General information

Philip is a Research Director with the CNRS

He heads the Energy and Adsorption (EnAP) group in the MADIREL laboratory

Key topics and approaches 
  • Characterization of porous solids 
  • Evaluation of adsorbent materials for potential applications in gas or vapour separation or storage
  • Adsorbent performance indicators 
  • Adsorption calorimetry
  • High pressure gas adsorption
  • Mixture gas adsorption (coadsorption)

Research activities   Highlighting the adsorption & energetic properties of nanoporous solids

Dr Philip LLEWELLYN’s research interests lie in the thermodynamic analysis of adsorption at the gas/ solid interface.

Three aspects are considered :

  • Understanding adsorption phenomena in well-ordered solids
  • Using gas/vapour adsorption for the characterization of heterogenous solids
  • The evaluation of porous materials for their eventual use in applications including the storage and separation of gases and / or vapours.
  • The role of contaminants (e.g. water) on adsorption  performance

Various approaches are taken including the development of specific apparatus to follow phenomena under pressure : Microcalorimetry, Adsorption of Gas Mixtures and other apparatus development such as a coupled adsorption-Synchtrotron XRD system. These experimental aspects are accompanied by the macroscopic thermodynamic modeling of adsorption for the prediction of mixture behaviour.


Project activity

Philip coordinates an ANR project ‘CHESDENS’, and coordinates WP3 in an EU project ‘M4CO2’.

Philip is equally active in the EU Marie Curie Network 'DEFNET' , an H2020 'Gramofon' and ANR 'Hystor' projects.

Recently accepted projects include the ANR 'MEACOPA' and ANR 'FUN'.

Many of these projects relate to the evaluation of nanoporous materials with respect to topical problems including greenhouse gas recovery, hydrogen storage and hydrocarbon separation.
