Continuous fast pyrolysis mini-plant


Fast pyrolysis experiments are carried out in a fully controlled, continuously operated mini-plant designed and constructed by Biomass Technology Group B.V., BTG (Enschede, The Netherlands) based on the auger reactor technology. Three types of biomass fast pyrolysis experiments were performed in this set-up, viz. non-catalytic (using hot sand as the heat carrier), in-situ catalytic fast pyrolysis (using mixtures of sand and catalyst as heat carrier) and ex-situ upgrading of non-catalytic fast pyrolysis vapours by means of a downstream, moving-bed catalytic reactor. The mini-plant enables the production of larger bio-oil samples (typically 0.3 kg/hr) suitable for a full characterization.
