This platform is dedicated to the valorization of wood and other lignocellulosic biomasses (straw, bark, etc.) by physico-chemical processes (hydrolysis, organosolve treatment, steam explosion, torrefaction, pyrolysis, liquefaction, etc.). The goal is the thermo-physical-chemical deconstruction of biomass for the production of materials, polymers and molecules or energy. The flagship equipments of this platform are:
- a complete characterization of biomasses (ashes, macromolecules, volatiles, etc.) and their shaping (grinding, granulation, etc.)
- a unique prototype of steam explosion at laboratory scale;
- a high-pressure reactor assembly (up to 200 Bar of hydrogen), batch and continuous, for the study of biomass depolymerization and hydrogenation, with in-situ analysis;
- pyrolysis and pilot gasification reactors up to 50 kg/hour;
- a set of analysers unique in Europe for the analysis of liquids and gases: liquid (including semi-preparative) and gas chromatography, numerous mass spectrometers including a unique laser photoionisation spectrometer.
Hydrotreatment and depolymerization platform
The applications and fields of activity concern :
- Synthesis and reactive extrusion of biopolymers
- Pretreatment of lignocelluloses prior to hydrolysis and fermentation for the production of liquid biofuels or platform molecules for chemistry and materials
- Depollution of wood from recycling for energy or material applications
- Energy densification through the production of black pellets
- Depolymerization of cellulose and lignin
- Production of biochar, bio-oils and syngas.
- Production of chemical molecules with high added value by catalysis
