Bio oil production - Fast pyrolysis
The conversion of solid biomass into liquid oil can solve many problems regarding the transport of these energy vectors or their injection into high pressure reactors such as Entrained flox Reactors. It may also become the first step for the simplified production of new liquid fuels. Fast pyrolysis is classicaly used. Research now focuses on maximising the bio oil yield and on operating with controled selectivity of produced species.Actions

Fast pyrolysis of biomass - dual kinetic models based on MicroPyrlyzer experiments
Started on October 2019
Astract: Biomass fast pyrolysis experiments are carried on in the Micropyrolyzer system. Heat and mass transfer limitations are avoided thanks to advanced modeling of the apparatus and corrections of the experimental results. It is expected that intrinsic chemical rections are characterised. Various types of models are being tested - including original ones - in order to establish acurate modelling of the biomass decomposition.
