General information

I am a Research Director (DR1) with the CNRS and have been seconded part-time to TOTAL to coordinate an ambitious “Disruptive CO2 capture technologies” project at TOTAL.

My secondment at TOTAL is for 80% of my time to coordinate their “Disruptive CO2 capture technologies” project. Here we aim to challenge current CO2 capture methods with those based on adsorption. The aim being to directly integrate the ‘process level’ into fundamental research on CO2 adsorbent materials in order to bring mainly low TRL ideas to higher maturities. For this, I am based at the Jean Féger Technical and Scientific Centre (CSTJF) in Pau.

For the remaining 20% of my time, I will continue to work with the EnAP group at MADIREL.

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.
