Investigation and enhancement of conventional multiphase reactors :

• multiphase flows
• bubble columns and bubble reactors which potentially include catalyst (fixed bed or slurry reactor)
• coupling between hydrodynamics, interfacial mass transfer and chemical reaction.
• Implementation of dedicated experimental methods for the local investigation of flow and mass transfer : specific sensors or high resolution optical techniques; context : LGC and FERMaT research federation (« Fluides Energie Réacteurs Matériaux et Transferts », http://www.federation-fermat.fr)
• Phenomenological models for flow and transfer (with or without reaction) in multiphase reactors

Monolith-type devices : catalytic reactors with in situ heat exchange, gas-liquid contactors

• Assessment of new skills in the field of monolith devices : specific design of fluid distributor, dedicated fast sensor for fluid distribution characterisation, options with SLM technique to manufacture monolith blocks in metal.
• Measurement/modelling of yield and selectivity for catalytic gas-liquid reactions in monolith apparatus.
• Measurement/modelling of gas-liquid mass transfer for gas absorption purpose.

Research interest: Investigation and modelling of multiphase reactors as bubble columns or catalytic reactors; design of pilot-scale units; implementation of dedicated experimental methods as Planar Laser Induced Fluorescence with dye Inhibition (PLIF-I technique).

Applications: treatment of fossile and bio-sourced hydrocarbons (petrochemistry, food industry, synthesis of end-use products).
