Improvement of the safety of Li-ion batteries subjected to fast/cold charge constraints

The Li-ion battery is the technology selected by all car manufacturers to provide the energy storage required for electrified vehicle deployment. A battery, during its lifecycle, can encounter a wide range of operating conditions. Some of those operating conditions can accelerate battery degradation and can lead to safety issues.

Mechanistic and kinetic study of the formation of humins and their precursors during fructose dehydration

The PhD project is proposed in the context of the transformation of sugars into fine chemicals, more specifically fructose into platform molecules for the chemical industry. The goal of the project is to understand and rationalize the reaction mechanisms of sugars by combined experimental and theoretical approaches.

Etude de la désactivation de la réaction de déshydrogénation de l’éthanol

Catalyst deactivation is the loss of catalytic activity and/or selectivity with time. This is a major and recurring problem in industrial-scale processes. Catalyst deactivation is unavoidable and has a major impact on the reactor technology used and therefore on the process design.

Interactions entre les parcs éoliens et la stratification stable de l’atmosphère : impacts sur la zone d’inversion et la surface

Since 2016, a partnership was initiated between IFP Energies Nouvelles and the Centre National de Recherche en Météorologie (CNRM – Météo France), to study the interactions between wind turbines and the Atmospheric Boundary Layer (ABL).

Structure-Property Relationships of Recycled PVC

Polyvinyl chloride called PVC is the third most produced synthetic polymer in the world. This economic success is explained not only by its low production cost, the excellence of its properties but also by its versatility. This omnipresence results in the abundant generation of waste, the burial and incineration of which remain problematic.

Glycolysis of polyester waste (PET) : Inherited species catalytic activity

The PhD project is proposed in the context of PET waste chemical recycling into PET, via depolymerization. Chemical recycling is needed when plastic feedstocks cannot be mechanically processed, usually for non-transparent PET.

Kinetic modeling transfer from fossil to NET-type feedstocks using transfer learning

IFPEN aims to become a key player in the triple energy, ecological and digital transition by offering differentiating technological solutions in response to the societal and industrial challenges of energy and climate. Some of the targeted technologies are industrial processes to produce biofuels, bioproducts and the recycling of plastics.
