General information
Organisation
The French Alternative Energies and Atomic Energy Commission (CEA) is a key player in research, development and innovation in four main areas :
• defence and security,
• nuclear energy (fission and fusion),
• technological research for industry,
• fundamental research in the physical sciences and life sciences.
Drawing on its widely acknowledged expertise, and thanks to its 16000 technicians, engineers, researchers and staff, the CEA actively participates in collaborative projects with a large number of academic and industrial partners.
The CEA is established in ten centers spread throughout France

Job description
The design of new nuclear reactors named MSR, for Molten Salt Reactor, is currently being studied at the CEA, but also internationally. During their operation, gaseous fission products are generated and must be extracted, in particular Xe and Kr. For this purpose, adsorption on solid support in fixed bed columns are considered, but such processes require the development of very selective materials with high sorption capacities. Recently, Metal-Organic Framework (MOF) materials have demonstrated exceptional selectivity for noble gas trapping. However, such materials are generally synthesized in a fine powder form, which is not compatible with an application in fixed bed processes.
This PD works aims to synthesize MOFs and develop a shaping technique, so that they can be used in columns for the trapping and separation of noble gases. Firstly, the most promising MOF structures will be identified in the literature and synthesized in laboratory. Then a process allowing their granular shaping will be developed. This shaping will optimize the application of MOFs in a fixed bed column process and their capture performances will be determined using a gas separation pilot.
The student must have a strong interest in experimentation. He/she will develop skills in synthesis and characterization of materials (SEM, XRD, nitrogen adsorption-desorption, etc.). More generally, the student will have the opportunity to address the complexities linked to a gas treatment process using fixed bed columns.
