Innovative Multiphase Reactor Engineering (« IRPI »)
Reaction engineering, multiphase reactors : hydrodynamics, mass transfer and reaction



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 »,
  • 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.

Application & Teaching

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).

Research supervision and co-supervision of 9 PhD students (Wang BANG, Umar HAYAT, Arunabha KUNDU, Sammy Lewis KIAMBI, Hélène CHAUMAT, Zouhir AMOURA, Matthieu ROUDET, Freddy DURAN-MARTINEZ, Pierre ALBRAND) and 3 post-docs fellows (Emmanuella BOUCHE, Marouan NEMRI, Colin BUTLER).
