. Batch tests will be carried out to establish a preliminary kinetic model. Advanced analytical techniques will be used to characterize the effluents, as well as numerical, mathematical and chemical engineering models to try to identify the various contributions to the intrinsic kinetics as well as to the global kinetics of transformation of the impurities present in the py-oils. This internship might be continued in a PhD.
