Présentation

En adoptant une vision systémique du secteur de la valorisation de la biomasse, associée à une connaissance approfondie des mécanismes de réaction et/ou des interactions gaz/solides, mes travaux de recherche contribuent au développement de deux axes de recherche. Le premier axe porte sur la conversion de la biomasse résiduelle brute ou déjà traitée en matériaux carbonés à valeur ajoutée (char, biochar, charbon actif, etc.) et/ou en vecteurs énergétiques. Le second concerne l'étude des procédés de purification des gaz chauds (syngas) et des fumées dans l'objectif, soit de permettre leur utilisation via des procédés de conversion énergétique (chaudières, moteurs, turbines, etc.) pour les premiers, soit de réduire les impacts environnementaux et sanitaires des émissions générées pour les seconds. Ces deux domaines sont étroitement liés par la mise en œuvre ou le développement de méthodes d'échantillonnage et de caractérisation, ainsi que par des études d'impact environnemental utilisant des outils tels que l'analyse du cycle de vie.

Mots-clés : Caractérisation de la biomasse, biochar, valorisation des ressources, étude des transferts et des réactions en catalyse hétérogène, caractérisation des gaz, traitement et purification des gaz, filtration des gaz à haute température, gazéification, pyrolyse, valorisation des déchets et de la biomasse, production de charbons actifs
